In this article, we describe the essential amino acids, the importance of which for the human being is distinguished by specialists, and also we will tell about the sources of receiving them.

  1. Phenylalanine

Phenylalanineis an essential amino acid. In the body, it can be converted into another amino acid – tyrosine, which, in turn, is used in the synthesis of the main neurotransmitter dopamine. Therefore, this amino acid influences mood, reduces pain, improves memory and learning ability, suppresses appetite. Phenylalanine is used in the treatment of arthritis, depression, menstruation pain, migraine, obesity.

Phenylalanine is found in: beef, chicken, fish, soybeans, eggs, cottage cheese, milk, and also is an integral part of the synthetic sweetener – aspartame (there are currently active discussions on the dangers of this sweetener).

  1. Threonine

Threonine is an essential amino acid that helps maintain normal protein metabolism in the body. It is important for the synthesis of collagen and elastin, helps the work of the liver and is involved in the metabolism of fats in combination with aspartic acid and methionine. Threonine is found in the heart, central nervous system, skeletal muscles and prevents the deposition of fats in the liver. This amino acid stimulates immunity, as it promotes the production of antibodies.

Threonine is contained in grains in very small amounts, so vegetarians often have a deficit of this amino acid. Food sources of threonine: eggs, milk, peas, beef, wheat.

  1. Tryptophan

Tryptophan is an essential amino acid, which in the human body is directly converted into serotonin, a neurotransmitter that causes mental relaxation and creates a sense of emotional well-being. People who are depressed have few serotonin and tryptophan in their blood. Their low content in the body causes depression, anxiety, insomnia, attention disorders, hyperactivity, migraines, headaches, stress. High levels of tryptophan can cause fatigue and difficulty breathing in people with asthma. Tryptophan is an excellent natural sleeping pill. It is abundant in carbohydrates, especially in bananas, as well as in vegetable oil and milk. Milk at night improves sleep due to tryptophan. In 1988, the sale of tryptophan in the form of a drug was prohibited, because cases of heart failure were recorded due to it over-consumption.

Tryptophan is contained: in oats, bananas, dried dates, peanuts, sesame seeds, pine nuts, milk, yogurt, cottage cheese, fish, chicken, turkey, meat.

  1. Valine

Valineis an essential amino acid, one of the main components of growth and synthesis of body tissues, it stimulates mental activity and coordination. Valine is essential for metabolism in muscles, recovering of damaged tissues, it can be used by muscles as an energy source. With a lack of valine, the coordination of body movements is impaired and the sensitivity of the skin to numerous stimuli increases. A lot of valine is contained in: soy and other legumes, hard cheeses, caviar, cottage cheese, nuts and seeds, meat and poultry, eggs. Significantly less – in cereals and pasta.
