Who should not eat watermelon in summer?

　　[These types of people should not eat watermelon:]

　　1. Diabetic patients

　　Watermelon contains about 5% sugar, mainly Grape Sugar, sucrose and some fructose, which means that eating watermelon will cause blood sugar to increase. Normal people can maintain blood sugar and urine sugar at normal levels because they secrete insulin in a timely manner. People with diabetes are different. If you eat too much watermelon in a short period of time, not only will your blood sugar rise, but in severe cases, metabolic disorders may lead to acidosis, which can even be life-threatening. The amount of carbohydrates (sugar) that diabetics eat every day needs to be strictly controlled. Therefore, if you eat watermelon many times a day, you should reduce the amount of meals and flour products (carbohydrates) accordingly to avoid aggravating the condition.

　　2. People with renal insufficiency

　　Patients with renal insufficiency have a greatly reduced ability to excrete water from the body, so they often experience edema in the lower limbs or the whole body. If these patients eat too much watermelon, they will consume too much water and be unable to expel the excess water in time, resulting in excess water storage in the body and increased blood volume. This will not only aggravate edema, but also easily induce acute heart failure. Therefore, patients with renal insufficiency are advised to eat less or no watermelon.

If people with oral ulcers eat more watermelon, too much water will be expelled for the recovery of oral ulcers, which will aggravate yin deficiency and internal heat, making the course of the disease prolonged and difficult to heal.
