First of all, we should know that the ingredients in the school canteen are provided by the canteen workers themselves, not by the canteen owner. They are only responsible for cleaning, cutting and putting food into the storage room. Most of the ingredients in the school come from rural families, so they are also particular about the purchase of ingredients. For example, there is a rural primary school in my hometown, and she has certain advantages in choosing snacks for her son. Therefore, when she chooses snacks that her son likes, she rarely chooses snacks that her son doesn't like. Because her son is not interested in snacks, he often chooses snacks with more brands when choosing snacks. The food provided by workers in school canteens is generally rice and fish, which provides students with many choices.
Nowadays, many school students like to eat fish, especially some old people. In their minds, if their grandchildren like to eat some big bones, big fish and big meat every day, it is easy to make students obese, so many times students eat too much, leading to overnutrition. If the meat ingredients in the school canteen are expensive, it will lead to students' poor health. Most of these ingredients need to be bought by children themselves. Therefore, many parents think that only cooking fish in the canteen can make their children overnourished. But in fact, cooking fish is not allowed in school.
The environment of the school canteen is similar to that at home, even the small restaurant outside. Because we usually eat delicious food cooked by some snack bars, but these things need certain conditions to be made. Because these foods need to be fried at high temperature, and a lot of oil will be put into the ingredients. If these oils are not treated at high temperature, they are likely to deteriorate and are really harmful to our health. After all, fish live in the ocean, so many people will feed them with these ingredients.
