Empowering people with the truth about food
Doctors, scientists, educators, and organizations coming together to build a healthier, more transparent food system.
Food should nourish us. As the science around ultra-processed food becomes clearer, more Americans are calling for transparency, accountability, and a simpler path to choosing food that supports their health. Fed UP! is building a science-first movement to share the facts behind what we’re eating, empower families, and help create a healthier food system for everyone. At a pivotal moment, new research in the American Journal of Public Health is helping pull back the curtain on how ultra-processed food impacts our health—and how Big Food companies have intentionally shaped the systems, products, and narratives behind them.
Fed UP! does not accept funding or support from ultra-processed food or beverage companies, or from organizations representing their interests. Our work is grounded in independent research focused on public health, not corporate influence.
No spin. No special interests. Just evidence-based facts.
