Nutrition directors in Hall County and Gainesville school districts said a proclamation by newly appointed U.S. Secretary of Agriculture Sonny Perdue slowing the pace of upcoming regulations designed to make school meals more nutritious will help schools eventually be able to meet the requirements. Perdue, a former Georgia governor, signed the proclamation this week delaying an upcoming requirement to lower the amount of sodium in meals while continuing to allow waivers for regulations that all grains in school lunches must be 51 percent whole grain. It also allows schools to serve 1 percent flavored milk instead of nonfat milk that was required under rules set during the Obama administration.
