On the basis of limited available data, calculation of vitamin needs based on regression lines resulted in estimates (mg/day) of: > 150 for ascorbic acid, > 3 for riboflavin, > 3 for vitamin B6. Expanding the current practice of supplementing micronutrients at a level of 100% RDA (in tablet form) that already exists in some elderly societies should be considered after a comprehensive study in a large group of elderly people.

In our small group of elderly, energy derived from protein was higher than that in most of other studies reviewed, and that from fat was higher than in half of those studies. These values were remarkably higher than the suggested values. Energy derived from carbohydrates was close to that found in other studies. Monitoring of dietary macronutrients might improve the nutritional and the physiological status of the elderly.
