Can eating watermelon reduce internal heat? Can eating watermelon reduce internal heat?

People tend to be more irritable and have a lot of temper in summer. Many people believe that eating watermelon can reduce heat. So, can watermelon really reduce heat?

Watermelon is diuretic but not laxative

For example, if you put a piece of fresh radish in very concentrated salt water, the radish will wilt after a long time. Why? Because the salt water extracts the water in the radish, which is the high osmotic property of salt water. Sugar and salt have the same osmotic property. Watermelon has a high sugar content, and some people have poor sugar absorption function, especially after eating too much, this high osmotic condition will form in the body: the ability of cells to absorb water is less than this osmotic pressure, and the water in the food and cells will be precipitated and excreted from the body, resulting in osmotic diarrhea.

This situation can also occur in the urinary system, which is the reason why watermelon is an osmotic diuretic. As for the occurrence of constipation, the medical professor believes that watermelon is a diuretic but not a bowel-moistening food. After eating too much watermelon, the water in the body is excreted through urine, and the water entering the intestine is relatively less. In addition, due to the influence of mental factors and low intake of dietary fiber, it is not difficult to understand why some people have dry stools or even constipation.

It is best not to eat watermelon that has been refrigerated.

Eating cold watermelon will damage your spleen and stomach - before eating watermelon in summer, many people like to put it in the refrigerator and eat it after it is cold. Although this makes your mouth feel comfortable, it will cause great harm to your spleen, stomach and throat.

Generally speaking, for people with normal gastrointestinal function, eating more watermelon will not cause constipation or diarrhea. However, there are many people suffering from various gastrointestinal inflammations in life. In addition to mental factors such as work stress and irregular life, there are also many people suffering from irritable bowel syndrome. Director Yu Guixiang said that constipation or diarrhea after eating more watermelon often occurs in the above-mentioned group of people, because the high permeability of watermelon can easily cause changes in gastrointestinal function dynamics in this group of people. It can be seen that "constipation and diarrhea" are not caused by watermelon, but "poor gastrointestinal function" first, and "constipation and diarrhea" later. Therefore, for watermelon, it is best for this type of people to eat less or no watermelon, or eat it in several times. It is best not to eat watermelon that has been refrigerated.
