Flaxseed, an edible seed that is rich in omega 3-fatty acids and fiber-related compounds known as lignans, is effective in halting prostate tumor growth, according to a study led by Duke University Medical Center researchers. The seed, which is similar to a sesame seed, may be able to interrupt the chain of events that leads cells to divide irregularly and become cancerous.
"Our previous studies in animals and in humans had shown a correlation between flaxseed supplementation and slowed tumor growth, but the participants in those studies had taken flaxseed in conjunction with a low-fat diet," said Wendy Demark-Wahnefried, Ph.D., a researcher in Duke's School of Nursing and lead investigator on the study.
