There’s more good news about berries, dark-colored berries especially. Berries contain antioxidants and vitamins that have been shown to inhibit the development of cancer of the esophagus, colon and oral cavity in animals. Now researchers want to see if they have the same effect in humans.

Berries contain phenolic compounds with high-antioxidant potential. Phenols called anthocyanins give berries their color. Dark berries, such as black raspberries and blackberries have a higher content of these anthocyanins.

Scientists at Ohio State University are conducting the research. This food-based approach to cancer prevention has many advantages, including the absence of toxicity of berries to humans.

Participants in the study are patients with early stage colon cancer will consume the equivalent of 2½ cups of black raspberries per day for 2 to 4 weeks. The patients have all undergone colonscopy prior to the study and tissue samples of their tumors taken. Following the study, physicians will again remove tumor tissue for study to see if the berry treatment had any effect on cell growth and tumor development.

OSU Studies Berries in Colon Cancer Prevention

The Agricultural Research Service, a branch of the US Department of Agriculture, has reported findings from a study that seem to indicate that eating berries may protect the brain from age-related deficits through antioxidants.

Laboratory animals were fed berry extracts and then treated to accelerate the aging process. The researchers report that the animals fed the berry extracts were protected from damage to brain function.

The new findings add to a lineup of research studies published during the past eight years showing reduced, or in some cases reversed, declines in brain function among rats whose diets were supplemented with either blueberry, cranberry or strawberry extracts or Concord grape juice.
