The researchers recognized fast-food eating places on the route between youngsters’s homes and their faculties. Quick meals eating places included the key hamburger chains and drive-in eating places (e.g. McDonald’s, Burger King, Wendy’s), dairy shops with massive fast-food menus (e.g., Dairy Queen), take-out pizza institutions, quick-service taco locations (e.g., Taco Bell).
