You can use bean eggs instead of meat and eat more dietary fiber and vitamins. In fact, eating meat once every two days is enough. If it is too greasy, try to eat lightly. It is best to try to eat scrambled eggs with tomatoes once a day, and mix vegetables with green leafy vegetables at will. You can eat celery to supplement dietary fiber for dinner (don't eat it at noon, celery is a light-sensitive food, and it will grow spots when eaten in the sun). It's best to take some apples or oranges to school to supplement vitamins on weekends.
