Can I eat overnight dishes?

You can eat overnight dishes, but try to eat less.

According to scientific determination, overnight vegetables contain more nitrate. After long-term storage, overnight vegetables are not only destroyed in nutritional value, but also reduced to pathogenic nitrite under the decomposition of bacteria, which has carcinogenic effect and cannot be removed even if heated. So overnight dishes are not suitable for eating if they are left for a long time.

Some people think that it is understandable to sterilize the dishes that have just been cooked, but it is more conducive to the reproduction of bacteria if the dishes are left in the air for a long time overnight. Therefore, overnight dishes in summer should be kept in the refrigerator, which is conducive to inhibiting the proliferation of bacteria. In addition, overnight dishes should be kept in the refrigerator in winter. Although there is a refrigerator to protect it, it is not appropriate to preserve overnight dishes. The conditions of bacterial reproduction and overnight dishes are contaminated by bacteria, which is harmful to human health.

Fried vegetables have oxidized half the vitamins in vegetables. However, after overnight storage, the vitamins in vegetables have basically been oxidized, which greatly increases the content of nitrite and becomes nitrite after entering the stomach. Nitrite is easy to induce gastric cancer. So, try to finish the food of the day. If you don't eat it, keep it fresh in the refrigerator, especially in summer. High temperature will accelerate the reproduction of bacteria and lead to food deterioration. So for the sake of your health, try not to eat overnight dishes.

The harm of overnight meals

1, Production of deadly nitrite: Some overnight dishes will produce pathogenic nitrite. However, the nitrite content of overnight dishes will be determined according to the temperature and storage time, so overnight dishes should be kept in the refrigerator.

2, easy to be infected by bacteria: although food is cooked by heating, there will be bacteria. If you put overnight meals in the air, bacteria will multiply. People eat overnight meals again, which is equivalent to eating bacteria and endangering their health.

3. Decline in nutritional value: With the passage of time, the nutritional value of cooked food began to decline. Especially vitamin C in meals is the most afraid of heat, but the hotter it is, the less it is. If the food is heated repeatedly, the content of vitamin C will be gradually lost, so eating overnight meals can not supplement the nutrients needed by the human body.

4, induce various diseases: food contains nitrite, if nitrite enters the human stomach, under certain circumstances, it will gradually transform into NC(N- nitroso compound), which is one of the factors that induce gastric cancer. Especially when the weather is hot, overnight meals are easy to deteriorate, and bacteria will multiply in large numbers at high temperature, which will easily lead to gastroenteritis and food poisoning.
