Given the significant reach and service the Supplemental Nutrition Assistance Program (SNAP) food assistance program has for lower-income populations most vulnerable to food insecurity and poor nutrition, there is an urgent need to obtain data about the nutrition of children who participate in SNAP to determine what foods are being consumed. This analysis was designed to provide important evidence about the types and amounts of foods and nutrients consumed by children enrolled in the SNAP program, thereby helping to underscore the importance of SNAP in encouraging the purchase of healthier foods as a key component of reversing childhood obesity in this vulnerable population. Initially, the project team members reviewed the scientific literature for the effects of SNAP participation on dietary intake, types of food consumed, and obesity rates as compared to lower-income individuals who are not enrolled in the program. The team then conducted a statistical review and analysis of National Health and Nutrition Examination Survey (NHANES) data from 1998-2008 to determine the effect of the program’s current structure on the nutrition of its child and adolescent beneficiaries.

Associations of Food Stamp Participation with Dietary Quality and Obesity in Children

Studies suggest that participation in the Supplemental Nutrition Assistance Program (SNAP)—the largest federal nutrition assistance program in the U.S.—may be associated with suboptimal dietary patterns among adults, but these associations have not been extensively examined among children. This paper discusses the results of a study that examined the overall dietary quality among a national sample More

Measuring the impact of charitable food program cuts on the nutritional quality of foods

This study examines how sudden cuts to USDA programs supporting the charitable food system (i.e., The Emergency Food Assistance Program (TEFAP) and the Local Food Purchase Assistance Cooperative Agreement (LFPA)) affect the supply of healthy food available for distribution by food banks. Existing data from 15 food banks will be analyzed, and additional data will More
