The following are taboos when eating watermelon:
1. Avoid eating too much
Watermelon is cold and rich in water. Normal healthy people should not eat too much at one time or a large amount for a long time, otherwise a lot of water in the stomach will dilute the gastric juice, causing indigestion or diarrhea. It is best to eat no more than 200 grams of watermelon at a time.
2. Avoid eating directly after being cold
If the watermelon is too cold after being refrigerated or frozen, if it is not placed at room temperature but eaten directly, it is easy to experience symptoms such as diarrhea and abdominal pain. It is recommended to put the cold watermelon aside before eating. For those with tooth allergies who have cavities and feel sore teeth after exposure to cold, as well as those with poor gastrointestinal function, it is not advisable to eat iced watermelon.
3. Diabetic patients can not eat
Watermelon contains a lot of sugar, and people with diabetes should consume it with caution. Because it may lead to an increase in blood sugar in the body, and even cause metabolic disorders, which may be life-threatening.
How long can watermelon be kept in the refrigerator before eating?
If stored properly, it should not be eaten for more than 24 hours. After the watermelon is cut, it should be wrapped with a layer of food-grade plastic wrap, which can not only prevent the watermelon from being stained with the smell of other foods in the refrigerator, but also prevent the watermelon from breeding more bacteria and other harmful substances. But this kind of refrigeration can only delay the speed of watermelon spoilage to a certain extent, and it can be kept fresh for about 24 hours. Once more than 24 hours, the watermelon will gradually deteriorate and it is recommended not to eat it.
