Does reheating rice cause cancer? Reminder: 5 kinds of foods are not recommended to eat overnight to reduce risks

After giving birth to her child, Ms. Liu resigned and became a full-time mother at home. She usually understands that it is not easy for her husband to earn money at work. She lives very frugally, and she is reluctant to throw away any leftovers.

After eating the rest of the meal at night, I also put it in the refrigerator to continue eating, but one morning I ate the egg fried rice overnight, but I started to vomit and have diarrhea .

The doctor's examination and analysis considered it to be food poisoning, which has caused acute liver failure and kidney failure. Does that mean that overnight rice cannot be eaten?

1. Can I eat rice overnight?

Many people think that meals that are left for more than one night are overnight meals. In fact, generally speaking, meals that have been left for more than 8 hours are considered overnight meals . In fact, overnight meals generally face two major safety hazards. On the one hand, microorganisms may multiply , causing food to deteriorate. On the other hand, the increase in nitrite may lead to food poisoning and increase the risk of cancer.

Previously , an experiment was done on a program of Beijing TV . The researchers put rice, steamed bread, root vegetables, nightshade vegetables, green vegetables, meat, braised eggplant, garlic and broccoli for 0 hours, 6 hours, 24 hours, etc. 48 hours , and then measured the nitrite content in it. It was found that rice, steamed bread, meat, etc. were placed for 48 hours, but no nitrite was detected, and nitrite was detected in several other vegetables. The higher the substance content. That being said, if it's just rice and it's in the fridge, it's still good to eat overnight.

2. Will reheating rice cause cancer?

There is also a saying: Rice stored at room temperature will breed bacteria, and bacteria will produce toxins if they are stored for a long time. If people eat them, they may lead to food poisoning . Reheating cannot eliminate toxins, and it may cause cancer. Is this really true?

It is true that when rice is placed at room temperature, bacteria may grow. Some people think that leftovers contain nitrates. During the secondary heating process, nitrates may be converted into nitrites under the action of bacteria , but in fact, heating has nothing to do with the reaction of these two substances. There is also no solid evidence for carcinogenic claims.
