Three meals a day are inseparable from food. It is likely that food will be left over. Most people will store food in the refrigerator. What we call overnight food? Specifically, overnight food is food that has been stored for more than 5 to 8 hours. Can we still eat food after 5~8 hours? Will certain bacteria be produced? Can we eat overnight water, overnight meat, overnight meals and overnight watermelons?
Overnight water
For convenience, some people will burn a large bucket of water in advance and put it in a pot. Sometimes, a large part of the water will be left, and this water will be drunk again. With the continuous boiling of water, the number of times to boil the water increases, and the nitrite content in the water rises slightly. If the water is kept for a long time, it is called overnight. The longer the water is kept, the higher the index of nitrite content increase. However, most of the water sources have passed the national standard, and the nitrite content in the water will not obviously exceed the standard. To some extent, there is no problem if it is stored for 24 hours. If it is properly stored, it will not affect the body if it is stored for 48 hours.
Overnight meat
The meat itself will carry some bacteria, germs and pathogens. After cooking at high temperature, the bacteria in the meat will gradually disappear, and the bacteria carried will gradually decrease. The meat is also safe. But for raw meat, it will breed a lot of bacteria and germs within a few days. If the meat is cooked, it can effectively kill the original bacteria of the meat, which is relatively safe. When you buy meat, you should buy as little as possible, and try not to store it for a long time to avoid the constant breeding and reproduction of bacteria. The meat after the overnight will not produce too many harmful substances. When you eat it, you must thoroughly heat it to reduce the breeding of some bacteria and other substances.
Overnight meal
Overnight meals are the most frequent in daily life. The food that can't be eaten is stored in the refrigerator. After being stored overnight, it becomes overnight food. Will there be some harmful products in the overnight food? Will it endanger our health? Overnight meals can be eaten normally, but we should pay more attention to eating less. If you want to eat after putting it in the refrigerator, you must fully heat it to effectively kill the bacteria in the overnight meals.
Overnight watermelon
Summer is the best time to eat watermelons. To a certain extent, it can reduce your own temperature and also replenish sufficient water for your body. Within 5 hours of storage, it can be eaten safely either in the refrigerator or outdoors, but after 5 hours, bacteria will continue to multiply. It is recommended not to eat it. After cutting, if it exceeds 16 hours, it is recommended to fully cover it with plastic wrap. If it has been stored for a long time, it is recommended that you do not eat watermelon overnight, which may easily cause abdominal pain and diarrhea.
What effect does overnight food have on the body
1. Overnight green vegetables
Generally speaking, spinach, celery and so on, which are common to us, contain very high nitrite content. If you can't eat enough and store it in the refrigerator or overnight, it will not only have no nutrition, but also produce a lot of nitrite. Eating such green leafy vegetables is easy to cause some harm to our bodies, and food poisoning is also very common.
2. Overnight seafood
Overnight seafood is very harmful to the body. For example, crabs, fish and shrimps cannot be eaten overnight. After overnight, these foods will produce certain protein degradation products, which will cause certain damage to the liver and kidney functions.
When buying seafood, you must buy as much as you eat. Don't buy a lot of seafood. After you buy it, you should try to eat it as much as possible to avoid overnight seafood.
