A cross-sectional description of mobile food vendors and the foods they serve: potential partners in delivering healthier food-away-from-home choices.

Background: Food away from home (FAFH) in the US is associated with adverse health outcomes, and food dollars spent on FAFH continues to increase. FAFH studies have typically focused on restaurants and carryout establishments, but mobile food vendors - popularly known in the US as food trucks - have become more numerous and are an understudied segment of FAFH. The objective of this study was to assess mobile food vendors, their attitudes toward health and nutrition, and the foods they serve.
