    Hi. Wondering if John (and Mark too) would comment on your opinion of canola oil, and why it’s not the best choice of cooking or salad oils. What if it’s grown locally, would that make a difference? Many thanks.

      Hello Nancy,
      Your question is a fairly common one that I receive regularly. Canola oil has several issues that make it a poor fit for mammalian physiology. First, as a non genetically modified plant, rapeseed oil contains low amounts of erucidic acid. Although plant breeders were able to get the levels lower in what we now call canola oil, it is still there and many researchers feel that chronic consumption of erucidic acid is harmful to specific types of human cells/tissues.
      Lastt and probably the greatest fundamental problem with canola oil, whether it is Non GMO, organic, cold pressed….or not is the fact that it is very high in PUFA and they should not comprise more than 5-6% of our cellular fatty acid composition. When they exceed this percentage it really ratchets up the amount of oxidative stress and related damage to our mitochondria and other cell components.
      Lastly is the glyphosate content, but this could be avoided with a local, organic canola crop. These are extremely rare, but are out there.
      Based solely on the PUFA content, I would avoid its use as much as possible.
      I hope that this helps.
      Cheers, John

      Hi Lorraine,
      Spectrocell is an excellent lab and offers a comprehensive array of functional micronutrient testing. Genova’s “ION” urine micronutrient testing is also very good and quite comprehensive. Mark
