Walnuts help re prostate cancer.

In mice genetically engineered to develop prostate cancer, a small daily amount of whole walnut was found to reduce the size by 50% and slow the growth rate of the cancer by 30%.

Dr Paul Davis and others fed the mice whole walnuts as studies with extracts have failed to show benefits.

The daily amount used was the equivalent of 2.5 ounces in humans, about 14 shelled nuts.

People with prostate cancer have elevated levels of an inflammatory substance called endothelin. The mice fed walnuts showed lowered levels of endothelin.

High levels of another protein called growth factor 1 are thought to play a part in the start of prostate cancer. This was found to be lowered in the mice, suggesting walnuts also have a role in the prevention of prostate cancer.

The study was presented yesterday at a meeting of the American Chemical Society and has yet to be fully peer-reviewed.
