Although this year, in the winter fruit stalls can see watermelon, but Xiaobian thinks that only in this season, hot days with watermelon is the real perfect! Like "You from the Stars," Chien-Sung Yi said "How can the beer and fried chicken be less than the first snow days?"

The Chinese medicine believes that the watermelon thirst quenches the thirst, relieves heat, relieves the heat, facilitates digestion, and promotes metabolism. It is a kind of fruit that complements body and body. Not only that it also has a high medicinal value! Guam, melon and melon seeds can be used as medicine, and there is also a very image of the name of the melon skin - watermelon Cuiyi (aesthetic bar).

When it comes to eating watermelon, Xiao Bian likes to open half, and then insert a spoon to make a circle, you can dig out a hemispherical melon. It feels more comfortable than eating cool, eating arrogance, and eating as one piece. Usually buy watermelon when the fruit stalls are generally covered with plastic wrap half of the watermelon, but do not know how long to think about the summer package, always felt do not fly; and if you buy a one-time back, every time After half a meal, the remaining half is a question of how to save. It is always a worry that bacteria will grow. How should watermelon be preserved? Little friends come onlookers!
I believe the baby will say, of course, is the plastic wrap into the refrigerator! - Well, this method is indeed the only choice, but Xiao Bian to say is that the cling film is also a risk Oh!
Do not choose airtight plastic wrap
According to food safety experts, watermelons preserved with plastic wrap are worse than those without plastic wrap. This is because watermelons have bacteria and microorganisms on the surface before they cover the cling film. If the air-permeable and water-permeable functions of the cling film are not good and the temperature drops slowly, these microorganisms or bacteria will multiply faster, especially after anaerobic reaction. Food can easily spoil.
SO cling film is too thick, it will lead to food can not "breathe" to oxygen, resulting in anaerobic fermentation resulting in spoilage. It should also be noted that some people may feel that more than one layer is more likely to lock in moisture. NONONO! The actual plastic wrap not only keeps the moisture from evaporating, but also allows the carbon dioxide inside to go out. Too thick, it is not conducive to preservation. â€
Then how do you do? From now on without plastic wrap? Certainly impossible, but time must be strictly controlled, the following is more important!
Time, time, time, important things say three times
Cut watermelon into the refrigerator, the surface will still grow bacteria. Some experts explained that this is because the watermelons are contaminated with bacteria during the cutting process. Refrigeration can only inhibit the growth of bacteria and cannot freeze bacteria. In addition, watermelon is rich in glucose, fructose and other nutrients, which will provide essential raw materials for the growth and reproduction of bacteria. These bacteria often cause food poisoning and cause diarrhea. Eat healthy watermelon in summer should pay more attention to storage time.
It is best not to leave the cut watermelon in the refrigerator for more than 12 hours and not more than 24 hours. In addition, we must also pay attention to, when cutting watermelon must be cleaned in advance watermelon, knives and chopping board, watermelon is best cut now eat, eat as soon as possible covered with plastic wrap refrigerated. In addition, when you take out the watermelon in the refrigerator, you can cut off the surface of about 1 cm. Don't be afraid of waste!
Although watermelon has many benefits, but not everyone is suitable for eating more, especially the following people must pay attention!
1, renal insufficiency should not eat: patients with renal insufficiency, reduce the ability to excrete water, often appear lower limb or systemic edema. If these patients eat too much watermelon, excessive water intake and timely discharge will lead to excessive storage of water in the body, resulting in increased blood volume, which will increase edema and induce acute heart failure.
2. The cold should not be eaten at an early stage: Chinese medicine believes that whether it is a cold or a hot or cold, its initial stage is a form of evidence. And that if the attack before the table will resolve the condition will increase, and watermelon has a heat effect, so this time eating watermelon will make the cold worse or longer duration;
3, diabetic patients should not eat: watermelon is about 5% sugar, mainly vines, sugar and some fructose, eating watermelon can cause elevated blood sugar. Because normal people will promptly secrete insulin, blood sugar, urine sugar can be maintained at a normal level, and diabetic patients are different, in the short term too much watermelon, not only blood sugar, severe illness may also be due to metabolic disorders Acidosis;
4, patients with oral ulcers should not eat: Chinese medicine that patients with oral ulcers are mostly due to yin deficiency heat, virtual fire caused by inflammation. Watermelon can be diuretic, if the oral ulcer patients eat more watermelon, the water needed for the recovery of oral ulcers will be excessive discharge, thereby increasing the yin deficiency and internal heat, making the ulcer difficult to heal;
5, pregnant, maternal should not eat: pregnant women relative lack of insulin, the stability of the role of blood sugar decreased, too much intake of watermelon can cause sugar in the blood concentration is too high, adverse to health. In addition, the pregnant and maternity physique is weak, eating more cold watermelon will damage the spleen and stomach;
6, indigestion and gastrointestinal Deficiency people should not eat: watermelon is a cold food, indigestion and stomach Deficiency people eat more easily damage the spleen and stomach, abdominal distention, diarrhea, urine and other symptoms;
7. People who have just exercised: Eating watermelon immediately after exercise, especially iced watermelon, can supplement the lost water, but it is easy to stimulate the digestive tract and damage the health of the gastrointestinal tract;
8, should not eat before and after meals: because a large number of water in watermelon will dilute the digestive juice in the stomach, eating before and after meals will affect the digestion and absorption of food, but before eating a lot of watermelon will occupy the stomach Volume, so that the intake of nutrients in the meal is greatly reduced, especially for children, pregnant women and nursing mothers greater impact on health.
Nothing can be greedy for anything, and watermelon has high nutritional value and good taste. It is easy to eat too much without paying attention. When the time comes, it will actually have a bad influence on the body. It really is "choosing sesame seeds and losing watermelon!"
