Should school cafeterias serve only healthy food?

I am going to talk about food in the school. The principal question is ''Should school cafeterias serve only healthy food?'' Nowdays school cafeteries have got a heatlthy food and not healthy food. Sweets, chocolates, chips and other food of the same category are in this moment in all schools. A lot of persons think that this food is a great problem for children.

The goverment thinks that the majority of children suffer obesity for this food. For this reason the goverment wants to prohibit this food at schools have got healty food. For example: fruits, sandwiches, juices, etc.

I agree with the goverment some features for example, schools should have got other food like chocolate or sweets because student should have varied food , because they can select their own food, but this food is not good.
