In three meals a day, pay attention to eat more bitter food. Bitter food is not so delicious in taste, but it is healthy food in summer. Alkaloids contained in bitter food have pharmacological effects such as relieving summer heat, promoting blood circulation and relaxing blood vessels. Eating bitter gourd and bitter vegetables or drinking bitter drinks such as beer, tea, coffee and cocoa in dog days can not only clear people's inner troubles, refresh their minds, but also stimulate appetite, strengthen the spleen and benefit the stomach.

Pay attention to vitamin supplementation.

In high temperature season, human metabolism is accelerated, and it is easy to lack various vitamins. At this time, you can selectively and quantitatively supplement some vitamins, preferably complementary food. You can choose some foods rich in vitamins and calcium, such as watermelon, cucumber, tomato, beans and their products, animal liver and kidney, shrimp skin and so on. And you can drink some juice.

Don't forget to add salt and potassium.

If you sweat more in summer, more salt will be lost in your body. Therefore, we should pay attention to eating more salty food to supplement the salt lost in the body and achieve the balance needed by the body. In addition, excessive sweating can also lead to excessive loss of potassium ions in the body. The specific symptoms are burnout and loss of appetite. Fresh vegetables and fruits contain more potassium, so you can eat some fruits such as strawberries, apricots, lychees, peaches and plums in moderation, and vegetables such as green vegetables, green onions, celery and edamame are also rich in potassium. Tea contains a lot of potassium. Drinking more tea in summer can not only cool off the heat, but also supplement potassium, killing two birds with one stone.
