Black raspberries inhibit cancer
Flavonoids in black raspberries not only inhibit the growth of cancer, but they also cause cancer cells to commit suicide. Researchers at the Ohio State Comprehensive Cancer Center found that a class of flavonoids found in black raspberries called anthocyanins, slow the growth of cancer and caused cancer cells to commit suicide in rats with esophageal cancer.
"Our data provide strong evidence that anthocyanins are important for cancer prevention," said Gary D. Stoner, Ph.D., a professor in the department of internal medicine at Ohio State University.
Stoner and his colleagues fed rats an extract of black raspberries rich in anthocyanins, which they found was almost as effective as whole berry powder used in clinical trials in humans which required patients to take up to 60 grams (2.1 ounces) of powder daily. "Now that we know the anthocyanins in berries are almost as active as whole berries themselves, we hope to be able to prevent cancer in humans using a standardized mixture of anthocyanins," Stoner said.
The study results are published in the journal Cancer Prevention Research.
