Policy, Environment & Prevention

Population-level prevention has gained renewed urgency as ultra-processed foods now supply over half of US caloric intake. The track will review evidence on sugar-sweetened beverage taxes (Mexico, Philadelphia, UK soft drinks levy), front-of-package warning labels, ultra-processed food classification (NOVA) and the recent NIH metabolic ward studies, restrictions on child-directed marketing, and built-environment interventions including walkability and food-desert remediation. Sessions will also address the FDA Healthy claim, USDA dietary guidelines, school-food standards, and the political economy of obesity prevention in low- and middle-income countries.
