Should Junk Food be Banned From School?

No I don’t think that junk food should be banned from school because we all need some fat and salt in our body to keep us alive. If it was gone then people wouldn’t get all the fat and salt that they need in there body. The school needs junk food because people like to eat junk food after their meal. If there was ony healthy food people wouldn't get as much and then they won't like to eat the school lunches. But they should still get some healthy food.
