ABSTRACT

Prostate cancer is the most diagnosed neoplasm in American males. Epidemiological data suggest that increased dietary fiber may lead to a reduced risk of breast cancer. Several lines of evidence exist to strengthen the correlation between dietary fiber and the reduction of serum testosterone. Studies looking specifically at the influence of dietary fiber on prostate cancer and/or serum androgen levels are few. Increasing the amount of dietary fiber consumed by the male population, while a tremendous undertaking, may prove more beneficial in the long term than additional screening modalities. Dietary fiber may result in the alteration of the enterohepatic cycling of estrogens. By increasing the intake of dietary fiber, the incidence of breast cancer may be reduced. It is evident, therefore, that dietary fiber can effect the development of one hormone-dependent cancer by reducing the circulating levels of sex hormones.
