In response to the lack of intended program outcomes, the U.S. Department of Agriculture's Food and Nutrition Service assigned the Institute of Medicine's Committee to assess the effectiveness of the food package content. As part of the evaluation, they were to determine the special dietary needs of each subgroup of the WIC participants. This included prioritizing the targeted nutrient intake and offering recommendations for specific changes to the WIC food packages. To do this, the committee was charged with making recommendations that were "culturally suitable, non-burdensome to administration, efficient for nationwide distribution and vendor checkout, and cost-neutral." These recommendations were implemented in the form of supplemental foods that would counteract the deficiencies and excesses of the WIC food package within the bounds of cost and cultural requirements.
