During his first two weeks of sports camp, my seven year-old son has been introduced to several brands of potato chips, Skittles, Twix bars, and Sour Patch Extreme (which he explained were “so sour that they make your brain smarter”). In many cases, these summer camp snack bars merely provide a continuation of the education kids get from the cafeterias and vending machines at their schools. But that could soon change. Don’t expect to find bags of organic kale and quinoa in your kids’ backpack, but the Feds have just overhauled the nutritional standards for school snacks for the first time in about thirty years.
