The study said, "The results of the trial suggest a beneficial effect of a MeDiet (Mediterranean diet) supplemented with extra virgin olive oil in the primary prevention of breast cancer."
For the study, Miguel Martinez-Gonzalez from University of Navarra in Pamplona, Spain, and coauthors followed 4,282 women, aged 60-80 years. Women at high risk of cardiovascular disease were recruited for the study.
Researchers analyzed the effects of two interventions with the Mediterranean diet - supplemented with extra virgin olive oil (EVOO) or nuts - compared with advice to women to follow a low-fat diet. During a median follow-up of nearly five years, the research team identified 35 confirmed incident (new) cases of malignant breast cancer. The findings revealed that women eating a Mediterranean diet supplemented with EVOO showed a 68% relatively lower risk of malignant breast cancer than those allocated to the control diet, women eating a Mediterranean diet supplemented with nuts showed a non-significant risk reduction compared with women in the control group.
