Aspects of nutrition in the elderly.

Malnutrition in the elderly is inseparably linked to disease, immobility and social isolation. Although in percentage terms the numbers of malnourished elderly may be small, in hospital practice clinically important malnutrition is more widespread. Prevention of malnutrition is not simply a matter of distributing vitamin supplements to the elderly in the community-consideration must be given to alleviation of many of the adverse environmental conditions affecting older people. The role of dietary manipulations in the prevention and treatment of chronic degenerative disorders of later life needs further studies before satisfactory conclusions may be drawn.
