My core opinion:You can eat but eat less

Maybe sometimes because some dishes can't be left back to eat the next day, but this is not good. I believe that many people have heard of overnight dishes can not eat this argument. Said that overnight dishes can not eat, first of all, we have to correct a concept, the so-called overnight dishes, just more intuitive statement, in fact, as long as the dishes placed more than 8 hours, are the same thing as overnight dishes. The so-called overnight dishes can not be eaten, because many dishes contain nitrates, cooked if placed for too long, in the bacterial decomposition, nitrates will be reduced to nitrites, have a carcinogenic effect. Almost all of the food cooked and placed for a long time, there will be excessive nitrite.

1, green vegetables: usually the highest nitrate content of stem and leafy vegetables, melon vegetables a little lower, root and cauliflower class in the middle. Therefore, if you buy a lot of vegetables at the same time, you should eat leafy vegetables first. For example, cabbage, spinach and so on. If you are ready to do some more dishes the next day to eat hot, you should try to do as little as possible stem and leafy vegetables, and choose melon vegetables.

2, soybean products: tofu and other soybean products contain more water, and rich in protein and other nutrients, is a good microbial culture base. If the uneaten long placed, microbes will be a large number of protein decomposition into nitrous acid, so soy products do not eat overnight.

3, gazpacho: most of the cold dishes are not made after high temperature heating, which can lead to bacteria and parasite eggs residue. And some germs can reproduce in the low temperature of the refrigerator freezer, germs can cause intestinal diseases. Therefore, it is best to do coleslaw in moderation, do now eat, the remaining coleslaw must be poured.

4, seafood: crab, fish, shrimp and other aquatic products, overnight will produce protein degradation, damage to liver and kidney function. If you buy more, you can only cook part, the rest of the seafood with a plastic bag or plastic box, into the refrigerator frozen, next time to cook.

5, mushrooms: whether it is wild or cultivated psyllium, mushrooms, etc., are prone to residual many nitrates. If you put the time is really a little long, you can only bear to throw away.

6, overnight boiled water or long boiled water: although boiled water has been boiled through, but it is recommended to drink less overnight boiled water, because nitrites in the body can form carcinogenic nitrosamines. Some experts have found that the nitrite content in boiled water is higher than raw water. And repeated boiling time is too long or more than 24 hours of boiling water, nitrite content are significantly higher. Boiling water placed 24 hours later, the nitrite content is just boiling 1, 3 times. China's residents have the habit of drinking boiled water, it is best to boil now drink or drink only the day of the boiled water, do not drink boiling water boiling time is too long. Most of them are the danger of nitrite, the principle part of the people should also know. Blood red blood cells have hemoglobin, can carry a large amount of oxygen for the body needs, but nitrite can make the blood low iron hemoglobin oxidation into high iron hemoglobin, loss of oxygen transport function, loss of the ability to carry oxygen, resulting in the lack of normal hematopoietic function of the human body, resulting in tissue hypoxia, or death, long-term consumption of esophageal cancer, gastric cancer, liver cancer, and colorectal cancer can be caused by diseases such as adult intake of 0.2 to 0.5 grams can cause poisoning, adult intake of 0.2 to 0.5 grams can cause poisoning. 0.5 grams of adult intake can cause poisoning, 3 grams can cause death.

For your own health and environmental protection, please make sure to do every meal on demand, try to finish a meal, do not waste, do not leave it for a long time, leftovers or less fried good.
