“The Rudd Center for Food Policy & Obesity is a non-profit research and public policy organization devoted to improving the world’s diet, preventing obesity, and reducing weight stigma. The Rudd Center serves as a leader in building broad-based consensus to change diet and activity patterns, while holding industry and government agencies responsible for safeguarding public health. Our Center serves as a leading research institution and clearinghouse for resources that add to our understanding of the complex forces affecting how we eat, how we stigmatize overweight and obese people, and how we can change.”
