First of all, to preserve health, one should pay attention to the diet. Food affects both physical and mental health. It is not for nothing that they say: "You are what you eat."
Eat healthy and homemade food, do not overeat. This is especially true for children. In connection with rapid growth and development, the intensity of metabolic processes, and high motor activity, children need more calories than adults. The diet of a junior high school student should be rich in vitamins and minerals, including trace elements (potassium, sodium, calcium, phosphorus, iron). It is necessary to adhere to a strict diet, which may change slightly depending on the shift in which the student studies. Breakfast and lunch should be the most caloric, rich in protein, and dinner should be mainly dairy and vegetable food, porridge.
