Mediterranean Diet is nowadays thought as the dietary pattern that best fulfills the need for nourishment, health and pleasure. Although most foods consumed in this diet are also present in other healthy dietary models, the Mediterranean Diet has a high content of total fat as its most distinguishing feature. Olive oil is the most representative food of the Mediterranean Diet as it is the characteristic culinary fat used.
