英文摘要:

      With the aggravation of the problem of aging population in China, it has become an increasingly serious problem to pay attention to the health status of the elderly. As the human body enters the old age, its physiological functions are declining. These physiological changes affect the nutritional needs, digestion and absorption of the elderly. Therefore, it is necessary to carry out reasonable nutritional supplement according to the specific physiological characteristics of the elderly, that is, the health status of the elderly can not be separated from reasonable nutritional support. This paper reviewed the current research on the physiological characteristics and nutritional support of the elderly at home and abroad, discusses the changes of the physiological systems of the elderly, and the reasonable supplement of different nutrients, in order to provide a theoretical basis for how to maintain the health of the elderly, prevent disease, and delay aging.
