1. Dairy products: milk, yogurt, cheese, etc. Dairy products are rich in calcium and vitamin D, which is beneficial to bone development.

In addition, a reasonable diet is also very important. Reasonable nutrition intake will make children's growth and development healthier. Primary and secondary school students should pay attention to food collocation and try to avoid eating too much high-calorie food such as sugar and oil, so as not to affect their physical development. At the same time, a moderate, balanced and diverse diet helps children to be energetic, healthy and intellectually developed.

In addition, children should drink enough water every day, at least 8 cups a day, to help the body maintain water and metabolism.

In short, when making a diet plan for children, we need to pay attention to their preferences, tastes and food preferences, and gradually guide them to form healthy eating habits, so as to avoid letting them eat too many foods with high calorie, high fat and high sugar and ensure their healthy growth.
