What do essential amino acids contain? Essential amino acids for humans. Daily value of essential amino acids

Hello, dear readers of my blog! If you're serious about own health, I propose to plunge into the world of organic compounds together. Today I will talk about amino acids in food products, a table of which will be attached for convenience in the article. We’ll also talk about the required daily intake for a person.

Many of us know about these organic compounds, but not everyone can explain what they are and why they are needed. Therefore, let's start with the basics.

Amino acids are the structural chemical units that form proteins

The latter participate in absolutely everything physiological processes body. They form muscles, tendons, ligaments, organs, nails, hair and are part of bones. I note that hormones and enzymes that regulate work processes in the body are also proteins. They are unique in their structure and each of them has its own goals. Proteins are synthesized from amino acids that humans obtain from food. This suggests an interesting conclusion - it is not proteins that are the most valuable element, but amino acids.

Replaceable, conditionally irreplaceable and irreplaceable

Surprisingly, plants and microorganisms are able to independently synthesize all amino acids. But humans and animals are not subscribed to this.

Nonessential amino acids. Produced by our body independently. These include:

• glutamic acid;
• aspartic acid;
• asparagine;
• glutamine;
• ornithine;
• proline;
• alanine;
• glycine.

Conditionally essential amino acids. Our body creates them, but not in sufficient quantities. These include histidine and arginine.

Foods rich in amino acids

For the full functioning of our body, each person should know which products contain organic compounds:

• Eggs – they will give us BCAA, methionine and phenylalanine. They are absorbed with a bang, guaranteeing protein nutrition for the body.
• Dairy – provide humans with arginine, valine, lysine, phenylalanine and tryptophan.
• White meat – contains BCAA, histidine, lysine, phenylalanine and tryptophan.
• Fish – an excellent source of protein that is easily absorbed by the body. Rich in methionine, phenylalanine and BCAA.

Many people believe that protein can only be obtained from animal products. This is not true. Plant foods are also rich in it and are a source of organic compounds:

• Legumes – rich in phenylalanine, leucine, valine, methionine, tryptophan and threonine.
• Cereals – will give the body leucine, valine, histidine and isoleucine.
• Nuts and seeds – provide arginine, threonine, isoleucine, histidine and lysine.

I would like to highlight quinoa. This cereal is not as popular as the usual buckwheat and millet, but in vain.

Because per 100 grams of product there are about 14 grams of protein. Therefore, quinoa is indispensable for vegetarians and perfect for meat eaters. Let's also not forget about Orthodox posts, who prohibit eating meat, fish and dairy products several times a year.

For convenience, I suggest familiarizing yourself with the list of products in the form of a table. It's possible.

Daily intake of amino acids

We need organic compounds every day, but there are times in life when their need increases:

• while playing sports;
• during illness and recovery;
• during the period of mental and physical activity.

And, on the contrary, it happens that the need for them decreases in the case of congenital disorders that are associated with the digestibility of amino acids.

Therefore, for comfort and smooth functioning of the body, you should know the daily intake of organic compounds. According to dietary tables, it varies from 0.5 grams to 2 grams per day.

The digestibility of amino acids depends on the type of foods in which they are contained. Organic compounds from egg whites are very well absorbed.

The same can be said about cottage cheese, fish and lean white meat. The combination of products also plays a huge role here. For example, milk and buckwheat. In this case, a person receives complete protein and a process of its absorption that is comfortable for the body.

Deficiency and excess of amino acids

What signs may indicate a lack of organic compounds in the body:

• weak resistance to infections;
• deterioration of skin condition;
• delayed growth and development;
• hair loss;
• drowsiness;
• anemia.

In addition to the lack of amino acids in the body, there may be an excess of them. Its signs are as follows: disturbances in work thyroid gland, joint diseases, hypertension.

You should know that similar problems may occur if there is a lack of vitamins in the body. If normal, excess organic compounds will be neutralized.

In case of deficiency and excess of amino acids, it is very important to remember that nutrition is the determining factor here.

By choosing your diet wisely, you pave your way to health. Note that diseases such as diabetes, lack of enzymes or liver damage. They lead to a completely uncontrolled content of organic compounds in the body.

How to get amino acids

We all already understand the global role amino acids play in our lives. And they realized how important it is to control their intake into the body. But, there are situations when it is worth paying attention to them. Special attention. It's about about playing sports. Especially if we are talking about professional sports. Here, athletes often turn to additional complexes, not relying only on food.

Increase muscle mass You can use valine and leucine isoleucine. It is better to maintain energy reserves during training with the help of glycine, methionine and arginine. But all this will be useless if you do not eat foods that are rich in amino acids. This is an important component of an active and fulfilling lifestyle.

To summarize, we can say that the content of amino acids in food products can satisfy the need for them for the whole body. Not to mention professional sports when the muscles are under enormous stress and they need additional help.

Or in case of health problems. Then it is also better to supplement the diet with special complexes of organic compounds. By the way, they can be ordered online or purchased from suppliers. sports nutrition. I want you to remember what is most important - your daily diet. Enrich it with foods rich in amino acids and, accordingly, proteins. Don't just focus on dairy or meat. Prepare a variety of dishes. Do not forget that plant food will also enrich you with the necessary organic compounds. Only, unlike animal food, it will not leave a feeling of heaviness in the stomach.

I say goodbye, dear readers. Share the article on in social networks and wait for new posts.

More smart people They begin to understand that their health depends on what foods they consume, what quality of water they drink, and what daily routine they lead.

Food contains everything essential microelements for the normal functioning of the human body. Only each food group: carbohydrates, proteins, fats contains a certain set of beneficial microelements.

Now you will read which foods contain amino acids that affect height, weight and other parameters of the human body.

Nowadays amino acids “extracted” by chemical means are mass produced/sold in beautiful jars.

To understand the problem, let's give an analogy.

Previously, you regularly went to the supermarket for groceries. Every day you took a walk and carried a bag of groceries. In a word, your body “moved.” And then another person started shopping for groceries.

You have fallen out of the usual rhythm of life; your body has ceased to experience programmed, useful loads. Such a change in the rhythm of life will give a positive or negative effect? You decide.

Only when an athlete begins to consume “pure” amino acids that he bought does his body begin to “be lazy”: it stops efficiently extracting amino acids from food.

Now read which foods contain essential amino acids

Basically, amino acids are found in products of the protein group: various types meat, legumes, dairy products, nuts, wheat, oats, fish, mushrooms, seafood, eggs, some types of fruits, seeds of some plants (sunflower, pumpkin).

By eating these protein group foods, a person allows the body to independently produce the amino acids necessary for normal functioning.

For example: tryptophan is produced from bananas, oats, dried dates, pine nuts, cashews, chicken and turkey meat, milk, yogurt, cottage cheese.

Some foods containing amino acids

The amino acid “phenylalanine” is found in fish, milk, cottage cheese, chicken meat, fish, beef.

Valine is found in grains, mushrooms, peanuts, dairy products, and soybeans.

Isoleucine is produced from chicken meat, almonds, cashews, eggs, fish, lentils, rye, liver, and soy.

Leucine is found in wheat, nuts, fish, chicken, sunflower/pumpkin seeds, meat, and rye.

Lysine is found in fish, nuts, wheat, dairy products (cheese/cottage cheese), and meat.

Table of amino acid content in food

Now you can plan your diet yourself, knowing which foods contain amino acids.

Amino acids are essential organic compounds that serve to form protein molecules.
All known amino acids are conventionally divided into two types: essential and non-essential. The first (they are also called essential) are an integral part of the full functioning of the body. That is, this type It is not synthesized independently by the human body, but must be supplied only with food and absorbed into the blood in digestive tract. While the latter are created during metabolism and can be created in case of deficiency.
Essential amino acids for people are of paramount importance in their life. The lack of building blocks causes the following consequences:

Slowing down or completely stopping the growth of the body.

Weakening of the immune system.

Reduced overall weight.

Metabolic disorder.

Essential amino acids

An adult organism is characterized by the following 8 essential amino acids:

1. Valine is an amino acid with a branched chain structure. The action of valine is aimed at restoration, regeneration of damaged tissues, as well as growth. Guarantees protection against muscle tissue breakdown by providing required quantity energy. Valine is necessary for full brain function and removes nitrogen from the liver. When consumed in large quantities narcotic substances or alcoholic drinks, helps restore the affected body.

2. Leucine, like valine, restores muscle tissue. In terms of time and efficiency, it takes a leading position, turning into dextrose (glucose), which allows you to avoid metabolic breakdown during heavy training. Monitors blood sugar levels and accelerates fat burning. Increases immune resistance, takes part in the rapid regeneration of bodily injuries.
3. Isoleucine is necessary when pumping up muscles (in bodybuilding). Improves endurance during physical activity and helps quickly recover muscles. Reduces stress, utilizes cholesterol. Participates in the production of blood hemoglobin.
4. Threonine. Takes direct part in the formation of muscle tissue, connective tissue (collagen), the formation of protein, which helps tissue repair, creates bone tissue. Promotes growth and normalizes metabolic processes. Affects almost all systems: immune, central nervous, cardiovascular.
5. Methionine. Removes and processes excess fat reserves. Removes toxic substances through the formation of cysteine, glutathione and taurine. Serves to maintain the performance of the skeletal muscles. Provides proper appearance of skin, hair, nails. Accelerates lipid metabolism.

6. Tryptophan has the ability to be converted into nicotinic acid. Participates in the synthesis of serotonin and methionine. Increased content serotonin calms and improves sleep.
7. Lysine is characterized by its opposition viral infections. Thanks to it, antibodies are synthesized and, as a result, strengthen the immune system. Produces hormones that renew bone tissue and regulate growth processes. Is preventative and healing element for a cold.
8. Phenylalanine. Ensures full functioning of the central nervous system. The ability to pass through the BBB (blood-brain barrier) allows you to cope with neurological diseases. Eliminates signs of hypochondria and depression. Treats a disease associated with skin pigmentation disorders due to the lack of melanin. Promotes the manifestation of positive emotions, increased mood and deep concentration on any object. Schizophrenia and Parkinson's disease are also treated with this amino acid. It is not recommended to eat foods with high concentration amino acids for people suffering from migraines and arterial hypertension.

What to eat?

In the human body, essential amino acids are formed when certain foods are consumed. Miscellaneous Products contain different amounts of amino acids.

Essential aminocarboxylic acids are found in the following foods:
1. Valine: mushrooms, dairy products, meat, soy protein, nuts.
2. Leucine: meat, soy flour, nuts, legumes, brown rice.
3. Isoleucine: meat products, fish, soy, liver, nuts, peas, seeds, cashews, almonds.
4.Threonine: green vegetables, meat, milk, mushrooms.
5. Methionine: yogurt, meat, garlic, fish, beans, seeds, onions, soy products.
6. Tryptophan: bananas, liver, mushrooms, nuts, cheese, legumes, fatty fish, vegetables and fruits bright colors.
7. Lysine: eggs, dairy products, cheese, salmon, fish, yeast, potatoes.
8. Phenylalanine: soybeans, chicken, eggs, walnuts, beans, beef, cottage cheese.

One of the most important components of food is proteins. It is the amino acid composition that determines its value. Proteins are essential for building cells and tissues of the human body and maintaining many vital functions.

Amino acids in food

The content of essential amino acids in foods determines their biological value for the body. The biological value of proteins is also determined by the degree to which they are absorbed by the body after digestion. The degree of digestion, in turn, depends on several factors. What state is the body in, the activity of its enzymes and the depth of hydrolysis in the intestines. Also, the degree of digestion largely depends on pre-treatment protein in cooking. Grinding, chopping, boiling and heat treatment facilitate and accelerate the processes of digestion and absorption of protein, especially plant origin.

Foods rich in amino acids

Let's look at which products contain . The main source of essential amino acids is food. Proteins of animal and plant origin in mandatory must be present in a person's daily diet. The saturation of plant and animal proteins with amino acids is different, so it is necessary to ensure their correct combination. It is best to eat meat and fish with flour products, milk with cereals, eggs with potatoes.

Products with high content amino acids are necessary for humans just like air, so it is worth paying enough attention to protein foods when compiling a diet.

Amino acids in foods table

Essential amino acids in foods

Most often, there is a shortage of three amino acids in the diet, which is why products containing protein are usually assessed by the amount of their content.

So, let's look at which foods contain the amino acids methionine, tryptophan and lysine.

Methionine It is found to a greater extent in dairy products, but it is also found in acceptable quantities in fish, meat and eggs. Among the representatives of vegetable protein, legumes and buckwheat can boast of the presence of methionine.

Tryptophan found in eggs, cheese, fish, cottage cheese and meat. However, the percentage of its content in meat varies depending on the part of the carcass. IN connective tissues(neck, shank) there is very little of it, but there is more than enough in the pulp and tenderloin. Among plant foods, beans, peas and soy are rich in tryptophan.

Lysine contain all dairy products, as well as cheese, egg yolk, cottage cheese, fish, meat and legumes.

Free amino acids in foods

Free amino acids in foods are contained in in miniscule quantities. Most of them are part of those proteins that are hydrolyzed under the influence of protease enzymes in gastrointestinal tract. An amino acid molecule that is not associated with other molecules is very quickly absorbed into the blood directly from the intestines and prevents muscle destruction. This is why free amino acids are very popular, despite their high cost. Digestion is a fairly energy-intensive and lengthy process, and for quickly supplying the athlete’s body with protein, it is free amino acids that are ideally suited.
