The Special Supplemental Nutrition Program for Women, Infants and Children (abbreviated as WIC) is a federal assistance program of the Food and Nutrition Service (FNS) of the United States Department of Agriculture (USDA) for healthcare and nutrition of low-income pregnant women, breastfeeding women, and infants and children under the age of five. (See Child nutrition programs.) The eligibility requirement is a family income below 185% of the U.S. Poverty Income Guidelines. If a person participates in other benefit programs, or has family members who participate in the Food Stamp Program, Medicaid, or Temporary Assistance for Needy Families, they automatically meet the eligibility requirements. This program is unrelated to the USDA's Food Stamp Program. Currently, WIC serves 53% of all infants born in the US.

In 1968, a group of physicians described to the Department of Health, Education and Welfare and the USDA that young women, often pregnant, came to their clinics with various ailments that were caused by a lack of food. The doctors would prescribe needed foods, with the prescription acting as a sort of food voucher. WIC’s program beginnings surface in 1969, when the White House Conference on Food, Nutrition, and Health recommended that special attention be given to the nutritional needs of low-income pregnant women and preschool children
