According to the principle of "four seasons have their own emphasis" in traditional Chinese medicine, the focus of spring health preservation is "nourishing the liver". Besides paying attention to emotional conditioning and moderate exercise, a reasonable diet is also one of the important ways to nourish the liver. Specifically, there are three ways to nourish the liver with diet in spring:

(1) It is advisable to keep acid to sweeten it.

Sun Simiao, the king of medicine in the Tang Dynasty, said: "It is advisable to keep sour and sweet in spring to nourish the temper." . This means that when spring comes, people should eat less sour food and eat more sweet food to supplement the qi of the spleen and stomach and avoid excessive liver qi. Therefore, you can choose to eat more yam, jujube and other foods in spring.

(2) Eat more spinach.

Spinach has the functions of nourishing yin and moistening dryness, soothing the liver and nourishing blood, improving eyesight and protecting eyes, and has a good auxiliary treatment effect on hypertension, dizziness, anemia and eye discomfort caused by liver yin deficiency in spring. Studies have found that eating spinach 2~4 times a week for middle-aged and elderly people can reduce the risk of retinal degeneration.

(3) It is advisable to fill the dirty with dirty.

According to the theory of traditional Chinese medicine, the liver begins with the eye, and the quality of vision is closely related to the liver. Animal livers such as pig liver and chicken liver have the function of nourishing liver. Old friends can eat more of these foods when their eyesight drops.
