Studies at Ohio State University have found significant decreases in colon tumors in rats and esophageal tumors in mice fed a diet with black raspberries. In vitro studies have shown that extracts of raspberries and blackberries may slow the growth of breast cervical, colon and esophageal cancers. Human clinical trials are underway to assess the effects of black raspberries on colon and esophageal cancers in humans.
* The king of berries in terms of health benefits.Has an extremely high overall level of phenolic compounds compared to other berries.
* Phenolic compounds such as ellagic acid, gallic acid and rutin contribute to the health benefits of black raspberries.
* Contains high levels of anthocyanins, which give them their rich, dark color. Anthocyanins work as antioxidants that help fight free radical damage in the body. The anthocyanin level of black raspberries is 214-589 mg/100g.
* Antioxidant levels of food is sometimes measured as ORAC (Oxygen Radical Absorption Capacity). The ORAC level of black raspberries is 77 µmoles /TE/g, about three times higher than blueberries, a very powerful antioxidant.
* Black raspberries are rich in ellagic acid. Ellagic acid is a phenolic compound known to be a potent anticarcinogen, anti-viral and anti-bacterial. The ellagic acid level of black raspberries is 5.37 mg/g of dry weight.
* University studies are underway to determine black raspberries' ability to slow the growth of certain cancers. In vitro studies show that extracts of raspberries and blackberries may slow or reverse the growth of breast, cervical, colon, oral and esophageal cancers.
* Studies at Ohio State University showed a 60–80 % reduction in colon tumors in rats fed a diet with black raspberries added.
* Studies at Ohio State University showed an 80% reduction in esophageal cancers in mice fed a 5-10% diet of black raspberries.
* Scientists from Ohio State University are now conducting human clinical trials into the effects of black raspberries on colon and esophageal cancer in humans.
* Black raspberries continue to generate a high level of interest from research scientists due to their potent antioxidant and anti-cancer properties.
