In the category of diet buzz backed by legit science, one of the few approaches that makes the cut is the Mediterranean diet. And research from The Journal of Urology lends more credence to a regimen heavy in olive oil, seafood, fresh produce, and nuts.
Of 2,000 men, those who stuck most closely to the Mediterranean diet had a 30 percent lower risk of aggressive prostate cancer, the second-leading cause of cancer death among American men. According to study author Adela Castelló, it’s likely the diet’s combination of diverse, nutrient-rich foods is what makes it so effective against the disease.
Fish, in particular, is linked with a lower incidence of deaths from prostate cancer; extra-virgin olive oil may help kill malignant cells; and lycopene—an antioxidant in tomatoes—may lower chances of prostate cancer recurrence.
