A traditional Mediterranean diet with added extra virgin olive oil may be tied to a lower risk of heart disease, at least in part because it helps maintain healthy blood flow and clear debris from the arteries, a Spanish study suggests. The study, published in February 2017 in the journal Circulation, examined 296 older adults at risk for cardiovascular disease who were randomly assigned to one of three diets: a Mediterranean diet supplemented with one liter per week of extra virgin olive oil, a Mediterranean diet supplemented with 1 oz. of nuts (about a fistful) per day, or a low-fat diet. The results? Only the low-fat diet was associated with reduced Low-Density Lipoprotein (LDL) and total cholesterol levels and none of the diets increased High-Density Lipoprotein (HDL) significantly.
However, the blood tests and lab work showed better HDL (the “good” cholesterol) functioning in the group assigned to the Mediterranean diet with extra virgin olive oil. The study suggests that HDL function may influence cardiovascular disease risk and thus adds to the extensive body of evidence that the Mediterranean diet may help the heart. In addition to extra virgin olive oil (which is a daily part of the 3STEPDIET Program), the Mediterranean diet includes vegetables, whole grains, fish, poultry, eggs, legumes and beans, nuts and seeds, fruit, herbs and spices, and low-fat dairy (all foods that are a part of the 3STEPDIET Program).
