It has taken me 6 years to work out that it is rapeseed oil that is instrumental in my migraine attacks, within 12 hours of having anything with this oil in I will have a migraine. There are many foods on the supermarket shelves that have this oil in their ingredients ,I have found, biscuits, breads, ready meals, frozen meals, and then of course eating out!
This oil is called 'Canola oil' in the states and Canada (wherer it got it's name change), and there is a wealth of information about it on a fantasticlly informative and scientifically based website in the states called Weston price http://www.westonaprice.org/know-your-fats/
Here you'll find an article 'The great Conola' http://www.westonaprice.org/health-topi ... t-con-ola/
and you'll see that this oil used to be used to oil steam engines , and contains erucic acid, albeit this element has been reduced to 'acceptable levels' by a form of genetic manipulation and seed splitting.
anyway, it is definitely a problem for me, and I wonder if anyone else has this connection between Rapeseed oil and Migraine?
