For men who are concerned about their prostate health, one consistent recommendation over the years has been to add to their diets healthy fats, like the omega-3 fats found in fatty fish, and to cut back on unhealthy fats, like trans and saturated fats. A report in the American Journal of Epidemiology muddies the waters on this.
A study of men taking part in the nationwide Prostate Cancer Prevention Trial found a link between high intake of heart-healthy omega-3 fats and increased risk of developing aggressive, high-grade prostate cancer, while high intake of artery-damaging trans fats was linked to a lower risk.
Should these results prompt men to scale back on fish and eat more processed food? No. Experts I talked with recommend staying the course when it comes to dietary fats. Read my full report on the Harvard Prostate Knowledge blog.
