The food industry plays an important role in shaping people’s diets and, consequently, their health. Policymakers and civil society now realize that obesity poses a tremendous public health threat and that something must be done. Because of this, the industry has come under more scrutiny, which has led to a series of efforts to self-regulate. The PEACH lab’s research examines the degree to which these food industry self-regulatory pledges are effective in improving the food environment and promoting consumer health. For example, in a recently published study, we found that the restaurant industry’s Kids LiveWell program has not meaningfully altered the healthfulness of choices available on restaurant menus. We have also conducted research demonstrating links between anti-food tax movements and industry involvement and funding. The long-term goal of this work is to determine when self-regulatory efforts work and when they fall short.
