Competitive pricing for healthy foods

Evidence Rating  
Scientifically Supported
Evidence rating: Scientifically Supported

Strategies with this rating are most likely to make a difference. These strategies have been tested in many robust studies with consistently positive results.

Health Factors  
Decision Makers

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

Expected Beneficial Outcomes (Rated)

  • Increased sales of healthy foods

Other Potential Beneficial Outcomes

  • Increased healthy food consumption

  • Reduced energy use

Evidence of Effectiveness

There is strong evidence that competitive pricing increases sales of healthy foods, including low-fat foods, fruits, vegetables, and water1, 2, 3, 4, 5, 6. Price discounts or subsidies for healthier foods can also increase healthier food consumption1, 5, 6.

Pricing affects individual behavior; adults and teenagers have been shown to purchase items that are lower in cost, whether those items are healthy or unhealthy7. Reductions in the price of low-fat snacks, fruits, and vegetables increase sales of these products1, 3, 4, 5, 8, 9. The size of the price difference matters; larger price differences between lower cost healthy foods and higher cost unhealthy foods are linked to greater improvements in healthy food consumption6. Overall, pricing incentives improve dietary choices and change consumer behavior when implemented alone or in combination with other interventions such as nutrition education1.

Preliminary evidence from price discount interventions suggests that there is a strong demand for healthy foods such as fruits and low-fat snacks, such that a 1% price decrease is associated with more than a 1% increase in quantity demanded5. In some studies, positive behavior changes following subsidies that reduce the price of fruits and vegetables have been sustained several months after subsidies end. Other studies suggest that populations with lower incomes may be more sensitive to prices than those with higher incomes, and youth more sensitive than adults6.

Competitive pricing of healthier foods and beverages along with healthy food marketing strategies has been shown to improve weight status for children and adolescents, especially as part of a broader multi-component school-based intervention to improve the food environment10.

Competitive pricing that increases the purchase and consumption of fresh fruits and vegetables, especially those grown locally and in season, instead of unhealthy, highly processed items may reduce fossil fuel energy used to produce, process, and transport food11, 12, 13. Competitive pricing initiatives may also reduce the energy intensity of an individual’s diet if more plant-based foods are consumed in place of animal products11, 14.

Lowering the price of healthy foods or raising the price of unhealthy foods has not been shown to significantly decrease revenue in school settings4, 9, 15, and in some cases, has increased revenue and total profits1.

No impact on disparities likely

Implementation Examples

Many schools have implemented competitive pricing in their cafeterias and vending machines, including North Community High School in Minneapolis, MN; Vista High School in Vista, CA; the Fayette County Public School District in Lexington, KY8; Marshall County Schools in AL; and Boston Public Schools16.

Workplace wellness policies often include competitive pricing strategies in vending machines and cafeterias. For example, in Michigan, worksite wellness guides encourage large and small workplaces to adopt competitive pricing for healthy foods17

There are also many grocery stores, convenience stores, and other food retail outlets using competitive pricing to market healthy food options and promote fruit and vegetable sales as part of a healthy food retail model, for example, the Healthy Neighborhood Store Project in Omaha, Nebraska and Northgate Market in Inglewood, California18.
