I think that aging has an evolutionary explanation. The old must give way to the new so that life can adapt to changing environmental conditions. If generations did not change, there would be no evolution. Animals would not have formed from plants, animals would not have come out onto land and would not have given birth to humans.

Aging is the process when a cell stops dividing (stops or disrupts the synthesis of protein required for metabolism). A "signal peptide" called a peptide bioregulator is responsible for the process of starting protein synthesis and cell division. In other words, proteins "dying" constantly reproduce active molecules that give the command to synthesize new proteins and non-protein structures necessary for the life of the cell. Violation of this process leads to the cessation of new cell division, which is the biological cause of the aging of the body .

Peptide bioregulators were discovered in the 60s, Soviet (and now Russian) scientists - V.Kh. Khavinson. As the discoverer of peptides says:

"We have not created anything new, we just learned how it happens in nature and learned how to make up for the deficiency of these molecules, which means we learned to" help the body live properly. "

Currently, the molecular-genetic theory of aging is gaining popularity in scientific circles. Its essence is that a person has two types of cells: somatic and reproductive. Somatic cells transmit genetic information and divide until the body thinks that their function is not fulfilled. As soon as the body has transmitted information to its population, somatic cells stop dividing and die off. In other words, biological life depends on the duration of the body's reproductive function.

Proteins in the human body play an important role: from the creation and regeneration of tissues to the effect on the hormonal system and hormones in general. The proteins themselves, in turn, consist of amino acids, and it is them that he uses to build the protein bodies that are needed at the moment.

Almost all amino acids are of two types - L- and D-amino acids. They differ in the direction of the chain clockwise and counterclockwise. L-left-handed chain and D-right-handed chain.

It is noteworthy that the body uses exclusively L-amino acids to build protein and never uses D. At the same time, D-amino acids can be found in already created protein chains. A contradiction at first glance. Where do they come from there if only L-amino acids are used.

As scientists have found, this is due to the aging mechanism of proteins. Over time, the structure changes and D-amino acids appear in it. Because of this, sometimes even the function of the protein can change. Many have noticed that with age, the skin becomes less elastic, covered with folds and roughness. The joints stop working well and begin to bend with a creak, crunch (crunching in any joints except the knee is an unhealthy sign). This is associated precisely with the aging of proteins responsible for the specific functions of individual tissues. And this applies to the whole organism.

I also want to note that with the deficiency of individual amino acids and proteins, the body is forced to use the available resources from other tissues that are less necessary at the moment. It breaks them down to amino acids and builds up the missing proteins. It is very important to give the body a full set of amino acids to avoid this process, because in the long term this will only lead to degradation of the body. In addition, our body spends more energy on this process. Indeed, instead of building proteins from ready-made amino acids, he is forced to first decompose the old and only then synthesize new ones.

How to replenish this balance? There is a short answer - there is a sports supplement protein. There are many types of them, we are interested in hydrolysates. In particular, egg hydrolyzate. Eggs completely remove moisture from the protein and purify them, as a result, a protein is obtained that is almost 100% composed of L-amino acids, which the body uses for synthesis at no extra cost.

A more complex answer is a balanced and sufficient diet with the highest possible intake of animal and plant proteins. With such a diet, the body does not need to perform unnecessary actions for restructuring and it takes what is ready.

We are gradually approaching the possibility of influencing, at least partially, on maintaining its body in a younger state. Complete nutrition where possible and supplementation with third-party sources, whether it be sports nutrition or dietary supplements.

There is currently no consensus among scientists about a single cause of aging. There seem to be many mechanisms operating in parallel. These are telomere shortening (and stopping cell division), oxidative stress (and damage to proteins and DNA), the activity of mobile DNA elements and hyperstimulation of cell function.
