Adherence to a Mediterranean diet along with avoidance of Western-type foods may contribute to a reduction in postmenopausal breast cancer risk, according to findings published in this month’s American Journal of Epidemiology.
Research was initiated in 1990 and involved 65,374 women living in France who were born between 1925 and 1950. 2,381 developed postmenopausal invasive breast cancer during a median follow-up period of 9.7 years. The findings indicate that a Mediterranean diet comprised of mostly fruits, vegetables, fish and olive/sunflower oil, was associated with a reduced risk of breast cancer only if energy intake remains within recommendations and if ‘unhealthy’ foods are not consumed in large quantities. The risk associated with the 'alcohol/Western' eating pattern was higher in the case of tumours that were estrogen receptor-positive/progesterone receptor-negative, added the researchers.
