Should junk food be banned from high school vending machines?

Yes I think junk food should be banned from high school vending machines because there could be a healthier ALTERNATIVE other than that. Also PREVIOUS studies show that obesity is very common in teens and I'm sure the junk food in the schools are a big part of it. Even though students can go somewhere else and get the junk food it's much more easier for them to get it at school so why not? Another reason is it would be better if students were to come up with a STRATEGY to eat more healthy and junk food being available to them six hours a day is not making that any easier. Junk food is not healthy for anyone but it's okay to have it every once in a while but if the junk food is taken out of the high school vending machines I fell like students would get healthier.
