A study published in BJU International found that adhering to healthy diets seems to don’t have any effect on prostate cancer risk, but following an unhealthy weight-reduction plan might increase the chance of developing aggressive prostate cancer.
The study assessed the diets of 15,296 men recruited in Spain in from 1992–1996. Amongst these men, 609 prostate cancer cases were identified during a median follow-up of 17 years. Diets were categorized as Western, Prudent, or Mediterranean. The Western dietary pattern consisted of a high intake of high-fat dairy products, processed meat, refined grains, sweets, caloric drinks, convenience food, and sauces, and a low intake of low-fat dairy products and whole grains. The Prudent dietary pattern was characterised by a high intake of low-fat dairy products, vegetables, fruits, whole grains, and juices. The Mediterranean dietary pattern represented a high intake of fish, vegetables, legumes, boiled potatoes, fruits, olives, and vegetable oil, and a low intake of juices.
No effect over prostate cancer risk was detected for the Prudent and Mediterranean dietary patterns, but detrimental effect was observed with the Western dietary pattern. This effect was only observed for aggressive tumors.
Our results indicate that avoiding unhealthy dietary habits might be one of the best dietary strategy to stop aggressive prostate cancer.”

“Substituting the intake of Western-type weight-reduction plan products by products characteristic of the Mediterranean weight-reduction plan could also decrease the chance of other chronic diseases,” added co–senior creator Marina Pollán, PhD, of the Carlos III Institute of Health and CIBERESP, in Spain.
“The knowledge provided by the Spanish cohort of the European Prospective Investigation into Cancer and Nutrition-;or EPIC-;has contributed to improving scientific knowledge of the connection between weight-reduction plan and cancer and other chronic diseases,” added co–senior creator Maria-José Sánchez, MD, PhD, lecturer on the Andalusian School of Public Health, scientific director at ibs.GRANADA and researcher at CIBERESP, in Spain.
