Extra virgin olive oil is high in monounsaturated "healthy" fats and, depending on the oil, may be rich in antioxidant polyphenols. Clinical studies show it can help lower cholesterol and control insulin levels in the body, reduce blood pressure, help with weight loss, and may reduce the risk of certain forms of cancer. In recent years, however, there have been reports that many extra virgin olive oils are "fake" or adulterated with cheaper and potentially less healthy oils.
Which are the best extra virgin olive oils? To find out, ConsumerLab.com selected and purchased ten popular extra virgin olive oils sold in the U.S. It tested them in the laboratory for purity, freshness and anti-oxidant polyphenols.
