Why eating in classroom should not be banned?

because a lot of students can't eat at home because of they most of the time have reckless parents who do drugs and other things like that so they have to wait till lunch but they won't be able to concentrate on their work so they will make terrible grades just because a teacher or a principal doesn't want ¨distractions¨ in the classroom.

Some students may not be able to have breakfast, if they are late, don't have any food at home, or even abusive parents. They wouldn't be able to eat until lunch, and for some lunch is as late as 1:30. Even students who do have the privilege of eating breakfast at home may have a hard time waiting this long.
