The latest debate over childhood obesity involves a possible ban on chocolate milk in some U.S. schools.
Proponents of the law argue that flavored milks contain high amounts of sugar, some as much as an eight-ounce can of soda.
"Chocolate milk is soda in drag," said Ann Cooper, director of nutrition services for the Boulder Valley School District in Louisville, Colo., which has banned flavored milk.
"It works as a treat in homes, but it doesn't belong in schools," she said.
But many nutritionists warn against such laws, noting that even flavored milk contains nine essential nutrients, like calcium and vitamin D.
Several groups -- including the School Nutrition Association, American Academy of Pediatrics, American Dietetic Association, American Heart Association, and National Medical Association -- have already released a joint statement in support of such beverages.
The statement pointed out that studies show that children who drink fat-free, flavored milk are no heavier than those don't drink milk.
John Deasy, the superintendent of Los Angeles Unified, the second-largest school district in the country, announced he'll be pushing the ban this summer. Other school systems have backed off the idea.
