Healthy nutrition, first of all, nutrition systematic. It is very important to stick to three meals a day, try not to skip meals. Many schoolchildren skip breakfast before classes, which, of course, is very harmful. The body needs to stock up on energy and calories before a day of work or study. It is necessary to try to limit the consumption of sweet pastries, which are often bought by schoolchildren in the cafeteria. Instead, you can take a banana, apple or nuts to school with you. It is a mistake to eat only once, for example in the evening. This way of eating is very harmful, besides, it will not allow the body to fully rest at night.
In spring, special attention should be paid to the intake of vitamins, because their amount at this time of year in berries, fruits and vegetables is reduced. In summer, you should try to make full use of the gifts that nature gives us. You can make salads of vegetables, cocktails and morsels of fresh fruit.
A healthy and nutritious diet should be made a daily habit. It will give energy and strength to study well, do sports and favorite hobbies.
P.S. I leave my photo as an example that it is necessary to follow health at any age.
