Women who eat a Mediterranean diet with a little extra virgin olive oil have a lower risk of breast cancer, researchers reported in yet another study showing the health benefits of the approach.
Women who participated in the study who added extra-virgin olive oil to their diet had a 62 percent lower risk of breast cancer over the next five years or so, according to researchers at the University of Navarra in Pamplona.
The study was done in Spain, where people presumably eat the Mediterranean diet. The diet is characterized by lots of salad, fruit, vegetables, nuts, a little fish, a little lean meat, a small amount of cheese — and olive oil, of course. Wine is also served at meals.
The volunteers in the trial, however, were given extra counseling, and a weekly supply of either extra-virgin olive oil or mixed nuts.

The 4,282 women in the trial were, on average, about 68 and obese, with an average body mass index of 30.4 — just over the line for clinical obesity.
