Which is best: extra virgin, virgin, or plain olive oil?
The difference between the olive oils you listed is their acidity level, which affects mostly taste, not nutritional content. Lower acidity oils, such as extra virgin, tend to have more anti-oxidants, but that is not reflected in their classification. Anti-oxidants in olive oil may help prevent heart disease and cancer so sticking with extra virgin seems to make sense. Pomace olive oil is processed with hexane and other solvents just as most seed oils like canola, corn, safflower, soy, etc. This removes many of the minor constituents which may be the healthiest part of this natural product.
