Walnuts for prostate cancer

Scientists at the University of California-Davis have shown for the first time that walnuts reduce the size and growth rate of prostate cancer in animals. The results of their study have been made public during the national meeting of the American Chemical Society being held this week in San Francisco (USA).

Walnuts are a rich source of healthful substances, including omega-3 fatty acids, which are also more expensive foods like salmon, gamma tocopherol, a form of vitamin E, polyphenols and antioxidants.

Explains Paul Davis, director of research, “the nuts should be part of a healthy diet for the prostate, a balanced diet with plenty of fruits and vegetables.” In fact, studies show that tomatoes and grapefruit juice also reduce the risk of prostate cancer.

Scientists have recently shown that nuts can combat heart disease by reducing levels of endothelin, a substance that increases the inflammation of blood vessels. This effect is added to the reduction in blood levels of bad cholesterol, cholesterol of low density lipoproteins or LDL. Since people with prostate cancer have elevated levels of endothelin, the scientists decided to test whether nut consumption may be beneficial in prostate cancer.

Davis and his team fed laboratory mice genetically programmed to develop prostate cancer, with the equivalent of 14 walnuts daily for two months. A control mice group followed the same diet with soybean oil. Fed mice developed nuts prostate cancers that were 50 percent smaller than the control mice. These cancers also grew 30 percent slower.

As if this were not enough, genetic analysis showed that walnuts also had large beneficial effects on genes involved in the control of tumor growth. Right.
