Resource | Research and Data | Promoting Healthy Eating Food Expenditures and Diet Quality Among Low-Income Household and Individuals

The purpose of this study is to identify whether spending more money on food leads SNAP and other low-income households to purchase and consume more nutritious foods. Specifically, the study analyzed the percentage and absolute change in diet-quality measures that are associated with a 10-percent increase in food expenditures for SNAP participants and income-eligible nonparticipants. The study also seeks to identify other factors or household characteristics that may affect this relationship.

Resource | Research and Data | Promoting Healthy Eating Implications of Restricting the Use of Food Stamp Benefits

Because of concerns about poor diet, overweight, and obesity among low-income Americans, there is considerable interest in using federal nutrition assistance programs to promote healthy choices. Some argue that food stamp recipients should be prohibited from using their benefits to buy foods with limited nutritional value (commonly described as “junk” foods). The Food Stamp Act currently places few limits on the use of food stamp benefits, as long as they are used to buy food to eat at home. The idea of restricting the use of food stamp benefits may be appealing on its face. However, upon closer examination, serious concerns emerge regarding the feasibility and rationale for the proposed restriction.

Resource | Research and Data | Food Security Impact of Food Stamp Payment Errors on Household Purchasing Power

Most discussion of payment accuracy in the Food Stamp Program focuses on the overall level and cost of payment errors. Rarely does the discussion focus on the impact of payment errors on individual households affected. This analysis – based on 2003 food stamp quality control data – leads to two broad conclusions. First, virtually all households receiving food stamps are eligible. Thus, the problem of erroneous payments is not so much one of determining eligibility, but rather one of attempting to finely target benefits to the complicated and changing circumstances of low-income households. Second, most overpayments to eligible households are small relative to household income and official poverty standards. As a result, most food stamp households are poor, and they remain poor even when overpaid.
