Battling the bulge

The NY Times takes a look at the many ways underway -- and Arkansas is mentioned -- to encourage healthier eating and living by children to reduce the number of fat kids. But, there's this:

But there is one big shadow over all this healthy enthusiasm: no one can prove that it works. For all the menus being defatted, salad bars made organic and vending machines being banned, no one can prove that changes in school lunches will make our children lose weight. True, studies show that students who exercise more and have healthier diets learn better and fidget less, and that alone would be a worthwhile goal. But if the main reason for overhauling the cafeteria is to reverse the epidemic of obesity and the lifelong health problems that result, then shouldn’t we be able to prove we are doing what we set out to do?

The smattering of controlled prevention studies in the scientific literature have decidedly mixed findings. “There just isn’t definitive proof,” says Benjamin Caballero, the principal investigator on the largest study, of 1,704 students over three years in the 1990’s, which showed no change in the body-mass index of those whose schools had spent $20 million changing their menus, exercise programs and nutritional education. A second study, of more than 5,000 students undertaken at about the same time, came to similar conclusions. “There are a few smaller studies with more promising results,” Caballero went on to say, “but right now we can’t scientifically say that all the things that should work — by that I mean improving diet, classroom nutrition education, physical activity, parental involvement — actually do work.”
