My Healthy Today: Menopause Study: Flaxseed doesn't reduce women's hot flashes

Dr. Mark Kris, a cancer specialist at Memorial Sloan-Kettering Cancer Center in New York, said the flaxseed results are disappointing
"There were so many testimonials that we thought flaxseed was going to work, but a testimonial is not a rigorous clinical trial result, and that's what our patients deserve," he said.
"Even natural products do have side effects," so it's important to test them in studies such as this one, he said.

Decreased severity of ovarian cancer and increased survival in hens fed a flaxseed-enriched diet for 1 year

ConclusionsThese findings show that 10% flaxseed supplementation for 1 year in the laying hen results in a significant reduction in the severity of ovarian cancer, but no change in the incidence of the disease. Hens fed flaxseed had overall better health and reduced mortality. These findings may provide the basis for a clinical trial that evaluates the efficacy of flaxseed as a chemosuppressant of ovarian cancer in women.

OBJECTIVE: "With the exception of the laying hen, no other animal model of spontaneous ovarian surface epithelial cancer replicates the human disease."
