Food fraud—or the act of deceiving consumers about a food or ingredient for the sake of profit—affects as much as 10% of the global food supply. Of all the instances of food fraud in the US, olive oil leads the way, making up 16% of cases (followed by milk, honey, saffron, and orange juice). Since EVOO is the most valuable oil category in the US, shady producers and dealers have plenty of incentive to mess with it in hopes of reaping more profit. Aside from imparting rotten flavors and ripping people off, this fraud deprives people of some of the health benefits that may have prompted them to buy the oil in the first place. So, what’s the best way to avoid getting fooled? Check out our best tips for finding authentic EVOO here.
