The olive tree originated in Asia Minor around 6000 years ago and then spread to all the Mediterranean basin. Olive oil is extracted from the pulp of its fruits [1–3]. Many studies show that the nutritional pattern of the so-called Mediterranean Diet is associated with a lower incidence of age-related diseases related to inflammation and oxidative stress, such as cardiovascular disease, Parkinson's disease, Alzheimer's disease and cancer [4–7]. It is now clear that olive oil, as a main source of fat, must play a key role in explaining the health benefits of the Mediterranean Diet
