How about eating more melons in summer?

Eating watermelon in summer can not only prevent heatstroke, but also remove fire. When eating watermelon, there are also some problems that need attention. First, don't eat too much, otherwise it will hurt the spleen and stomach and cause pharyngitis. Watermelon is a cold product, and eating too much is easy to hurt the spleen and stomach. Therefore, people with spleen and stomach deficiency and cold, dyspepsia and loose stool should eat less, while eating more will lead to abdominal distension, diarrhea, loss of appetite, accumulation of cold and dampness, and cause diseases. Eating too much watermelon at a time will dilute gastric juice, cause indigestion and decrease gastrointestinal resistance. Second, don't eat watermelon at the beginning of a cold, otherwise it will aggravate the cold or prolong the cure time. Both wind-cold cold and wind-heat cold belong to exterior syndrome in the early stage, so we should treat them with divergent methods to solve the pathogenic factors from the exterior. Traditional Chinese medicine believes that exterior and interior are not attacked, otherwise exterior evil will enter the interior, and the condition will be aggravated. In the early stage of a cold, eating watermelon is equivalent to eating drugs that clear away heat from the interior surface, which will lead to the entry of pathogenic factors, aggravate the cold or prolong the cure time. However, when the cold gets worse and there are fever symptoms such as high fever, thirst, sore throat and yellow urine, you can eat some watermelons while taking normal drugs, which is helpful for the recovery of the cold. Third, don't eat watermelons that have been open for too long. When the temperature is high, watermelon is easy to deteriorate after being opened for a long time, which will breed germs and lead to intestinal infectious diseases. Therefore, when eating watermelon, we should pay attention to choosing ripe fresh watermelon. Fourth, people with renal insufficiency should not eat it. Eating a lot of watermelon in a short period of time will increase the water in the body, which exceeds the physiological capacity of the human body. In patients with renal insufficiency, the ability of kidney to regulate water is greatly reduced, and too much water entering the body can not be regulated and excreted, resulting in a sharp increase in blood volume and easy death due to acute heart failure. Fifth, people with oral ulcers should not eat. Traditional Chinese medicine believes that the main causes of oral ulcers are internal heat due to yin deficiency, disturbance due to deficiency of fire, and burning flesh and blood veins. Watermelon has diuretic effect. If people with oral ulcer eat more watermelon, the water normally needed in the body will be discharged through the diuretic effect of watermelon, which will aggravate the state of insufficient vaginal fluid. Yin deficiency will increase internal heat and aggravate oral ulcer. Sixth, diabetics should eat less. The sugar content of watermelon is about 5%. If diabetics eat too much watermelon, it will also lead to high blood sugar, increased urine sugar and other consequences, and even severe ketoacidosis coma. If you eat 25-50 grams of watermelon at a time, it will have little effect on diabetics, so diabetics should pay attention to the right amount of watermelon.
