MUFAs in the Media: Olive Oil
Tuesday, June 15th, 2010

Are you under the impression that extra light olive oil is lower in fat and calories than its regular counterpart?  If so, you are not alone.

The good news, however, is that you’ll benefit from the latest USDA olive oil labeling enforcement set to take place in October of this year.    

Conveniently timed at the peak of harvesting season for the olive tree, the USDA will be working alongside the Olive Oil Council to design science-based standards for olive oil based on fatty acid composition, odor, color, flavor, and UV absorption.


The newest guidelines are in response to mass confusion amongst consumers about the quality, taste and production of different oils.  Without the proper labeling classification, major olive oil distributors were engaging in misleading marketing strategies— like the extra light example above, or slapping extra-virgin (to indicate highest quality/taste) on their labels.  These practices further blurred the lines between high-quality and mediocre oils. 

Let’s clear a few things up here.

A Little Bit About Olive Oil:

Olive oil is produced from a wide variety of olives designated based on their diversity, climate and location.  Fun fact: Did you know that only GREEN olives are strictly used to make oil?  One tablespoon of olive oil contains 126 calories, and 14 grams of fat.  Of these 14 grams of fat, an impressive 11 grams are monounsaturated fatty acids (MUFAs).  That’s almost half of your daily recommended value!
