Black Raspberries Shown to be Highly Effective in Preventing Cancer

A new study conducted by Ohio State University researchers has documented the power of black
raspberries to prevent the development of tumors in the esophagus and colon. The study's findings
were presented at the March 2007 national meeting of the American Chemical Society.
Gary Stoner, Ph.D., a professor of internal medicine at Ohio State University, led the study. Stoner and
his co-workers prepared a powdered, freeze-dried extract from black raspberries then gauged its effect
on rats that had been exposed to a cancer-causing substance. The research team measured the
prevalence of malignant tumors. Compared to a control group, the rats fed black raspberry extract
showed a 60 percent reduction in tumors of the esophagus and up to an 80 percent reduction in colon
tumors.
"That's a much higher reduction than I thought we'd see," Stoner said, "This suggests that berries bind
up a good portion of free radicals, preventing them from causing damage in the body."
Black raspberries are rich in vitamins A, C, E, and folic acid and contain the minerals selenium, zinc, and
calcium. In addition, black raspberries have a higher content of anthocyanins than most other berry
types, as well as phenols, such as ellagic, coumaric and ferulic acid. All of these substances are
recognized as "chemopreventive agents," Stoner said.
"We do know from epidemiologic studies that vegetable and fruit consumption is protective against
cancer and, from our work, we would suggest that berries be one of those helpings, at least two or three
times a week," said Stoner.
Clinical trials are underway to examine the potential of black raspberries to prevent esophageal and
colon cancer in humans. Stoner and his team have begun analyzing the effects of the fruit in people
with Barrett's esophagus (a condition of the esophagus that increases risk of esophageal cancer) and
precancerous colon polyps. Preliminary results show the berries are well tolerated at doses similar to
those used in animals.
