Add some salt to vegetables and soup, because at high temperature, you sweat a lot, and a considerable amount of salt is excreted in the body with sweat. The supply of salt, including the salt in the ordinary diet, is only 20-30 grams per day, but not too much.

Secondly, drink more drinks, but pay attention to drinking a small amount of water many times, each time not exceeding 300-500 ml, and the temperature of cold drinks should be 10 degrees Celsius. Tea, cocoa, coffee, mung bean soup, dark plum soup, etc., can not only replenish water, but also have a mild excitement, which is helpful to relieve fatigue and improve appetite. It's best to eat more watermelons in summer to quench your thirst.

Also, properly supplement vitamins. Water-soluble vitamins, such as vitamin B 1, vitamin B2 and vitamin C, should be considered first. Generally speaking, it is best to contain vitamin B 10.5, vitamin B20.3-0.5mg and vitamin C 150-200mg in daily diet.

Finally, eat more fruits, vegetables, lean meat, animal offal, chicken and duck eggs. On the contrary, the supply of fat should be reduced appropriately. If it is too greasy, it will cause anorexia. In summer, you often lose your appetite, so you should pay attention to color, smell and eat some coarse grains properly. Hot and sour condiments can stimulate appetite, and you can eat more appropriately.
