What happens if you eat too much watermelon?
In the hot summer, watermelon is deeply loved as a saint with a water content of up to 92%. But few people notice that the sweet temptation of this red flesh and green clothes hides health risks. Based on medical research data, this article provides an in-depth analysis of the four major health problems that may be caused by excessive consumption of watermelon. The core harm of excessive watermelon reflects the weight crisis of excessive sugar content per 500g of watermelon, which is close to the calories of half a bowl of rice. When the intake exceeds 1000g in a single day, the fructose conversion rate will exceed the (GAN-ZHANG) metabolic capacity. Studies have shown that excessive consumption for 3 consecutive days can lead to the accumulation of visceral fat. Diabetic patients should pay more attention to the fact that the GI value of watermelon is as high as 72, far exceeding that of apples (36) and other fruits. The traditional Chinese medicine theory of gastrointestinal damage stimulated by cold points out that watermelon belongs to the cold. For every 5 ° C decrease in temperature after refrigeration, the activity of digestive enzymes decreases by 30%. Clinical data shows that 30% of acute gastroenteritis in summer emergency departments are related to excessive consumption of iced watermelon. It is recommended to control the single consumption at 200-300g and leave it at room temperature for 30 minutes before eating. Oral problems with nutritional imbalance The vitamin C content of watermelon is only 1/10 of citrus, and excessive consumption will dilute the concentration of saliva enzymes. Research by the Australia Dental Society has confirmed that the incidence of oral ulcers in people who consume more than 800 grams of watermelon per day is 47% higher than normal. It is recommended to use it with vitamin C fruits such as kiwifruit to balance nutrition. Risk of excessive diuretic dehydration The citrulline contained in watermelon has a powerful diuretic effect, producing 800ml of urine per 500g of watermelon. Cardiovascular patients need special attention. Johns Hopkins University research shows that excessive consumption of watermelon can cause blood pressure to fluctuate by up to 20mmHg. It is recommended to supplement 100ml of light salt water every hour after consumption.
Watermelon is a typical representative of the homology of medicine and food. The Compendium of Materia Medica records that it "eliminates trouble and quenches thirst and relieves summer heat." Modern nutrition recommends that adults should control their daily consumption within 500g, and special groups should follow medical advice. Only by reasonable collocation and scientific consumption can the health value of watermelon be truly exerted.
