SEATTLE, May 9 /PRNewswire-USNewswire/ -- The risk of the two major prostate diseases, cancer and benign prostatic hyperplasia (BPH), can be reduced by changes in lifestyle, such as avoiding smoking, maintaining a normal weight and eating a healthy diet. Alan Kristal, Dr.P.H., associate head of the Cancer Prevention Program at Fred Hutchinson Cancer Research Center in Seattle, has conducted many studies that suggest men need not feel helpless against prostate cancer or BPH.
For example, Kristal and colleagues have found that:
-- Eating cruciferous vegetables, especially broccoli, at least three times
a week may reduce a man's risk of prostate cancer by nearly half.
Scientists believe that these vegetables protect against cancer because
they contain isothiocianates, which increase the activity of enzymes
that can both detoxify cancer-promoting compounds and decrease the
concentration of active androgens (steroid hormones) in the prostate.
-- Dietary supplementation with selenium and vitamin E may significantly
reduce the risk of prostate cancer. Kristal and colleagues found that
men who take a daily vitamin E supplement lower their risk of aggressive
prostate cancer by nearly half. Kristal and colleagues are now engaged
in a clinical trial with more than 35,000 men testing whether selenium
and/or vitamin E can prevent prostate cancer.
-- Men who eat a diet low in fat and red meat, moderate in alcohol, and
high in vegetables and lean protein have a significantly lower risk of
developing symptomatic benign prostatic hyperplasia, or BPH, a condition
associated with frequent and painful urination that affects nearly all
men by age 70. Kristal and colleague found that a high-fat diet
increased the risk of BPH by 31 percent, and that daily consumption of
