Autumn is the harvest season. From the perspective of TCM health preservation, autumn health preservation can not only prevent and treat common and frequently-occurring diseases in autumn, but also enhance the adaptability of human body to the cold climate after autumn and improve physical fitness. As the old saying goes, "One summer is disease-free, and three points are empty". After beginning of autumn, the temperature gradually changed from warm to cool. Although the climate is cool in the morning and evening, people are easily tired and weak. The best way to prevent autumn deficiency is to exercise properly and keep enough sleep.

Traditional Chinese medicine has nourishing yang in spring and summer, nourishing yin in autumn and winter, and nourishing yin in autumn lies in nourishing yin rather than clearing heat. There is an essential difference between the two. The former focuses on nourishing, while the latter focuses on drainage, so the choice of ingredients in autumn is mainly "moistening lung and clearing dryness, nourishing yin and promoting fluid production", such as pears, sugarcane, water chestnuts and water chestnuts. You can't choose "heat-clearing" foods, such as watermelon, bitter gourd and iced soda. After beginning of autumn (early autumn), you can eat more food such as coix seed, lotus seed, yam, lentils and white radish. On Mid-Autumn Festival, the weather gets cold and the climate is dry, and many people will have dry mouth and defecate. At this time, they should eat more moist foods, such as raw pears, water chestnuts, grapefruit, tremella, sugar cane, sesame seeds, walnuts, glutinous rice, honey, Sydney, yogurt and so on.

In autumn, people with weak constitution, middle-aged and elderly people and patients with chronic diseases can eat some tonics such as red dates, lotus seeds, Euryale euryales, yams, lilies and chestnuts. Pay attention to eating spicy and fragrant products such as ginger, raw onion, raw garlic, pepper, pepper and minced garlic, as well as smoked, strong liquor and greasy food in autumn.
