Watermelon can be said to be a delicious fruit that runs through summer and autumn. Even though it's already autumn, there are still many people who sit by the air conditioning and eat watermelon. But you know what? That sweet melon that touches the heart may hide a 'sweet assassin'. Some people transform into "jet warriors" after eating, some experience a rollercoaster ride on their blood sugar levels, and some become more and more "overheated" as they eat... Today, the doctor will take you to eat melons scientifically, allowing you to have delicious and healthy food at the same time! The high sweetness warning of watermelon: excessive consumption increases metabolic burden. The sweetness in watermelon mainly comes from fructose. Although fructose does not require the involvement of insulin in the metabolic process, excessive intake can increase the metabolic burden on the liver and produce a large amount of uric acid. Long term excessive intake of fructose may increase the risk of hyperuricemia and gout. The glycemic index (GI) of watermelon, which causes a surge in blood sugar, is about 72, making it a medium to high GI food. For patients with diabetes or those who need blood sugar control, too sweet watermelon may increase blood sugar rapidly, which is not conducive to stable blood sugar control. Sweetness ≠ high nutritional value. The nutritional value of watermelon depends not only on its sweetness, but also on its moisture, vitamins, minerals, and other nutritional components. So, although watermelon is delicious, it should not be flashy. To prevent eating melons from becoming a 'sweet burden'. According to the recommendations of the "Chinese Dietary Guidelines for Residents (2022)", adults should limit their daily fruit intake to 200-350 grams (approximately 1-2 small bowls of chopped fruit). Due to the high moisture content of watermelon (about 90%), it can be appropriately relaxed to 300-500 grams (about 2-3 slices of regular sized watermelon). In addition, excessive consumption of watermelon may occupy stomach space, leading to a decrease in the intake of other foods, thereby affecting the intake of nutrients such as protein and fat, resulting in nutritional imbalance. The calorie intake of watermelon for weight loss individuals is approximately 27 calories per 100 grams, but they may accidentally consume half of it - close to 500 grams. Based on an 8% sugar content, this is equivalent to consuming about 40 grams of sugar, and the calories are equivalent to a small bowl of rice. Therefore, controlling the amount of melons is important. Diabetes patients should be controlled at 100-150g/day, eat in batches, and detect blood sugar. You can choose to consume between meals to avoid excessive blood sugar fluctuations. If blood sugar control is unstable, it's better to put down the watermelon in your hand. Patients with renal insufficiency need to limit potassium intake, and it is recommended to limit it to less than 100g/day. Watermelon contains approximately 112mg of potassium per 100g. Overconsumption can increase the burden on the kidneys or cause difficulty in potassium excretion, leading to edema or elevated blood potassium levels. Pregnant women and children can consume it normally, but avoid refrigerated consumption to prevent gastrointestinal irritation. Protecting gastrointestinal safety: Eating melons and watermelons is a cold food, and excessive consumption by those with spleen and stomach deficiency cold, middle burner cold and dampness may lead to discomfort symptoms such as abdominal pain and diarrhea. Excessive consumption of melons by individuals with yin deficiency and excessive fire may lead to excessive urine excretion, which can easily cause loss of body fluids and even lead to symptoms such as oral ulcers. In addition, the sliced watermelon should be stored at low temperature as soon as possible, preferably not exceeding 12 hours. At the same time, try to avoid consuming large amounts of watermelon on an empty stomach, and do not eat it with other cold drinks. To avoid irritation to the gastrointestinal tract, it is best to consume after meals or between meals. In addition to the flesh of the watermelon, the remaining watermelon skin after removing the outermost dark green part is called the "watermelon green coat". Using it to boil water instead of tea can be used to treat symptoms such as heat, thirst, mouth sores, dry throat and mouth. (New Society)
