A food desert is an area where residents have limited access to affordable and nutritious food. These regions often lack grocery stores, farmers' markets, and healthy food options, making it difficult for people to maintain a balanced diet. Food deserts are commonly found in low-income neighborhoods, where transportation options may also be limited. The absence of fresh produce and healthy foods in food deserts can lead to various health issues, including obesity and diabetes. Efforts to address food deserts often involve community initiatives, such as establishing community gardens or mobile markets, to improve access to healthy food options for residents.
