How should the elderly take daily zinc supplements?

　　People rely on their tongue to distinguish the taste of food. The surface of the tongue is densely covered with many tiny taste buds. As people age, their taste buds shrink physiologically and their taste sensitivity decreases. Taste aging accelerates after the age of 60, elderly The perception of salty taste is the most degraded, about 11 times that of young people.

　　Xiyuan, China Academy of Chinese Medical Sciences Hospital Professor Gao Pu from the Center for Geriatric Diseases believes that the main reason for the degradation of taste in the elderly is zinc deficiency. The daily zinc requirement for adults is 15 mg, while the average intake of elderly people in my country is only 4-7 mg. Many elderly people eat little or no meat, fish, eggs, and shrimp, which makes them prone to zinc deficiency. When you find that your sense of taste is aging, you can eat more oyster meat, walnuts, hazelnuts, and shiitake mushrooms. In addition, taste buds are the slowest to experience sour taste. Therefore, adding some lemon juice, tomatoes, plum juice, vinegar, etc. when cooking can also increase appetite.
