In summer, light, bitter, cold, nutritious and digestible food is better. Don't eat sticky and indigestible food, and don't be too full and hungry. Pay attention to strengthening the spleen and nourishing the stomach to promote digestion and absorption. In summer, when the temperature is high, people sweat more and drink more water, the gastric acid is diluted, the secretion of digestive juice is relatively reduced, and the digestive function is weakened, resulting in loss of appetite. In addition, people overeat cold food in hot days, which leads to gastrointestinal dysfunction or unclean food, which easily leads to gastrointestinal discomfort and even food poisoning. Therefore, the diet should be light in summer, which can promote appetite and achieve the purpose of health care. In summer, you should eat foods that benefit water and moisture, because summer is hot, high temperature and humidity, and it will also invade the human body. Because of the hot weather, you like cold drinks, and if you drink too much water, it will make the water wet and strengthen the spleen, the spleen and stomach will rise and fall, and the transportation function will be blocked, so water will accumulate. Eating moist and dry food can strengthen the spleen, which can restore the function of ascending, descending and transporting, so it can remove dampness. Eat more bitter food, such as bitter gourd. Summer is very hot, hot and humid. Eating bitter food can clear away heat and relieve summer heat, dry dampness and strengthen spleen, and increase appetite. Sour food can be astringent, and sweating in summer is easy to hurt yin. Eating acid can stop sweating and diarrhea. For example, tomatoes have the functions of promoting fluid production, quenching thirst, invigorating stomach and promoting digestion, cooling blood and calming liver, clearing away heat and toxic materials, and lowering blood pressure. In summer, the appetite decreases and the function of spleen and stomach is relatively dull. At this time, eating light products will help stimulate appetite, increase food intake, strengthen the spleen and help transport. Eating too much fat will cause stomach qi stagnation, damage the spleen, affect the digestion and absorption of nutrients, and be harmful to the body. Therefore, we should pay attention to the selection of mung beans, white lentils, watermelons, lychees, lotus seeds, silkworm excrement, buckwheat, jujube, pork tripe, pork, beef, tripe, chicken, pigeon meat, quail meat, crucian carp, turtle, royal jelly, honey, duck meat, milk, goose meat, tofu pulp, sugar cane, pears and so on. You can't overeat in summer, that is, you can't eat enough, especially at dinner. The proverb says, "Eat less and live to ninety-nine." Su Wen in Huangdi Neijing pointed out that "diet should be moderate" and "not excessive". The digestion of old people and children is not strong, especially in summer. If they eat too much and can't digest it, it is easy to damage the spleen and stomach and lead to stomach problems. If you are 80% full, your appetite will continue to increase. Summer is hot, and the gastrointestinal function is weakened by it, so in terms of diet, it is necessary to mix well, which will help to enhance the function of the spleen and stomach. Flour should be properly matched with rice and coarse grains, and eat more. Coarse grains should be eaten three times a week, and thin dry food should be properly arranged. Two thins should be eaten in summer, pasta and soybean milk in the morning, Chinese rice and porridge in the evening. In summer, vegetables such as vegetables, melons and beans are the main vegetables, supplemented by vegetarianism. Meat is preferably lean pork, beef, duck and fish and shrimp. The elderly are mainly fish, supplemented by lean pork, beef and duck. In summer, you should eat on time. Don't eat if you want, or don't eat if you don't want. This will disturb the normal activities of the spleen and stomach, make the physiological function of the spleen and stomach disorder, and lead to stomach diseases. Eat less cold food and cold drinks, especially ice, in summer. The digestion and absorption capacity of the spleen and stomach of the elderly is gradually declining, and the digestive function of children and children is not yet full. In summer, they will be invaded by damp heat, which will affect the digestion and absorption function of the spleen and stomach. If you eat cold food and drink cold drinks, it will damage your spleen and stomach. Cold food is cold food, and the combination of cold and dampness will make the spleen consume around the stomach, leading to diarrhea and abdominal pain.
