Is it harmful to your health to eat overnight meals every day? Sometimes people will eat some lettuce yesterday to save trouble and not cook, but you know how harmful it is to eat leftovers! Some foods will produce a lot of harmful substances when they are cold. Usually, many office workers will choose to cook at night and bring it directly to the company tomorrow, and prepare one in advance at noon in the morning, which is what we call overnight dishes! However, overnight cooking is very harmful to our health. We should cook now in the morning. If it is too late, even if we have an overnight meal, there will be a lot of pressure. Eating overnight vegetables will make most of the nutrients in the vegetables we eat lose. Vitamin C, chlorophyll and these nutrients are very important to human health. If VC has been lost once after high-temperature heating, and the nutrients will continue to be lost when these dishes are heated the next day, then the nutrients will be even lower, and the nutrients of overnight food are far less than those of just-cooked food! Moreover, eating for a long time will produce a kind of nitrite. Nitrite is one of carcinogens, and nitrite hydrochloric acid can be determined as a carcinogen when it accumulates to a certain extent! If you really want to eat overnight vegetables, you can avoid some leafy vegetables, because leafy vegetables contain more nitrite hydrochloric acid, so you should pay attention to the low preservation of cooked food. The nitrite in overnight dishes also increased obviously at 25 degrees Celsius, so our dishes can reduce the nitrite production if they are suitable for low temperature. Our food should be stored separately to avoid unnecessary bacteria. Because of its nutritional value, we should try to eat less overnight dishes. We must eat less. If we eat hot dishes, we must heat them to eliminate microorganisms in the food! Only a small amount is eaten, but if you often eat overnight dishes, it will definitely be harmful to your health.
