Breakfast should be nutritious. The human body is composed of seven nutrients: protein, carbohydrate, fat, water, vitamins, minerals and dietary fiber. Then we can match meals according to this rule, for example, eggs with a coarse grain bag, a glass of milk and an orange, which is a nutritious breakfast. Another example: sweet potato with millet porridge, a few vegetables with an egg. If you can't eat that much, you can add extra vitamins and nourish DHA and phospholipids in the brain to help your child improve his memory and attention. I hope it will help you.
