Students: Better Eating

Schools are urging the foods being served in the cafeteria to contain more wheats, veggies, and foods with less calories. Now I have two feelings towards this idea: it would be a good idea, and then it could not be.
The reason why I think this is a good idea is because when schools contain foods of a better value to the students, it can encourage them to eat the better foods, and it will possibly reduced the obesity rate over some time. One by one more people will go for the healthier foods, and when friends see other friends get the healthier foods, they'll want to go for it too.
But on the other hand, the reason why I don't think this idea will be very effective, is because no matter what food a school will serve, and the strides they take to better their foods, it all depends on the student. If the student doesn't go for the healthier food, what good does it make? You can't force someone to eat better, they have to do it on their own. I know myself, yeah my school has salads, and deli sandwiches on wheat bread, but I barely get those. I eat the salads sometimes but I go for the cheese pizza almost everyday. So it is all up to the individual whether or not they want to better their eating and shift to a more healthier way.
