One major problem with the extra virgin olive oil, offered in stores US-wide, is this one: It isn’t always what you think it is! The real virgin olive oil is extracted using natural methods and standardized for purity and sensory qualities like taste and smell.
Some lower quality oils can be extracted from olives using chemicals-solvents and heat. These are the so-called refined or “light” olive oils. But the worst thing of all is that producers dilute (that is adulterate) virgin olive oil with other, cheaper types of edible oils (like soybean and canola oils) to make extra profits!
