Food deserts are geographical areas where residents have limited access to affordable, nutritious foods such as fresh fruits, vegetables, whole grains, dairy products, meat, and fish. These communities, often concentrated in low-income and historically marginalized neighborhoods in the United States, suffer from a lack of grocery stores, farmers’ markets, and other sources of healthy food. As a result, residents in food deserts face health disparities and are more susceptible to chronic diseases such as obesity, diabetes, heart disease, and high blood pressure.
The causes of food deserts are complex and multifaceted, with systemic issues like racism and poverty playing a significant role. Social, economic, and political factors contribute to reducing people’s access to healthy foods. Food insecurity, racial residential segregation, poor access to transportation, and limited opportunities for education and employment are among the contributing factors affecting these communities.
One emerging term used to address the root causes of poor access to healthy foods in communities of color and low-income white populations is “food apartheid.” Food apartheid highlights the systemic racism and health inequities within the corporate-controlled food system. This term challenges the notion of “food desert,” which fails to capture the deeper issues faced by these communities and inadequately represents their identity.
Food insecurity, defined as the lack of physical and economic access to sufficient nutritious foods, is a significant concern in food deserts. Studies show that food insecurity is 2.5 times greater among low-income communities living in food deserts compared to the national average. Social determinants of health, such as education, employment, socioeconomic status, access to healthcare, and racial segregation, further exacerbate the problem of food deserts.
Racial segregation plays a crucial role in shaping food deserts, as low-income communities with higher proportions of Black and Latino populations are disproportionately affected by poor food access. Evidence shows that racial segregation places historically marginalized populations, particularly Black individuals, in impoverished neighborhoods, leading to higher rates of food insecurity among these communities.
Another critical factor contributing to food deserts is poor access to supermarkets and local food markets, particularly in predominantly Black and Hispanic neighborhoods. Transportation and proximity to supermarkets also influence food access, with households in food deserts having less access to affordable and healthy foods compared to wealthier areas.
Statistics on food deserts in the United States are based on food insecurity, income status, and access to stores and vehicles. An estimated 71.4 million American households were food insecure in 2014, with 31.6% of low-income households experiencing food insecurity in 2016. The Food Environment Atlas, developed by the U.S. Department of Agriculture, provides an interactive map showing information on food insecurity, socioeconomic conditions, and proximity to supermarkets in different regions of the country.
Health effects of food deserts are far-reaching, with diet and nutrition playing a significant role in chronic diseases such as heart disease, diabetes, and cancer. Low-income, historically marginalized communities experiencing food insecurity have higher rates of obesity and chronic ailments related to poor nutrition.
Addressing food deserts requires comprehensive and multi-faceted solutions. While increasing the number of grocery stores is one step, it is not sufficient to achieve equitable food access. Government policies must address structural issues like racism and classism, with small shifts in policy potentially alleviating food insecurity. Community-based solutions, such as community gardens, farmers’ markets, surplus food sharing programs, federal food assistance programs, and food pantries, play a crucial role in improving food access in food deserts.
Individuals living in food deserts can improve their nutrition on a budget by buying canned or frozen goods, trying non-meat protein sources, shopping for in-season produce, and freezing leftovers. The USDA’s National Hunger Hotline and various food assistance programs provide immediate support for those experiencing hunger.
Efforts to combat food deserts enjoy broad support, as they not only promote better health outcomes but also contribute to economic development and job creation in underserved neighborhoods. By addressing the root causes of food deserts and implementing comprehensive structural and policy changes, equitable food access can be achieved, ensuring the well-being and health of all communities.
