Rapeseed Strikes Again

We are weak beings. At least I am from time-to-time. I had a real craving for a takeaway curry last week and caved. Not only was the curry terrible in the end, I’m sure it was cooked with rapeseed (aka canola oil). Worse still, the next day I was at a golf outing and some chicken wings were served afterwards. They were delicious but likely deep fried in rapeseed.

My stomach was certainly not 100% after these meals and my blood glucose was higher than one might expect. I’m guessing the rapeseed oil caused some inflammation which helped spike my sugar.

I should know better. Despite returning to my healthy habits, my morning readings were still higher than they have been for the last three months. I blame the rapeseed…and me of course.

For those not in the know, rapeseed oil is toxic without heavy processing. Here is a rapeseed crushing plant in Canada:

Moreover, a lot of rapeseed oil comes from genetically modified rape.

Better health minds than mine have written about the dangers of rapeseed. Dr Mercola notes that

“Canola oil is not healthy fat vital to your brain; it is manufactured from genetically engineered rapeseed plants altered to reduce levels of erucic acid toxic to humans and processed through several chemical baths before being bleached.”

For you trivia buffs, you’ll be keen to know that canola started out as a motor lubricant!

My guru Mark Sisson also discusses the problems associated with rapeseed/canola here.

Finally, there’s a very detailed article explaining the history of canola here along with its many unhealthy properties. Here’s a key quotation

“The [rapeseed] oil is removed by a combination of high temperature mechanical pressing and solvent extraction. Traces of the solvent (usually hexane) remain in the oil, even after considerable refining. Like all modern vegetable oils, canola oil goes through the process of caustic refining, bleaching and degumming–all of which involve high temperatures or chemicals of questionable safety. And because canola oil is high in omega-3 fatty acids, which easily become rancid and foul-smelling when subjected to oxygen and high temperatures, it must be deodorized.”

Finally, one of the more alarming things I took from the last article was this chart which shows how rapeseed is processed:

I’m on a two-day fast to get myself back on the straight and narrow.
