A Look Inside Food Deserts
Food Deserts Explained
Food deserts are areas that lack access to affordable fruits, vegetables, whole grains, lowfat milk, and other foods that make up the full range of a healthy diet.
Are There Food Deserts in the United States?
A review of five high income countries published in the July 2009 issue of Preventing Chronic Disease (PCD) suggests that food deserts do exist in the United States. Estimates of how much of the US population is affected can vary greatly because there is no standard definition of a food desert. According to a report by the US Department of Agriculture, a small percentage of American consumers are limited in their ability to access affordable nutritious food because they live far from a supermarket or large grocery store and do not have easy access to transportation.

How Can Food Deserts Affect Your Health?
Many scientific studies have suggested that food deserts may negatively affect health outcomes, but more research is needed to determine how access influences the types of foods consumers purchase and eat. Some researchers believe a link exists between access to affordable nutritious foods and the intake of those foods. However, other studies have shown that even after healthier food options are more widely available in food deserts, many consumers continue to make unhealthy choices based on personal preferences.
