Most shoppers know that extra virgin olive oil is the highest grade of olive oil available--all natural, full of flavor and healthy compounds. But what other forms of olive oil are there and should you buy them?
The first thing to know is this: if an olive oil is not described as "virgin" then it likely contains oil that has been refined. This is in fact the case with all cooking oils on the supermarket shelf (e.g. vegetable, corn, canola, etc.).
Why are some olive oils refined? All olive oil—i.e., all grades, from regular and light tasting olive oils to extra virgin—are harvested once a year and the oil extracted mechanically, without the use of chemicals. The resulting oil is graded. The best tasting olive oil meeting strict quality and purity parameters can be sold as extra virgin olive oil. Extra virgin olive oils undergo only very minimal processing, such as filtration. Oils that don't meet the high standards of extra virgin can be refined—a purification process that removes flavor and color, identical to the process that other neutral tasting oils go through like corn, canola and soybean oils. Typically refined olive oil is blended with about 15-20% virgin or extra virgin olive oil to give it some taste and color before it is sold. So, if a product is called simply "olive oil" (or “regular olive oil” or “classic olive oil” or sometimes even “pure olive oil”) it is a mixture of two types of olive oil: refined and virgin and thus it will have a little olive flavor from the added virgin olive oil. If a product is called “light-tasting” olive oil, less virgin olive oil is added, and therefore the oil will be neutral tasting.
"Olive oil" is 100% authentic olive oil that has many of the same health benefits as extra-virgin olive oil at a lower cost. Here are some facts about olive oil.
Some people refer to "olive oil" as classic olive oil, regular olive oil or pure olive oil, although this last term is discouraged to avoid confusion. Olive oil is beloved by those who prefer a lighter tasting olive oil but still with the healthy monounsaturated fat profile.
Light-tasting or extra light-tasting olive oil is similar "Olive Oil" but contains a higher percentage of refined olive oil. It has the same number of calories and grams of fat as all olive oils; because it has less virgin olive oil enrichment, it has less polyphenols and antioxidants that "olive oil." The word "light" means it has a lighter flavor.
It really comes down to a question of taste preferences and budget.
And keep in mind the general rule that all olive oils are healthy, but the more flavor, the more health benefits you can expect. To find an olive oil that has been certified for quality and authenticity, check out our list of certified olive oils.
