"Reducing acid and increasing sweetness" has long been a dietary principle of traditional Chinese medicine in spring. Sun Simiao, a famous doctor in the Tang Dynasty, wrote in the preface to "Dietotherapy for Thousands of Women": "On the 72nd day of spring, the acid is preserved and sweetened to nourish the nature." Chen Zhi, a health care scientist in the Song Dynasty, pointed out in more detail in his book "Caring for the Aged and Caring for the Family": "In spring, the liver is full of qi, belonging to wood, which tastes sour, and wood can overcome the soil, and the soil belongs to the spleen, which is the main sweetness. In spring, the taste of its diet should be reduced to sweetness to nourish its temper. " "Reducing acid and sweetening" is actually a seemingly simple "reducing acid and sweetening" of suppressing liver and strengthening spleen. In fact, it contains the profound meaning of five flavors, five internal organs, five elements and even "vitality" of traditional Chinese medicine. Chinese medicine believes that people grow in nature, and all human activities should conform to the law of the growth of all things in nature and correspond to nature. Spring is the time when everything grows, and the five elements belong to wood. Among the five internal organs, the liver governs discouragement and happiness, which accords with the vitality, vigor and vegetation of the sun in spring, so the liver belongs to wood and governs spring. Generally speaking, the qi and blood of the five zang-organs are most vigorous in the season when the zang-organs are dominant, and the qi and blood of the liver are vigorous in spring. If the wood is strong and the liver qi is excessive, it will directly damage the spleen belonging to the soil. At this time, it is necessary to suppress the liver and tonify the spleen. The best way to restrain excessive liver qi without damaging it is to adjust diet, which is related to five flavors. The five flavors in the diet enter the five internal organs, sour taste into the liver, bitter taste into the heart, sweet taste into the spleen, spicy taste into the lungs and salty taste into the kidney. "Su Wen? Anger reaches heaven and says, "Yin gives birth to five flavors; Yin, five houses and five smells hurt. So the taste is too sour, the liver is full of body fluid, and the temper is absolute. "The yin here refers to the yin essence of the five internal organs, and the five palaces refer to the five internal organs. The meaning of this sentence is that the yin essence of the five internal organs comes from the five flavors of diet, but if the five flavors of diet are too strong, it will hurt the five internal organs that store essence. If you eat too much sour food, your liver qi will be too strong and your temper will not work. Liver qi is already strong in spring, so you can't "add fuel to the fire" and eat too much sour food to encourage liver qi. Therefore, the spring diet should first be less acidic; Secondly, it is necessary to increase the sweetness, because the spleen and stomach are the acquired foundation of the human body and the source of qi and blood biochemistry. Strong liver and weak spleen in spring will affect the function of five internal organs. When the sweetness enters the spleen, it is necessary to help the spleen resist the strong liver qi in spring. Naturally, it is necessary to add sweetness to the diet to replenish the soil and strengthen the spleen. " Sour "≠ acidic food" sweet "≠ sweet food It should be noted that the" acid "mentioned here is different from acidic food (such as chicken, fish, meat, eggs, rice, etc. ) is often said now; And "sweet" doesn't just mean that food tastes a little sweet. In addition to sweet and sour, Chinese medicine classifies foods and drugs with astringent effects as sour; Foods and drugs with nourishing and soothing effects are classified as sweets. For example, although pomegranate is very sweet, its nature is astringent, so it is classified as acidic food, which has the effect of convergence and blood supply; And yam, lentils, walnuts, cauliflower, lettuce, Chinese cabbage, whole grains such as black rice, sorghum, millet, oats and so on. Although it is tasteless, it is listed as a sweet food to reduce acid and sweeten. "It is not simply to be less jealous and eat more sugar." Reducing acid and sweetening "is to suppress the liver and strengthen the spleen through diet conditioning." In spring, you can choose foods such as soybean sprouts, mung bean sprouts, tofu, lobster sauce, barley, wheat, jujube, lean meat, fish, eggs, peanuts, sesame, oranges, bananas, honey, ginger, onions, garlic, etc. These foods have the functions of promoting hair growth and nourishing, and you can also eat some fresh vegetables, such as bamboo shoots, leeks, rape, spinach and celery. For patients with spleen and stomach weakness and deficiency of both qi and blood, red dates, medlar and glutinous rice porridge can be added for dinner to strengthen the spleen and stomach and replenish qi and blood. For people with dry skin and constipation caused by hot inflammation in spring, carrots, spinach and japonica rice can be used to cook porridge and take it in the morning, which has the functions of clearing away heat and soothing the liver, moistening the intestines and relaxing the bowels. Use seasonal wild vegetables, such as shepherd's purse to cook porridge, wrap jiaozi and make soup. It is a good product for spring health. Warm reminder, honey can't be eaten with tofu and leeks; Garlic cannot be eaten with honey and crucian carp; Leek can't be eaten with white wine and beef; Onions can't be eaten with tofu; It is not advisable to eat onions during taking Liuwei Dihuang pills; Radish can't be eaten with fungus; Yam should not be eaten with carp and kansui; Jujube can't be eaten with shrimp skin.
