Studies have shown that when people enter the age of 60, taste buds shrink by 30%, and by the age of 70, taste buds are only about 36%. In this way, the taste discrimination function of the tongue is reduced, and the salty taste is reduced the earliest, followed by the sweet taste. Especially in summer, high temperature affects appetite and digestion. Some elderly people often complain that they have a "bad appetite" and "can't eat well". How can the elderly eat well?

Firstly, we should increase the intake of trace element zinc, which can affect the normal metabolism of protein in cells, participate in the synthesis of taste, and enhance the function and nutrition of taste buds. So eat more foods rich in zinc, such as oysters, lean meat, fish, eggs, bean products, walnuts, peanuts and so on. In order to increase the zinc content in the body and make the taste sensitive.

Secondly, we should pay attention to oral hygiene, insist on gargling after meals and brushing our teeth in the morning and evening, and clean up the food residue between our teeth in time to prevent the growth of bacteria.

Moreover, if you have dental diseases, you should treat them early, insert them in time, keep the chewing function, chew the vegetables, fully contact with the taste buds, and increase your appetite.

Fourth, cheerful mood, cheerful spirit, paying attention to mental health of diet, not wanting to talk about unpleasant things when eating, quitting smoking and drinking less, and living a normal life will increase the sensitivity of taste buds. Do more outdoor sports and work as much as possible to promote the emptying of the stomach, which can enhance the hunger before meals and increase appetite.

In addition, taste buds are more sensitive to soup than solid food, so the elderly can drink vegetable soup, noodle soup, egg soup, wonton and so on when eating.

Finally, the temperature of the food should be appropriate, which is also very important for the elderly. Experiments show that the optimum temperature for taste buds is 20℃-25℃.
