How to Speed up Healing: From Sunburns to Surgery Recovery

The wound healing process, much like our physical activity levels, tends to decline as we age. Here are some scientifically backed tips on the best ways to speed up healing, from minor cuts and scrapes around the home, to post-surgical recovery and muscle tissue rebuilding.

Whether you have a cut, a burn, or are healing from a surgical procedure, there are ways to help speed up healing and close your wounds faster. The wound healing process, much like our physical activity levels, tends to decline as we age. The older we get, the longer our healing time takes, leading in some instances to chronic wounds that never really go away. To speed up wound repair, here are some tips for helping your body along.

Speed up healing: from sunburns to surgery.

At-Home Healing: Small Wounds and Scar Reduction

When it comes to home remedies for wound care, there are a lot of old wives’ tales still around. Some of them make a certain amount of sense when considered scientifically, like waiting 30 minutes to swim after you eat may well help you avoid a minor cramp. However, not all of these folktales are true enough to keep repeating or insisting on. Not everyone will get a minor cramp if they swim after eating, and even if they do, it won’t cause them to drown. And yet still we wait, and tell children to wait, and keep the myth going.

When it comes to how to speed up wound healing, there are a lot of practices that don’t really apply. Some say leaving a wound open to dry in the air and “breathe” helps it heal faster, but that isn’t true if it’s now open to dirt and possible infection. To stop infection, many douse a wound in alcohol or peroxide—talk about pouring salt on a wound!

In truth, leaving a wound to dry out is not ideal, and can even slow healing and increase pain. Wounds need moisture to heal, and moist wound healing speeds up healing and reduces scarring. Here are some other tips on how to foster faster healing and reduce the risk of scarring.

1. Clean and Disinfect

Before touching a wound, wash your hands. When it comes to cleaning the wound, start with clear water and a clean cloth to remove any dirt or particles from the wound. If there are pieces of debris in a wound (your kid took a wipeout on their skateboard and has gravel embedded in the scrape, for example), use a pair of tweezers to remove them. The tweezers should be sterilized with some isopropyl alcohol, but alcohol is not advised directly on the open wound.

Instead, once the wound is clean, apply an antibiotic cream, ointment, or spray to the wound area, and make your call about what kind of bandage applies. If it’s an open wound like a wide scrape, a gauze and a wrap may be called for, but a cut on a finger might need only a bandaid to reduce the risk of infection and speed healing.

Remember not to pick at any scab that forms, because a scab is the body’s natural bandage.

2. Encourage Blood Flow

Nobody can heal you better than your own body, but there are ways to help it along. You’ll notice when you get a scrape or a bruise that the area seems to heat up. That’s because the body has dispatched its in-house medical team via your bloodstream.

To increase blood flow to the skin and surrounding area, you can apply a heating pad or hot water bottle, or place the wound area in some warm water for 15-30 minutes. It’s not a high-tech method but it does help, especially for wounds on your extremities (fingers, toes, arms, and legs) where your blood vessels are smaller, or for anyone with poor circulation, like the elderly.

If adding heat is uncomfortable, massaging the surrounding area is another way to usher blood to the site of injury.

3. Reduce Inflammation

After encouraging healthy blood flow, your wound may experience unhealthy inflammation. A burn that you got from pulling dinner out of the oven might feel like it’s still burning for days after, and you’ll want some kind of anti-inflammatory to help relieve the pain.

Many people think of the gel-like insides of the aloe vera plant for burns, and this is an age-old home remedy that actually works! Aloe vera is a succulent plant originally native to Africa that has a gooey substance in its leaves called mucilaginous juice, and while the plant is 99% water, it does have two chemicals within that improve wound healing.

According to researchers, many of the healing effects of aloe vera are due to the glycoproteins and polysaccharides present in the plant’s pulp. The polysaccharides increase cellular movement, leading to faster tissue regrowth, and the glycoproteins help relieve pain and control the inflammatory response. Together these compounds aid and possibly improve your immune system.

There is even more evidence out of a 2015 study that suggests there are further helpful compounds in aloe vera for cutaneous wounds (like sunburns). For instance, glucomannan stimulates the growth of fibroblasts responsible for collagen, skin cell, and tissue building. Other chemicals found in aloe vera may also help foster blood vessel regrowth, making it a fantastic, natural anti-inflammatory to have on hand for minor wound healing.

4. Get More Protein, Vitamins, and Nutrients

There are certain power foods that contain the nutrients your body needs to rebuild itself, including vitamin C, vitamin D, vitamin E, omega-3 fatty acids, and magnesium. You’ll find these nutrients in dark green leafy vegetables and in orange, yellow, and red fruits and veggies (eat the rainbow!), like bell peppers, tomatoes, oranges, and more.

One of the biggest factors when it comes to tissue and wound healing though? Protein. Omega-3s come from fish along with fish’s protein content, and you can get an assortment of your essential amino acids from various meats and dairy products.

Amino acids are needed for wound healing, so if you’re not a meat-eater, you can increase your protein intake with certain vegetarian and vegan protein foods, or with an amino acid supplement while you heal.

How to Speed up Healing After Surgery

Outside of household and playground injuries, recovery after surgery is a whole different ball game. No matter where it is on the body or how good the chances for a speedy recovery are, surgery still carries a certain amount of risk, and so does surgical recovery. Once you’re sent home from your procedure, you’re going to want to heal as quickly and safely as possible. Here are some tips for how to do so.

1. Follow Your Doctor’s Instructions

While it’s true that no one knows your body quite like you do, doctors don’t give out suggestions willy-nilly. Their medical advice is based on data and research collected from all different kinds of patients over years and years of procedures.

If a doctor tells you to avoid activities for a specific amount of time after a procedure, it’s in your best interest to heed that advice. If you’re told to avoid driving, avoid sexual intercourse, avoid alcohol, or avoid lifting anything over 10 pounds for a couple of weeks, this is for your safety, and so you don’t end up back in their office with a new injury or complication. You may be feeling good enough to return to normal activity, and that’s great, it means your healing is right on course! And yet there may still be healing processes going on beneath your skin that need a little bit more time.

2. Eat the Right Recovery Foods

As true as it was for minor wounds, eating a nutrient-dense diet is even more important after a surgery, because you’re healing much deeper wounds. Although you may have a loss of appetite or digestive discomfort after a surgery, it’s important that you eat a healthy diet by any means necessary (broths, smoothies, amino acid powders), because certain foods are actually going to feed your recovery process.

Again, vitamin C and zinc can help with healing, and can be had from fruit and beans. Iron and vitamin B12 help in forming new blood cells and can be found in fish and eggs. Sports and sugary drinks should be avoided for the time being, as should refined sugar foods.

Protein is more important than ever, as many surgeries by nature involve cutting through tissue and muscle, and the amino acids in protein can help speed post-surgical recovery. Meat, poultry, fish, and eggs are all strong sources of protein, but if a doctor tells you to take a protein supplement, look for a comprehensive amino acid supplement. For recovering after surgery, you may need more protein than a normal diet or your appetite can provide, and supplementing may be a necessity.

3. Follow-up, Ask For Help, and Get Moving Gradually

Surgical recovery may take a while and involve follow-up appointments, physical therapy, and/or at-home assistance. During this time, it’s important to keep all appointments with your health care team, because a diagnostic such as bloodwork could alert your doctor to a problem before it becomes an infection. Likewise, physical therapy could help you correct something like a limp before it becomes a misalignment.

Asking for help from your family or your medical team may not be your usual tendency, but it is necessary and encouraged for the sake of a speedy and successful recovery. If problems are allowed to fester, you could end up back in the hospital or on bedrest, and in danger of new problems altogether, like muscle atrophy.

4. Don’t Smoke

This is a tip that may not apply to all, so if you don’t smoke or have never smoked, skip ahead. However, if you are a smoker or live with one, the effects of cigarette smoking can counteract your wound healing.

Nicotine tightens blood vessels, and the more constricted your blood vessels are, the harder it is for all the other recovery work you’re doing to matter. The nutrients you eat won’t be going to the right places, the muscle you’re building takes longer to thrive, your wounds take longer to heal, and more carcinogens and harmful substances are coming in at the same time. If you’ve ever wanted to quit smoking, after a surgery it’s more important than ever, and can make even more of a positive health impact.

The Need for Speed

Some things can’t be rushed, and a lot of the time your health is the tortoise racing against the hare: slow and steady wins the race. Diet and exercise are long-haul habits that make all the difference. While that’s also true when it comes to a lot of aspects of healing, the more you can do to support your body’s healing mechanisms and get out of their way, the faster the process goes and the lower the chance you’ll have any more problems arising from the initial issue.

Whether it’s a cut, a sunburn, a broken limb, or a surgical operation, anything can go from bad to worse if you’re not careful. Luckily there are resources you can use and advice to be had on how to speed up healing in a successful and sustainable way. Take these tips into consideration, seek medical advice if needed, and know that we wish you a speedy recovery.

Caffeine Withdrawal: Symptoms and Solutions

Learn about the symptoms of caffeine withdrawal, ranging from mild to severe. Also check out some tips on how to wean yourself from caffeine without the discomfort of withdrawal.

If you’ve ever had a coffee or soda habit, you may have experienced caffeine withdrawal symptoms. They’re uncomfortable, sometimes flu-like symptoms that can distract you from your work, disrupt your sleep, and make you irritable around your loved ones. Because coffee and soda are such normal beverages around the home and workplace, it can be easy to forget that caffeine, though mild, is still a drug just like any other. In fact, the American Psychiatric Association included “Caffeine Withdrawal” in a recent edition of the Diagnostic and Statistical Manual of Mental Disorders (the DSM-51), a publication for health care professionals that describes the criteria of mental disorders. Caffeine withdrawal causes real symptoms in the human body, and this article will describe some of those symptoms, and a few different methods you can use to relieve them.

Caffeine withdrawal: symptoms and solutions.

Common Symptoms of Caffeine Withdrawal

Caffeine is a stimulant to the central nervous system, and it is also the world’s most commonly used psychoactive substance. Caffeine affects your neural activity, increasing alertness and reducing fatigue. If you regularly consume caffeine your body begins to rely on it, and when you stop, you can experience withdrawal. Here is a list of some common symptoms of caffeine withdrawal.

1. Headache

One of the most commonly reported symptoms of caffeine withdrawal, headaches are caused because caffeine constricts blood vessels in the brain, slowing the blood flow. One study showed that those who consume fewer than 3 cups of coffee a day can reduce their cerebral blood flow by up to 27%. Once the blood vessels narrow, reducing your caffeine consumption allows the blood flow to increase to the brain again, which can cause painful, sometimes severe headaches as the brain readapts. The headaches will eventually subside, but read to the end of this article to find our suggested solutions for relieving the symptoms of caffeine withdrawal.

2. Difficulty Concentrating

Coffee, tea, and energy drinks with caffeine are often taken to boost concentration, so when you suddenly stop consuming them, that benefit ends. Caffeinated beverages are often used to improve focus before tests, athletic events, or presentations because caffeine causes your adrenal glands to up their production of adrenaline. Caffeine also boosts your excitatory neurotransmitters, norepinephrine and dopamine. Overall, caffeine works by raising your heart rate, your blood pressure, and stimulating your brain. Phasing out caffeine forces your body to suddenly adapt to doing without all those perks.

3. Fatigue

That feeling of tiredness you often use a cup of coffee to counteract? If you quit caffeine, that fatigue may return with a vengeance. Caffeine increases alertness by blocking adenosine receptors, a neurotransmitter that causes drowsiness. When that is removed from your body’s chemistry, the adenosine comes right back, and affects you in a way you may have become unaccustomed to dealing with on your own.

One study of 213 habitual caffeine drinkers showed that abstaining from caffeine for only 16 hours caused feelings of fatigue. Those who consumed caffeine the most had much more severe withdrawal symptoms. Because the energy caffeine provides only lasts up to 4-6 hours, it becomes easy for normal users to get into the habit of drinking multiple cups of coffee or energy drinks each day, just to maintain their desired level of alertness. It also deepens their dependency.

4. Anxiety

Because caffeine is a stimulant that increases your blood pressure, heart rate, and the stress hormones epinephrine and cortisol, just 1 cup of coffee can make some people anxious and jittery. However, suddenly stopping your caffeine consumption can cause this side effect as well, as your body has become physically and mentally dependent on a substance it’s no longer getting. Moreover if you take your caffeine in the form of soda or sweetened coffee you may be feeling the lack of sugar intake as well, which could amp up the restlessness and anxiety you feel and make your caffeine withdrawal even worse.

5. Irritability

Regular coffee drinkers are often cranky or irritable before their morning cup of java. It’s a lack of caffeine that may be the cause of that, because caffeine only lasts in your system for 4-6 hours and it’s worn off after a night’s rest. As coffee drinkers are used to the mood-altering effects of caffeine, the lack of it can bring feelings of irritability. One study of 94 caffeine drinkers who wanted to cut back on their caffeine intake showed that 89% of the participants were unsuccessful, reportedly due to the symptoms of withdrawal, which included anger and irritability.

6. Depressed Mood

Caffeine is well known for perking people up and elevating their mood because it blocks adenosine receptors. Studies have shown that those who consume caffeine regularly have a more positive mood compared to those taking a placebo. It can go so far as to reduce the risk of depression, as seen in one study on over 50,000 women which found that those who drank 4 or more cups of coffee a day had a 20% lower risk of depression. Removing those benefits by ceasing caffeine consumption can cause a depression in mood, a side effect that could be quite dangerous, as depression is a serious condition that could alter someone’s life for the worse.

7. Tremors

Another serious side effect of caffeine withdrawal: tremors. Those with a serious dependency may find their hands shake after they quit caffeine, because caffeine is a stimulant of the central nervous system. Quitting cold turkey could be ill advised for those with anxiety disorders or a long-term caffeine addiction, as these hand tremors could last between 2 and 9 days after stopping caffeine intake. Tremors lasting any longer than that may mean you need to consult a medical professional to make sure there isn’t an underlying cause beyond consuming too much caffeine.

Ways to Reduce Caffeine Withdrawal Symptoms

Here are some tips for treating caffeine withdrawal symptoms.

1. Over-the-Counter Medications

For headaches or difficulty falling asleep, over-the-counter medications like pain relievers and sleep aids can help in the short term, to get you past those first few days of caffeine withdrawal. Ibuprofen (Advil), acetaminophen (Tylenol), and aspirin (Bayer) can help a caffeine withdrawal headache, but be sure to take them as instructed on the label, as some medications can cause stomach bleeding or kidney damage if overused.

2. Reduce Slowly and Stay Hydrated

Reducing your dependence on caffeine slowly is a way to minimize withdrawal symptoms while avoiding over-the-counter drugs. If you are drinking multiple cups of coffee a day, for example, you may want to take a month and reduce your caffeine consumption by 25% each week. That means 4 cups a day on a usual week should go down to 3 cups the next week, and so on until you can experience milder withdrawal symptoms. Switching to decaf or herbal tea after that can help you keep your habits and obey your taste cravings, and staying hydrated reduces instances of headache.

3. Amino Acids for Caffeine Withdrawal

Another option you might try is supplementing with the amino acid L-tyrosine for caffeine withdrawal (also known as tyrosine). Your brain synthesizes dopamine from tyrosine, which is normally gained from either high-protein food sources (cod, eggs, spirulina, beef, poultry, pork, dairy products, avocados, nuts, and seeds), or from another amino acid, phenylalanine.

The brain overproduces dopamine when you consume caffeine, first depleting your stores of tyrosine, then phenylalanine. When you stop caffeine consumption suddenly, your body may be unable to normally produce dopamine for a short time until it replenishes its amino acid stores.

Supplementing with a comprehensive amino acid supplement that includes tyrosine or phenylalanine (which helps restore both of them), could help you quit caffeine cold turkey, but without the cravings and withdrawal symptoms.

The last facet will be to replace the behaviors around caffeine consumption: heading to a coffee shop, having a soda as a midday pick-me-up, or relying on energy drinks when you need to focus. Replacing behavioral habits with new ones, and replacing your physiological dependence with the help of an amino acid supplement, may allow you to skip the backlash of removing daily caffeine from your life (and help keep you from backsliding into a habit you no longer want to participate in).

Remove Caffeine from Your Routine

Caffeine dependence is a very common predicament in the modern world. Most people are able to kick the habit on their own eventually, but relapsing is a common occurrence too. Consider using the tips above to stick to your new caffeine-free resolution, and consult a medical professional if you notice extreme withdrawal symptoms like double vision, confusion, or nausea, especially if they persist for longer than 9 days. Other than that, quitting caffeine is definitely doable, and you know you have the strength to see it through.

Muscle Atrophy: Causes, Treatment and Prevention

Learn about what causes muscle wasting or muscle atrophy, and how best to prevent and treat this condition, including through the use of physical therapy, medical intervention, and staying active. 

Muscle atrophy is essentially muscle wasting: it’s what happens when your muscles waste away, frequently as a result of a lack of physical activity. This article will explore the causes and symptoms of muscle atrophy, as well as preventative steps people can take if they’re immobile or bedridden due to illness. Loss of muscle mass or muscle strength can be particularly devastating for those who are already in positions of compromised health, and so in an effort to help you maintain your quality of life, we’ve compiled the relevant information here.

Muscle Atrophy: Definition

Atrophy of the muscles occurs when a person is inactive for so long that their skeletal muscles (these are the muscles attached to your bones which literally make your skeleton move) begin to break down, and the muscle protein is cannibalized by the body. This can happen in small instances or large, catastrophic instances.

Muscle atrophy of the hand or forearm may occur if you spend weeks in a cast to heal a broken arm, which is why people in casts are given exercises to do while they’re immobilized to prevent protein degradation in their muscles and muscle wasting. Muscle atrophy of the legs or muscle atrophy of the thighs can happen on a much larger scale to those who become wheelchair-bound, either temporarily or due to becoming permanently paraplegic. In even more extreme cases, those who have been held as prisoners of war may have full-body muscle wasting due to confinement and malnutrition for significantly long periods, sometimes years.

Muscle atrophy is a decrease in muscle mass, either partial or complete, which is most commonly suffered when a person becomes disabled or their movements severely restricted. This makes it difficult or impossible to move the part of the body where the muscle has atrophied, and medical advice should be sought for solutions.

Muscle atrophy: causes, treatment, and prevention.

Muscle Atrophy: Causes

Significant decreases in activity levels can lead to muscle atrophy, and there are many situations where that can occur, causing what’s known as disuse atrophy. There are also instances of muscle atrophy due to medical conditions that inhibit the use of a body part, and even rarer causes like the muscle atrophy experienced by astronauts after relatively short periods (a few days) of weightlessness. Muscle atrophy in situations of being bedbound or ceasing intense physical training can come on in as little as 2 weeks. Some of the other causes of muscle atrophy are as follows.

  • Lack of physical activity
  • Advanced aging
  • Malnutrition
  • Stroke
  • Alcohol-associated myopathy
  • Burns
  • Temporary disabling injuries (broken bones, torn rotator cuff)
  • Permanently disabling injuries (severed spinal cord, peripheral nerve damage)
  • Prolonged corticosteroid therapy

Some of the diseases and medical conditions that can disrupt or restrict movement, thus leading to muscle atrophy, include:

  • Spinal muscular atrophy: A hereditary wasting disease of the limbs.
  • Osteoarthritis: Degeneration of bones and joint cartilage that leads to decreased movement.
  • Polymyositis: An inflammatory disease of the muscles.
  • Amyotrophic lateral sclerosis (ALS or Lou Gehrig’s disease): Compromises the nerve cells of the spinal cord.
  • Muscular dystrophy: A hereditary disease that causes muscle weakness.
  • Multiple sclerosis (MS): An autoimmune disease that destroys the protective sheathing of brain and spinal nerves.
  • Rheumatoid arthritis (RA): A chronic inflammatory disease of the joints.
  • Dermatomyositis: Inflammation of the skin and underlying muscle tissue.
  • Polio: A virus afflicting muscle tissue, which can lead to paralysis.
  • Cancer cachexia: The weight loss, lack of energy, and loss of appetite in someone undergoing cancer treatment.
  • Guillain-Barré syndrome: An autoimmune disease and form of polyneuritis, which leads to paralysis of the limbs.
  • Neuropathy: Nerve damage that results in loss of sensation or functioning.

Muscle Atrophy: Symptoms

Regardless of the cause, these are the symptoms that may alert you to possible muscle atrophy, after which a trusted medical professional should be sought for advice.

  • One of your limbs (arms, legs) appears markedly smaller than the other one.
  • You’ve spent a long time physically inactive (bedridden, hospitalized).
  • You’re experiencing noticeable weakness in one limb.

Not to be flippant about the subject, but there is some truth to the phrase “use it or lose it” when it comes to muscle. If you cannot move your muscles with regular physical activity, you will start to lose them.

Muscle atrophy pain may or may not be a symptom, as that depends on the cause of the atrophy. Many people will begin to lose muscle before they are aware it’s happening, and will have to rely on visual muscle size to realize they need medical attention.

Muscle Atrophy: Diagnosis

Once you’ve gotten in contact with a medical professional, the diagnosis may involve your full medical history, a review of any previous injuries, as well as an evaluation of your symptoms. Diagnosing the atrophy may also involve diagnosing the underlying medical condition, which may require blood tests, X-rays, MRIs, CTs, a nerve conduction study, or a muscle and/or nerve biopsy to find out what could be causing muscle atrophy if it’s not readily apparently (as it would be if you’d suddenly become bedbound).

Can Muscle Atrophy Be Reversed?

Depending on the cause, yes. There are some cases where a proper diet, exercise, and physical therapy can not only reverse muscle atrophy, but also prevent it from recurring. However, this will not be the case in some disease-related forms of atrophy, and it is important that you consult your doctor on what your expectations for muscle atrophy recovery should be in restimulating protein synthesis and rebuilding your muscles.

Muscle Atrophy: Treatment

Again, this will depend on the diagnosis of the cause, and also the severity of your muscle loss, but the treatments for reversible muscle atrophy may be as follows.

  • Physical therapy
  • Exercise
  • Ultrasound therapy
  • Dietary changes
  • Surgery
  • Electrical stimulation

If a lack of movement caused this condition, regaining movement will go a long way towards fixing it, and moderate exercise like walking, along with physical therapy, may be a way to regain muscle strength without needing surgery to fix skin, tendons, or ligaments too tight to begin moving again (as in cases of contracture deformity that could be caused by malnutrition or burn injury scar tissue).

Muscle Atrophy: Prevention

There are ways to prevent muscle atrophy before it happens, and ways to guard against it if you were fortunate enough to recover your musculature after one instance of muscle loss. If preventing muscle atrophy is in your control (and, of course, sometimes it will not be), here are a few ways to maintain muscle strength in adverse circumstances.

Stay Active

If you’re in recovery from a severe illness or have just come home from the hospital after a debilitating accident, it’s not as if you’ll take up jogging right away. However, movements as small as walking to your mailbox each day, or around the block, or up and down a single flight of stairs, can truly make the difference in the long run when it comes to maintaining your mobility.

Stay Nourished

Depending on your condition, this may be difficult, but when your body lacks the proper nutrition to stay running, it will start to catabolize your muscles for its needs, which is a form of self-cannibalization or destructive metabolism that literally eats away at your muscles. Make sure you’re getting proper protein, if not from whole foods, then in the forms of protein shakes or supplements, as every little bit may help.

In fact, supplementing with amino acids has been proven to help accelerate muscle recovery in times of sickness and illness and can help boost your muscle-building gains. To learn more about amino acid therapy for muscle atrophy, give this informative article, written by one of the world’s foremost amino acid researchers, a read.

Seek Physical Therapy

Physical therapy is particularly valuable for those with severe injury recovery (such as a car crash survivor) or a neurological condition, as therapists provide professional guidance on what, and how, and how often to stretch your body to build strength.

Try Passive Movement

Another way physical therapy can help you even before you have the strength to help yourself is with passive movement. Passive movement requires the therapist to gently move your legs and arms for you. This is how you can begin to recover from a very deep muscle deficit and build up strength and muscle again.

Preventative Measures

Not only will the above advice help prevent muscle atrophy, but it can also help discourage bedsores in those who are bedridden due to illness, and reduce the chances of developing dangerous blood clots in the limbs. Likewise, these movements may prevent muscle stiffness, retraction, and nerve damage. Consult a medical professional or licensed physical therapist for more advice.

Eliminate Atrophy

If you are in danger of muscle atrophy, take steps to make sure your protein intake and nutrients are sufficient, including the use of a supplement if necessary, like Amino Co.’s essential amino acid supplement, which contains all of the essential aminos required to build new muscle cells and structures. Also, make sure that you stay active, no matter in how small a way, to preserve your muscle function and prevent your muscles from falling into complete disuse. You cannot always control your body’s condition, but if the type of atrophy you fear is the type that’s preventable, it’s well worth the effort to maintain the quality of life and movement you’ve come to expect.

Are Beans a Complete Protein?

Find out whether beans are a complete protein, and also learn about the health benefits that beans have to offer for weight management, digestive comfort, heart health, and blood sugar control.

You’ve heard about complete proteins, and you know that beans are a great non-animal protein source, but you find yourself asking, “Are beans a complete protein?” We will provide you with that answer, as well as the specific definitions of what makes a complete protein, and whether or not so-called “complementary proteins” get the job done in providing you with all nine of the essential amino acids that keep your body growing and functioning.

What Is a Complete Protein?

When someone speaks of a “complete protein” they are referring to the amino acid content of a food. Amino acids are the building blocks of protein in the body, meaning they are involved in building muscle, repairing tissue, and so much more (like producing your much-needed hormones).

There are 20 different amino acids in the human body, nine of which are considered essential, meaning they must come from a food source because the body can’t create them in-house. A complete protein has all nine of these essential amino acids, not least because for protein synthesis and muscle creation in the body, all nine are necessary.

Examples of complete proteins are eggs, chia seeds, Greek yogurt, quinoa, and soybeans. These are all great sources of protein that are either non-meat or plant proteins, and thus are especially valuable for those keeping vegetarian diets as well as vegan diets (where it’s all the more difficult to get enough protein).

When talking about foods, complete proteins must have all nine essential amino acids in sufficient amounts. If a food is lacking in one or two amino acids, it needs to be eaten with a complementary protein to make for a complete protein meal.

What Are Complementary Protein Combinations?

When you have a food that has, say, eight out of nine essential amino acids, or you have a food with all nine but two of the amino acids are only present in trace amounts and, therefore, not enough for your body to effectively use, well… what then? Of course, it’s not as if an incomplete protein is suddenly trash food to be thrown to the wolves, so what can you do?

No worries: if a complete protein is what you’re after, then you might easily pair two foods in one dish, each of which have complementary amino acid profiles. What one food lacks, the other makes up for, and vice versa!

One of the best-known examples is hummus eaten with pita bread. The protein in whole wheat is almost complete, deficient only in the amino acid lysine. Meanwhile the protein in chickpeas does contain a significant helping of lysine, which together makes this Middle Eastern staple a complete protein snack. Combine one whole wheat pita and 2 tablespoons of hummus, and you net 7 grams of protein. Other easy combinations for complementary protein sources include a whole wheat bread and peanut butter sandwich, hemp seeds added to a dish with lentils, or non-Greek yogurt combined with almonds or sunflower seeds.

So… Are Beans A Complete Protein?

The answer is: not without rice! Most beans are high in lysine but low in the essential amino acid methionine. Whole grain rice on the other hand is low in lysine, but rather high in methionine. On top of that, rice and beans is one of the simplest and most affordable vegan meals around (for those who are only interested in plant sources of protein), and one of the easiest sources of protein you can make for dinner. In a 1-cup serving of rice and beans you can gain a complete protein content of 7 grams. This meal choice is also a great way to load back up on carbs and protein after a workout.

The Many Health Benefits of Beans

Beans are valuable not just as a source of protein for your daily protein requirements, but for many more of the nutrients your body needs. Check out the following nutrition facts about beans, and see if you don’t feel like making rice and beans a regular staple of your household.

Learn whether beans are a complete protein.

The Bean Family

Beans are seeds that come from the Fabaceae flowering plant family, and are technically classified as legumes (a member of the pea family). Other legumes are peanuts, lentils, and (of course) peas. The bean family includes the following varieties:

  • Black beans
  • Soybeans
  • Garbanzo beans
  • Pinto beans
  • Lima beans
  • Black-eyed peas
  • Kidney beans
  • Navy beans
  • Red beans

The Health Benefits of Beans

Outside of its protein and amino acid content, check out just what else beans can offer to your health and well-being with these six facts.

1. Nutrient Density

Beans are full of the vitamin folate, which is vital for pregnant women and for anyone in their early childhood or adolescence, which are periods of time when we are growing rapidly. Note here that dried beans have close to double the folate of canned beans. Though it may take an extra step in preparation, cooking your own beans from their dried form is better for you in the folate department. However, even canned beans contain more folate than so many other foods, so they’re still worthy of inclusion if they’re easier for you to work with. A lack of folate can lead to folate deficiency anemia, which can result in heart palpitations, fatigue, irritability, and loss of appetite.

Some other important nutrients in beans include zinc, iron, magnesium, and fiber, needed regularly in our diets for comfortable digestion and gut health.

2. Heart Health

Consuming beans on a regular basis shows a correlation in scientific studies to a reduced likelihood of death from stroke, heart attack, and other cardiovascular diseases. A multi-study analysis from 2013 showed a clear connection between the consumption of beans and a reduction in risk from coronary heart disease, while even more research suggests that beans have the potential to lower dangerous LDL cholesterol levels, another contributor to heart disease.

3. Antioxidant and Anti-Cancer Properties

Rich in the antioxidants known as polyphenols, which help combat the damage done by free radicals in the body, beans can help prevent certain forms of cancer according to the American Institute for Cancer Research, as well as unhealthy inflammation. There has been research showing that black beans specifically have the highest antioxidant effect, which you may want to take into consideration when you’re choosing between beans at the grocery store.

4. Glucose Metabolism and Diabetes

Because beans are high in fiber, they can help prevent diabetes and stabilize blood glucose levels. Beans are often considered a diabetes superfood, with the American Diabetes Association saying specifically that pinto, navy, kidney, and black beans are each full of important vitamins and minerals like potassium and magnesium. Soybeans are also contributors to pancreatic health, and the pancreas produces the insulin that regulates blood sugar in the human body.

5. Appetite Control

Not only do people often feel fuller after eating beans due to their starch and fiber content, which cuts down on their caloric intake each day, but these healthful aspects of beans can even help prevent food cravings in the first place. Appetite control means a greater ease at losing body weight, which is valuable for those struggling with obesity and the health concerns that accompany the condition.

6. Preventing Fatty Liver Issues

When fats accumulate in the liver, it could lead to the metabolic disorder that is fatty liver disease. Beans can contribute to the prevention of nonalcoholic fatty liver disease, another health benefit from this protein provider (even if it’s not at the golden ratio of a “complete protein”).

These Beneficial Beans: Are There Any Downsides?

The most common complaint about beans is that they can cause gas and increase intestinal discomfort as a result (beans, beans, the musical fruit…). Though it’s usually not dangerous, some may find having extra gas to be quite unpleasant. There is a way to better avoid the issue: by hot-soaking, boiling, or pressure-cooking beans, you can reduce the chance of having gas or intestinal issues as a result of your meal. This practice may also be of use to those with IBS or inflammatory bowel syndrome who may want to include the protein and nutrients of beans in their diet, but must be wary of the strong fiber content on the digestive tract.

Protein, Pro-Beans

Long story short: no, beans are not considered one of the independent sources of complete protein, but they can easily become complete when paired with whole grain rice or cornbread (which go together as well as red beans and rice in that they’re all complete proteins). When searching for complete protein foods, it’s vital not to limit yourself when complementary proteins combos are available as well. You should welcome beans into your diet not just for the sake of your health, but for the rich variety of flavors and textures that make living well both a pleasure and a joy.

When Is the Best Time to Take Protein?

The best time to take protein supplements depends on your activity level, your personal goals, and the types of workouts you engage in. This article will provide you with specific, scientifically backed recommendations, and the reasoning behind that advice.

When taking protein supplements, people often wonder when exactly is the best time of day to consume them. Pre-workout? Post-workout? Is it okay to drink a protein shake before bed? Protein supplements can help people lose weight, build muscle, and recover from tissue damage due to injury or surgery. Because they’re so effective, most people want to be sure they’re utilizing protein the right way. So when is the best time to take protein? Short answer is: that depends on your health goals and the kinds of workouts you’re doing. For the longer answer and more detail, read on.

The Different Types of Protein Supplements

Protein is a source of energy for the body, essential for muscle growth, repairing damaged tissue, and preventing certain infections and diseases. Normal dietary protein comes from foods like meats, eggs, fish, dairy, grains, legumes, and seeds. Though animal products contain the most amount of protein, vegetables are sources of protein too, a fact well-known by those living a vegetarian or vegan lifestyle. Of the most popular protein powders on the market in fact, a significant portion are plant-based.

Plant-based proteins include:

  • Soy protein containing all nine essential amino acids.
  • Rice protein, which is lower in the essential amino acid lysine.
  • Pea protein, which has lower levels of the essential amino acid methionine and nonessential amino acid cysteine.
  • Hemp protein, which is low in lysine but high in fiber, and omega-3 and omega-6 fatty acids, both of which are essential, meaning your body can’t make them on its own, and needs to gain them from the foods you eat.

Dairy-based proteins include:

  • Whey protein, which is absorbed relatively quickly and contains all nine essential amino acids.
  • Casein protein from milk curds, also containing the essential amino acids, and with a slower digestion rate than whey (which is why people often take casein before they sleep, so it will digest throughout the night… more on that timing below).

Animal-based proteins include:

  • Egg protein powder made from pure egg white protein.
  • Creatine, which is not found in plants but can be synthetically created. Though it is an animal protein, depending on its origin source, it may nevertheless be possible for vegans to use creatine as a supplement.

These are among the most commonly known protein powders available to buy, but we here at the Amino Co. have also developed an essential amino acid (EAA) blend that isn’t lacking or low on any of the amino acids required for protein synthesis and new muscle growth. It also blends free-form amino acids with whey protein and creatine, a nonessential protein that nevertheless has great value as a supplement. These forms of protein are used to help those who want to build muscle rapidly, and can even benefit those with muscle, neurological, or neuromuscular diseases.

The Varied Uses of Protein Supplementation

From muscle building to weight loss, here’s a quick look at all that supplemental protein can do to benefit your body.

Exercise Performance and Recovery

Added protein has been shown to increase endurance during training and workouts, as well as reduce soreness and speed up post-workout recovery. The timing of your protein intake matters here, whether you’re eating high-protein foods or taking supplements. Read on to learn about workout-specific timing recommendations.

Muscle Building

Muscles can only be built when you have the proper amount of amino acids for protein synthesis, and when you’re consuming more protein than your body breaks down during workouts. Taking a protein supplement, especially one that contains all the necessary EAAs for muscle growth, can make a huge difference. Finding the right anabolic window, the period of time when the protein you take in will go directly to your muscles, is something the International Society of Sports Nutrition has done extensive research on, and we, too, will provide specific scientific reasoning below.

Muscle Loss Prevention

Muscle mass is lost not only during intensive workouts, but also naturally as we age. Each decade you live after the age of 30 brings with it a higher risk of losing muscle (anywhere between 3-8% per decade). Proper protein intake is not only valuable to athletes, bodybuilders, and anyone who works out regularly, but it’s also important for each and every one of us as we age. Most Americans reserve their protein more for dinner than breakfast (3 times the amount on average is the difference between the two meals), and could use a supplemental boost of protein first thing in the morning to shore up their protein stores and help prevent the loss of muscle mass due to aging.

Fat Loss Facilitation

Protein is filling enough to help curb hunger pangs and chemically contributes to appetite suppression by reducing the “hunger hormone” ghrelin. A high-protein diet raises your metabolism and increases levels of appetite-reducing hormones like peptide YY (PYY) and glucagon-like peptide-1 (GLP-1). More satiety means fewer calories consumed throughout the day, which quickly leads to safe, maintainable weight loss and the reduction of dangerous body fat.

The Enduring Power of Protein

Popular because they’re convenient and effective, protein powders and supplements are here to stay and can offer you a wide variety of options, from self-mix formulas and powders to ready-to-drink protein shakes. If you’ve got your preferred protein supplement ready to go, then it’s time to wonder: when should you drink protein?

The Best Time to Take Protein Depending on Your Workout

Depending on your goals and activities, there are recommended times to take protein for the greatest effectiveness for your energy levels and muscle-building needs. Here are specific recommendations based on different types of workout activity.

The best time to take protein supplements.

Aerobic/Cardiovascular Exercise

Best time to take protein: Pre-workout and post-workout

The amino acid leucine is one of the three branched-chain amino acids (BCAAs), and it promotes muscle recovery after workouts. Not only that, it activates protein synthesis, prompting new muscle to be built. One might think that due to leucine’s ability to boost endurance and stamina, one should take a BCAA supplement before a workout, but the science contradicts that idea. Not only are BCAAs only three of the nine essential amino acids needed to construct new muscle, leucine and the other BCAAs (isoleucine and valine) experience oxidative degradation during aerobic activity.

BCAAs are Insufficient Pre-Workout

Adding these limited amino acids before your workout, especially in the unbalanced form of BCAAs instead of a complete EAA formula, means that a greater percentage will be oxidized and used for energy instead of muscle building. Your body does not want to be out of balance, so a sudden overabundance of a few amino acids will cause the body to clean up and reduce them in order to maintain equilibrium.

Rather than risk burning off the protein you put in because your body is only looking for energy sources, it’s better to take a full measure of EAAs within the hour after your aerobic workout, when your body is looking for supplies to rebuild. Leucine will be there to prompt muscle protein synthesis, and the rest of the essential amino acids will all be included in the ideal ratio for generating new muscle growth.

EAAs are Effective Pre- and Post-Workout

That being said, taking a complete amino acid protein supplement before an aerobic cardiovascular workout (like a high-intensity interval training or HIIT class), not only provides the necessary ingredients for muscle building, but also helps fight fatigue in a way that only taking BCAAs can’t, by fueling your body with the amino acids that help produce dopamine and serotonin in the brain.

Whether you’re walking, cycling, running stairs, or jumping rope, start by taking your EAA supplement 30 minutes before your workout session. The biggest benefit comes when you take your EAA supplement within an hour after your workout, when your blood flow is strong and active. Not only will the amino acids rush in to replace damaged muscle fibers with new muscle, EAAs can also help calm unnecessary inflammation. That will help quicken your recovery, allowing you to feel only the good side effects of working out, like increased energy and light euphoria, instead of soreness and fatigue.

Resistance Exercise

Best time to take protein: Pre-workout, during, and post-workout

Research has shown that EAAs given 30 minutes before a resistance exercise workout prompt muscle protein synthesis much more effectively than consuming EAAs afterwards does. Taking a protein supplement before this type of workout helps prevent the breakdown of muscle protein during the activity, and also increases blood flow to the muscles, thus getting the amino acids quickly into the muscle where they’re needed.

Consuming EAAs after a resistance workout is not harmful by any means, as that method, too, will prompt the stimulation of muscle protein synthesis, but it’s not ideal to leave the consumption of EAAs until after your resistance training is complete. Our recommendation is to first and foremost take a complete protein supplement before a resistance workout, and if possible take them throughout and/or after as well to get the most benefit.

Bodybuilding

Best time to take protein: Pre- and post-workout, and also before bed.

Immediately before and after a weight-lifting workout, we recommend that you take 15 grams of EAAs each. An EAA supplement has been shown to have a faster effect on muscle protein synthesis than either whey or casein protein alone. However, our Amino Co. blend of free-form EAAs with whey and creatine support ensures that you get a fast dose of EAAs and that the EAAs from whey will digest more slowly as you work out, offering a steady supply to help prevent muscle breakdown. Creatine helps prevent catabolism by supplying faster energy than your body can naturally generate from muscle cell mitochondria. This means more energy for more reps, which ultimately means more work put in and more muscle gained.

An hour after your post-workout dose of EAAs, we recommend another 15-gram dose. On off days, continue taking these same doses, measured between meals instead of surrounding your workout. Lastly, it’s also recommended you take another 15-gram dose before bed to keep your muscles fed as you sleep and to help prevent muscle breakdown as much as possible. You work hard to gain your muscles, and we encourage you to protect those gains at every opportunity. Set your alarm to take one more dose around 4 am if you know you won’t have a problem falling back to sleep, that way your muscles never go hungry for fuel.

It should be noted here that bodybuilders aren’t the only ones who benefit from taking extra protein before bed. One study of 16 elderly men showed that those who consumed casein protein (which digests slowly) before bed had increased muscle growth over those who took a placebo, despite being less active individuals. When you’re sleeping, it’s the protein that counts, and not the activity.

Is There Any Downside to Taking Protein Supplements?

The majority of scientific studies into how our bodies process high amounts of protein show that you can safely consume plenty of protein without risk of harmful side effects. Unless your doctor advises against protein supplements or you have a known kidney issue like rhabdomyolysis, there is no need to worry about excessive protein intake; merely take your products as recommended and spread them throughout your day.

Timing Is Everything

At the end of the day, it’s true that people who work out need more protein, but even those with a less active lifestyle benefit from consuming extra protein for strength, for maintaining healthy weight levels, and for preventing the loss of muscle mass we all experience as we age.

Make a protein shake for breakfast, have another to curb your appetite between meals, and make another as a beneficial treat before bed. Know that the more regularly you take in balanced forms of protein like Amino Co.’s complete EAA blend, the more good you can do for your body. Whether you’re working out or not, upping your daily protein intake is safe and smart. Bulk up, slim down, and stay strong with protein!

What are Amino Acid Functional Groups?

What is an amino acid functional group? This article will answer that question with information on amino acid classification and how proteins (and possibly all life on Earth) are formed.

What are Amino Acid Functional Groups?

So you’ve heard of amino acid functional groups and you want to understand them better. This article will help to clarify the structure of amino acids, their functional groups, and what it all has to do with the creation of protein.

Some Basic Reference Definitions

Below are the names of the 20 common amino acids in the body, nine of which are essential amino acids, meaning humans must eat or otherwise consume them to get what we need to function. The essential aminos are designated with an asterisk (*). There are their names, their three-letter codes, their one-letter codes (as used in drawing models of molecular bonds), plus their bond type and properties. Polar vs. nonpolar bond types refers to their covalent bonds. We will start with those definitions for the bond type category—get ready for some high school clique metaphors to help you visualize all this organic chemistry.

Covalent Bonds

Covalent bonds form the base of the chemical reactions between atoms of different elements. The bonds form in only one way: when an electron becomes shared by two elements. That creates the connection that then results in a new substance. Covalent bonds can exist as polar or nonpolar compounds, and all bonds that are polar or nonpolar in nature are by definition covalent.

To visualize: think of these bonds like the bonds of friendship. Two students (atoms) come close to one another and share their lunch (electrons). This sharing means there is a bond of friendship (the covalent bond). Whereas before they had been two separate elements, strangers, now a new substance has formed: a friendship.

Polar Bonds

Polar bonds are bonds where the electrons are not shared equally between two atoms. These types of bonds are what designates polar molecules from nonpolar ones. This occurs when the two atoms bonding are from two different elements; atoms from the same element do not form polar bonds.

Just as bigger planets can hold bigger moons in their orbits, so it is with atoms: they pull electrons to the best of their ability, but when they come into the orbit of a better puller (a bigger planet), that atom will pull more electrons into its orbit (and steal the lesser planet’s moons).

When two atoms of the same element meet, neither is stronger than the other, and thus neither one is more attractive than the other regarding electrons, and so neither side exhibits the polar pull, and the bond is considered nonpolar. The negative charge end of the bond is the more attractive atom, because it can draw more negative (-) electrons.

To put this back into the context of our high school friends, let’s say the two atoms meeting and bonding are a vivacious theater student and a more reserved math student. In sharing lunch, somehow the theater student always gets more to eat because the math student is so transfixed and feels the need to be overly generous. This is true whenever the theater student meets someone with less personal magnetism, which means the theater student gets an overabundance of food (electrons), which is negative because the increased calories may cause the theater student to gain weight, or get a bad complexion from eating too much processed lunch food. Eventually the theater student will fill up to the brim with extra food, and won’t be able to accept any more.

Nonpolar Bonds

A nonpolar bond is formed when two atoms from the same element meet and share electrons equally and evenly with one another. Neither atom is a better electron puller than the other, and so there is no one side more polar than the other.

In our friendship metaphor, this is a bond between two theater students, or two math students, who pool all of their lunch food together in the middle of the table, and pull from the pile equally and in unison.

Hydrophobic vs. Hydrophilic

For the properties category, hydrophobic and hydrophilic refer to molecules and their reactions to water. Molecules that repel water, or are phobic of hydration, are hydrophobic. The molecules that can form an ionic or hydrogen bond with a water molecule are hydrophilic, they have a philia for water, they like the feel of it.

If atoms are students once again, the hydrophilic ones are either on the swim team itself, or part of a group that likes to swim and heads out to the beach or the lake every weekend. The hydrophobic ones either can’t swim or simply do not like it. Hydrophobic students will tell you that their friends and the community pool go together like oil and water: they don’t mix.

It’s a lot of information, to be sure, but it’s provided as a reference point to help facilitate the following explanations.

What Are Amino Acid Functional Groups?

Amino acids are all made up of groups of atoms, and the functional groups are the important ones in each amino, it’s what makes them different and unique, deciding whether the amino overall is polar or nonpolar, acidic or basic.

Each of the above standard 20 aminos have one hydrogen atom, and two groups attached to its alpha carbon atom: an amino or amine group (~NH3+) and a carboxyl group (~COOH). They are each then distinguished from other types of amino acids by their third attached functional group: side chains referred to as R groups. When you ask what are amino acid functional groups, here they are, with the R group being the one with the most diversity. When you think of R groups, think R for radical, as it’s the variable part that makes each amino acid different from the rest.

What is the amino acid functional group?

About R Groups

Of the 20 standard amino acids that make up the building blocks of protein:

  • 6 of them have hydrocarbon R groups
  • 7 of them have neutral R groups
  • 6 of them have acid or base R groups

The simplest of the amino acids is glycine, which has just one hydrogen atom in the position of the side chain group (no R group at all, just an attached loner).

Some Quite Interesting Relevant Facts

  • In chemistry, organic compounds are generally thought of as any chemical compound that contains carbon, which includes amino acids.
  • All amino acids are soluble in an aqueous solution (water), even the hydrophobic ones (counterintuitive but true).
  • All naturally occurring amino acids are in the L-form; L for levorotatory, referring to the way you’d turn the amino acid to read the order of its attached groups (the opposite of is dextrorotatory or D-form).
  • As you can see in the above list, 50% of the amino acids have nonpolar side chains. The other half is designated polar, five of which have side chains that are not only polar, but charged.
  • Because the carboxyl group is an acid, it can form peptide bonds with the base amino groups of other amino acids, causing chemical reactions that create polypeptide chains and amino acid residues.
  • When two amino acids react and form a peptide bond, and that process goes on to be repeated, many amino acids may string together, which forms a protein structure.
  • This protein synthesis (though a little more complicated than just linking acid to base over and over again like links of a chain) is among the most fundamental of biological processes, an invaluable component of every cell. Proteins make our nails and hair, protein builds and repairs our tissues, protein is needed to make our hormones, our enzymes, and many other chemicals in the human body.
  • In 1953, Stanley Miller and Harold Urey conducted a simulation, to test a hypothesis about how life originally formed on Earth. They built a closed system that contained a heated pool of water under a mixture of gases that were thought to be present in the early atmosphere of Earth. They delivered an electric current to simulate lightning, and after a week analyzed the contents of the liquid pool. In there they discovered that several organic amino acids had spontaneously formed from inorganic raw materials. This leant support to the theory that the first life on Earth arose out of the primordial ooze through naturally occurring chemical reactions like a little flash of lightning.

Conclusion

The functional or R groups of amino acids are the groups that define the chemistry of proteins. They are the basis on which amino acids are classified, and according to the Miller-Urey experiment, possibly the start of all organic life on Earth. Not only is “What are amino acid functional groups?” a stimulating question to ask, but the answer to that question comes awfully close to revealing the true answers behind life, the universe, and…well…everything.

What Are the Best Muscle Recovery Foods?

Wondering what muscle recovery foods are good for prevention and relief of delayed onset muscle soreness? This comprehensive list of foods full of healthy fats, amino acids, and natural sugars will support your workout and recovery goals.

After starting a new workout, you’re in for some growing pains. Delayed onset muscle soreness or DOMS can affect anyone, from those new to working out to elite athletes incorporating different exercises into their routines. Whenever you push your muscles, either with unfamiliar exercises or longer durations, you’re creating microscopic tears to the muscles, which then cause stiffness, soreness, and pain. Are sore muscles a good sign? Yes, in a sense, because it means you’re using your muscles in new ways that will eventually lead to a better fitness profile. But don’t fret! Eating muscle recovery foods can help ease the discomfort and may even help decrease muscle soreness in the first place.

Using food as your method of recovery and prevention may truly be the best road to take. The other suggestions to help muscle recovery either take extra time or come with other risks, and none of them can get in front of DOMS before it starts. Getting a massage after every workout would be great, but do you have the time, the money? Rest and ice packs are perfectly reasonable options too, but it’s the rest that might bother you if you’re really excited about a new workout and seeing results. Do you really want to take a couple of days off after every workout to let your muscles recover? It might not be a bad idea, but with the right foods pre- and post-workout, it might not be necessary either.

The last refuge to treat the ache and pain of muscle soreness is to use painkillers. Whether it’s over the counter fare you’d take for any pains (a wincing headache for example, or to relieve menstrual cramps), or prescription painkillers meant for more serious pains (a wrenched back or dental surgery). And these pain killers come with health-compromising side effects that are best avoided.

So what can you eat that will make a difference? Here are some foods you might want to include on the menu on gym days.

 Muscle recovery foods for prevention and relief.

Muscle Recovery Foods

Whether for their protein content, iron content, anti-inflammatory properties, or amino acids, these foods can help your muscles heal faster.

Cottage Cheese

Cottage cheese has around 27 grams of protein per cup, and is often a regular food in the fitness community for those without any dietary restrictions surrounding milk products. In fact, the casein protein found in cottage cheese curds (as opposed to the whey protein found in watery milk) are often isolated and used as a workout protein supplement. As a slow-digesting protein, casein can help build and rebuild muscle while you sleep if it’s your last snack before bed.

The essential amino acid leucine is also present in cottage cheese, and comprises around 23% of the essential amino acids in muscle protein (the most abundant percentage of them all). Foods with leucine can help you build muscle by activating protein synthesis, and the faster you rebuild your muscle, the faster your muscle repair and workout recovery!

Eat it plain, or combine cottage cheese with some of the other recovery foods on this list to stack the benefits. Cottage cheese can even be used in baked goods and pancakes or included in protein shakes—don’t be afraid to get creative.

Sweet Potatoes

Adding sweet potatoes to your post-workout meal can help replenish your glycogen stores after a tough workout. Sweet potatoes are a great source of vitamin C and beta-carotene as well, and are loaded with fiber which helps to control appetite and maintain healthy digestion and build muscle.

Sweet potatoes can be baked whole in the oven or on a grill, cut into fries, spiced with cinnamon, or made savory with garlic powder and pepper. Enjoy them at the dinner table or on the go: a baked potato wrapped in foil can join you just about anywhere.

Baking Spices

Speaking of what you can put on sweet potatoes, it turns out some baking spices are good for post-workout recovery as well. Not so much in the form of gingerbread cookies or cinnamon rolls, but a study showed that cinnamon or ginger given to 60 trained young women (between the ages of 13 and 25) significantly reduced their muscle soreness post-exercise. If you’re already having a sweet potato, make it a little sweeter with some cinnamon, add it to oatmeal, or put some in your coffee for the extra boost.

Coffee

Did we just mention coffee? Good news: coffee’s on the list too. Research suggests that about 2 cups of caffeinated coffee can reduce post-workout pain by 48%, and another study showed that pairing caffeine with painkilling pharmaceuticals resulted in a 40% reduction of the drugs taken. If you do need pharmaceutical pain relief, maybe coffee can help you minimize just how much you take—caffeine is a much less dangerous stimulant than pain pills.

Turmeric

Another spice on the list, turmeric contains the compound curcumin, which is an anti-inflammatory and an antioxidant, and has been shown to be a proven and reliable pain reliever. Whether it’s helping you with delayed onset muscle soreness or pain from an injury (workout-related or otherwise), turmeric eases both pain and swelling by blocking chemical pain messengers and pro-inflammatory enzymes.

As with the other spices, it can be easily added to baked goods, to coffee, and to oatmeal. With its beautiful golden color, you can even make what’s called “golden milk” or a turmeric latte by combining 2 cups of warm cow’s or almond milk with 1 teaspoon of turmeric and another teaspoon of ginger, and then sip your muscle soreness away.

Oatmeal

Speaking of oatmeal (and isn’t it nice that so many of these ingredients can be easily combined?), it, too, can help relieve muscle soreness. This complex carb gives you a slow and steady release of sugar, along with iron needed to carry oxygen through your blood, and vitamin B1 (thiamin), which can reduce stress and improve alertness. This is why oatmeal is a great way to start the day, but since it also includes selenium, a mineral that protects cells from free-radical damage and lowers the potential for joint inflammation, it’s a great food for those in high-intensity workout training as well (like, up to Olympic level training).

Use oatmeal as a daily vehicle for other healthy ingredients, including the spices on this list, and enjoy its reliable benefits.

Bananas

Easily sliced into oatmeal, included in smoothies, or eaten alone, not only are bananas a healthy way to replace sweets (frozen and blended they can even make a delicious ice cream alternative), bananas are also a great way to get much-needed potassium. Research suggests potassium helps reduce muscle soreness and muscle cramps like the dreaded “Charley horse” spasm that contracts your muscle against your will and might not let up until it causes enough damage to last for days. A banana a day could keep the Charley horse away, and is particularly delicious (and helpful) when paired with its classic mate: peanut butter.

Peanut Butter

The healthy fats and protein found in nut butters like peanut or almond butter can help repair sore muscles. A reliable source of protein for muscle building, with fiber for blood pressure aid, vitamin E for antioxidant properties, and phytosterols for heart health, peanut butter offers up a ton of benefit and is easy to eat anywhere. Make a sandwich, use it to help bind together portable protein balls filled with other ingredients, add it into smoothies, or just eat it from the jar with a spoon (no one’s judging).

Nuts and Seeds

If you’re a fan of protein balls, then you’re well acquainted with nuts and seeds, which are great additions to these protein-rich foods. While providing essential omega-3 fatty acids to fight inflammation, various nuts and seeds can provide you protein for muscle protein synthesis, electrolytes for hydration, and zinc for an immune system boost. Something as simple as a baggie full of almonds, walnuts, pumpkin, and cashews can help maximize your muscles. Mixing in seeds (sunflower, chia, pumpkin) adds a healthy density that can curb your hunger and satisfy your appetite for longer. They’re small but powerful assets in quick muscle recovery.

Manuka Honey

This is not your grocery store honey in its little bear- or hive-shaped bottle. Manuka honey comes from the Manuka bush in New Zealand, with a milder flavor than that of bee honey and a much thicker texture. It’s anti-inflammatory and rich in the carbs needed to replenish glycogen stores and deliver protein to your muscles. Drizzle it over yogurt or stir it into tea to gain its benefits.

Green Tea

Green tea is particularly helpful for muscle recovery purposes. With anti-inflammatory antioxidants, it makes an excellent pre- or post-workout drink to prevent muscle damage related to exercise, and also helps you stay hydrated.

Cacao

Cacao has high levels of magnesium, antioxidants, and B-vitamins, which reduce exercise stress, balance electrolytes, and boost immunity and energy levels. The antioxidant flavanols in cacao also help up the production of nitric oxide in your body, which allows your blood vessel walls to relax, lowering blood pressure and promoting healthy blood flow. Adding cacao powder to your high-quality protein shakes or a glass of cow/almond/coconut milk post-workout will bring you its benefits.

Tart Cherries

Tart cherry juice has been shown to minimize post-run muscle pain, reduce muscle damage, and improve recovery time in professional athletes like lifters, according to the Journal of the International Society of Sports Nutrition. Enjoy tart cherry juice as a drink, or include the dried fruit as a part of your own muscle-building trail mix with the nuts and seeds discussed above. It’s not the only fruit or fruit juice you might include either. The nutrients in fruits like oranges, pineapples, and raspberries can also help speed up your recovery.

Salmon

Rich with anti-inflammatory omega-3 fats, muscle-building protein, and antioxidants, salmon is an extremely efficient post-workout food. Not an option if you are vegan or vegetarian, of course, but for the meat eaters among us, or those on the Paleo diet, salmon can specifically help prevent delayed onset muscle soreness, reduce inflammation, and provide you with an abundance of the protein needed for muscle growth. Eat this protein within 45 minutes after working out for maximum effect, either grilled, cooked up in salmon cakes, or raw in the form of sushi or sashimi. All of the above goes for tuna as well, by the way—reasons you might become a pescatarian.

Eggs

If you are an omnivore or ovo-vegetarian, eggs are great way to gain protein first thing in the morning, and an even more effective food to have immediately post-workout to help prevent DOMS. Like cottage cheese, eggs are a rich provider of leucine, and like salmon, eggs contain vitamin D (in their yolks). For your convenience, eggs can be boiled and brought along for immediate consumption after your training. Boil a dozen at the start of each week during your meal prep, and have an easy protein source in the palm of your hand every other day of the week.

Spinach

Did we really get all the way to the end of the list without a vegetable? So sorry! Let’s fix that with spinach. A powerhouse of antioxidants, not only can spinach help prevent diseases like heart disease and various cancers, but it also helps you recover quickly from intense exercise. Spinach’s nitrates help to strengthen your muscles, and its magnesium content helps maintain nerve function. Spinach helps to regulate your blood sugar (in case you worry about the spikes you might get from the sweeter items on this list), and can be added to many dinners, snuck into smoothies, or eaten on its own either raw or sautéed in olive oil.

Resist Damage and Recovery Quickly

These foods help with recovery from DOMS and reduce the amount of soreness you get in the first place by providing your body with the proteins and nutrients it craves when you’re working out to the best of your ability.

A quick note before you go. In your quest for pain-free muscles, you’ll want to avoid:

  • Refined sugar: Just one sugary soda a day can increase your inflammatory markers, as can white bread and other products with refined sugar. Natural sugars don’t bring that kind of adverse effect, so get your sugar from whole foods instead.
  • Alcohol: The dehydration caused by alcohol requires its own special recovery, and will deplete many of your vitamins (especially B vitamins). Some research suggests that alcohol can interfere with how your body breaks down lactic acid, which would increase muscle soreness. If you’re on a mission to build muscle, it’s best to avoid alcohol.

If you’re eating pretty well and avoiding what you shouldn’t eat, but still find muscle soreness a burden after working out, there is always the option to supplement.

What is the best supplement for muscle recovery? Evidence shows that getting all your body’s essential amino acids in balance will help specifically with muscle sprains and pulls, so when supplementing, just make sure you cover the waterfront (rather than choosing one or two essentials and neglecting the rest). Other than that, a diverse diet can be had in choosing natural preventions and remedies for healthy muscle recovery.

Do Avocados Have Protein?

Avocados and protein: how much protein do they contain, what else is in an avocado, and is it healthy for you? Find out!

It’s true: plant-based foods, including vegetables and fruits, contain protein. A vegetable with any more than 2 grams of protein is actually considered a high-protein vegetable, though they’ll always score lower than beans, just as beans score lower than meats. Of course, regardless of how an avocado is prepared or how green it can be, the avocado is actually a fruit, with a seed at its center. In fact, more specifically it’s classified as a single-seeded berry. So the short answer to the question, “Do avocados have protein?” is… yes! Avocados do contain protein, and to find out how much, which other fruits have protein, and how you can eat more avocados creatively, read on.

Fruits Containing Protein

The best dietary sources of protein will always be meat, followed by some beans, legumes, and dairy. For example, excellent sources of protein are chicken, turkey, fish and other seafoods, lentils, cottage cheese, and eggs. Other good sources of protein are nuts, nut butters, seeds, milk, green peas, and edamame, but it’s a sharp fall after that.

To be considered a good source of protein, a food should contain over 6 grams of protein, so none of the following fruits contains a significant amount of protein, but that doesn’t mean they don’t contain some protein for your body to use. Here are fruits high in protein, with how much content they have listed in grams per cup, from high to low.

  • Guavas: 4.2 grams of protein per cup (165 g)
  • Avocados: 4 grams of protein per avocado (201 g)
  • Apricots: 2.2 grams of protein per cup (155 g)
  • Kiwifruit: 2.1 grams of protein per cup (180 g)
  • Blackberries: 2 grams of protein per cup (144 g)
  • Oranges: 1.7 grams of protein per cup (180 g)
  • Bananas: 1.3 grams of protein per cup sliced (118 g)
  • Cantaloupe: 1.5 grams of protein per cup (177 g)
  • Raspberries: 1.5 grams of protein per cup (123 g)
  • Peaches: 1.4 grams of protein per cup (154 g)

So, while protein is easily found in animal-based foods, plant-based foods including fruits can provide it as well. Making sure there is a variety of food in your diet and establishing a balanced and healthy eating routine ensures that you’re more likely to get your daily recommended vitamins and minerals. As far as fruits, avocado is only barely beaten by guava in protein content, so it’s not to be counted out.

Do Avocados Have Protein That’s Good for You?

Avocados were originally called ahuakatl in the Aztec’s Nahuatl language, a word that meant testicle, referring to the food’s shape. American farmers in California later chose “avocado” to better market the fruit, but only after the original marketing idea of calling it an “alligator pear” didn’t catch on.

Avocados are best known for their healthy fat reputation, but are they healthy in other aspects? Well, it might be interesting to find out that avocados contain a fungicidal toxin that is not injurious or harmful to humans but is potentially poisonous to most animals. Basically, don’t feed any avocado or guacamole to horses, cows, goats, sheep, pigs, rabbits, birds, or fish.

So we humans can eat avocados, but should we, especially for its protein content?

Well, we’ve established that fruits and veggies don’t have a huge amount of protein, and so don’t work so well as a protein replacement.

However, protein does provide amino acids important for building both muscle and body tissue. Along with helping to maintain tissue health, the protein gained from avocados also serves to boost your immune system. Not only that, eating avocados helps you feel more full when you pair your avocado protein intake with other high-protein foods. You’ll appreciate increased satiety and satisfaction that curbs your appetite, which can help with weight loss if that’s your aim. With the protein in avocados, you have plenty of health benefits to gain and nothing to lose.

What Else Is in Avocados?

Besides healthy fats and protein, avocados also contain iron, zinc, potassium, and vitamin E.

Of the two types of avocados that are abundant in the United States (those being Florida and California-grown avocados), the California avocados have darker skin and are richer in taste than the bright green-skinned Florida variety, which have a milder taste. While both have the same amount of valuable fats, the Florida variety is lower in both protein and carbohydrates (which may be a plus or a minus depending on your dietary needs).

The Carbs in Avocados

The energy in avocados primarily comes from their fat content, but avocados do have a fair helping of carbs, specifically about 3 grams of carbohydrates in a 1-ounce serving of California avocados, while it’s closer to 2 grams of carbs in Florida ones. The small amount of sugar in avocados, which is a simple carb, is also slightly higher in California avocados, but nevertheless for both varieties the amount is still less than 1 gram per serving.

The Fiber from Avocados

The above carb content is largely derived from the dietary fiber that avocados have, which is another beneficial contribution from this food. Fiber keeps your digestive system working comfortably, and has been shown to help fight cardiovascular disease. One serving of either kind of avocado produced in the United States offers 2 grams of fiber, which in the body also helps to control blood sugar levels and lower cholesterol levels.

What Science Says About Avocados

The health benefits of avocados have been an area of interest for nutrition researchers. A survey published in Nutrition Journal stated that consuming avocados is associated with a better quality diet and nutrient intake, as well as lower metabolic syndrome in adults in the United States. They also advised that dietitians consider recommending avocado consumption to their patients and clients.

A study on Hass avocados (which originate from California) found that avocado oil helps promote healthy blood lipid profiles and enhances the bioavailability of the fat soluble vitamins obtained from other fruits and vegetables. Researchers highlighted that clinical studies show avocado consumption is associated with cardiovascular health, healthy aging, and proper weight management.

Avocado health benefits work on the inside and the outside. The avocado can be used as a natural cosmetic due to its rapid skin penetration and superior quality as a natural sunscreen. It turns out, the avocado is one of the healthiest things you can put in and on your body.

Ways to Include Avocado in Your Diet

Avocados feature very prominently in vegan and vegetarian diets, where any amount of extra protein is always welcome to help make up for the loss of protein gained from animal meats. If you’re only using avocados in guacamole, you are missing out on a world of new opportunities, especially if you or someone you know needs to make a new and healthier change in their diet from processed food to natural whole foods.

Its creamy texture makes it perfect for a healthy smoothie full of spinach and protein powder. You can also use avocados to make vegan ice cream, cookies, truffles, creme brûlée, or chocolate and peanut butter pudding. If you’re creating a diet that helps someone with diabetes stay off sugary snacks, avocado-based desserts could be a great way to give them a sweet treat without doing them any harm.

You could mash up a fresh avocado and use it as a spread to replace butter (it’s buttery in taste anyway!). Want to make green eggs and ham? Take that healthy avocado mash and combine it with your eggs before scrambling them, and not only do you get a fun color, but you also get a much denser, more balanced breakfast with heightened flavor and texture.

Pro Protein, Pro Avocado

Now that you know avocados are protein packed, consider all the creative ways you can make the avocado a more regular part of your diet if you want to gain all those healthy benefits. Surprise yourself and your loved ones!

Foods That Are High in Arginine

Arginine is a conditionally essential amino acid that helps support cardiovascular health, improves kidney function, and boosts the immune system. Explore its many functions, as well as which foods are good sources for arginine if you’re looking to give your body a stronger supply.

Arginine (also called L-arginine) is a conditionally essential amino acid that helps support cardiovascular health, improves kidney function, and boosts the immune system. Amino acids are the building blocks of proteins in our bodies. Essential amino acids must come from our food sources or from ingesting a supplement, but conditionally or semi-essential amino acids are on the edge. Arginine, for example, is essential during our early years of childhood growth, but is usually nonessential in normally functioning healthy adults. However, because arginine is so valuable for so many processes in the body, foods high in arginine can help shore up your stores, and may be even more important in certain medical circumstances.

This article will explore what arginine does in the human body, who could use more of it, and which foods are good sources for arginine if you’re looking to give your body a stronger supply.

Arginine: Its Role in the Body

Here are some of the health benefits that might result from an extra intake of arginine. Research is still being conducted on this amino acid and how supplementing or concentrating it might help treat certain conditions, and so far the results look promising.

Blood and Heart Health

Arginine supplements are used to treat conditions such as excessive inflammation and chronic migraines. Arginine creates nitric oxide, which relaxes our blood vessels, improves blood flow, and therefore brings cardiovascular aid for certain people and conditions. For example, those with peripheral arterial disease, angina, heart disease, and even erectile dysfunction can find benefit from increased arginine. Arginine is also associated with shortening post-surgery recovery time and helps heal injuries.

The Immune System

Studies are beginning to show arginine’s immune-boosting effects, particularly with modulating some symptoms of herpes (flare-ups) and HIV (excessive weight loss), and there have even been correlations shown between low circulating arginine and cases of trauma and cancer. Though more research is needed, it’s a valuable discovery to know that arginine is often missing when the body is experiencing traumatic events.

Kidney Functioning

Not only is arginine helpful in assisting kidney function after transplantation, but it also appears to reduce kidney inflammation. Arginine is often studied in relation to kidney functioning to try to isolate which conditions it helps best and whether or not there’s any potential harm from enhanced levels of arginine. As a natural player on the body’s chemical stage, it’s a particularly safe facet to explore.

The Research Continues

Arginine has been studied in the contexts of helping diabetes, obesity, male fertility, hypertension, dementia, and cancer, and the research goes on still. Scientists and doctors work to pinpoint the best application of arginine treatment and to better define its powers of influence. As a naturally created amino acid that helps us grow and keeps our bodies functioning, it’s a promising reserve for testing.

Foods High in Arginine

Short of supplementation, you can always get arginine from certain natural food sources. So which foods are arginine foods, and are they easy to incorporate in your diet? Short answer to that last question: yes, these arginine-rich foods will be easy to find and to eat (you’ve surely tried a few if not all of them already). As for which foods you should eat more of if you want to up your arginine content? Take a look at the list of foods below and start thinking about which ones you’d like to incorporate into your diet as well as your dietary intake.

Foods high in the amino acid arginine.

Turkey

Since arginine is derived in the body from protein, any high-protein food will help, but turkey breast in particular has such a substantial amount of arginine that it’s considered the best source around. With a high amount of omega-3 fatty acids and B vitamins to boot, one cooked turkey breast provides 16 grams of arginine.

Sunflower Seeds

Seeds and nuts have a fair amount of arginine, with sunflower and sesame seeds both contributing 2.4 grams of arginine per 100 grams of seeds. While they’re a tad low in arginine, they definitely make up in balance by providing a high amount of the essential amino acid lysine along with your arginine intake, so you don’t run the risk of overbalancing. Lysine helps absorb any excess of arginine, and will act as a check on keeping your amount of arginine within its optimal healthy levels.

Pork Loin

Another high-protein food, and with it comes another high contribution to your arginine content. Pork loin is one of the leaner cuts of pork you can get, so you’re not sacrificing one aspect of your health to favor another (balance is always key). Pork loin has 14 grams of arginine per rib, just second under the above-listed turkey breast.

Pumpkin Seeds

What did we say above about seeds, that some aren’t that impressive in the arginine department? Well, here’s an even better option then: a cup of pumpkin seeds can give you nearly 7 grams of arginine, as well as the minerals zinc and iron. Pumpkin seeds are easy to snack on and a great arginine-rich food for vegans or vegetarians who don’t eat animal products. Plus, they’re trail-mix-worthy and can be flavored sweet or salty depending on your taste.

Chicken

Chicken is a staple of a diet rich in protein and low in fat. One chicken breast can contain up to 9 grams of arginine and can be combined easily with other potent sources of vitamins and minerals like beans and vegetables in meals and stews.

Chickpeas

Another kind of chick, this time chickpeas, or as they’re also known, garbanzo beans, offer up fiber and protein (especially for those who don’t eat meat). A single cooked cup of chickpeas has at least 12 grams of fiber, over 14 grams of protein, and 1.3 grams of arginine. Enjoy it as hummus and know that it’s providing you with that little boost of arginine you’re looking for.

Peanuts

With vitamin E, vitamin B3, niacin, and folate, a cup of peanuts also gives you over 4 grams of arginine. Pine nuts, too, contain over 3 grams of arginine per cup, and a good helping of mixed nuts will almost certainly give you a fair amount of arginine, as there are levels of arginine in almonds, walnuts, cashews, Brazil nuts, hazelnuts, almonds, and pecans. Go nuts with nuts if you’re looking for foods high in arginine. Be squirrelly with them!

Soybeans

Another great protein and arginine source for non-meat eaters, soybeans and other soy products like tofu and tempeh provide potassium and magnesium. Soybeans specifically come with 4.6 grams of arginine per cup, and soybeans are also loaded with lysine for help balancing arginine.

Spirulina

Derived from a seawater blue-green algae, spirulina can be purchased in powdered form and added for its nutrients to smoothies and other foods. A cup of spirulina contains 4.6 grams of arginine, as well as iron, niacin, calcium, and potassium. You’ll probably use spirulina sparingly, but when you do know that it brings you that much more arginine along with its other nutrients.

Lentils

Another great vegetarian/vegan source of protein and fiber, arginine can be found in lentils up to 1.3 grams per cup, with lysine again to pack a double punch of amino acid intake. Lentils also pair excellently with the meats on this list for the carnivores who are interested—there’s an arginine-rich meal in the making here.

Dairy Products

Dairy products are sources of protein and thus arginine too. Just 4 ounces of cheddar cheese has a small amount of arginine, 0.25 grams, and a cup of milk has 0.2 grams, just a little bit more arginine for your effort. Some good news: if your dairy is coming in the form of ice cream, chocolate syrup has 0.9 grams of arginine per 100 grams, so add a little of it on top, or have some chocolate milk while you’re at it, and know that you’re getting some arginine there too.

Watermelon Seeds

We’ve saved the most curious for last: though most of us spit out or avoid the seeds in our watermelons, they contain over 5 grams of arginine per cup, so feel free to swallow them knowing they’re doing you no harm and also bringing you a little bit good—you can’t lose!

Arginine Foods and You

The value of gaining more arginine from foods is that it’s as natural as the healthy production of arginine within us. Not only is arginine deficiency blessedly low due to its levels in our food, but if you’re gaining a bit more of it through dietary intake, you’re not very likely to get too much of it either. With evidence showing arginine helps blood flow and heart health along with the immune response to cancer, it’s a natural amino acid to value and desire.

However: do remember that if you’re looking for even more arginine in supplement form (as with any sort of dietary supplement), it’s important not to go overboard. Too much of any one vitamin, mineral, or amino acid might have the unwanted effect of overtaxing a specific part of the body. Whether it’s by causing an excessive clean-up in the liver or kidneys, or overwhelming the other chemicals in the body that your chosen one works in concert with, you don’t want to throw yourself off kilter.

Look into well-rounded multivitamins or comprehensive essential amino acid blends that offer a measured balance of your body’s needs. Extremely high levels of arginine are no more desirable than low levels of arginine. Instead, what’s important is to have a healthy arginine ratio in the body that will meet your needs but not overwhelm your system. Eat well, supplement well, and prosper!

What Are Nonpolar Amino Acids?

What are nonpolar amino acids? This article will help explain how these amino acids are designated and what purpose they serve in the body.

Of the 20 common amino acids in the human body that build protein structures, 9 of them are essential (meaning we must eat or otherwise consume them to get them), and half of them are nonpolar. What are nonpolar amino acids? Which are they, and what does “nonpolar” mean? The review of the topic in this article will help explain.

The Definition of a Nonpolar Molecule

The nonpolar molecules we’ll be talking about are hydrophobic amino acids, meaning “water fearing” because they don’t mix with water molecules. You know how oil and water don’t mix? That’s because oil is hydrophobic.

The opposite of a nonpolar molecule is, as you might guess, polar. Polar molecules are hydrophilic, meaning “water loving.” If you’d like to visualize: polar molecules are like puppy dogs who love water so much that they’ll go barreling straight into muddy or smelly water after a tennis ball, with no hesitation at all. That would make nonpolar molecules like cats, better known for avoiding water, no thank you, and cleaning themselves without it.

Molecules are classified this way based on the charges on the atoms bonded together to form the molecule. If you remember your first taste of high school chemistry, you may remember that atoms have a nucleus of neutral neutrons and positive protons in the middle, and negative electrons swirling all around. Protons have a positive charge that draws electrons to it, like how opposites attract.

When two atoms bond together, they share electrons. Two atoms of the same element have equal positivity, so don’t have the power to steal electrons from the other. These molecules are nonpolar because they have no resulting charge. When atoms of two different elements connect together, invariably one of them will have the higher charge and attract the most electrons to its end of the joint molecule. That means the molecule is polar, or charged, and that charge will then be identified as either a positive or negative charge.

Examples of Nonpolar Molecules

Methane gas is an example of a nonpolar molecule that is created during the breakdown of food and released as a gas (or more colloquially, a fart). Methane is made up of one carbon atom that is bound to four hydrogen atoms: this hydrogen bonding allows the atoms to all share electrons equally, so this smelly molecule has no charge and is nonpolar.

Inside our body, we have both polar and nonpolar molecules, which includes those 20 amino acids mentioned above.

Nonpolar Amino Acids

The chemical properties of amino acids are largely determined by one group of molecules, what’s known as the R group: a side chain that differs on each amino acid. To visualize the amino acid groups, picture a pizza with four toppings, and a little support table in the middle that’s there to keep the cheese from sticking to the lid. That table is the alpha carbon to which all the groups or toppings are attached.

Every amino acid has three groups/toppings in common: the amino group (-NH2), the carboxyl group (COOH), and a hydrogen atom, which in pizza terms would be three standard toppings, say pepperoni, sausage, and cheese (cheese is hydrogen, which is just one atom and not a group of them, and so it gets the plainest topping). That fourth quarter of the pizza? That is the R group, the functional group that identifies and characterizes different amino acids—when you think of the R group, think R for Radical, because that is a completely different and unique topping, and every R group amino acid side chain has a distinct flavor of its own. To get up to 20 it would have to be pineapple, spinach, olives, Canadian bacon, jalapeño, garlic, anchovies, bell pepper, salami, feta cheese, beef, oregano, bacon, barbecue sauce, chicken, pesto, chorizo, broccoli, eggplant, and mushroom. Some are weirder than others.

The nonpolar amino acids have R groups mostly made up of hydrocarbons, though the amino acids methionine and cysteine also each feature a sulphur atom. The nonpolar amino acids are as follows, with more information on each one.

Glycine

  • Three letter code: gly
  • One letter code: G

The body needs glycine to make compounds like as glutathione, creatine, and collagen, which is the most abundant protein in your body. Collagen is a vital part of your muscles, blood, skin, cartilage, ligaments, and bones. Glycine may also protect your liver from alcohol damage, contribute to heart health, and improve your sleep quality. Glycine might also protect those with type 2 diabetes from muscle-wasting. You can gain more glycine by eating certain meat products or by taking a collagen supplement.

Alanine

  • Three letter code: ala
  • One letter code: A

Alanine is an amino acid that helps convert glucose into energy and helps eliminate excess toxins from your liver. Alanine keeps muscle protein from being cannibalized by the body during intense aerobic exercise or activity, and it’s needed to balance nitrogen and glucose levels in the body, which it does via the alanine cycle.

Alanine is a nonessential amino acid, which means that usually your body can make the substance on its own and doesn’t need you to ingest it from outside. However, people with eating disorders, extremely low-protein diets, diabetes, liver disease, or certain genetic conditions that cause UCDs (urea cycle disorders), may need to take a supplement or adjust their diet to gain this amino acid.

Good sources of alanine are meat, fish, poultry, eggs, and dairy products, as well as some protein-rich plant foods, like avocado. There are supplements containing alanine on the market, however, taking any one amino acid alone could upset the balance of nitrogen in the body, putting stress on the liver and kidneys as they try to eliminate waste. It is advisable that those with liver or kidney disease should consult a trusted medical professional before taking any amino acid supplement.

Proline

  • Three letter code: pro
  • One letter code: P

Proline is needed for the manufacture of cartilage and collagen, which helps heal cartilage and cushion our joints and vertebrae. It keeps joints flexible, and skin supple when it is affected by sun damage or signs of normal aging. Proline breaks down proteins for cell creation, and is essential at sites of injury where the tissue must be rebuilt to heal. Proline supplementation is sometimes valuable to people with chronic back pain or osteoarthritis.

Proline is also needed for the maintenance of muscle tissue, and is sometimes found low in long-distance runners and other serious athletes. Proline is usually nonessential, as the body naturally derives proline from its supplies of glutamic acid. However, if necessary, proline can be found in natural sources like dairy, meat, and eggs, or can be gained from amino acid supplementation.

Valine

  • Three letter code: val
  • One letter code: V

Valine is a branched-chain amino acid (BCAA) that works with the other two BCAAs (isoleucine and leucine) to regulate blood sugar, repair tissues, and provide the body with energy. Valine assists in stimulating the central nervous system and is necessary for mental functioning. Valine helps provide muscles with extra glucose energy during intense physical activity, which prevents muscle breakdown, and helps remove toxic excess nitrogen from the liver. Valine may help the liver and gallbladder recover from damage due to alcoholism or drug abuse, as well as help possibly reverse alcohol-related brain damage, or hepatic encephalopathy.

Valine is an essential amino acid, and must be obtained through a diet including meats, mushrooms, dairy products, peanuts, and/or soy protein. Most people have no problem getting enough valine, however maple syrup urine disease or MSUD is caused by an inability to metabolize leucine, isoleucine, and valine. Supplementation is sometimes warranted in those with low-protein diets or who are trying to build muscle mass, but be advised that too much valine intake will make one’s skin feel like it is crawling, and may cause hallucinations. Supplements should always be taken responsibly.

Leucine

  • Three letter code: leu
  • One letter code: L

Leucine helps with blood sugar regulation, muscle repair, and energy production. It also helps burn fat located deep inside the body that is hard to reach through diet and exercise alone.

Leucine is a branched-chain amino acid (BCAA) along with valine and isoleucine, all of which help to promote post-exercise muscle recovery, leucine being particularly effective, as it converts to glucose the fastest of the three. That is also why leucine is closely linked with the regulation of blood sugar, and why a leucine deficiency causes symptoms like hypoglycemia: headaches, fatigue, dizziness, confusion, depression, and irritability.

Leucine promotes the recovery of skin, bones, and muscle tissue after injury or surgery. Natural sources of this essential amino acid are meat, nuts, soy flour, brown rice, beans, and whole wheat.

Isoleucine

  • Three letter code: ile
  • One letter code: I

An isolated form of leucine, isoleucine is prized by bodybuilders for its ability to increase endurance, help repair muscle tissue, and encourage clotting at sites of injury. Isoleucine is broken down for energy inside muscle tissue, and helps stabilize energy levels by aiding in blood sugar regulation. An isoleucine deficiency also produces symptoms that mimic hypoglycemia.

Isoleucine is an essential amino acid, and food sources include high-protein options like nuts, peas, lentils, seeds, meat, eggs, fish, and soy protein.

Methionine

  • Three letter code: met
  • One letter code: M

An essential amino acid that helps the body process and eliminate fat, methionine contains sulfur, a substance required for the production of the body’s natural antioxidant, glutathione. The body also needs methionine to produce two other sulfur-containing amino acids, cysteine and taurine, which help the body eliminate toxins, build tissues, and promote cardiovascular health.

Methionine helps the liver process fats (lipids), preventing accumulation of too much fat in the liver, which is essential for the elimination of toxins to stay functional. Methionine is needed to make creatine, a nutrient found mainly in muscle tissue and often taken as a supplement to boost athletic performance. Methionine is also needed for collagen formation, which is then used to make skin, nails, and connective tissue. One study suggested that taking 6 grams of methionine a day can improve memory recall in AIDS patients who otherwise show a marked methionine deficiency. Methionine may also help treat symptoms of Parkinson’s disease.

Methionine is an essential amino acid, and can be gained from eating garlic, beans, seeds, eggs, fish, lentils (in lower levels), meat, onions, soybeans, and yogurt.

Tryptophan

  • Three letter code: trp
  • One letter code: W

Tryptophan is an essential amino acid that helps balance nitrogen in adults and growth in infants. It also creates niacin, which is needed to create the “happy” neurotransmitter serotonin. In this way, tryptophan helps influence relief from depression and anxiety, managing pain tolerance and increased emotional well-being. Tryptophan is also associated with promoting deeper sleep.

You can get tryptophan through certain foods or a supplement in powder form. Natural food sources include cheese, milk, fish, turkey (famously), chicken, eggs, pumpkin and sesame seeds, chocolate, as well as tofu and soy.

Phenylalanine

  • Three letter code: phe
  • One letter code: F

Phenylalanine is an essential amino acid that is needed for the functioning of the central nervous system. It has been successfully used to help control feelings of depression and chronic pain, and other diseases linked to a malfunctioning central nervous system. Especially effective for treating brain disorders, phenylalanine is able to penetrate the blood-brain barrier, and only chemicals that are able to cross that barrier can directly influence brain function.

Phenylalanine is used to make epinephrine, dopamine, and norepinephrine, neurotransmitters that control how you perceive and interact with the world around you. Phenylalanine supplementation can help you feel happier and more alert, and it also has been used to treat chronic pain and improve cognitive function. An essential amino acid, phenylalanine is normally obtained from high-protein foods like meat, fish, chicken, eggs, milk, dairy products, beans, and nuts.

Cysteine

  • Three letter code: cys
  • One letter code: C

Cysteine is an amino acid containing a sulfur atom, and is used to form healthy bones, skin, hair, and connective tissue. It is also needed to make glutathione, one of the body’s natural antioxidants that fight free-radical damage. Cysteine and glutathione work together to remove toxins from the liver, and cysteine is often used in emergency rooms to treat acetaminophen overdoses before they can cause liver damage. It also protects the brain and liver against toxins from alcohol and cigarettes, and may be useful in preventing hangovers.

Cysteine is a nonessential amino acid, which means the body manufactures it in-house, but foods such as meat, eggs, dairy products, and whole grains are also good sources of cysteine.

Nonpolar Knowledge

There you have the rundown of the amino acid nonpolar side chains, the nonpolar aminos that variously help form protein molecules in our bodies, and do so much to keep us alive and functioning at top form.
