Xiao Guo works in a private company. Although the company is adjacent to a food street, exquisite Xiaoguo insists on eating meals brought from home at noon every day. There are not a few young people who are so frugal and environmentally friendly now. But as we know, office workers usually cook meals the night before, put them in the refrigerator and heat them in the microwave at noon the next day. The microwave oven has become the fastest treasure chest. How to use it conveniently without taking in too much nutrition in food? How big is the nutritional loss of microwave food? It has been widely rumored that microwave food loses huge nutrition, which is harmful to health and easy to cause cancer. However, this statement was later proved to be a fallacy. Experts come to the conclusion that microwave heating food, although more or less will make the nutrition in food lose a little, is not so exaggerated and absolute. And when heating sweet potatoes and other foods, its nutrient loss components are far lower than traditional cooking methods. It seems that the nutrient loss of microwave food cannot be generalized, more or less depends on how you use the microwave oven. Microwave heating food is a freshman. Remember to keep moisture when heating the food. Friends who have used microwave ovens to heat meals for a long time should have a deep understanding of this. A slightly drier meal will only look drier when it is heated in the microwave oven. Yes, microwave ovens rely on the high-speed vibration of polar water molecules to increase the kinetic energy of molecules and raise the temperature. Therefore, when heating meals in the microwave oven, you must remember to keep moisture. The following two tricks teach you to easily prevent water loss: 1. Cover the bowl tightly before heating the food. If there is no bowl cover, wrap it with plastic wrap instead. 2. If your taste buds are not so picky, when heating rice, cakes or dishes, sprinkle some water on the surface and put it in the microwave oven. In this way, even if the microwave absorbs a certain amount of water, the remaining water still exists in the food. Some foods lose less nutrition when heated by microwave than traditional cooking methods, so this kind of food is very suitable for microwave. However, some foods are not optimistic after being heated in the microwave oven. The following small series lists several foods that are not suitable for microwave ovens: 1. Don't cook raw eggs with shells and eggs with shells, otherwise the cooked eggs are very unsuitable for microwave heating. Let's not talk about the loss of nutrition. If eggs with shells or broken yolk are heated by microwave oven, it is easy to damage the microwave oven and even explode seriously, hurting people and themselves, and the consequences are unimaginable. 2. Fried and stir-fried foods are not suitable for microwave heating. Because this food has lost a lot of water in traditional cooking. If you "heat" in the microwave for a few more minutes, it will only "make matters worse" and there is no nutrition at all.
