Nutritional balance:

1, to ensure that children take in an appropriate proportion of six nutrients (protein, fat, carbohydrates, vitamins, minerals and water) every day.

2 to ensure that the proportion of eight categories of food, such as grain, meat, eggs, vegetables, fruits, bean products, oil and sugar, is properly distributed.

3. All kinds of food should be matched with each other. For example, meat contains complete protein and cereal contains incomplete protein. The above two foods are eaten at the same time and complement each other.

4. When changing food varieties, you can exchange meat for meat (such as beef for pork), cereal for cereal (such as rice noodles for noodles), and all kinds of fruits and vegetables are supplied in rotation, and the meat and vegetables are properly matched.

5. Don't repeat the main and non-staple foods of each meal in one day. Non-staple food should not be repeated more than twice in a week's diet.
