Dealing with obesity often starts at childhood.
There's long been a push for healthy hot lunches in school and now it seems vending machines could be the target of new legislation.
Research is proving that laws curbing the sale of junk food and sweet drinks could play a role in slowing childhood obesity.
A study, released online Monday in The Journal Pediatrics, found that although the effects weren't huge, children gained less weight in grades 5 through 8 if they lived in states with strong laws governing snacks in schools.
Though the effects weren't huge, the study found children who started the 5th grade overweight were more likely to reach a healthy size by 8th grade if they lived in states with consistent snack food laws.
