[Characteristics of nutrition in persons of older age groups in areas with different patterns of longevity]

The study of actual nutrition in old-aged subjects (60-74, 75-89 and 90 years and older) in the regions with varying levels of long-living has revealed different types of nutrition depending on the climatic and geographical zones. The character of nutrition of old-aged in varying regions permits a suggestion on the relation of long-living with low energy requirements that are formed under the influence of ecological conditions (high temperature and humidity of the air in Abkhazia) and determined genetically (Azerbaijan, Ukraine). Alteration of nutrition type according to the environmental requirements (as adaptation to high temperature), decreased energy value of food approaching the nutrition type of the indigenous population (for example, the Azerbaijans and Russians living in Azerbaijan) do not ensure long-living.
