Protein, Fat, and Dairy Linked to Prostate Cancer

May 21, 2014

A diet high in fiber and carbohydrates and low in fat, protein, and dairy products may prevent prostate cancer, according to research presented this week at the American Urological Association annual meeting.

Researchers analyzed the dietary habits of almost 10,000 men at risk for or suffering from prostate cancer. Results showed that a diet high in complex carbohydrates and low in protein and fat reduced cancer risk by 60 to 70 percent. Further, a fiber-rich diet reduced the risk by 70 to 80 percent. Researchers also observed an association between drinking milk and advanced prostate cancer.
In addition, dietary habits may lead to several conditions that increase the risk for prostate cancer, including obesity and high blood sugar, cholesterol, and blood pressure. Men with two of these risk factors had a 35 percent increased risk for prostate cancer; three to four risk factors increased cancer risk by 94 percent. Researchers hope to provide clearer links between lifestyle choices and cancer prevention.
