The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) provides federal grants to states for supplemental foods, healthcare referrals, and nutrition education. It targets low-income pregnant, breastfeeding, and non-breastfeeding postpartum women, and infants and children up to age five who are at nutritional risk. WIC helps improve the health of infants and children by providing nutritious foods and promoting healthy eating habits.
