[Nutritional requirements of elderly].
Nutritional requirements of the elderly (more than 70 years old) are not yet well known. The aging-associated changes of the body composition with decrease of height, bodyweight, fat free mass, increase of adipose tissue and the decrease of physical energy expenditure modify the nutritional requirements. Owing the insufficiency of our scientific knowledge the energy and protein requirements of elderly people are assumed by W.H.O. experts as 70 p. 100 of adults' ones. Water, minerals, trace elements and vitamins requirements would be similar to those of adults. The quality of meals and their hedonic properties are important factors for the preservation of appetite.
