In 2006, FNS asked the Institute of Medicine to review the WIC food packages. The IOM proposed major changes to improve nutrition and encourage breastfeeding but also expressed the concern that changes related to partial breastfeeding may have unintended consequences. The IOM recommended that FNS conduct an impact study evaluating the birth month breastfeeding changes to the WIC food packages.
This interim rule revises regulations governing the WIC food packages to align the WIC food packages with the Dietary Guidelines for Americans 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 preferences.
