Pomelo is a non-herbal medicine, and there is no such thing as cool or hot. Pomelo as a food can supplement the nutrients needed by the body. Coolness and heat belong to the judgment of Chinese medicine on the medicinal properties of Chinese herbs, while pomelo as a food does not have this statement. According to the data of Chinese food composition table, pomelo has high water content, about 89 grams of water per 100 grams, and is rich in vitamin C, pectin, natural folic acid and minerals such as potassium and other nutrients, which can be used as a good source of food for it. Meanwhile, the edible portion of pomelo contains only 42 calories per 100 grams, which is suitable for people with low-fat dietary needs. It is recommended to consume grapefruit with protein-rich foods such as eggs and soybeans for balanced nutrition.
