I’m a big olive oil snob. In the future, I’ll post about what to look for in terms of good quality extra virgin olive oils, how to store them, etc. but for now here’s a report from UC Davis that analyzed a variety of different “extra virgin olive oils” and the results are very revealing. Some highlights: 

  • Many commercially available olive oils have been contaminated with refined nut and seed oils
  • Costco olive oil is surprisingly not as bad as I would think despite the fact that it’s contaminated. At least it’s better than Whole Foods brand olive oil.
  • Stay away from Filippo Berio, Bertolli, Pompeian, Colavita, Star, Carapelli, Newmans Own Organics, Mezzetta, Safeway Select, 365, Mazola and Rachael Ray (I think everyone should stay away from her anyway!)
  • Highest polyphenol content oils tested were McEvoy Ranch and Bariani
