A natural antioxidant abundant in blueberries called pterostilbene may help prevent colon cancer, according to an animal study reported Sunday in Chicago at the 233rd national meeting of the American Chemical Society.
"This study underscores the need to include more berries in the diet, especially blueberries," study chief Dr. Bandaru S. Reddy, chemical biologist at Rutgers University, Piscataway, New Jersey, said in a statement.
Pterostilbene is similar to the antioxidant resveratrol found in grapes and red wine, which also has anticancer activity. Pterostilbene is also present in grapes, but it is more abundant in blueberries.
Reddy and colleagues at Rutgers and the US
Department of Agriculture induced colon cancer in 18 rats and then fed the animals a balanced diet, with or without pterostilbene (40 mg/kg of diet).
At the end of the study, the nine animals that received pterostilbene supplement had 57-percent fewer pre-cancerous growths in the colon compared with the animals that were fed a balanced diet only.
