While reading the March issue of Low Carb Energy magazine, I came
across an article by Dr. Fred Pescatore regarding common myths about
fat. According to him, canola oil is the most unhealthful oil on the
market because it contains from 5 to 15 percent trans fat right out of
the bottle. This, if true, is quite a shock! He says the trans fats
are generated from the processing of the rapeseed to make it into
canola oil.
I looked at a bottle of Wesson canola oil and like most products, it
doesn't say anything specifically about trans fat content. On the
other hand a bottle of the local supermarket house brand canola oil
says it has no trans fats. So, apparently there is some disagreement
here.
Searching the web, I found some links that at least partially support
the Dr's claim:
http://www.tfx.org.uk/page13.html
http://www.hc-sc.gc.ca/english/media/releases/2004/trans_fats-gras_e.html
The second website says processed vegetable oils in general, including
soybean oil and canola oil, contain up to 2.5% trans fat.
Of course that's still a long way from the 5 to 15% claimed in the
magazine article. Most other health websites endorse canola oil as one
of the better oils and say nothing negative about it.
Anyone else ever hear this or have any more info?
