In the summer, everyone likes to eat with an iced watermelon, the kind of comfort makes people shout 'Cool!'. Watermelon is the first choice as a summer fruit. Naturally, its effects of clearing away heat and relieving heat, detoxification and diuresis need not be said. However, as the saying goes: 'A coin has two sidesFirst of all, many friends are used to eating watermelon before or after meals, but this is actually unreasonable. A large amount of water in watermelon dilutes the gastric juice, affecting the digestion and absorption of food, and eating watermelon before meals will occupy a large amount of stomach volume, which greatly reduces the various nutrients in the meal, especially for children and pregnant women. For those who need to diet to lose weight, eating watermelon before meals is a good way to reduce food intake. Furthermore, people with diabetes cannot eat more watermelon. Watermelon contains 5% carbohydrates, and is mainly glucose, sucrose and some fructose. Diabetics should not eat too much watermelon every day, otherwise blood sugar will rise, causing metabolic disorders and causing acidosis and even life-threatening. If people with diabetes want to eat watermelon, they also need to strictly control their intake. Under normal circumstances, daily carbohydrates need to be controlled according to the amount. If watermelon is eaten that day, the number of meals and noodles should be reduced accordingly. Finally, watermelon is a cold food, easy to damage the spleen and stomach. If a normal healthy person eats too much, the water in the watermelon will dilute the gastric juice, causing indigestion or diarrhea. In addition, watermelon must not be eaten after it has deteriorated, otherwise it will cause gastrointestinal cold accumulation and diarrhea.
