【Abstract】 The nutritional survey of 170 intellectuals over sixty years old in Zhong-shan University showed that their mean daily intakes of energy and protein were over 100% of the recommended dietary allowance (Institute of China National Center for Preventive Medicine). The protein provided 11.6%, fat 34.2% and carbohydrate 54.2% of total energy intake; and 44.3% of protein originated from animal sources.The physical and laboratory findings indicated that their anemia rate was about 55.0% and hyperlipidemia rate was 54.7%. The morbidity rate of parenchymal diseases of one or more important organs was 72.9% and most of them were hypertension, coronary heart disease, pulmonary emphysema and cerebral arteriosclerosis etc.The morbidity rate of hypercholesterolemia and coronary heart disease of old people in this group was markedly higher than in Guangzhou old people house and in Bama county,Guangxi province,and the important cause of this might be due to high energy, protein and animal fat intake and lack of physical activity.更多还原
