USDA Secretary Tom Vilsack, together with First Lady Michelle Obama, announced improved nutrition standards for school meals on January 25, 2012. The new requirements, part of the Healthy, Hunger-Free Kids Act, are the first updates to make school breakfasts and lunches healthier in more than 15 years. "USDA built the new [guidelines] around recommendations from a panel of experts convened by the Institute of Medicine — a gold standard for evidence-based health analysis," the USDA said in its press release. Beginning July 2012, meals served in schools will include fruits and vegetables daily, more whole grains, fat-free or low-fat milk, and less saturated fat, trans fat, and sodium. Meals must fall between calorie minimums and maximums based on children's ages. All of these changes are in line with the IOM report School Meals: Building Blocks for Healthy Children.
