SAN FRANCISCO — Prostate tumors grew more slowly in mice fed a diet rich in walnuts, Paul Davis of the University of California, Davis reported March 22.
Previous work has shown that walnuts can benefit the heart by fighting inflammation and allowing blood vessels to dilate. Davis notes that inflammation also plays a role in many cancers, and that walnuts can tinker with production of endothelin, a protein that helps regulate prostate growth.
