Autumn is three months from autumn to winter. Autumn is characterized by changing from heat to cold, and the yang disappears and the yin grows. Therefore, autumn health care must follow the principle of "nourishing and harvesting", in which diet health care should focus on moistening dryness and benefiting qi, focusing on invigorating spleen, nourishing liver and clearing lung, and focusing on moistening sweetness and cooling. In autumn, the weather is crisp, the air is dry, the temperature is gradually decreasing, the humidity is gradually decreasing, and the weather is hot and cold, changing rapidly. Therefore, drink plenty of water at ordinary times, keep the balance of water metabolism, and prevent chapped skin and invasion of evil fire; Eat more vegetables and fruits to supplement vitamins and minerals in the body, neutralize excess acidic metabolites in the body, and play the role of clearing away fire and detoxifying; Eat more high-protein plant foods such as beans, and eat less greasy and sticky. Try to eat less spicy food, such as onions, ginger, garlic, leeks, peppers and so on. It is not advisable to eat more barbecue to prevent the symptoms of autumn dryness from getting worse. The principle of "less spicy and more sour" should be implemented. The pungent taste is mainly lung, and the sour taste is mainly liver. Spicy taste can overcome sour taste. Therefore, in autumn, it is necessary to reduce pungent taste and calm lung qi, increase acid to help liver qi, and prevent lung qi from being too strong for liver, leading to stagnation of liver qi. You can eat soft foods such as sesame seeds, glutinous rice, honey, water chestnut, grapes, radishes, pears, persimmons, lotus seeds, lilies, sugar cane, pineapples, bananas, tremella, dairy products, and you can also eat health-care Chinese medicines such as ginseng, radix adenophorae, radix ophiopogonis, bulbus Fritillariae Cirrhosae, almonds, boat-fruited Sterculia, cordyceps sinensis, etc. It is advisable to eat more warm food and less cold food in autumn to protect and support the stomach. If you eat too many cold products or raw and unclean fruits and vegetables, it will lead to warm connotation and toxic stagnation in the body, causing diarrhea and dysentery. Therefore, there is a folk saying that "autumn melon is not good for the stomach", especially for the elderly, children and the weak. Due to the change from hot summer to cool autumn, people often feel more comfortable, and the emaciation caused by "boudoir summer" gradually recovers, and their appetite and spirit have improved, making autumn the best tonic season. In the process of tonic, it is based on the cool climate in autumn and the relative balance of yin and yang. The so-called flat compensation refers to the use of flat compensation that is not obvious in cold and heat, and it is all flat compensation. In addition, although yin and yang are relatively balanced in autumn, dryness is the main qi in autumn, and the lungs are vulnerable to dryness. When tonic, we should also pay attention to nourishing yin, promoting fluid production and moistening lung, and adopt the method of combining smoothing and moistening to achieve the purpose of nourishing yin and moistening lung. To moisten the lungs and dry, use soft foods such as sesame, honey and fruit. On the one hand, it can directly replenish human body's moisture and prevent people from being directly hurt by dry weather such as chapped lips; On the other hand, these foods or drugs can nourish lung yin and prevent the body from being affected by dryness and evil on the basis of lung yin deficiency, resulting in diseases. Drinking light salt water in the morning and honey water at night is not only a good way to replenish water and prevent constipation, but also an important part of health preservation and anti-aging. In short, autumn tonic should be warm, neither too hot nor too cold, and it should not hurt yang or consume yin. Food supplements are easy to obtain, although there are four flavors and five flavors, but after all, their strength is relatively weak. As long as you choose according to the symptoms when eating, not only the effect is obvious, but also there will be no discomfort. Eating in moderation is good for people, but eating without restraint hurts people. In autumn diet health care, we should pay attention to the timing of diet, so as to maintain the normal activities of gastrointestinal physiological functions and make them digest in an orderly manner, so as not to be disordered or overworked. Quantitative eating and drinking is to avoid gastrointestinal overload, prevent gastric function from being damaged, and cause indigestion or stomach trouble. Old people and children have weak digestive ability, so they should eat regularly and quantitatively. In addition, the way to eat every meal in autumn should be simple, not complicated. This is because the human body's yang and stomach are weak, and there are many kinds of foods to eat at each meal, which are not easy to digest and easily lead to stomach problems.
