[Nutrition in old age].
A balanced diet before one gets old is relevant for the prevention of the diseases of affluence in old age. With decreasing physical activity the energy requirement decreases, and foods with high nutrient density are required to still supply all essential nutrients. Thirst may become a poor guide to sufficient fluid intake, which should be maintained by good drinking habits. As a consequence of disease or functional impairments, malnutrition may develop. Weight loss and anorexia are warning signals. Risk factors for malnutrition should be known and, if possible, eliminated. A poor nutritional status in the elderly increases morbidity and mortality: good nutrition in the last decades, on the other hand, is an important determinant of the quality of life.
