RE: Canola Oil As A Replacement For Olive Oil In Cooking: A Foray Into Alzheimer's
Olive oil is terrific stuff. I've used canola oil also because of its Omega 3/6 ratio. It is a cheap source of omega-3 and holds up well at a high temperature. It's hard to know if canola oil is an issue or simply over-reliance on it as a single source of fat. Also, I only use organic canola oil, since the conventional stuff comes with a side order of RoundUp, and that may cause issues also (as has been speculated with the wheat "allergy"; less than 10% of the population seems to have any actual gluten issues, but the herbicides on the wheat may be a bigger story). As always, it seems best to use everything in moderation and include variety.
Indeed, for flavor alone, it is IMO the best cooking oil.
This research article wasn't really reporting any inherent issue with canola. The methodology they used was designed to probe whether or not it had similar beneficial properties, as had been previously reported for olive oil (SEE HERE: http ://pubs.acs.org/doi/abs/10.1021/cn400024q). What is described is more a rejection of the hypothesis that with regards to amyloid beta plaques and alzheimer's indicators that canola has the same protective effects that olive oil reportedly does.
We can not, from this research conclude that canola oil used for cooking and included as a part of a normal diet, has negative effects. Not enough data to support that.
I don't buy the glyphosate fears, the data just isn't there to support it... at least not under the exposure levels that one would experience from eating food. Now farmhands ... that is another story since they are essentially bathing in the stuff.
I would be more easily convinced that the root cause of the issues people are attributing to glyphosate is actually derived from some entirely unconsidered source, then I would it being entirely derived from that particular compound. The initial studies done on it were fairly rigorous, and various followups throughout the years haven't been able to illustrate toxicity under normal exposure conditions.
I can't state unequivocally that it isn't bad either, as there are some clear situations where it definitely is. In fact there have been a few studies, looking at really high concentrations where toxicity WAS observed, but those studies were also not done in animal models (just on lab grown cells), and while interesting, experiments done on cells don't have the best carry over track record into a whole organism.
Indeed, I couldn't agree more. Truly this seems to be the solution to a good proportion of peoples ailments in life.
Thanks for giving the post a read and for the thoughtful reply man!
