Overnight meals are easy to lose nutrition. For leftovers that have not been stirred or turned over, if they are refrigerated for 24 hours and then heated, the nutrients, especially vitamins, will be destroyed, so long-term consumption will lead to malnutrition. Especially for special people, such as patients with chronic diseases such as hypertension and diabetes, it is necessary not only to prohibit the intake of leftovers in life, but also to actively carry out nutritional intervention, that is, to supplement the corresponding nutrition for the disease, which is conducive to delaying the progress of the disease, improving the quality of life and reducing the intake of drugs to a certain extent.
There is a certain basis for the statement that overnight meals cause cancer. The content of nitrite increased with the extension of food storage time.
Leaving meals for too long will lead to an increase in nitrite content. Excessive intake of nitrite will combine with amine, the decomposition product of protein in the body, to form ammonium nitrite, which is a strong carcinogen and easy to cause cancer in the digestive system. Therefore, it is better to eat less overnight meals that have been left for too long.
Can you be more nutritious after cooking overnight? Overfrying overnight meals will increase the damage and loss of nutrients and increase the content of nitrite, so it is not appropriate to over-fry overnight meals.
If we accidentally cook too much food, we should pay attention to it when storing it. It is estimated that leftovers may be left, so it is necessary to classify and cool them before cooking, which can reduce the proliferation of bacteria to some extent. The time of vegetables and bean products should not exceed 24 hours, and meat food should not exceed 48 hours. Soup is best stored in glass bowls or ceramic utensils. In the process of reheating food, we must pay attention to thorough heating, and never eat it after slightly heating, especially meat food, which can kill the virus that may breed in leftovers to a certain extent. It's not a problem to eat overnight meals occasionally, but it can't be eaten for a long time, because leftovers can't provide the necessary nutritional needs of the human body, especially for some special people, such as pregnant mothers, developing children and people with chronic basic diseases, we must ensure rich nutrition and try not to eat overnight food. For those who cook, try to master the amount of cooking and avoid leftovers.
