【Abstract】 The nutritional condition of 33 aged males (60-70 years old) in Changsha was surveyed in May, 1985. It was found that the mean energy intake 2593 Kcal/d and the consumption 2615 Kcal/d were approximately in balance. The mean intake of protein 74g/d, and 44% of protein sources which were from animal and bean might well meet their need. As for calory contribution, fat was 30.9%, carbonhy-drate 54.7%, so the fat/carbonhydrate ratio was rather. high. The riboflavin and vitamin A intake was lower than the Recommended Dietary Allowance. Vitamin load tests showed that 64% of the subjects were depleted in thiamin, 45% riboflavin and 69.7% ascorbic acid. It is indicated that the subjects’ intake of vitamin B1, B2 and C could not neet the need of the elderly people.更多还原
