Soy Protein May Reduce Prostate Cancer Risk

ST. LOUIS, Oct. 5 - A study published in the Oct. 1 Journal of Nutrition suggests consumption of soy protein may play a role in reducing the risk of prostate cancer, Solae notes, giving consumers another healthy reason to make soy part of their diet.
The study, "Soy protein isolate increases urinary estrogens and the
ratio of 2:16 alpha-hydroxyestrone in men at high risk of prostate cancer,"
is believed to be the first study investigating the effects of soy protein
consumption on estrogen metabolism and prostate cancer in men.
"The intent of the study was to evaluate the effects of consuming soy
protein on elimination of estrogen metabolites in the urine of men at a
high risk for prostate cancer," said Dr. Mindy Kurzer, lead author of the
study and a professor in the Department of Food Science and Nutrition at
the University of Minnesota. "After taking biopsies of prostate tissue,
androgen receptors were reduced in the prostate, which is consistent with a
reduced risk of prostate cancer. In addition, significantly fewer of the
men who consumed soy protein progressed to cancer by the end of the
six-month study. We are encouraged by the results, but more studies must be
performed."
"The results of this study could be beneficial for men who are at risk
of prostate cancer," said Dr. Kathryn Greaves, Group Lead, Clinical
Nutrition at Solae. "If the results of this study are replicated in future
studies, reducing the risk of prostate cancer may be another reason to
include soy in your daily diet."
Soy has been documented to potentially improve heart health and aid in
sports performance and weight management. For more information on Solae and
