Note(s): Numbers in parentheses are standard errors. *, **, and *** indicate statistical significance of an alpha level of α < 0.01, α < 0.05, and α < 0.1. Models 2 estimated with a base of 18–24 year old males with less than a high school education. Foodie models estimated with 448 degrees of freedom and non-foodie models estimated with 568 degrees of freedom
