How to deal with household leftovers correctly? A healthy diet consists in cooking and eating now. When cooking at home, there are always leftovers sometimes. Not long ago, on the microblog, some netizens spread the saying that leftovers were poisonous. Are leftovers really poisonous? In this regard, nutritionists told reporters that the treatment of leftovers depends on the situation. Generally speaking, vegetables will produce nitrite harmful to the body after overnight. Therefore, the leftover vegetables should be poured out; However, meat dishes are generally not a problem. Nutritionists suggest that to fundamentally solve the problem of leftovers, we should start with changing unreasonable eating habits.
There are two kinds of leftovers. One is to cook at noon and continue to eat at night; The other is leftovers after a night. Nutritionist Lin Junxian said, 'there are no leftovers for the night. The dishes made at noon are left to eat at night. The time is not long and there is no problem. It depends on what's left if you can keep the dishes overnight. Leftovers are divided into meat dishes and vegetables.
First of all, if it's vegetables after night, you should pay attention. Vegetables may produce harmful substances overnight. Because there is oil and salt in the fried vegetables, after a night, the vitamins in the vegetables are oxidized, which greatly increases the content of nitrite and turns into nitrite after entering the stomach. Nitrite itself is toxic and carcinogenic. Although the rise of nitrite is far from causing food safety accidents, nutritionists still suggest that cooked vegetables be poured out overnight.
Bean products and fish can be retained. Bean products and fish food do not produce nitrite overnight. It should be noted that their common trouble is that they may reproduce dangerous pathogens, such as the terrible Clostridium botulinum. This bacterium can produce 'botulinum toxin', but the toxin can be destroyed by heating above 100 ℃ for a few minutes, but it is very dangerous without heat penetration.
'Meat is the best food to keep. There is no problem overnight. The taste will not change a lot when heated again. Although some vitamins are lost, nutrients such as protein and iron can still be retained, so as not to produce harmful substances. Only when heating, there are problems that need to be paid attention to. " Lin Junxian said.
