[Nutrition, aging, old age].
In humans there is evidence that the restriction of total caloric intake appears to be more important than the restriction of any particular macronutrient. Today the mechanism of the effect of caloric restriction is unknown. With advancing age and the occurrence of concomitant illness there is an increased risk of developing nutritional deficiencies. Altered nutritional status is associated with the pathogenesis of a number of common diseases of the elderly, thus it would appear that nutritional modulation and manipulation represents one possible approach to successful aging and a healthy longevity. The conceptual framework of the paper suggests the need of a newer light of the aging processes namely by a holistic human-gero-ecological model and a personality oriented geriatry. There are accentuated the role of the nutrients and vitamins, the food intake and drug-nutrients interactions and the meanings of the differences between the normal and pathological aging.
