Walnut consumption slows the growth of prostate cancer in mice, and has beneficial effects on multiple genes related to the control of tumor growth and metabolism, researchers have found.
A study shows that when mice with prostate tumors consume the equivalent of an amount of walnuts that could easily be eaten by a man, tumor growth is controlled.
Prostate cancer affects one in six American men. It is one in which environmental factors, especially diet, play an important role.
Numerous clinical studies have demonstrated that eating walnuts -- rich in omega-3 polyunsaturated fats, antioxidants and other plant chemicals -- decreases the risk of cardiovascular disease.
