Blueberries have been lauded for their antioxidant ability and cancer-fighting effects. But another berry may offer protection against some of the deadliest forms of cancer.

Researchers at the University of Pittsburgh evaluated the effect of a compound extracted from blackberries called cyanidin-3-rutinoside (C-3-R) on cultured human leukemia cells. The C-3-R was tested on several cell lines of human leukemia, and the test was repeated using cell cultures of lymphoma, another immune-based cancer. The scientists found that when applied at low doses, C-3-R killed half the cancer cells within 18 hours of treatment. When applied at higher doses, the blackberry extract killed all cancer cells present within 18 hours.

According to cancer expert and researcher Gary Stoner, 1.5 to 2 cups of fresh berries may be the ideal dose for staving off certain types of cancer. So whether you choose marionberries (the “Cabernet of blackberries”), traditional evergreen blackberries, or big and bold boysenberries, you’ll get a burst of summer-fresh flavor… and a bushel of cancer protection to boot.

Kelley Herring is the Founder & CEO of Healing Gourmet – a multimedia company that educates on how foods promote health and protect against disease. As a young adult, Kelley battled a debilitating health condition that went misdiagnosed by multiple doctors for more than a year. Finding no help from “modern medicine”, she turned to her own knowledge of biochemistry and her passion for health research. She soon learned that her symptoms were related to nutrition and within weeks, she charted a course back to health with nothing more than simple lifestyle changes and the power of the plate. The lessons she learned spawned the creation of Healing Gourmet. Kelley is a firm believer in vigorous exercise, moderate sun exposure and delicious, healthy, home-cooked meals.
