This study explored the extent to which schoolchildren would purchase pre-cut and bagged fruits and vegetables from a mobile fruit vendor (frutero). During 14 days in fall 2008, a vendor sold fruits and vegetables at the entrance of an elementary school property in Oakland, California, at the close of each school day. Overall, 248 bags were sold at this school with a largely lower-income, Latino and African-American student population. Each successive day, an average of one additional bag of fruits and vegetables was sold by the frutero and 1.5 fewer non-nutritious items were sold by other competing vendors selling within one block of the school entrance. These findings suggest that policies encouraging the sale of nutritious foods from mobile food vendors may be beneficial for increasing access to healthy foods for schoolchildren.
