Competitive pricing for healthy foods

Evidence Rating

Scientifically Supported

Health Factors

Decision Makers

Competitive pricing assigns higher costs to non-nutritious foods relative to nutritious foods. Competitive pricing can be implemented in various settings, including schools, worksites, grocery stores or other food retail outlets, cafeterias, and vending machines. Competitive pricing can take the form of incentives, subsidies, or price discounts for healthy foods and beverages and/or disincentives or price increases for unhealthy foods and beverages. 

Expected Beneficial Outcomes (Rated)

  • Increased sales of healthy foods

Other Potential Beneficial Outcomes

  • Increased healthy food consumption

Evidence of Effectiveness

There is strong evidence that competitive pricing increases sales of low fat foods, fruits, vegetables, and water (Fox 2005a, , Kim 2006, , , AHA-Mozaffarian 2012). Price discounts or subsidies for healthier foods have also been shown to increase healthier food consumption (, AHA-Mozaffarian 2012).

Pricing affects individual behavior; adults and teenagers have been shown to purchase items that are lower in cost, whether those items are healthy or unhealthy (). Reductions in the price of low fat snacks, fruits, and vegetables increase sales of these products (Fox 2005a, , Kim 2006, , ). Effect sizes tend to be proportional; larger price differences between lower cost healthy foods and higher cost unhealthy foods are linked to greater improvements in healthy food consumption (AHA-Mozaffarian 2012).

Preliminary evidence from price discount interventions suggests that the demand for healthy foods such as fruits and low fat snacks are price elastic, which means a 1% price decrease is associated with more than a 1% increase in quantity demanded (). In some studies, positive behavior changes following subsidies that reduce the price of fruits and vegetables were sustained several months after subsidies ended. Other studies suggest that lower income populations may be more sensitive to prices than higher income populations, and youth more sensitive than adults (AHA-Mozaffarian 2012).

Lowering the price of healthy foods or raising the price of unhealthy foods has not been shown to significantly decrease revenue in school settings (, Kim 2006, ).

Impact on Disparities

No impact on disparities likely

Implementation Examples

Many schools have implemented competitive pricing in their cafeterias and vending machines, for example, North Community High School in Minneapolis, MN, Vista High School in Vista, CA, the Fayette County Public School District in Lexington, KY (Fox 2005a), Marshall County Schools in AL, and Boston Public Schools (IPHI-HCFS).

Workplace wellness policies often include competitive pricing strategies in vending machines and cafeterias. For example, in Michigan and North Dakota, worksite wellness guides encourage large and small workplaces to adopt competitive pricing for healthy foods (MI DCH-WW guide 2008, ND WW-Resources).
