Should government expose restrictions on what kinds of foods can be served in a school cafeteria?

My personal opinion: yes, I believe there should be restrictions to certain foods that we let our kids eat at school.

School is meant to be a place of education, including teaching kids and teens about how to maintain a healthy diet and exercise routine (what parents let their kids eat and do at home is their business) That should be the responsibility for the PE teachers and the cooks that are feeding the kids in the cafeteria.

FACT:
"the size for the average MCdonalds kids meal is actually how much adults should be eating".
