I remember in our high school they replaced all the soda machines with fruit drinks, the problem was it was all like hi-c kool aide which has even more sugar than soda.
In elementary school we had teachers confiscate kids lunches even some who had nutritional diets, the schools served pizza hut, greasy peperoni pizza, fries, rib sandwiches, you name it. There was nothing healthy about the food served in our school.
