Protein Hazards

Atkins, Paleo, and the South Beach diets all recommend a cut in carbohydrates in favor of a high-protein diet. These diets are popular because they work well in the short-term but research done by the director of the University of Southern California’s Longevity Institute, Dr. Valter Longo, shows that eating lots of animal proteins can lead to a long-term increased risk of cancer. Dr. Longo is a professor of Biogerontology at the University of Southern California. His research appeared in the journal Cell Metabolism.
