Take rice, rice is the best staple food, and steamed bread, pies and other staple foods should not be brought into the box lunch. From the point of view of microwave heating, the heated rice can basically keep its original state, but steamed bread and pie are easy to dry and are not suitable for microwave heating. Try to choose beef, mutton and chicken with less unsaturated fatty acids. Pork is relatively rich in unsaturated fatty acids, so it is not suitable to be included in the box lunch category.

In addition, the nutritionist reminds you that you must pay attention to cooking methods. Cooking methods suitable for microwave heating include steaming, stewing and stewing. The dishes made by these methods are not easy to change flavor and color after microwave heating, while fried and stir-fried dishes are obviously not suitable for microwave heating. In addition, compared with green vegetables, eggplant vegetables are not easy to deteriorate, and it is not easy to change the color and fragrance of dishes after microwave heating. What needs to be reminded is that the vegetables to be brought should be fried until they are half-cooked to prevent further damage to their nutrients when heated by microwave. Classic dishes, such as scrambled eggs with tomatoes and roasted eggplant, are more suitable for "people with rice".

Since you bring rice, it is natural to consider whether the food is not easy to deteriorate and whether the color and fragrance have changed after heating in the microwave oven. The following dishes obviously can't meet the two conditions of "bringing rice". Fish and seafood are not allowed. On the one hand, fish and seafood can easily produce protein degradation products overnight, which will damage liver and kidney functions.

On the other hand, it is difficult for fish and seafood heated by microwave oven to maintain their original color and flavor, which will also affect their appetite from the appearance. It is not advisable to bring green leafy vegetables. Green leafy vegetables contain different amounts of nitrate. If heated or stored in the microwave oven for too long, vegetables will turn yellow and taste bad, and nitrate will be reduced to toxic nitrite by bacteria, which will cause cancer.

It is not appropriate to bring cold salad. The key is not to eat cold salad overnight. Cold salad is polluted during processing. Even if it is refrigerated, it is likely to deteriorate after one night. It is not advisable to put the cold salad overnight into the lunch box. In particular, it is not suitable to bring food with high oil content. Sichuan-style pork, sweet and sour pork ribs, patties and fried rice are best not to be brought, because these things are more likely to deteriorate and are not easy to keep fresh because of too much oil.
