In addition to the natural environment, a healthy environment can be defined by the built environment, which refers to the human-made infrastructure and resources that support human activity. One component of a built environment that impacts communities is access to affordable and healthy food. Access to healthy food can be a challenge especially in low income neighborhoods or rural areas. There are communities with limited access to stores that sell healthy food, especially high quality fruits and vegetables. The lack of access to healthy food in certain communities can be defined as a food desert and contributes to a poor diet and can lead to diet-related diseases. It is important to see where these food deserts are and find ways to improve access through grocery stores, small stores, farmers' markets, and community gardens. Although it is important to access information regarding food deserts, education on the consumption and preparation of healthy food is also an important component in the equation to take into consideration when improving overall community health.
