Healthy Eating Research (HER), a program of the Robert Wood Johnson Foundation, conducted a rapid Health Impact Assessment (HIA) to understand how improving school nutrition standards could impact the nutritional quality of school meals, school meal participation, student dietary consumption, students' health and wellbeing, and academic performance. The HIA features several studies conducted by the Nutrition Policy Institute, including a study showing the effectiveness of removing flavored milk from schools in reducing added sugar intake without compromising the intake of milk-related nutrients. Another showed that schools successfully implemented the school meal nutrition standards per the 2010 Healthy, Hunger Free Kids Act. It also features a study showing that limiting competitive foods offered in California schools didn't lead to significant revenue loss and improved schools adherence to nutrition standards. Overall, the HIA evidence reviewed suggests that aligning school meal nutrition standards with the 2020-2025 Dietary Guidelines for Americans could have significant positive implications for child nutrition and health and is likely to increase student participation in school meal programs, improve food security, increase school food service revenue, and improve academic performance.
