Interim rule. Vol. 72, No. 234. This interim rule revises regulations governing the WIC food packages to align the WIC food packages with the Dietary Guidelines for Americans (DGA) 1 and current infant feeding practice guidelines of the American Academy of Pediatrics, better promote and support the establishment of successful long-term breastfeeding, provide WIC participants with a wider variety of food, and provide WIC State agencies with greater flexibility in prescribing food packages to accommodate participants with cultural food references.
