Spring corresponds to the liver, so eating more green food in spring is beneficial to the rise of liver qi. Spring foods such as cherries have the effect of strengthening the spleen and appetizing, and the iron content ranks first among fruits. Eating cherries can make people sweat, replenish qi, dispel wind and penetrate rash. Mango has extremely high nutritional value. The content of vitamin A is as high as 3.8%, which is 1 times that of apricot, and the content of vitamin C is also higher than that of oranges and strawberries. Mango contains essential nutrients such as sugar, protein, calcium, phosphorus and iron. Eating leeks often in spring can enhance the qi of the spleen and stomach and enhance the yang in the body, especially for people with kidney-yang deficiency. Yam is sweet and flat, which strengthens the spleen and benefits qi. Regular consumption can improve the body's immunity, enhance the phagocytosis of macrophages, and "destroy" bacteria and viruses invading the body in time. Patients with qi deficiency who are prone to sweating and repeated colds should pay special attention to moderately increasing the intake of yam in spring. Sun Simiao, a famous doctor in ancient China, said: "In spring, it is advisable to keep acid and sweeten it to nourish your temper." It means to eat less sour and eat more sweet in spring. Chinese medicine believes that when the liver qi is strong in spring, eating more sour food will make the liver qi excessive and damage the spleen and stomach, so eat less sour food. In spring, people have more outdoor activities than in winter, so they consume more energy and need more calories. But at this time, the spleen and stomach are weak and the digestive ability of gastrointestinal tract is poor, which is not suitable for eating greasy meat. Therefore, heat can be properly supplied by sweets. Jujube is such a good way to replenish spleen in spring.
