During the hot summer, many people tend to have a poor appetite, and their digestive function will also decline. What's more, they would easily suffer from some symptoms such as weakness and fatigue, discomfort in intestines and stomach, and even gastrointestinal disorders. Therefore, in the hot summer, it is necessary to pay attention to the diets and take some corresponding countermeasures.

First, pay attention to eat more bitter food. The alkaloid contained in the bitter food has some pharmacological effects, such as relieving summer heat, promoting blood circulation, relaxing blood vessels and so on. Properly eating some bitter food in summer, such as bitter gourd, bitter herbs, as well as beer, tea and coffee, can not only refresh your brain, but also can improve your appetite, and invigorate the spleen and stomach.

Second, pay attention to provide more salt and vitamins. During the hot summer, it is better for everyone to take in more nutrients such as vitamin B, vitamin C, calcium and sodium every day. It can reduce the consumption of carbohydrates and tissue proteins in the body. You can eat some foods rich in the above nutrients, such as watermelon, cucumber, tomato, beans, animal liver and so on.

Third, be careful not to drink too much cold drinks. When it is really hot, drinking some cold drinks properly can play the effect of driving away summer heat. However, ice cream or ice-cream bricks are all made by milk, egg powder and sugar, so you should not eat too much. Otherwise, it will stimulate the stomach and intestine, causing diseases such as abdominal pain and diarrhea.

Fourth, pay attention to the supplement of potassium. As people sweat a lot in summer, so the loss of potassium with the sweat will increase. Lack of potassium will cause hypokalemia, which will lead to symptoms such as fatigue and weakness, dizziness and headache, loss of appetite and so on. The most effective way to prevent potassium deficiency in hot summer days is to eat more foods containing a lot of potassium. Fresh vegetables and fruits contain plenty of potassium, so you can eat some strawberry, apricot, litchi, peach and other fruits. Vegetables such as cabbage, green onion, soybeans are also rich in potassium.

Besides the above notices, you should also pay attention to the hygiene of the food, as well as the regularity of the meal in summer. All of these notices will bring you a healthy diet in summer.
