The human body should be balanced and yin and yang should be harmonious, so people with hot constitution should eat more cold food, while those with cold constitution should eat more warm food. When it comes to the genus of food, Chinese medicine has the so-called "four qi", which means that food will have the functions of "cold, hot, warm and cold" when it enters the body. If it is neither warm nor hot, it belongs to "Ping", and each fruit has its own genus, which is generally divided into three categories: "warm", "cold" and "sweet". Ganping fruits include grapes, papaya, olives, plums, plums, loquats, hawthorn and apples. Warm fruits are jujube, chestnut, peach, apricot, longan, litchi, cherry and stone.

Durian, litchi, etc. all belong to high-calorie fruits, and hot fruits also contain warm fruits, such as longan, pomegranate, papaya, olive, etc., which belong to warm and hot fruits. It is best for people with cold body to eat hot fruits and warm fruits.

Warm fruits, such as apples, peaches, longan, rambutan, kumquat, ebony, cherry, red date, pomegranate, hawthorn, papaya, olive and ginkgo, are all warm fruits. Warm fruits are suitable for people with cold body, and can play a coordinating role for people with cold body.

Flat fruits, such as jackfruit, pineapple, grapes, black dates and plums, are all flat fruits. Flat fruits are suitable for all people, and can be said to be all is forgiven fruits, which can be eaten by people with cold constitution and those with hot body.

You can't eat more cold fruits, otherwise it will be harmful to your health. For example, pears are sweet in taste, and have the functions of stopping diarrhea, relaxing bowels and helping digestion. Regular eating can make the skin. However, because it is rich in sugar and potassium salt, eating too much will be harmful to the health of the heart and kidney. Patients with coronary heart disease, myocardial infarction, nephritis and sugar diseases can't eat more, while people with insufficient middle qi and mental fatigue can eat more as nourishing fruits.

Fruits such as pears, oranges and grapefruit have the functions of relieving cough, resolving phlegm, moistening the lungs and helping digestion, but eating more can easily cause gastrointestinal disorders, toothache, hemorrhoids and even skin macula. Therefore, people with stomach trouble and cold stomach had better eat less.

People with qi deficiency and spleen deficiency should be especially careful when choosing cold fruits such as watermelon, cantaloupe, mango, pear and banana, and it is best not to eat them. Qi deficiency generally refers to the deficiency of middle qi. These people generally have pale faces, thin bodies and can't eat. Spleen deficiency means poor digestion and slow intestinal peristalsis. Therefore, the more you eat cold fruit, the more you will reduce gastrointestinal peristalsis and make your muscles weak. Eating too much will lead to bloating due to indigestion. Therefore, the elderly and children with poor gastrointestinal function are not suitable for eating cold fruits. If they really want to eat, they can eat less after lunch and before dinner, but not too much.
