“It's a diet that is proven to give you long life and it focuses a lot on olive oil, which has beneficial properties for long-term health,” adds Crandall.
Research has linked olive oil to a variety of health benefits. One study of more than 92,000 men and women, published in the Journal of the American College of Cardiology, found that those who consumed the most olive oil ─ a little more than half a tablespoon a day ─ had a 19% lower risk of death from any cause over the 28-year study period compared to those who never or rarely used olive oil. In addition, consuming more olive oil was linked to lower risk of death from heart disease, cancer and neurodegenerative disease, such as Alzheimer’s disease.
