Mustard oil is widely used in cooking in some parts of the world
(such as India).  It is pressed from mustard seeds, which I
believe are considered paleo.  This implies that the pressed oil
should be considered paleo as well.  In light of the recent
discussion about canola oil, which is basically a variant of
mustard oil, I thought it would be useful to check the erucic
acid content of mustard oil, since EA is supposed to have harmful
effects.  The EA content of mustard oil turns out to be quite
high, about 41g/100g!  By comparison, canola oils EA content is
.6g/100g.  Whole mustard greens contain .058g/100g.  Macadamias
also contain .23g/100g.

I'm not sure what to make of this, but if alexs's comment that no
safe levels of EA have been determined, then perhaps that is a
good reason to avoid all these foods, paleo or not.
