Brief Summary

The specific aims of this proposal are to 1) develop the components of a behavioral economics strategy (i.e., healthy bundle defaults) to influence diet behaviors; 2) characterize the online grocery shopping behaviors and attitudes of low-income adults nationally; and 3) examine the extent to which "healthy bundles defaults" and other behavioral economic strategies increase fruit and vegetable purchases among low-income adults in an online randomized controlled experiment.
