I googled is rape seed digestible
which is the point of your question - not recognised as fat
and not surprisingly the answer is yes it is digestible

no one has made the point about erucic acid - the stuff that cured Lorenzo in Lorenso's oil - crap of course - Lorenzo died in real life
and that for the rest of us should be LOW -
and if rapeseed fat is not recognised where does it go?
I didnt bother with that one - as it is recognised
There was a fad ( geddit?) twenty years ago about non digestible fat which didnt catch on because - - - you got in exchange fatty diarrhoea ( so THAT is where it ended up!)- steatorrhoea and everyone found that MUCH worse
so in chort- - - is it OK to eat fat because I have labelled it non-fat?
n o it is not OK
