The American Cancer Society has issued a warning that so-called “food swamps” places where unhealthy food options far outnumber healthy ones are increasing across the United States. Meanwhile, the number of “food deserts” areas where residents lack access to affordable nutritious food has not improved substantially, leaving millions of people at higher risk for diet related diseases including cancer. The findings come from a new analysis of national data on food environments and their link to health outcomes.

Key Takeaways

  • Food swamps are expanding in the U.S., meaning more communities are surrounded by fast food and convenience stores instead of grocery stores.
  • Food deserts remain stubbornly common, with no significant progress in reducing them over the past decade.
  • Both food swamps and deserts are linked to worse diet quality and higher rates of obesity and chronic disease.
  • The American Cancer Society emphasizes that improving food environments could help lower cancer rates.

Understanding Food Deserts and Food Swamps

Food deserts are typically defined as low income neighborhoods where the nearest supermarket or grocery store is more than a mile away in urban areas or 10 miles away in rural areas. Without a convenient source of fresh fruits, vegetables, and whole grains, residents often rely on processed and packaged foods that are high in sugar, salt, and unhealthy fats. Food swamps, a term that has gained attention more recently, describe areas where unhealthy options dominate the landscape. In a food swamp, a person might have easy access to several fast food restaurants and corner stores selling chips and soda but no full service grocery store within walking distance. The American Cancer Society report notes that food swamps are now more common than food deserts and are growing faster.

Key Findings from the Report

The new analysis, conducted by researchers affiliated with the American Cancer Society, examined federal data on food access and retail environments across all U.S. counties. It found that the percentage of counties classified as food swamps rose between 2010 and 2020, particularly in the South and Midwest. At the same time, the share of the population living in a food desert stayed roughly the same, affecting about 10 to 12 percent of Americans. The report also highlights that both food deserts and food swamps disproportionately affect communities of color and low income households. These populations already face higher rates of diet related cancers and other chronic conditions, making the lack of healthy food access an urgent equity issue.

Implications for Health and Cancer Risk

Diet is a major modifiable risk factor for many types of cancer, including colorectal, breast, and prostate cancers. When people live in environments where cheap, calorie dense, nutrient poor foods are the easiest option, they are more likely to develop obesity and related conditions such as type 2 diabetes and heart disease. The American Cancer Society has long recommended a diet rich in fruits, vegetables, lean proteins, and whole grains as a way to lower cancer risk. The new report underscores that these recommendations are difficult to follow when healthy food is either unavailable or out of reach financially. The authors call for policy changes such as incentives for grocery stores to open in underserved areas and restrictions on the density of fast food outlets near schools and residential neighborhoods.

What Can Be Done

Addressing food swamps and deserts requires a combination of community action, policy reform, and individual awareness. On a local level, urban planners can use zoning laws to limit the concentration of fast food restaurants and to attract full service grocery stores. Community gardens and farmers markets can also improve access to fresh produce in neighborhoods without supermarkets. On a broader scale, federal and state programs such as the Supplemental Nutrition Assistance Program (SNAP) can include incentives for buying fruits and vegetables. The American Cancer Society encourages consumers to advocate for healthier food options in their own communities and to support organizations working to eliminate food inequities.

Frequently Asked Questions

What is the difference between a food desert and a food swamp?

A food desert is a neighborhood with limited access to affordable and nutritious food, usually because there is no grocery store nearby. A food swamp is a neighborhood where unhealthy food options such as fast food, convenience stores, and liquor stores greatly outnumber healthy options. Both can lead to poor diet quality, but food swamps are now more widespread in the United States.

Why is the American Cancer Society concerned about food swamps?

The American Cancer Society notes that diet plays a key role in cancer risk. Living in a food swamp makes it harder to follow a healthy diet, increasing the likelihood of obesity and other conditions that raise cancer risk. The organization advocates for changes in the food environment to support cancer prevention.

What can individuals do to improve food access in their area?

Individuals can support local efforts to bring grocery stores and farmers markets to underserved neighborhoods, volunteer at community gardens, and speak up at city council meetings about zoning laws that limit unhealthy food outlets. Voting for policies that improve food access and supporting nonprofits that address food insecurity also make a difference.
