Protein Nutriture and Requirements of the Elderly

  • Chapter

Part of the book series: Human Nutrition ((HUNU,volume 6))

Abstract

Protein requirements of populations have been estimated for more than a century (see Munro, 1964a, 1985, for the historical references in the paragraph). In 1853 and again in 1865, Playfair reported the protein intakes of different classes of the population of Britain and concluded that the requirements of adults ranged from 57 g protein per day in the case of a subsistence diet to 184 g for laborers doing heavy work. Later in the same century, Voit and Atwater both supported generous allowances of protein for the average working man, but several subsequent investigators publishing just before World War I concluded that 30 to 50 g protein daily was not only adequate to maintain nitrogen balance but even improved the general health and vigor of young adults. Following the first global war, the League of Nations was formed, and in 1936 a health committee reported that the safe protein intake for adults was 1 g per kilogram body weight and that some of the protein should come from animal sources.
