Family Life Knows Everything.

Chapter 94
In daily life, people often put the leftover meals in the refrigerator and eat them after reheating the next meal, thinking that this can prevent waste and prevent food poisoning.In fact, from a medical point of view, this view is not entirely correct.Because some food toxins cannot be eliminated by heating alone.Under normal circumstances, certain bacteria, viruses and parasites can be killed in a few minutes by heating at a high temperature of 100°C.But heat doesn't do much for the chemical toxins released by bacteria in food.Heating not only fails to destroy the toxin, but sometimes increases its concentration.In addition, various green leafy vegetables contain different amounts of nitrates.Nitrate is non-toxic, but during the picking, transportation, storage, and cooking of vegetables, nitrate will be reduced to toxic nitrite by bacteria.Especially overnight leftovers, after a night of salting, the content of nitrite will be higher.However, when nitrite is heated, its toxicity will increase, and in severe cases it can lead to food poisoning and even death.In addition, solanin contained in germinated potatoes and aflatoxin contained in moldy peanuts cannot be destroyed by heating.Therefore, we must not think that leftovers only need to be heated, and it is best to eat as much as possible.

family life made easy

Starchy foods, such as rice cakes, can be stored for up to 4 hours, and if eaten for more than 4 hours, they may cause adverse reactions even if they are eaten without changing the taste.The reason is that they are easy to be parasitized by Staphylococcus, and the toxins of these bacteria will not decompose under high temperature heating, which cannot solve the problem of deterioration, so it is best to eat this kind of food within 4 hours.
