"Dai Fan" Note: What foods are not suitable for "Dai Fan"

Many urban white-collar workers struggle with lunch every day, and many smart people choose to bring their own meals, which are clean and hygienic, eliminating the troubles of entanglement, and can also eat the love lunch of their mothers or lovers. Why not? However, this meal is not casually brought, and many of them are exquisite, you know? Today, Bian Xiao will sum up some points for you, as well as matters needing attention when taking meals: First of all, diners should pay attention to the two links of overnight meals and microwave heating while ensuring a balanced nutrition, so as to avoid the loss of nutrients, easy spoilage and harmful substances, and make diners feel at ease. Among them, leafy vegetables, seafood, cold salad and leftover soup can't be brought. ● If the leftovers of leafy vegetables are cooked for a long time, or heated twice, the salt in leafy vegetables will produce nitrite. Nitrite can not only cause food poisoning, but also react into nitrosamines after entering the human body. Nitrosamine is a carcinogen, and long-term consumption is harmful to health. This kind of vegetables include Chinese cabbage, leek, spinach, mustard, Chinese cabbage, Chinese cabbage and other green leafy vegetables, and the nitrite in spinach far exceeds other vegetables. Fresh vegetables should be fried and eaten now. If you don't eat at noon, you can eat more for dinner. ● Seafood, such as fish, shrimp and crab, is called seafood because it is delicious only when it is fresh and vigorous. Seafood can't keep its color and taste even if it is heated by microwave oven overnight. In addition, seafood is rich in protein. When protein is stored for a long time, it is easy to denature and decompose amines, losing its proper taste, flavor and safety. If it is not good, it will lead to food poisoning. ● Cold salad is mostly made of fruits and vegetables with oil, salt, sauce and vinegar. Its taste is refreshing and sour. Because it has not been heated, it is easy to breed bacteria during processing. So even if you put it in the refrigerator for the night, it is easy to deteriorate. If you put it in a lunch box and heat it with other dishes, it will lose its original taste and affect the taste of other dishes. ● Leftover soup Many people like to drink some soup at dinner. If they can't finish it, they will put it in the refrigerator and continue to drink it after lunch the next day. Overnight leftover soup is usually put in metal utensils for storage in the refrigerator, but the salt in the soup is easy to react with the metal, which leads to the dissolution of mercaptan and other compounds in the soup, which is not good for the human body.
