Introduction: Heating food can make it easier to absorb but also destroyed part of the food nutrition, and repeated heating is more likely to make food carcinogenic, so do namely eat, do not eat or carefully eat overnight rice, return to the pot is a good habit.
Ancient and modern gleanings: related records in ancient books said residue food cannot be sacrificed to ancestors. During that period, to eat clean food, the ancient people cooked fresh food for each meal. However, modern people often cook a meal to eat several times and ignore the principle of fresh diet.
Beware of overnight meals.
Before the popularity of refrigerators, people often preserved food by curing or smoking, and such food contains a large number of nitrates and nitrites, in the stomach, these foods can be converted into carcinogenic n-nitroso compounds, the popularity of refrigerators and the correct use of it reduced the incidence of cancer. But with the popularity of the refrigerator, residents eat overnight dishes and return the probability of pot dishes also increased correspondingly, because the work and life rhythm are generally accelerated, could not leave the refrigerator in the four seasons, take food stored in the refrigerator for long-term, increased the probability of bacteria hurt the stomach.
✵Form good habits:
The first cooking habit is how much you eat and how much you cook. If you are really busy, or afraid of no more time, or because you have to take a box lunch to work the next day, you have to eat back to the pot, then you better choose the materials, the food could be reheated are rice, beef, soy products, a variety of non-green leafy vegetables, such as towel gourd, lotus root, celery, mushrooms, radish, etc. Sauteed vegetables should be fried until nearly cooked, to prevent further damage to their nutritional content when microwaved the next day. To choose meat dishes better choose less fat as far as possible, such as beef, chicken and so on. If not eaten, it can be immediately stored in a 4 ℃ refrigerator. Put it in the refrigerator immediately after you bring it to the office the next day. Never eat overnight food such as fish, seafood, green leafy vegetables, coleslaw, etc. Put remaining soup and dish a long time in an aluminum pot, stainless steel pot, easily happen biochemical reactions, the better is to place them in glass or ceramic vessels. If you're cooking in a large pot, use a clean spoon each time you scoop so you don't introduce more bacteria to the food. The rest of the meat dishes can be rinsed off before being preserved and reprocessed to reduce toxins the next time they need to be cooked.
✵There are two major factors turn nitrate to nitrite: one is bacteria, and another is temperature. So overnight dishes can be eaten if handled carefully. Add with a little pork skin when stir-fry, equivalent to frying some lard in the pot, and pack the rest of the dishes immediately with plastic film sealed and store in the 0 ℃ insulation layer of the refrigerator, so that the dishes will be soon frozen. Take any last night food out of the refrigerator and observe it. Smell it carefully to see if the smell has changed. Make sure there is no problem before continuing to heat the food and take it. Food stored in the refrigerator should be eaten as soon as possible.
Health benefits.
✵1. Fresh and nutritious: ready-to-eat meals allow you to eat foods that are less nutritionally compromised. The longer you leave it, the more nutrients you'll lose and the bacteria will grow, so it's better to eat as you cooked.
✵2. Disease prevention and cancer prevention: for those green vegetables, spinach and other green vegetables, green beans, cowpea, broad bean, and other green beans, repeatedly return to the pot, the content chlorophyll of these vegetables is prone to biochemical reaction, produce degradable components, easy to cause cancer. Different amounts of nitrates are found in various leafy green vegetables. Nitrates are not toxic, but they can be reduced to toxic nitrites by bacteria during the picking, transportation, storage, and cooking of vegetables. Overnight leftovers, in particular, have higher nitrite levels after being salted overnight. Nitrites, when heated, can become more toxic and can lead to food poisoning. The gastric cancer rate in some areas has shown a trend of younger age, which is related to the large consumption of overnight dishes and returned dishes.
✵3. Liver and kidney protection: crab, fish, shrimp and other seafood, once stored overnight, easy to produce protein degradation, will damage the liver, kidney, but eat freshly cooked food can avoid these potential problems.
✵Tips: Take meal office worker, can take a few clean fruits and vegetables that can eat raw, to make up for the regret that cannot eat ripe green leafy vegetables.
