[Nutrition as prevention of illness in the elderly].
In the industrialized countries, nutrition-related diseases are among the most common health problems (not only in the aged, but also in the population as a whole). To date, the risks to health, and thus quality of life, of overnutrition, but in particular of a one-sided diet and malnutrition, have received too little attention in the area of medical care.
