RT Journal A1 Dennison BA T1 Public policy to improve child nutrition and health: Challenges and opportunities JF Archives of Pediatrics & Adolescent Medicine JO Archives of Pediatrics & Adolescent Medicine YR 2012 FD May 1 VO 166 IS 5 SP 485 OP 487 DO 10.1001/archpediatrics.2012.196 UL http://dx.doi.org/10.1001/archpediatrics.2012.196 AB You are what you eat. An old adage that recognizes the critical role that diet has on health. With the goal of improving the nutrition and health of targeted populations, federal, state, and local governments have developed and implemented public health policies and programs to prevent nutritional deficiencies by providing nutritious foods, fortifying foods or beverages, and, more recently, limiting the calorie, fat, or sugar content of high-calorie, low-nutrient foods. Two articles1- 2 in this issue of the Archives contribute to the growing evidence base that public health nutrition policies can favorably impact children's diets and their health.
