A Yale University analysis found that most people in "food deserts" in eight states would increase their access to healthy, nutritious food if they purchase groceries online and had the food delivered as part of the federal government's Supplemental Nutrition Assistance Program (SNAP).

The analysis showed that online grocery delivery systems already cover about 90% of food deserts -- places where access to healthy food is limited -- in the eight states: Alabama, Iowa, Maryland, Nebraska, New Jersey, New York, Oregon, and Washington.
