Erin L. Richman of the University of California, San Francisco, and colleagues examined fat intake in men after a diagnosis of prostate cancer in relation to lethal prostate cancer and all-cause mortality.
The study included 4,577 men diagnosed with non-metastatic prostate cancer from 1986-2010 who were enrolled in the Health Professionals Follow-up Study.
The study, published in the journal Internal Medicine, found after a midpoint follow up of 8.4 years, there were 315 lethal prostate cancer events and 1,064 deaths. Replacing 10 percent of calories from carbohydrates with vegetable fat was associated with a 29 percent lower risk of lethal prostate cancer and a 26 percent lower risk of death from all-cause mortality.
"In this prospective analysis, vegetable fat intake after diagnosis was associated with a lower risk of lethal prostate cancer and all-cause mortality," the study authors wrote in summing up their work.
