Sponsor's own description

The objective of this research was to determine if adding a plate graphic depicting the components of the Eat Lancet Planetary Health diet (Figure 1) to food labels in Stanford University dining halls would lead to dining hall patrons making dietary decisions that better resemble the Planetary Health diet in comparison to a no signage control group. The study hypothesis was that presenting students with a plate graphic featuring the healthy reference diet would decrease objective measures of the amount of meat taken and therefore the environmental impact of student meals.
