STUDY: Banning Chocolate Milk at School Is a Bad Idea Very few people would deny that the problem of childhood obesity is serious. Unfortunately, figuring out the solution to this problem has been difficult, to say the least. Health officials across the country have done some good things – but it’s an imperfect science. For example, some schools have banned chocolate milk. It makes some sense because the gunk they add to milk to make the chocolate flavor is filled with sugar. But a new study has found that keeping chocolate milk out of schools has the effect of less milk being consumed by the kids. Researchers found that students take 10 percent less milk, waste 29 percent more milk, and may even stop eating school meals. So while banning chocolate milk might reduce calorie and sugar intake, it might not be worth it in the long run.
