1, food diversification. First of all, in the process of preparing food, the primary school custody class should prepare a variety of foods, and to meet all the nutrients needed by the human body, it is necessary to ensure the diversity of foods. At least 4-7 nutritious food groups should be guaranteed in the daily menu, which cannot be repeated every day.

2. Balance all kinds of food. Different foods have different nutrients, and the body has a requirement for various nutrients. It is not good to eat too much or too little. In the process of making nutrition recipes for primary school nursing classes, we should pay attention to the proportion of food collocation, and also pay attention to the collocation of the same group of food, such as thick and thin collocation, deep and shallow vegetable collocation, fish and poultry collocation and so on.

3. Eat on time. Three meals a day conforms to the physiological characteristics of human digestive system. If you eat more snacks between meals, it will affect your dinner intake. Some students often buy roadside stalls, most of which have single ingredients and food hygiene problems. To solve this phenomenon, the custody class needs to communicate with parents.

4. Quiet dining environment. Trusteeship classes should help children to establish a quiet dining environment, cultivate their eating habits of chewing slowly, and properly match soothing music, which is conducive to children's happy mood. The dining table is not a place to correct children's bad eating habits. It is necessary to strengthen the usual education instead of correcting children while eating.
