Part 1: Eating Insects for Your Daily Amino Acids?

Pull up a chair and have a plate of bugs for breakfast?! Although this is not unrealistic or uncommon in most of the world, entomophagy (eating insects for food) brings a feeling of disgust for many in western societies, and a sourpuss face along with it! But eating insects is common to animals (insectivores), even other insects, as well as humans, and for good reasons.

Eating insects of many kinds brings to light the simple fact that they are full of protein and nutrition, and help sustain life. Vitamins, minerals, monounsaturated and polyunsaturated fats, oleic acid, and amino acids are only part of the full story.

In fact, bugs may wind up being a part of the human diet in the future, as it is currently in many countries, and has been prehistorically commonplace for hominids, hominins (human line), throughout time.

The big questions about eating insects include…

What amino acids are present in bugs and are they available to the human body? Exactly what nutritional content is covered for human requirements by consuming edible insects? Eating insects may be good for you, but do they taste good?

According to my daughter, who went to Peru with my mom and some friends and ate a large white grub that is a common to the area for consumption, it tasted lovely, just like an almond. She said, “It tasted good!” However, she also nearly gagged and spit it out. Why? The texture was “too mushy,” she said. The last thing she was thinking about was the amino acid content of the grub! *smiles*

Eating insects raw, such as her raw grub from Peru, are not always necessary. Most people around the world eat them raw as well as roasted, baked, smoked, fried, boiled in salted water, and dried or sun-dried. Of course, most Americans have heard of chocolate covered ants or grasshoppers as a delicacy dessert (or given as a joke, although is a serious meal in other countries). Each method of preparation makes eating insects a different experience, taste, texture, and can be the difference between it tasting good or wanting to spit it out on the ground from whence it came.

Who wants to eat bugs anyway? Lots of people, especially considering they are as easy to scavenge as they are to grow and raise for food, and is easier than gardening or raising small livestock. It is also cheaper than buying food at the grocery store, although bugs-on-a-stick (or loose) of many varieties can be purchased at local markets in many countries, like is often seen in China or Thailand.

The fact is that many grubs, larvae, grasshoppers, caterpillars, termites, palm weevils, mealworms, and other bugs are packed with nutrition such as potassium, calcium, sodium, magnesium, phosphorous, zinc, manganese, and copper according to the FAO. Eating insects can also supply you with necessary iron and amino acids like lysine, things that vegans and vegetarians are often deficient in.

L-tyrosine for Treating Depression Symptoms

Alleviating depression can sometimes be daunting, even with pharmaceutical antidepressants prescribed by your doctor. But there are some natural things you can do to help with depression, too, says researchers. Tyrosine, also known as L-tyrosine, is a viable option as a natural-source antidepressant.

In fact, amino acids help play a role in many diseases, and can be used as a tool to predict such diseases since the biological compounds involved in the normal functioning of humans can be involved in the pathogenesis of these same diseases.

W Krzysciak at the Department of Medical Diagnostics at the Jagiellonian University in Poland, talks about aromatic amino acids like tyrosine, and that some of the diseases that are tied to amino acids include the diagnosing and treating of “social disorders, such as cancers; psychiatric disorders: depression, anxiety states, schizophrenia, bipolar affective disorders; neurodegenerative, and cardiovascular diseases; chronic kidney insufficiency or diabetes.”

L-Tyrosine for Depression

There are three aromatic amino acids commonly used to treat or diagnose disorders: tyrosine, tryptophan, and phenylalanine. Where phenylalanine is a pain reliever, and tryptophan promotes sleep, it is tyrosine that acts as an antidepressant.

Dr. Greene (at DC Nutrition) also has information about L-tyrosine, and explains how this aromatic amino acid works to treat depression, saying, “Tyrosine is an essential amino acid that readily passes the blood-brain barrier. Once in the brain, it is a precursor for the neurotransmitters dopamine, norepinephrine and epinephrine, better known as adrenalin. These neurotransmitters are an important part of the body’s sympathetic nervous system.”

L-tyrosine also relieves pain—both emotional pain and physical pain.

Dr. Greene says, “Tyrosine therapy is very useful in a variety of clinical situations. … An average human dose equivalent of 500 mg of tyrosine given intravenously reduces susceptibility to life-threatening ventricular fibrillation in experimental animals. More tyrosine is needed under stress, and tyrosine supplements prevent the stress-induced depletion of norepinephrine and can cure biochemical depression.” The exceptions would include psychosis (since antipsychotic drugs work by inhibiting L-tyrosine metabolism).

Larger doses of L-tyrosine may help reduce hunger as well as alleviate depression symptoms in obese patients. Low doses actually stimulate the appetite, however.

Dr. Greene says that even physicians at Harvard Medical School have used between 1-6 grams of tyrosine to effectively treat depression that was medication-resistant, saying, “The minimum daily requirement for adults of tyrosine and its precursor, phenylalanine, is 16 mg/kg a day or about 1000 mg total. Hence, 6 g is at least six times the minimum daily requirement.”

Please have a discussion with your doctor or naturopath to see if L-tyrosine might be able to help with depression.

Amino Acids for Pregnancy Health

Being a mom does not just happen when you birth a new baby into the world, it starts with pregnancy. A healthy pregnancy means you need proper nutrition, such as vitamins, minerals, as well as things like folic acid, and even amino acids. There are common 22 amino acids that are important for health, and that bring with them their own respective health benefits, but some of these include alanine, tryptophan, tyrosine, cysteine, and even phenylalanine.

It is important for a pregnant mother-to-be to know that amino acids are the building blocks of protein, so this is important for the baby’s development. Proteins like muscles, organs, tissues, plus even the fetal brain, are all dependent upon the proper amount of amino acids in the mother’s body.

There are essential amino acids and non-essential amino acids. “Essential” means that they must be gotten through diet, while non-essential means that the body makes these aminos on its own. Protein foods like meats (chicken, beef, turkey, pork, etc.), plus fish and eggs, provide all 22 amino acids.

If a mother lacks enough amino acids then the developing fetus could suffer. Preeclampsia as well as spina bifida are associated with a lack of amino acids in a pregnant mom.

Lack of amino acids associated with preeclampsia and spina bifida

A study discovered that the amino acid L-arginine (also known simply as arginine) may protect against preeclampsia in pregnant women. About 5-8% of all pregnant women in the United States get preeclampsia, which shows protein levels in urine and can cause dangerously high blood pressure. If not treated it can cause low birth weight, preterm labor, or even death. Around the world 76,000-500,000 infants die because of preeclampsia in pregnancy and hypertension disorders. L-arginine amino acid helps alleviate the conditions associated with preeclampsia. Ask your doctor about how much to take.

In another study the amniotic fluid was tested to check concentrations of amino acids in pregnant women whose babies were already known to have spina bifida. Researchers said that their levels of “alanine, cystathionine, cysteine, phenylalanine, tryptophane, and tyrosine amino acids” were lower than the healthy fetuses from the control group. This suggested that the “loss of amino acids from the fetus through the spinal cord may contribute to the etiology of spina bifida.” Spina bifida, a congenital disorder affecting the spine of the fetus, can come from a lack of the mother having enough folic acid in very early pregnancy. Taking folic acid before conception is essential, as well as afterwards in order to decrease chances for the disorder up to 70%.

Be sure to get enough amino acids in your diet during pregnancy, which means not too much and not too little. This is especially important if you are vegan or vegetarian since most complete amino acids come from animals or animal products. You may want to discuss this with your physician.

Improve Sleep for Insomnia via Amino Acids and Deep Breathing

1… 2… 3… 4… How many of us have tried counting sheep, or other things that never seem to work, just to get some sleep at night? Insomnia can strike a person for a good many reasons, including: worry or fretting, stress or anxiety, racing thoughts, sleep cycles being off kilter (light therapy can sometimes help), hormones or metabolic reasons, and even due to being overly tired, among other things. However, there are two natural things you can do to help you sleep… take certain amino acids, and perform certain breathing exercises.

Studies have shown that increasing oxygen levels through deep breathing exercises, contrary to popular belief, can actually help induce sleep rather than wake you up. This is due to the connection with CO2 (carbon dioxide) levels in the body, which I will go into later.

Interestingly, amino acids can also help relieve insomnia. Two of the common 22 amino acids, in particular, are able help calm the mind and induce rest in a weary but aggravated body.

Insomniacs need oxygen, and amino acids for serotonin

Adults with insomnia were studied and given relaxation techniques, including deep breathing exercises (do not forget about bedtime yoga!) as part of information included in complementary and alternative medicine or naturopathic medicine techniques. These insomniacs, after being informed of these easy activities at bedtime, had higher rates of continued use.

Deep breathing exercises aside, it is not just increasing oxygen levels alone that help you relax and slumber, but reducing CO2 levels in the body. Amino acids actually play a vital role in this process.

In a fascinating cross-species study that compared plants, insects, animals, and humans, the levels of CO2 and anxiety were investigated. Anyone who has woken up in the night due to a panic attack knows what I am speaking about here. CO2 levels are higher in correspondence with anxiety or negative emotions.

There is a neurological ‘fear circuit’ that is not entirely understood, but evidence reviewed on the amino acid GABA (gamma-amino butyric acid) may help modulate anxiety that is CO2 induced. That is, if you take the GABA amino acid, it could help calm the mind, anxiety, and troubling thoughts so you can sleep.

Another amino acid that is known to be a natural sedative is tryptophan (like what makes you tired from turkey meat), plus serotonin (the feel-good neurotransmitter) and melatonin also help you induce sleep.

GABA and tryptophan are commonly available as supplements at health food stores and drug stores as a sleep aid. So breathe deeply and reduce the amount of CO2 in your body, plus take amino acid GABA and/or tryptophan to complement this for a good night’s rest.

Anorexia Patients’ Serotonin Levels Helped by Amino Acid Tryptophan

Serotonin is the feel-good chemical that the human brain produces in the body. People with higher serotonin levels generally are more resistant to depression, anxiety, and other negative emotions. People with adequate levels of serotonin also feel better about life, themselves, and their place in the world. Anorexic patients, suffering from the eating disorder called Anorexia nervosa, have mental and emotional as well as physical issues surrounding this disorder, and consequently can have too-low serotonin levels. Raising serotonin can be done by natural means, such as taking the amino acid L-tryptophan. Tryptophan is a neurotransmitter in the brain, which can help raise serotonin levels.

 Tryptophan is used by the body and produces serotonin in the brain, which is severely lacking in those with anorexia. This eating disorder is associated with an obsession of being overweight, so they eat very little, and sometimes nothing at all, which leads to emaciation. Body image issues are at the forefront, self-worth is low, causing a spiraling effect since anorexics think they are too fat even if they are skin and bones. Very low food intake (and therefore low in tryptophan) depletes the serotonin in the brain, since it is tryptophan dependent.

Tryptophan is an amino acid that comes from protein foods, like meats (chicken, beef, pork, lamb, etc.), as well as fish and eggs. A diet deficient in meats is also deficient in not just tryptophan, but also the rest of the common 22 amino acids that make a body healthy and resistant to disease and other health issues.

Study using tryptophan for serotonin levels in anorexic patients

A study by DJ Haleem from the Neuroscience Research Laboratory at the University of Karachi in Pakistan was done regarding anorexia patients and tryptophan. Haleem said “Patients with anorexia nervosa (AN) show extreme dieting weight loss, hyperactivity, depression/anxiety, self-control, and behavioral impulsivity. Tryptophan, the precursor of serotonin and an essential amino acid, is only available in the diet. It is therefore likely that excessive diet restriction and malnutrition decrease brain serotonin stores.”

When serotonin is low, then the availability of tryptophan “decreases serotonin neurotransmission at postsynaptic sites, leading to hyperactivity, depression, and behavioral impulsivity,” said Haleem. He suggested that tryptophan “supplementation may improve pharmacotherapy in AN.”

The effectiveness of tryptophan on serotonin levels for anorexia has not yet been evaluated, but the fact that higher serotonin levels make us feel better is well documented. Tryptophan is an amino acid that is easily bought over the counter at health food stores for supplementing the diet.

Help COPD with Amino Acids for Lung Disease

According to some researchers and there are a few amino acids for lung disease that exist and may help such issues. COPD (chronic obstructive pulmonary disease) is one of these lung conditions may be aided by amino acid supplements; in particular, those with even severe COPD. This lung disease affects the ability to breath and also reduces energy levels in those who have it. COPD may have different causes, but it can be a result of smoking cigarettes long term, as well as conditions such as emphysema. 

According to one study by RW Dal Negro, A Testa, et al., in Italy it was amino acids for lung disease that helped the patients with COPD. By supplementing COPD patients with certain essential amino acids they were able to determine if pulmonary rehabilitation might have improved health status and produce higher rates of physical performance.

Essential amino acids are several of the 22 commonly known amino acids. “Essential” means that they have to be gotten through diet since the body cannot produce them on its own. The list of essential amino acids may include: Valine, Threonine, Methionine, Leucine, Isoleucine, Phenylalanine, Tryptophan, Lysine, and Histidine.

Amino acids for lung disease – chronic COPD

A total of 88 COPD out-patients who had a 23 BMI (body mass index) or less were selected randomly to receive essential amino acids for lung disease (COPD) for a period of three months. After 12 weeks of the test period the patients receiving amino acids for lung disease had showed significant improvements in physical performance.

Also, the COPD patients scored higher on the SGRQ score (which measures breathing). Additionally, other areas were affected positively, as compared to the placebo group, who had taken the essential amino acids for lung disease (COPD), including improvements in: fat-free mass, serum albumin, increased muscle strength, oxygen saturation, and cognitive dysfunction.

The results produced greater confidence levels in the patients and the researchers for improvements in these symptoms that COPD usually negatively affects its patients. Essential amino acids may, then, help reduce symptoms of COPD, so it is clear that amino acids for lung disease can aid the patient in breathing easier as well as help their physical performance in a number of areas.

Nutrition and Depression: Amino Acids Can Improve Mood

We all know the importance of eating well. The link between an unhealthy diet and obesity, heart disease, and diabetes has led to bookshelves groaning with diet and nutrition books. But nutrition also affects our mental wellbeing. Are we getting enough amino acids to maintain our mental health?

A good diet is our best weapon in the war on disease. A healthy, well-balanced diet will also help our immune systems if we do become ill. This healthy diet will help combat some mental illnesses, too.

T. S. Sathyanarayana Rao, M. R. Asha, et al, explained the link between nutrition and depression in an article in the Indian Journal of Psychiatry. They found that the diets of many people suffering from mental disorders are deficient in essential vitamins, minerals, and omega-3 fatty acids.

Supplements containing amino acids have been found to reduce symptoms of depression. Some amino acids control our moods—they cross the blood-brain barrier, carrying the chemical signals in our brains. But if we are not getting the right amount, our moods are affected.

Amino acid supplements treat mood disorders

The major symptoms of depression include increased sadness and anxiety, loss of appetite, and loss of interest in pleasurable activities. Deficiencies in neurotransmitters like serotonin, dopamine, noradrenaline, and the amino acid GABA are often present patients with depression.

The amino acids tryptophan, tyrosine, phenylalanine, and methionine are often helpful in treating mood disorders. Indeed, tryptophan is converted to serotonin–the chemical which controls happiness.

Tryptophan is an essential amino acid, which means we must get it from our food. But people with poor diets do not get enough tryptophan.

Antidepressants and other drugs are very successful at treating depression. The researchers hope that nutritional supplements containing amino acids will work with these drugs, possibly leading to lower doses, and fewer side effects. They suggest daily supplements of amino acids to help achieve an antidepressant effect.

Nutritional neuroscience gives us our best shot of preventing and treating some mental illnesses.

Tryptophan In Antidepressants to Cure Major Depressive Disorder?

Dr. AA Badway, from Cardiff Metropolitan University (Wales, UK), published an article which points to the essential amino acid tryptophan as a possible key to developing new antidepressant serotonin-boosting drugs to treat Major Depressive Disorder.

The article, published in July 2013, focused on Major Depressive Disorder, which is also known as clinical depression, unipolar depression, or recurrent depression. This mental disorder causes pervasive, persistent low moods, where the patient can no longer experience pleasure in normally enjoyable activities. It is usually also accompanied by low self-esteem.

Major Depressive Disorder is an extremely debilitating condition which greatly impacts quality of life. Major Depressive Disorder affects private and work life, impacting eating habits, sleeping habits, and general overall health. In some cases, the disorder has led to suicide.

Serotonin deficiency is one of the causes of Major Depressive Disorder. Serotonin is a neurotransmitter, a chemical messenger that transmits signals between the brain and the body. Serotonin has many effects, including the regulation of moods.

Treatment for Major Depressive Disorder includes antidepressant medications which cause the synthesis of serotonin, and thus these medications have a mood stabilizing effect.

Serotonin is synthesized in the body by the amino acid tryptophan.

Tryptophan’s role in serotonin synthesis

Tryptophan is one of the essential amino acids, which means we must obtain it from our food. Tryptophan is widely available in most proteins, like eggs, fish, meat, soybeans, and sesame seeds.

There are several factors which cause decreased levels of tryptophan, and which result in the serotonin deficiencies which could cause Major Depressive Disorder. One factor, accelerated degradation of tryptophan in the liver, is one of the factors which must be addressed when developing new antidepressants.

The article concluded that enhancing the availability of tryptophan to the brain will result in normalized levels of serotonin synthesis, and could form the basis for new antidepressant drugs.

Does L-tryptophan Affect Women More Than Men?

An interesting study from Europe has found that depletion of the amino acid L-tryptophan affects emotional processing, specifically how we recognize fear. But are women affected more than men?

L-tryptophan is an essential amino acid, which means we must obtain it from our diet, or in supplements. L-tryptophan found in many animal and plant proteins. It has numerous functions, and has been the subject of several clinical studies for its role as producing the crucial neurotransmitter serotonin.

Serotonin is primarily found in the central nervous system, where it performs important functions. Serotonin affects memory, learning, and emotional response.

Serotonin levels are directly related to L-tryptophan intake. This means lack of L-tryptophan results in low serotonin levels, which could lead to insomnia, anxiety, and depression. Low levels of serotonin also affect mood.

L-tryptophan depletion: fear recognition different in men and women

Researchers (C Harmer, R Rogers, et al) from the University Department of Psychiatry, Warneford Hospital, Oxford, UK, selected healthy male and female volunteers to examine their responses to emotional expression, particularly fear, if their serotonin levels were low.

In this double-blind trial, the volunteers were randomly given either an amino acid drink specifically lacking in L-tryptophan, or a control drink containing a balanced mixture of amino acids. The acute L-tryptophan depletion reduced their serotonin functions.

The volunteers were given a facial expression recognition test five hours after the drink was administered. Six basic emotions were used: fear, anger, disgust, surprise, sadness, and happiness.

Results were interesting, with a distinct difference between male and female response for fear recognition only.

L-tryptophan depletion significantly impaired the women’s ability to recognize fear as a facial expression. The male volunteers were not affected, and recognized fear even if their serotonin levels were low.

Recognition of all the other basic emotions was comparable in the two groups.

The researchers concluded that acute L-tryptophan depletion does affect emotional response, and that this effect is greater in women, compared to men.

Amino Acid Supplements for Addiction Recovery

Amino acids are the building blocks of proteins, and so they come from protein foods; however, some people do not produce or assimilate amino acids as well as others, and so amino acid supplements can be utilized, especially in cases where addiction is an issue. Addiction recovery is commonly found in products that are taken internally in some way (consumption, inhalation, etc.). Amino acid supplements may help.

Food, drugs, and alcohol, are common addictions in society today. The “white foods” like sugar, white flour, white rice, and white potatoes, can act as addictive foods to someone who is prediabetic or diabetic, similarly to how alcohol or marijuana, caffeine, speed, or cocaine, can act as an addiction to someone else.

Amino acid supplements can help curb these appetites for unhealthy habits, and aid in bringing back a sense of control because they activate the neurotransmitters in the brain that affect these issues.

Amino acid supplements for addictions

Consider these addictions:

FOODS/DRINKS: Sweets, starches, chocolate, caffeine, aspartame, alcohol, etc.

DRUGS: Heroin, alcohol, marijuana, tobacco, speed, cocaine, ecstasy, valium, etc.

These items may be as much of an emotional addiction as they can be a physical addiction, depending. Be sure to ask your physician before trying to treat addictions or go through addiction recovery by supplementing with amino acids.

Amino acid supplements chart for addiction recovery

Treating or reducing symptoms to help smooth out the process of recovery may be aided by taking essential or non-essential amino acid supplements.

Here is a chart showing amino acid supplements for addictions from the Addiction Recovery Guide folks, reprinted from: Blum K, Ross J, Reuben C, Gastelu D, Miller DK.  “Nutritional Gene Therapy: Natural Healing in Recovery.  Counselor Magazine, January/February, 2001
