1, the care of “Yang Qi”, do not over cold summer heat, hot temperatures, easy to trigger the internal fire, causing harm to the body. At this time, you can choose to eat cool vegetables such as winter melon, cucumber, tomatoes, bitter melon, watermelon, melon, grapefruit, grapes and other fruits, as well as appropriate cold drinks, etc., to help cool down the summer heat, but do not eat too much cold food, so as not to damage Yang Qi. The Sun Zhen Zhen health song commentary said: “the summer time, the volatile yin within, decay slightly late, melon and fruit garden vegetables, more will produce phlegm, ice water and cinnamon syrup, raw and cold value, grammed especially difficult.” It means that the body is hot outside and cool inside in summer, do not eat too much cold food to hurt Yang Qi, otherwise indigestion, diarrhea and loose stools and other diseases can occur. From the perspective of modern medicine, the high temperature in summer produces a series of hot physiological reactions in the human body. Sweat more, drink more, appropriate to eat some cold drinks, not only to quench the thirst, but also to help digestion, promote appetite, beneficial to health. However, if not controlled, it is easy to damage the spleen and stomach Yang Qi, contrary to the principle of “spring and summer nourishing Yang”, may cause stomach pain, abdominal pain, diarrhea and other digestive system diseases. Especially for the elderly, the spleen and stomach yang energy has gradually declined, excessive consumption of cold and raw food will further injure the kidney yang and cause more than diarrhea. Children’s digestive function is not yet full, in summer and susceptible to summer heat and moisture, such as eating cold food, especially ice cream, drinks, etc., is very likely to damage the transport function of the spleen and stomach, long-term loss of appetite, abdominal pain, abnormal stools and other symptoms. 2, in line with the summer “long”, pay attention to nutrition summer main “long”, need to increase nutrition to meet the body’s metabolic needs. However, the hot summer temperatures, and easy to have dampness intrusion, easily lead to spleen depletion, stagnation of transportation, digestive capacity decreased. Therefore, large fish and meat, greasy and thick diet should not be eaten, fried and fried, too spicy food should also be eaten less, so as not to increase the burden on the spleen and stomach, but also to reduce the occurrence of fire to help heat. The Sun Zhen Zhen health song commentary says: “three days of volcanoes, food especially light taste to reduce, so that the spleen and stomach is easy to grind, then abdominal diseases are not born.” It means that in summer we should eat a simple diet that the spleen and stomach can easily digest, so as to eliminate the occurrence of gastrointestinal diseases. A light diet is what is usually called a “light meal”, with the main food being grains and cereals and the side dishes being beans, vegetables, fruits and mushrooms. Light diet is not a complete vegetarian diet, meat contains essential proteins, a complete vegetarian diet is prone to malnutrition, so the meat cooking should be steamed, boiled, reduce frying, less oil and salt, try to maintain the original taste of food. Meat is best eaten at lunchtime, and the skin and fat can be removed when eating meat to reduce the fat content. Daily protein intake of 100 grams is appropriate, and preferably more than half for fish, shrimp, chicken, duck, eggs, milk, soy products and other easily digestible and absorbable high-quality protein. 3, adapt to individual physique Conformity to natural changes is a general requirement, but also need to be combined with the specific circumstances of each individual to adjust. In simple terms, according to the yin and yang can be classified to the body imbalance, roughly divided into Yang deficiency or Yin blood deficiency two categories. People with Yang Qi deficiency have insufficient “growth” in summer and should supplement Yang Qi to help “growth”; people with Yin and Blood deficiency are prone to internal fire caused by external heat in summer, resulting in pathological fire and damage to Yang Qi, so the goal of nourishment is to nourish Yin and Blood so as not to hinder the normal growth of Yang Qi. The goal of nourishment is to nourish Yin and Blood so as not to hinder the normal growth of Yang energy. pepper, ginger, mutton, etc. For people with blood deficiency, dietary regimen can be consumed mulberry, lychee, black fungus, jujube, pork, turtle and other foods; people with yin deficiency, eat more plums, grapes, watermelon and other fruits, as well as duck, beef, fish and other foods, onions, ginger, pepper and other hot and dry spices should be eaten sparingly. 4, summer diet to pay attention to health Summer people are often easy to drink cold, eat more fruits and melons, but this time bacteria and other microorganisms also grow active, do not pay attention to dietary hygiene is easy to suffer from enteritis, dysentery and other diseases, so develop good dietary hygiene and personal hygiene habits is the main measure to prevent summer gastrointestinal diseases. Pay attention to washing fruits and vegetables, food should not be left for a long time, and pay attention to keeping the abdomen warm at night while sleeping.
