First of all, sweating in summer is easy to cause imbalance of body fluid metabolism. The balance between water and electrolyte is an important factor to keep the internal environment relatively constant. If you sweat a lot, you will lose too much water, sodium chloride and water-soluble vitamins (mainly vitamin B 1 C), which will lead to the disorder of water and salt metabolism and the imbalance of acid-base balance and osmotic pressure in the body. Due to a large amount of perspiration and chloride loss, the chloride ion reserve necessary for the formation of gastric acid in the blood will be reduced, resulting in a decrease in the acidity of gastric juice; Drinking a lot of water because of thirst will dilute stomach acid. These changes will directly or indirectly affect the digestive function and cause loss of appetite. In addition, due to the high temperature, the blood in the body is mostly concentrated on the body surface, which is easy to cause digestive tract ischemia, inhibit saliva secretion, reduce amylase activity and gastric juice secretion, resulting in loss of appetite and digestive dysfunction.

Therefore, corresponding measures should be taken to scientifically arrange summer diet according to the characteristics of loss of appetite in summer.

Pay attention to food hygiene:

Food raw materials should be fresh, meals should be cooked and eaten now, and leftovers should be avoided as much as possible; Raw fruits should be washed, scalded or disinfected; When making cold salad, vinegar and garlic should be added to the seasoning, which can not only flavor, but also sterilize and stimulate appetite. Don't be greedy for cold food to prevent pathogens from taking advantage of it.

Don't overeat cold drinks;

When the climate is hot, eating some cold drinks properly can play a certain role in dispelling summer heat, but you should not eat too much. Ice cream is mostly made of milk, egg powder, sugar, etc. Although the nutrition is acceptable, overeating will reduce the temperature of gastrointestinal tract, cause irregular contraction of gastrointestinal tract and induce abdominal pain. Drinking too much will damage the spleen and stomach, affect appetite, and even cause gastrointestinal dysfunction.

Pay attention to supplement salt and vitamins:

Due to excessive sweating, a large amount of sodium chloride is lost, so we should pay attention to supplementing salt while supplementing water, and drink some salty boiled water every day to keep the acid-base balance and osmotic pressure in the body relatively stable. As for vitamin supplements, you should eat more foods rich in vitamins B 1, B2 and C in summer, such as watermelon, cucumber, tomato, beans and their products, animal liver and kidney, etc., and you can also drink some fruit juice.

Hot weather should be cleaned up:

In the aspect of diet nourishing, the principle is to tonify, strengthen the spleen, dispel summer heat and eliminate dampness. Fat, sweet, thick and hot products should not be eaten, but foods with light and nourishing yin, such as duck, goose, crucian carp, lean pork, beans, coix seed, lily, etc., can be made into a variety of delicious dishes after reasonable cooking, which can not only stimulate appetite, strengthen nutrition, but also relieve summer heat and keep fit.
