Not paying attention to cold dishes with balanced nutrition will lead to many problems. Cold dishes can balance the problem of excessive oil and protein in the main course. However, many people are used to ordering meat cold dishes such as sauce beef, Luohan belly and boiled chicken, which makes the cold dishes lose the function of regulating nutritional balance and aggravate the surplus in protein. In addition, cold meat is easy to breed bacteria and cause diarrhea and other problems.

The more natural the cold salad, the better. An Jianhua, a nutritionist at the Nutrition Research Center of Beijing Normal University, said that vitamins are water-soluble substances, and it is easy to lose vitamins when vegetables are blanched. She reminded people that eating raw food in summer is easy to breed bacteria and cause intestinal diseases, so raw food must be hygienic and washed before eating. Garlic and vinegar have bactericidal effect. It is suggested to add vinegar and garlic to the cold salad, which can both flavor and sterilize, but those with excessive gastric acid secretion should try not to add it.
