The Supplemental Nutrition Program for Women, Infants and Children (WIC) provides federal grants to states for supplemental foods, health care referrals and nutrition education for low-income, pregnant and postpartum women, infants and children up to age five who are found to be at nutritional-risk. Based on recommendations from the Institute of Medicine, the foods available to participants in the WIC program underwent a significant overhaul in 2009 to better align nutrient intake among WIC participants with the latest dietary guidelines.
