Improving access to healthy, affordable foods can help prevent and reduce obesity among children and families. Yet many families do not have access to healthy affordable foods in their neighborhoods and communities. Food access is also an important component of food security, which is having consistent access to enough nutritious food for a healthy active life. In 2018, an estimated 1 in 9 Americans were food insecure, including more than 11 million children.

During the COVID-19 pandemic, this number rose to the highest levels ever documented in the U.S. at 38%, with nearly 1 in 2 households with children impacted. Research in this area focuses on increasing access to healthy affordable foods through grocery stores, corner stores, restaurants, mobile food vendors, farmers’ markets, and other food outlets in low-access areas including lower-income communities in urban and rural areas.
