CHICAGO, March 25 Researchers worldwide are discovering a cornucopia of compounds in foods and dietary supplements that show promise for preventing cancer. More than a dozen research papers on this topic will be presented during a one-day symposium, Natural Products, Diets and Cancer Prevention, on Sunday, March 25, at the 233rd national meeting of the American Chemical Society.

All papers in this symposium are embargoed for 8:00 a.m. (Central Time), March 25. The symposium will be held at McCormick Place Lakeside, Room E264, Level 2.

Selected highlights are shown below:

Black raspberries show promise for preventing cancer of the esophagus, colon Using animal models (rodents) of cancer development, researchers at Ohio State University showed that animals whose diets were supplemented with black raspberries had a 60 percent reduction in tumors of the esophagus and up to an 80 percent reduction in colon tumors. Clinical trials are now underway to determine whether the berries will prevent the development of esophageal and colon cancer in humans, says study leader Gary D. Stoner, Ph.D., a researcher and professor of internal medicine at the university. (AGFD 008, Sunday, March 25, 8:45 a.m.)

Blueberries contain chemical that may help prevent colon cancer A compound found in blueberries shows promise in animal studies of preventing colon cancer, according to a joint study by scientists at Rutgers University and the U.S. Department of Agriculture. The compound, pterostilbene, is a potent antioxidant that could be developed into a pill with the potential for fewer side effects than some commercial drugs that are currently used to prevent the disease, according to study leader Bandaru Reddy, Ph.D., a professor in the Department of Chemical Biology at the university.
