Eating time refers to the time taboo of eating food, that is, when to eat what is inappropriate and when to eat what is good. Mainly refers to the following situations: First, seasonal food taboos. Zhang Zhongjing, a famous doctor in the Han Dynasty who was regarded as a medical saint by China, said in his famous book "A Brief Introduction to the Golden Chamber": "You don't eat liver in spring, heart in summer, lung in autumn, kidney in winter and spleen in the fourth place." This is what the ancients in China called the four taboos of diet: spring liver, summer heart, autumn lung and winter kidney, which is also the taboo basis of diet in China court.

Why can't you eat liver in spring? What to eat, what to make up. In spring, the liver qi is very strong and the temper is very weak. Eating liver in spring is not stronger and weaker. This is the reason why spring, summer, autumn and winter are taboo. People who know dietary taboos divide the four seasons into four flavors: sour in spring, bitter in summer, spicy in autumn, salty in winter and smooth and sweet. This means eating different foods in different seasons.

The second is to eat all day. The diet during the day can't meet the physiological needs, and the diet at night can't meet the physiological standards. It is not advisable to drink too much at dinner. Drinking will accelerate blood circulation, make people excited and affect sleep. Drinking alcohol regularly at night will also lower the blood sugar level and cause "neurohyperglycemia". Avoid overeating or overeating at dinner, which will mechanically enlarge the stomach and lead to indigestion and stomachache. If you go to bed immediately after eating, it will not only be difficult to fall asleep because of the tension and peristalsis of the gastrointestinal tract, but also affect the rest of the brain.

The third is to avoid eating three meals. All cakes, finished drinks, cooked food, semi-finished products and meals are forbidden for breakfast.

The canteen does not use all plastic and chemical fiber products, does not eat all dry food, and only eats eggs; Don't eat too spicy lunch, don't drink, don't simply handle it; Avoid eating too late for dinner, eating too much, eating a lot of eggs, meat, fish and other thick flavors, and drinking too much.

Fourth, taboos before, during and after meals. Avoid drinking water before and after meals; Avoid eating cold drinks before and after meals; It is not advisable to smoke while eating; It is not advisable to sleep, work, drink tea and eat fruit immediately after meals.
