Most Americans consume diets that do not meet Federal dietary recommendations. A common explanation is that healthier foods are more expensive than less healthy foods. To investigate this assumption, the authors compare prices of healthy and less healthy foods using three different price metrics: the price of food energy ($/calorie), the price of edible weight ($/100 edible grams), and the price of an average portion ($/average portion). They also calculate the cost of meeting the recommendations for each food group. For all metrics except the price of food energy, the authors find that healthy foods cost less than less healthy foods (defined for this study as foods that are high in saturated fat, added sugar, and/or sodium, or that contribute little to meeting dietary recommendations).

Federal dietary guidance advises Americans to consume more vegetables and fruits because most Americans do not consume the recommended quantities or variety. Food prices, along with taste, convenience, income, and awareness of the link between diet and health, shape food choices. We used 2008 Nielsen Homescan data to estimate the average price at retail stores of a pound and an edible cup equivalent (or, for juices, a pint and an edible cup equivalent) of 153 commonly consumed fresh and processed fruits and vegetables. We found that average prices ranged from less than 20 cents per edible cup equivalent to more than $2 per edible cup equivalent. We also found that, in 2008, an adult on a 2,000- calorie diet could satisfy recommendations for vegetable and fruit consumption in the 2010 Dietary Guidelines for Americans (amounts and variety) at an average price of $2 to $2.50 per day, or approximately 50 cents per edible cup equivalent.

The increased food purchasing power offered by the Food Stamp Program can promote food security and improve the overall economic well-being of low-income households. Now, as Americans struggle with obesity and other diet-related health problems, there is interest in whether the program can be more effective in encouraging participants to make healthy food choices. ERS has compiled economic research to provide decisionmakers with information on the likely effects of various proposed strategies for improving the food choices of food stamp program participants. This overview summarizes the findings, which are presented in more detail in a series of individual briefs.

Food stamp recipients, like other Americans, struggle with nutrition problems associated with choice of foods, as well as amounts. This series of Economic Information Bulletins compiles evidence to help answer the question of whether the Food Stamp Program can do more to improve the food choices of participants. It examines the role of affordability and price of healthful foods in influencing food choices and the likely success of any policy targeted at changing food choices through food stamp bonuses or restrictions. It also examines other approaches to changing food choices, including nutrition education and potential strategies drawn from behavioral economics literature. Meaningful improvements in the diets of food stamp recipients will likely depend on a combination of many tactics. Measuring the effect of any policy change on food choices and health outcomes remains a challenge.

Currently, the effects of the Food Stamp Program on the food choices and diet quality of participants are the subject of much debate. Improved evaluation of the nutrition and health effects of the program would be of use to program and policy officials, but most of the existing research is limited by three key factors: the difficulty in separating the effect of the program itself from other factors that may be related to program participation (that is, selection bias); relative age of the data (which do not capture current programs or population behaviors); and use of outdated dietary standards and assessment methods. This brief describes current ERS activities to address these problems and improve evaluation.

The Food Stamp Program provides benefits that low-income households can use to purchase food in grocery stores. The rise in obesity has raised the question of whether food stamp participants would purchase more healthy foods, such as fruits and vegetables, if food stamp benefits were higher. This report examines household food spending patterns and how they differ across income levels to provide insight into how participants might change their food spending in response to additional income.
