food desert
n.— «Health experts have taken to calling low-income neighborhoods “food deserts,” and it is easy to see why. Supermarkets are usually in short supply and specialty produce and health-food stores are even rarer. Residents are often forced to do their food shopping in small grocery stores that carry few fresh fruits and vegetables.» —“A Streetcart Named Healthy” New York Times Mar. 1, 2008.
