We all know that grapes are good for you, they’re a great source of vitamins K and C, and new research has revealed that grape seed extract may be beneficial for colorectal cancer sufferers.

grape seedScientists from the University of Colorado believe that they have evidence to suggest that grape seed extract (GSE) may inhibit the growth of colorectal cancer cells. Their study results showed that grape seed extract is able to selectively attack cancer cells, leaving the healthy cells untouched. Molly Derry, lead researcher at the CU Cancer Centre in Colorado explained, “We’ve known for quite a while that the bioactive compounds in grape seed extract selectively target many types of cancer cells. This study shows that many of the same mutations that allow colorectal cancer cells to metastasize and survive traditional therapies make them especially sensitive to treatment with GSE.”

Remarkably, the grape seed extract appeared to become more effective with the more aggressive the type of cancer, and required less grape seed extract. Derry explained, “It required less than half the concentration of GSE to suppress cell growth and kill 50% of stage IV cells than it did to achieve similar results in the stage II cells.”

Grape seed extract has been the focus of many scientific studies, including research into possible benefits for cardiovascular conditions, leukaemia (read about that here) and Alzheimer’s disease too.
