Myth 2: “Pure” olive oil is best: But that term "pure" actually means a blend of refined and virgin oils, falling lower on the grade scale than extra virgin. (And while we’re clarifying terms, let’s define "refining": It’s the process by which inferior olive oil is made edible).
Myth 3: "Light" olive oil has fewer calories: Light isn’t the diet-friendly oil choice. It just refers to refined oil that has a lighter flavor—not caloric load. Choose extra-virgin to get the most antioxidants.
