A wealth of studies has pointed to the heart benefits of diets rich in fish. A Swedish study now finds another reason for male diners to request finned fare: prostate protection.
Researchers have inhibited prostate cancer in animals by feeding them the omega-3 fatty acids that characterize fish oil. Paul Terry and his colleagues at the Karolinska Institute in Stockholm wanted to find out if the same held true in men, so they focused on 3,100 pairs of male twins born between 1886 and 1925.
Thirty-four years ago, each of the men had filled out a detailed dietary questionnaire. As of 4 years ago, 466 of the participants had been diagnosed with prostate cancer. Roughly three-quarters of these men died of the disease.
