As part of the research, the team enrolled participants who were at high cardiovascular risk on one of three diets.
This was a Mediterranean diet supplemented with extra virgin olive oil, a Mediterranean diet supplemented with mixed nuts, or a control diet.
This diet consisted of olive oil, fruits, nuts, vegetables, grains, a “moderate intake” of fish and poultry, a “low” intake of dairy, red meat, processed meat, and sweets, and wine “in moderation.” consumed with meals.
The study states: “In this trial, an energy-restricted Mediterranean diet supplemented with extra virgin olive oil or dried fruit resulted in an absolute risk reduction of approximately three major cardiovascular events per 1000 person-years, for a reduced risk relative risk of about 30 percent, among high-risk people who initially did not have cardiovascular disease.
