Large social transformation that occurred in the USSR since the Great October revolution, the growth of welfare of workers in our country, successful implementation of the decisions of the Communist party, aimed at improvement of living conditions, a broad, public provision of population with medical care - all this, undoubtedly contributed to a significant increase in the length of life of a Soviet man. Demographic shifts caused a marked increase in the age structure of the population of the Soviet Union the percentage of older, old people and long-lived. In the modern age classification persons aged 60-74 years are elderly, 75-90 years - old, older than 90 - long-livers. The average life expectancy is currently in the USSR reached 72 years, and this is certainly not the limit. Our country is the country with the highest longevity, and the Transcaucasian Republic center of longevity, where more than 5000 persons who turned 100 years old. The process of lengthening life continues, which naturally entails the increase among our population numbers of the elderly. But the main purpose of a socialist society is not only a longer life, but also an increase in active, creative period of his life, health, vivacity, disability to old age. On the possibility of achieving this goal is said numerous examples of long-livers, which in old age (even older than 80 years enjoyed good health and considerable physical and creative activity. So, the famous Russian writer L. N. Tolstoy, academician I. P. Pavlov, artists I. E. Repin and I. K. Aivazovsky, many centenarians Georgia and Abkhazia and in old age were physically and creatively active.

Ageing is a natural biological process, genetically caused by the program of development of the individual. According to I. Century Davydov, "old age, as the coming night is early and late". Save eternal youth no miraculous means impossible, but delay old age, decrepitude, prevent the onset of premature old age - the problem is solvable, regardless of her genetic conditioning, it is necessary to consider influence of the external environment, which can be negative or beneficial.
To slow down the aging process can, in the words of academician A. A. Bogomolets ' reasonable control of their lives", i.e., observing the correct way of life: it is feasible labor activity, mode of work and rest, adequate physical activity, the rejection of bad habits - Smoking, alcohol use, and so on, an Indispensable condition of longevity, health, disability, cheerfulness is proper nutrition. Nutrition is one of the main permanently acting factors of the external environment, providing a very significant impact on human health. According to the academician of the AMS of the USSR D. F. Chebotarev, "the power is almost the only means of prolonging the species life span by 25-40%".
Since ancient times people paid much attention to food, its useful and harmful properties. The first idea about the dietetics are found already among the doctors of Greece and Rome, who lived in the II-III century BC,Hippocrates, Galen, Asclepiades. In particular, the Hippocratic belong words: "When food is introduced too heavily against nature, it causes disease." Asclepiades believed that the very nature heals, and that is correct, healthy food can better help the patient than drugs.
Scientist-encyclopedist Avicenna in the "Canon of medical science", written in 1020, gives advice on nutrition of children, the elderly, and tips for dietetics, depending on climate and health. In particular, persons advanced in years", he advises to decrease the amount of food.
These observations not only has not lost its importance at the present time, but also find the scientific evidence, further development in the modern science of nutrition.
Under the power meant the entire complex transformations of nutrients in the process of vital activity of an organism, and the act of chewing, swallowing and digesting the food is only the first stage of its assimilation. So for scientific substantiation of certain recommendations need to be aware of the characteristics of the course of metabolic processes in the body, as food is a powerful stimulant and a regulator of metabolism. Nutritional science is a system of knowledge about the transformation of nutrients in the body into energy and building material for all organs and tissues needed for growth and constant updating of cells and structures of the body; it is the science of nutrient requirements separate groups of the population, ensuring the normal course of life processes, preservation of health and life expectancy; and the establishment of diets for different groups of patients.
A very important part of nutrition science is the doctrine of food, covering the chemical composition of various food products, food and biological value.
It is known that the food gets all the necessary nutrients and elements that comprise the fabric and structure of his body, formed the energy required for human life, to exercise, to maintain a certain temperature of the body and so on
