By Kathryn Doyle (Reuters Health) – Over time, eating a Mediterranean-style diet that emphasizes fish, vegetables and particularly olive oil, may lower women’s risk of breast cancer compared to following a low-fat diet, suggests a new study from Spain. In the five-year trial that randomly assigned women to different kinds of diets, those instructed to eat a Mediterranean-style diet with four tablespoons of extra virgin olive oil per day had about half as many breast cancer diagnoses as those on a low-fat diet. “With an overall healthy diet plus extra virgin olive oil there is a reduction in the hard endpoint of breast cancer,” said senior author Dr. Miguel A. Martinez-Gonzalez of the University of Navarra in Pamplona and CIBEROBN in Madrid.
