Mediterranean Diet Found to Reduce Incidence and Risk of Major CV Events
Results showed the group of participants assigned to a Mediterranean diet supplemented with olive oil had 96 primary endpoint events (a composite of myocardial infarction, stroke and death from cardiovascular causes), those assigned to a Mediterranean diet supplemented by mixed nuts (walnuts, almonds and hazelnuts) had 83 events and the control group had 109 events (p = 0.015). The Mediterranean diets resulted in an absolute risk reduction of three major CV events per 1,000 person-years.
A traditional Mediterranean diet consists of high amounts of olive oil, fruit, vegetables, nuts and cereals; moderate amounts of fish and poultry; and low amounts of dairy products, sweets, red meats and processed meats. Participants assigned to the Mediterranean diet groups significantly increased weekly servings of fish and legumes, as well as olive oil and nuts, depending on the group they were in.
According to the study authors, the results of the trial might explain, in part, CV mortality rates among Mediterranean countries compared with mortality rates in northern European countries and the U.S. They note that the dietary supplements of extra-virgin olive oil and nuts were possibly responsible for most of the observed benefits of the Mediterranean diets.
