Abstract
In recent years, the phenomenon of population aging has become increasingly severe, and population aging and chronic diseases in the elderly have become a serious global challenge that must be addressed immediately. Due to deteriorating physiological functions, the elderly's metabolic rate has slowed, their ability to absorb and digest nutrients is poor, and their resistance to disease has progressively diminished. Therefore, the elderly should adhere to a rational and scientific diet to supplement the various nutrients their bodies require for optimal health. In this paper, the author examines the nutritional requirements of the geriatric and the diseases associated with nutritional deficiencies, such as osteoporosis, hyperglycemia, stomach diseases, intestinal diseases, and dental diseases, among others. Suitable preventative measures are also proposed, which can strengthen the dietary structure of senior citizens in China, improve their health, and reduce their risk of chronic diseases to a certain degree.
