Now more and more people are beginning to pay attention to health, and these people are becoming more and more cautious in many details. Especially in terms of the food at the entrance, many people have heard of it more or less, or read in the article in the circle of friends: every time you can’t finish the leftover dishes, you can’t eat them overnight. You can't eat the rice, which can easily bring harmful substances to the body and even cause cancer.
Many people strictly abide by the rule of not staying overnight, fearing that overnight meals will cause serious harm to the body. But there are also many people who are very frugal, afraid of wasting food, think that overnight meals are nothing, and are unwilling to throw away the leftover food.

So, which statement is true? Will eating too much overnight cause cancer? Is it harmful to the body if it is cooked into porridge overnight? Here is a brief introduction. Can
have overnight meal?
The general saying is that overnight meals contain a substance called nitrite, so overnight meals are toxic and cause cancer. Nitrate can be converted into nitrite under certain conditions. In nature, nitrate exists in plant foods, especially some leafy vegetables such as spinach, amaranth, and Chinese cabbage . Under the action of bacteria or enzymes, the nitrate in vegetables will be converted into nitrite. When nitrite reacts with gastric acid, it will produce carcinogens: nitrosamines. Although
sounds serious, it is actually only possible to cause nitrite poisoning when the intake reaches 0.2-0.5 grams, and 17 kinds of vegetables such as spinach, Chinese cabbage, cucumber, tomato , etc. have been tested and refrigerated. The nitrite content of overnight vegetables is only 1.21mg/kg, which is far lower than the national "Processed Food Safety Standard" . Therefore, eating overnight does not necessarily mean that it is toxic and carcinogenic.
Rice needs a variety of factors to produce harmful substances. As long as there is no deterioration or mold in the overnight meal, it will not easily bring harmful substances to the body, and it will not cause serious damage to health. Especially in winter, when the weather is relatively cold and the temperature is low, the rice is less prone to spoilage and mold, so there is no need to worry too much even overnight.

Green leafy vegetables are best not to eat overnight. As the enzymes in cooked vegetables are killed, the main reason for the production of nitrite in cooked vegetables is bacteria. Green leafy vegetables will breed bacteria after being left for a long time, and it is easier to produce nitrite than rice. Especially cold dishes, it is not recommended to eat them overnight. As long as it does not deteriorate, eating overnight vegetables occasionally will not harm your health once, but if you eat too much, it will definitely be harmful to your health. It is recommended to eat fresh vegetables to eat better, and the nutrition will be more comprehensive.

Of course, some overnight food is best not to eat, so as not to cause trouble to the body. It is recommended that if you want to store dishes overnight, you should pay attention to the storage location and try to put it in a low temperature location to reduce the production of harmful substances.
