A Small Nudge for Better Health Through Reduced Salt Intake, Increased Vegetable Intake, and Smaller Portion Size

This study will investigate whether small changes (nudges) made in a cafeteria, where participants eat for 4 weeks, can improve their food behavior and health during the 4 weeks, and 6 weeks and 6 months after their stay. Half the participants will be exposed to one of four types of nudges (focused on reducing salt intake, increasing vegetable intake, reducing portion size, and a combination of these nudges), and half of the participants will eat in the cafeteria as it is currently, without modifications.
