This report summarizes findings from the fourth School Nutrition Dietary Assessment Study, which collected data from nationally representative samples of school districts and schools in school year 2009-10. 

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 report contains nutrient and food group analyses of the USDA Foods distributed through the NSLP, CACFP, CSFP, FDPIR and TEFAP in fiscal year 2009.

This study uses the most recent data from the National Health and Nutrition Examination Survey (NHANES) to examine the diets of children who received WIC benefits. The report compares the diets of WIC-participant children to the diets of income-eligible nonparticipant children and higher income children who were not eligible for WIC benefits. 

This publication is based on the WIC Infant Feeding Practices Study (WIC-IFPS) sponsored by FNS. The WIC-IFPS is a one-year longitudinal study, which describes the infant feeding practices over the first year of life among a nationally representative sample of approximately 900 mothers who participated in WIC while they were pregnant.
