Some experts have studied the test scores of 1000 pupils in grades 3-6, and pointed out that students who eat breakfast have better grades than those who don't. And the weight and content of breakfast are also related to academic performance. Primary school students are in a critical period of growth and development. Skipping breakfast can easily lead to nutritional deficiency, which may lead to brain cell "failure", obesity, stomach problems, gallstones and malnutrition, and may also lead to anemia in children.

Not eating breakfast for a long time will not only lead to insufficient energy and nutrition intake throughout the day, but also cause hunger at 90: 00 in the morning, causing excessive friction on the inner wall of the intestine, damaging the intestinal mucosa, and leading to digestive system diseases and malnutrition. In this way, the immunity of the whole body will be reduced, and the resistance of the body will be greatly reduced.

"Brain function depends largely on what you eat in the morning." A survey in the United States shows that the intake of energy, protein, fat, carbohydrates and some minerals, such as calcium, iron, vitamin B2, vitamin B 12, vitamin A and folic acid, of children who skip breakfast is lower than that of children who eat breakfast. The nutrition provided by breakfast is difficult to be supplemented by lunch or dinner.

Therefore, eating breakfast plays an important role in the physical and mental health of primary school students. Therefore, primary school students should pay attention to breakfast, not only to eat enough but also to eat well.
