Abstract

Given that most Americans do not consume enough whole grains to satisfy Federal dietary recommendations, in 2009, the U.S. Dept. of Agriculture (USDA) altered its Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) by adding 100-percent whole-wheat bread (and other whole-grain options like brown rice) to food packages for children and pregnant or breastfeeding women. Published research suggests that participant diet quality has likely improved, but study results are mixed. Other research has explored the availability and cost of whole-grain products in the WIC-allowed, 1-pound (16-ounce) package size at retail stores. In 2014, USDA asked the National Academies of Sciences, Engineering, and Medicine (NASEM) to convene a committee of experts to conduct an independent, comprehensive scientific review of WIC food packages and recommend cost-neutral changes in line with the nutritional status and food and nutrition needs of the WIC-eligible population. In 2017, that committee recommended a number of changes to participants’ food assistance benefits. These include offering bread and other whole-grain products in more standard package sizes. Concurrent to NASEM’s review of the WIC food package, the Agricultural Act of 2014 required the Dietary Guidelines for Americans to expand to include infants and toddlers from birth to 2 years, as well as women who are pregnant, beginning with the 2020 edition. USDA will consider changes to the WIC food packages once this work is complete. In this study, we use a combination of store- and household-level purchase data to revisit some key questions about WIC participants’ whole-grain benefits. We focus on bread in a case study of the products that may be purchased with these benefits.<br />Store-level purchase data from Information Resources, Inc. (IRI) were used to examine the price and sales volume of 100 percent whole-wheat bread, and household-level data from the National Household Food Acquisition and Purchase Survey (FoodAPS) were used to examine the propensity of WIC households to purchase whole-grain breads. In this report, the term “100 percent whole wheat” is used when referring specifically to bread of this type, and the term “whole grain” is used elsewhere in the report. A variety of statistical techniques were used in the analysis, including summary statistics and T-tests for differences between group means. To capture the full association between WIC participation and whole-grain purchases among households, ERS would need to include separate analyses for all relevant whole-grain product types, which is beyond the scope of our study and data.
