The quantity and quality of proteins in the human body is constantly changing depending on its condition. Proteins are broken down and synthesized, participating in many life processes and influencing the general well-being of a person, on all his systems.
Proteins are natural organic high-molecular compounds reproduced by the human body from the residues of 20 amino acids. The most important properties of proteins are determined by which amino acid residues they make up, i.e. protein as an independent food product is not as valuable as the amino acids that make it up. They are divided into nonessential, which are produced in the liver, and irreplaceable. The latter are not produced by the body and can only be obtained from food.
Proteins are building blocks for cells, tissues and organs. Proteins are involved in the synthesis of enzymes, peptide hormones, hemoglobin, and are responsible for the basic metabolic and regulatory functions of the body. They are an essential element for building up muscle tissue, for example, maintaining skin elasticity.
Proteins perform protective, energetic, structural, catalytic, transport, regulatory and many other functions in the vital processes of all organisms. For example, hemoglobin, the oxygen carrier in the blood, is a complex protein. The most important hormone insulin is also a protein involved in functional control. These substances necessary for a person are involved in energy metabolism, in the processes of digestion. By forming compounds, they provide immunity to various infections, participate in the processes of assimilation of nutrients, minerals and vitamins.
Proteins are an essential food product, regardless of age and field of activity. This is especially important for people undergoing high physical activity. These elements should always be present in the diet. Proteins necessary for the normal development and functioning of the human body are composed of 9 essential amino acids. They are found in meat products, poultry and fish, as well as in milk, legumes, various grains and nuts. It turns out that the highest quality proteins necessary for the body can also be obtained by combining, for example, rice and legumes.
Interestingly, there is still no consensus about the need of the human body for dietary proteins. Eastern traditions are not encouraged to consume protein foods at all. For the use of these compounds, for example, India and Ceylon are in the last lines of the world rankings. But, nevertheless, life expectancy and the practical absence of cardiovascular diseases put these countries in a leading position.
