Positive Influence of the Revised Special Supplemental Nutrition Program for Women, Infants, and Children Food Packages on Access to Healthy Foods

The 2009 introduction of the revised WIC food packages has significantly improved availability and variety of healthy foods in WIC-authorized and (to a smaller degree) non-WIC convenience and grocery stores. Improved availability and variety of whole-grain products were responsible for most of the increase in the composite score of healthy food supply.


Stocking Characteristics and Perceived Increases in Sales Among Small Food Store Managers/Owners Associated with the Introduction of New Food Products Approved by the Special Supplemental Nutrition Program for Women, Infants, and Children

The WIC-approved food products were acquired in multiple ways, although acquisition generally occurred 1-2 times/week. Factors such as customer requests (87 %), refrigerator/freezer availability (65 %) and profitability (71 %) were rated as very important when making stocking decisions. Most managers/owners perceived increases in sales of new WIC-approved foods including those considered most profitable (wholegrain/whole-wheat bread (89 %), lower-fat milk (89 %), white corn/whole wheat tortillas (54 %)), but perceived no changes in sales of processed fruits and vegetables. Supply mechanisms and frequency of supply acquisition were only moderately associated with perceived sales increases.
