Extended data:
1. Eat less warm fruit.
But when choosing fruits, we should be careful not to choose some warm fruits, such as litchi, longan, cherry, guava and so on. These fruits belong to temperate fruits. If you eat too much, it will not only be harmful to human health, but also lead to excessive internal heat.
Eat less nuts.
When eating nuts in summer, you must keep a proper amount. 50 grams of melon seeds contain the same heat as a big bowl of rice, so nuts are also one of the foods that are very easy to get angry. Try to eat less in summer.
3. Drink less chicken soup
Summer is mainly tonic. If some restaurants still recommend black-bone chicken soup and old hen soup to make up the soup at the same temperature, it will be counterproductive. Choose duck soup or pigeon soup.
4. Eat less cold food
The weather is hot in summer. Although cold food can temporarily relieve dryness and heat, eating cold food will stimulate the oral cavity, which will easily lead to rapid cooling of salivary glands, tongue taste nerves and periodontal nerves, and sometimes even paralysis. It will irritate the throat, cause adverse reactions such as pharyngitis or toothache, stimulate the spleen and stomach, affect the secretion of gastric juice, reduce appetite, and cause gastrointestinal diseases such as indigestion, anorexia, abdominal pain and diarrhea.
