But not all food can be eaten overnight. 1.Can I eat overnight silver fungus? Silver fungus soup is an advanced nutritional tonic, but once it is overnight, the nutrients will be reduced and harmful ingredients will be produced. Because both indoor cultivated silver fungus and linden cultivated silver fungus in the field contain more nitrates, after being cooked for a long time, the nitrates will be reduced to nitrite by the decomposition of bacteria. People drink this soup, nitrite will naturally enter the blood circulation, blood in the red blood cells have hemoglobin, can carry a large amount of oxygen for the body needs. But nitrite acts in the opposite direction, so that the body’s normal hemoglobin oxidation into high iron hemoglobin, the loss of the ability to carry oxygen, resulting in the lack of normal hematopoietic function of the body! 2, overnight tea can not drink overnight tea because of the time, most of the vitamins have been lost, and tea soup in the protein, sugar, etc. will become bacteria, mold breeding nutrients, so people usually think that overnight tea can not drink. 3, overnight boiling water can not drink? Boil the tap water for 3 to 5 minutes, the content of nitrite and chloride and other harmful substances is the lowest, the most suitable for people to drink. Drink less overnight boiled water: nitrite in the body can form carcinogenic nitrosamines. Some experts found that the nitrite content in boiled water is higher than raw water. And repeatedly boiled for too long or more than 24 hours of boiling water, the content of nitrite are significantly higher. After 24 hours of boiling water, nitrite content is just boiled 1.3 times. Our residents have the habit of drinking boiled water, it is best to boil now or drink only the day of boiling water. Also do not drink boiling water boiled for too long. Not to waste food is a virtue, in order not to waste leftover food, there are many people will eat leftover food in the evening to enjoy tomorrow.

Because if the eggs are not fully cooked, uncooked egg yolk overnight after eating, in the case of improper storage, the nutritious stuff is easy to breed bacteria, so it will be harmful to health, for example: cause gastrointestinal discomfort, flatulence and other situations. But if the food (eggs) has been cooked, and low temperature (general refrigeration temperature) sealed properly, generally can be stored for 48 hours are no problem. From the scientist’s tips we can know: whether eggs can be eaten overnight, not only depends on whether it is heated, but to cook the eggs for the first time, only after the first boiled eggs cooked, cooked overnight and eaten is no problem. Tea eggs is the same reason, you may not know, tea eggs are cooked two times, the first time cooked, the second time the egg skin cracked, add tea and other auxiliary ingredients, and then cooked, so tea eggs are definitely cooked, now some people love to eat half-cooked eggs, (the yolk is semi-liquid) that kind of eggs can not eat overnight, even if the second cooked, do not eat. 5, overnight leafy vegetables do not eat! As some leafy greens contain more nitrates, cooked if left too long, under the decomposition of bacteria, nitrate will be reduced to nitrite, carcinogenic effect, heating can not be removed. Healthy eating: Usually the highest nitrate content of stem and leafy vegetables, melon vegetables are slightly lower, root vegetables and cauliflower are in the middle. Therefore, if you buy different kinds of vegetables at the same time, you should eat the stems and leaves first, such as cabbage, spinach, etc..

Fish and seafood overnight easy to produce protein degradation, will damage liver and kidney function. Green leafy vegetables contain different amounts of nitrates, overcooked or put too long, not only will the vegetables will be yellow, tasteless, nitrate will be reduced to toxic nitrite by bacteria, carcinogenic effect. Cold vegetables due to the processing of more contamination, even if refrigerated, overnight is likely to have deteriorated, should be ready to eat. 8.What about overnight soup?
