COLUMBUS, OHIO — Cancer researchers at The Ohio State University Comprehensive Cancer center are researching the abilities of berries to help fight cancer. Currently, Dr. Gary Stoner is testing the ability of black raspberry supplements to prevent or slow colon and other cancers.
Researchers already have studied the ability of freeze-dried berries to help prevent cancer in the esophagus, colon and oral cavity. Berries contain vitamins A, C, E; calcium and selenium among other components that help prevent cancer.
Adding powdered berries at 5% and 10% of an animal’s diet reduces the risk of cancer in the oral cavity, esophagus and colon by 45% to 80%. Berries may reduce the amount of genetic damage produced in tissues by chemical carcinogens, reduce the growth rate of precancerous cells and help prevent the expression of other genes associated with cancer development.
In the current human trials involving black raspberry supplements, initial results indicate that berries may affect the expression of many of the same genes in humans.
