    ABSTRACT: Aging is an inevitable biological feature of living organisms. Moreover, human lifespan is increasing. In last years, many studies featured a molecular basis and biological events that contribute to the progressive decline in cellular functioning at the time of senescence.The aging itself may be at the origin of various states that render this population very heterogeneous because subjects, at equivalent age, can be: in a state of good health at home, active – “fragile”, less active and at risk of diseases – ill, acute or chronic, dependent or independent. But they can also benefit from “successful aging” described for the first time by Rowe and Kahn in 1987 as an aging without disease or handicap, allowing a high level of physical activity and cognitive function and accompanied by an engagement and activities in the social life. The optimal nutrition is one of the most accessible modifiable factors to module the aging by means of targeted strategies in order to favor a successful aging. One of the first is the identification of persons at risk of nutritional diseases, either being by overcharge or by defects, and even by deficiencies such as denutrition. Because of physiological changes linked to aging itself can reach the capacities of eating and cause consequences on the nutritional state: loss of appetite, precocious satiety, and decreased taste perception. The nutrition plays a role on practically all factors of senescence. We will limit the subject to some fundamental mechanisms on which the nutritional impact is recognized: insulin resistance, oxidative stress, stabilization of the weight and the loss of the muscular mass called sarcopenia whose consequences are deleterious. Two levers for action are synergetic: the alimentation and the moderate physical exercise which improves its efficiency. Some practical means will then be proposed to equilibrate food, on the sight of the study results, that follows Euronut-Seneca, Healthy Aging: Longitudinal Study in Europe (HALE) which proposes a multi disciplinary approach to the successful aging and to its determinants in 11 European countries, by featuring the positive factors of successful aging in volunteers having reached a long longevity, in a good state of physical and psychological health… These advises are also those allowing to preserve a good cardiovascular, metabolic, and even vascular cerebral state, so a good cognitive status.Finally, to preserve the status in micronutrients, without hoping that global alimentary supplements allow compensating all deficiencies due to the aberrant alimentations, in particular restrictive. The epidemiological studies show that subjects taking the most of supplements are those having no deficits… in particular in antioxidatives, which increases the risk of limiting the necessary apoptosis of damaged cells.In conclusion: to conserve the desire to eat, a varied diet in moderation, in convivial manner each time is possible and without monotony which is deleterious for alimentation like sedentarity for physical well-being.
