1. You can eat more aquatic products such as ducks, fish, crabs and shrimps. According to the Daily Materia Medica, ducks can "nourish the yang of the five internal organs, clear away fatigue, invigorate qi and promote water circulation, nourish the stomach and produce fluid, and relieve cough and asthma." It can be seen that eating ducks in summer can not only supplement excessive nutrition, but also eliminate the adverse effects of summer heat on human body. For those with low fever, weakness, loss of appetite, dry stool and edema, eating duck is the most beneficial.

2. Optimize three meals. Summer meals should be arranged according to the summer temperature and physiological changes of the human body. Fruit salad can be one of the ideal breakfast foods. Sweet things such as bananas, figs and cherries are best eaten separately from sour things such as pineapples, oranges and fruits. Don't eat bread with butter, cheese and other fats. The best partner of bread should be salad.

3. Choose the best drink. Yogurt is an ideal drink in the morning and evening. Drinking yogurt in the morning can replenish protein and energy. Adding two spoonfuls of cereal to yogurt at night can produce growth hormone and promote muscle growth. The trace element selenium contained in freshly squeezed orange juice can also enhance people's disease resistance. In addition, the flavonoids contained in it can increase the efficacy of vitamin C by 2 times. Tea, rich in potassium, can make up for the loss of potassium due to excessive sweating. According to the determination, the average content of potassium per 1 grams of tea is 1.7 mg for green tea and 24.1 mg for black tea.
