Summer has passed, but many people still enjoy watermelon almost every day.
Eating watermelon will also bring many minor problems, such as gaining weight, such as increased blood sugar, and overnight watermelon may breed bacteria, etc.
Here I will analyze what you must know when eating watermelon.
The origin of watermelon
China is the world's largest watermelon origin , but there are different opinions on the origin of watermelon.
A saying that watermelon does not originate from China, but is produced in Africa. It was introduced in Western Regions , hence the name watermelon.
Another theory originated from the legend that Shennong tasted hundreds of herbs. According to legend, watermelon was discovered when Shennong tasted hundreds of herbs. It was originally called thin melon, which means a melon with a lot of water and sparse meat, but later it became watermelon.
The more popular view is that the native place of watermelon is in Africa. It was originally wild plant of the Cucurbitae family, and it was later artificially cultivated into edible watermelon.
As early as four thousand years ago, the Egyptians planted watermelons, and later gradually moved northward. They initially spread from the coast of Mediterranean to Northern Europe, and then went south to Middle East , India and other places. In the fourth and fifth century, they were introduced to China from the Western Regions, so it is called "watermelon".
Can overnight watermelon be eaten?
Overnight watermelon can of course be eaten, but the prerequisite is to refrigerate as soon as possible after cutting it.
can't feel the day and night changes in the refrigerator. The so-called "overnight" means that it has been left for more than 10 hours, and microorganism has enough time to proliferate. Even during the day, it is not called "overnight" from the time I wake up in the morning to sleep at night, but it has been more than ten hours, which is longer than a night of sleep.
After cutting the watermelon, leave the piece you want to eat outside, try not to chop the other parts as much as possible, the more complete the better, and then cover with clean plastic wrap as soon as possible and put it in the refrigerator to refrigerate. This is because the inside of the plant tissue is originally sterile, and bacterial contamination starts from the cut part and goes deeper into the interior. The smaller the chunks cut by , the greater the pollution.
cover plastic wrap itself will not inhibit bacterial proliferation, but is just to prevent other foods in the refrigerator from cross-contaminating on the watermelon and microorganisms on the refrigerator wall, and also to prevent various foods in the refrigerator from scenting on the watermelon.
Please remember to also raw and cooked food in the refrigerator, separate . Watermelon, a food that is directly in the mouth, must be placed as much as possible in the upper layer of the refrigerator, and do not mix it with raw fish raw meat and raw vegetables.
Those melons that don’t know when to cut are best not to store for a long time. Because they may already have a high bacterial "base", even if placed in the refrigerator, the low temperature will delay the rate of bacterial proliferation, but cannot kill a large number of bacteria that are already present, so it is not safe. Especially for the elderly, young children, patients and people with indigestion who have poor resistance, be especially careful.
Eating watermelon does have the effect of nourishing yin and clearing fire, but eating too much will promote diuresis and damage yin. Especially if you eat too much at night, it will increase your urination, which will cause frequent nighttime at night and affect sleep quality; it will increase kidney burden.
So you should pay attention to the intake in moderation of your diet. Normal people should not eat too much, otherwise it will damage the spleen and stomach and cause indigestion or diarrhea.
