Health Factors  
Date last updated

There are a variety of mechanisms to increase healthy options in vending machines, including reducing the price of healthy choices and increasing the number of healthy choices compared to unhealthy choices1.

What could this strategy improve?

Expected Benefits

Our evidence rating is based on the likelihood of achieving these outcomes:

  • Increased healthy food purchases

Potential Benefits

Our evidence rating is not based on these outcomes, but these benefits may also be possible:

  • Increased healthy food consumption

  • Improved nutrition

  • Improved dietary choices

What does the research say about effectiveness?

There is strong evidence that healthy vending machine options increase sales of healthy foods and access to healthy foods in university settings2 and in workplaces and schools3, 4.

A study looking at healthy vending machine options in a large health organization found a reduction in number of calories, sodium, fat, and sugar sold through vending machines when healthy options were available5. Restricting the sale of sugar sweetened beverages has been shown to reduce consumption among high school students6 and kindergartners7. Increasing healthy options in vending machines may improve dietary behaviors6, 8, 9, especially when healthy options are made relatively less expensive than unhealthy options10. Price discounts for healthier foods have been shown to increase consumption of healthier foods8, 11, 12. Nutrition standards for vending machines and increased healthy vending options are suggested to improve nutrition13, 14, 15, 16, 17, 18.

Competitive food availability through vending machines, snack bars, or à la carte, is not associated with adolescent weight gain in one study of 5th to 8th graders19, suggesting that systemic changes to the broader food environment may be needed to substantially reduce weight gain. States with strong laws governing competitive food nutrition content across grade levels, including vending machine food choices, appear to reduce adolescent body mass index (BMI) increases and the likelihood of adolescents remaining overweight20.

Vending machines generate significant revenue, particularly for schools. Some studies show no significant revenue losses from implementing vending machine policies in schools, workplaces, or hospitals21, 22, 23, 24, and possibly, a positive fiscal impact25, 26, 27. Other studies find data on revenue impacts too limited to adequately determine how changes in food options will affect school revenue28. A Los Angeles-based study indicates that effects can be neutral, positive, or negative depending on implementation29. Studies suggest that vending machines offering healthy options are feasible in hospital settings30, 31.

Successful healthy vending initiatives commonly include support from decision makers, internal and external partnerships with relevant experts, and clear communication between vendors and the community32. Contracts, a form of private regulation, may be a tool to help oversee healthy vending machine options33.

How could this strategy advance health equity? This strategy is rated inconclusive impact on disparities.

It is unclear what impact increasing healthy vending machine options may have on disparities in the food environment, especially in schools and workplaces; in access to healthy food; and in overall diet and nutrition outcomes.

Many population groups in the U.S., especially people with low incomes and people of color, live and work in areas with an unhealthy food environment and have higher rates of food insecurity than people with higher incomes and white people40. These disparities in access to nutritious foods through both food environment and financial barriers contribute to disparities in diet quality40. Disparities in diet related health outcomes also persist by income level, race and ethnicity, education background, and geographic location in the U.S.41, 42.

What is the relevant historical background?

Throughout U.S. history, discriminatory housing, lending, and exclusionary zoning policies entrenched racial residential segregation and concentrated poverty43, 44. This systemic disinvestment and exclusion by both government and private entities created and maintains community environments with limited resources, deteriorating infrastructure, hazardous industries and waste disposal sites, and many other factors that lead to poorer health outcomes for people of color and people with low incomes45, 46, 47, 48. Communities shaped by discriminatory policies are often areas that have limited access to healthy and affordable food, formerly known as food deserts49, 50. Individuals who live in these communities face higher food costs, fewer store options, and must travel further to purchase healthy food than those who live in well-resourced communities49. Residents also have increased exposure to high calorie foods that have little nutritional value, which often leads to worse health outcomes50. Many rural areas also lack access to fresh and affordable food, even in areas where farming is an important part of the local economy51.

Vending machine sales began in the early 18th century in Britain and started in the U.S. in the late 1800s. Vending machines have distributed many goods, including tobacco products, gum, candy, cigarettes, soft drinks, snacks, and even prepared foods52. Vending machines can generate revenue and increase access to the goods they sell, since vending machines are available at all hours of the day and every day of the week. In recent decades, many public health organizations have advocated for increasing healthier options made available through vending machines. In 2019, the National Automatic Merchandising Association (NAMA) announced a new public health commitment to increase healthier options by 33% in their vending machines nationwide53.

Equity Considerations
  • How many vending machines in your community offer healthy food and beverage options? What partnerships between community organizations, schools, workplaces, and public health advocates could support increasing healthier vending machine options locally?
  • Which neighborhoods in your community have higher numbers of vending machines and more unhealthy food options available than healthy food options? Where can healthy vending machine options be implemented in your community?
  • Who decides where vending machines will be placed in your community? Who decides what food items will be stocked in existing vending machines? In schools, libraries, community centers, etc.?
Implementation Examples

At the federal level, Smart Snacks in Schools was passed in 2014 and requires all foods sold at schools, including in vending machines, to meet specific nutrition standards34. In 2014, the U.S. Food and Drug Administration (FDA) also published a final rule declaring all operators owning or operating 20 or more vending machines must display calorie information for food and beverages sold from their machine35.

State initiatives supporting healthy vending machines are in Rhode Island36, Hawaii37, Alabama, Iowa, Mississippi, and Ohio38. Many localities also have healthy vending machine standards in their schools and public county buildings, for example, Chicago, IL39, Cameron County, TX; King County, WA; and several counties in California38.
