Maybe too much Canola oil in the diet or exposed to too much mustard crop? In Britain animals eating pressed rape seed eventually lost the ability to stand and had seizures. Something in rape seed oil, delaminated their nerves. Erucic acid? They Claim to have bred it out of Canadian Rapeseed making it safe for us but I don’t trust them. Canola oil goes rancid quicky in any case. Cheap, and they sneak it into everything.
I did a whole research project on fats and oils a decade ago-I do not remember the details.
Bottom line though was that Canola Oil is NOT healthy and should not be used-except maybe in lamps. Ha.
