Food nutrition science popularization - Does reheating rice cause cancer? These foods are not suitable for reheating

As a traditional virtue of the Chinese nation, I believe that many families still maintain the habit of diligence and thrift. In order not to waste food, many people will put the uneaten food in the refrigerator and reheat it for the next meal.

However

Rumor: Reheating rice can cause cancer

It has always existed

This scares many people

Many people are worried

Once the uneaten rice is reheated

It will pose a huge threat to health

Is this true?

Does reheating rice really cause cancer?

It has been said that rice will breed bacteria during storage, and the toxins produced by these bacteria cannot be eliminated even after secondary heating, and long-term intake may increase the risk of cancer. However, this view is one-sided and misleading.

In fact, any food may breed bacteria in an inappropriate storage environment. But when the food is fully reheated, most of the bacteria will be suppressed or eliminated. In addition, the causes of cancer are complex and are related to many factors such as genetics, environment, and lifestyle habits. It is too arbitrary to simply link the reheating of rice with cancer. Of course. Rice stays in a room temperature environment for a long time, and it may indeed breed some microorganisms (such as Bacillus). But these bacteria are not carcinogenic, and the most serious result after eating is diarrhea. It is recommended to pack the remaining rice in a sealed fresh-keeping box and then put it in the refrigerator; the storage time should not exceed 24 hours, and the reheated rice should be eaten within 2 hours. It is best to smell it before eating. If there is no odor or mold, you can eat it with confidence. After understanding the problem of rice, let's talk about which foods cannot be reheated.

These foods really cannot be reheated

Nowadays, many young people like to invite three or five friends to have a midnight snack after get off work, and fish, shrimp and seafood have become the new favorites on the table.

However, the dishes ordered are often not finished. In order to avoid waste, many people always store the fish, shrimp, crab and other seafood that cannot be eaten in the meal in the refrigerator and eat them after reheating.

But in fact, seafood such as fish, shrimp, and crabs have high protein content, and are prone to produce protein degradation products after being left overnight. After people eat overnight seafood, these protein degradation products will damage liver and kidney function and cause harm to human health .

Therefore, it is recommended that you cook and eat seafood immediately. If you buy too much, you can put the raw seafood in a plastic bag or box, put it in the refrigerator, and then take it out and cook it before the next consumption.
