Spring is also the season of liver qi and hair growth. Chinese medicine advocates eating more sweet food and less sour food in order to maintain a good temper, drink moderately and eat less rice cakes to avoid hurting the spleen and stomach. It is advisable to eat more foods that encourage yang, eat more light and warm foods, eat more fresh foods, and eat less greasy foods such as high fat and high calorie.

In summer, it is hot and rainy. At this time, the summer heat easily invades the body, often reducing appetite and weakening digestion. Most people don't want to eat greasy food. So in the diet, it is suitable to eat some light and digestible foods, especially some nutritious fruits and vegetables.

In autumn, the spirit of the sun began to fade and the weather became dry. Diet, should eat less spicy food, such as onions, ginger, garlic, peppers, etc., suitable for eating honey, yam, glutinous rice, sugar cane, loquat, sesame, glutinous rice, pineapple, dairy products and other soft and lung-moistening foods.

Of course, health care also has its own environment. The characteristics of the four seasons in different regions are different, so health preservation should be based on both the four seasons and the geographical environment. For example, in southern China, the weather is hot in summer, the climate is humid and rainy, and the temperature will be very high in winter, especially in Guangdong, Guangxi, Yunnan and Hainan. There is little difference between the four seasons, and there is basically no autumn and winter. In the northern region, there are obvious differences between the four seasons, and temperature and humidity have great influence on the human body.

Therefore, when maintaining health, we should also learn to master the appropriateness and taboos of the four seasons diet flexibly according to our own physique, age, illness, physiology and environment.

Following the changes of the four seasons is of great significance for health preservation, and the most important thing is health preservation.
