Re: Dangers of canola oil

HI Adeline,

You have asked and interesting question and you are partially correct in 
your thinking. The concern with canola oil, which was isolated from earlier 
varieties, was the content of both erucic acid and glucosainolates (can 
cause hypothyroidism & thyroid enlargemen). Today canola oil is the seocnd 
most popular edible oil in world production. New varieties have been breed 
to contain only small amounts of erucic acid and glucosainolates.
I hope this anwers your question.

Sincerely,
