“One in 3 cancers can be prevented by eating healthy,
being active and maintaining a healthy body weight.”

~ American Institute for Cancer Research

Welcome to the Osher Center resource guide for Cancer and Nutrition, a resource for evidence-based nutrition guidelines regarding cancer prevention and survivorship. We’ve reviewed published research, as well as books and websites to provide a comprehensive overview of dietary strategies for cancer patients.

Most people believe that there is little they can do to prevent cancer. In fact, by some estimates, lifestyle factors, such as diet and exercise, play a major role in cancer prevention. Dietary habits are estimated to be a causal factor in 30% of all cancers. Combined with smoking, obesity, lack of exercise, and the over-consumption of alcohol or other drugs, 70% of all cancers can be linked to lifestyle.
