I have noticed that most of the gf shopping lists do not include many
brands of olives, and yet it is difficult to imagine how gluten could
get into a jar of olives packed in brine.  Am I correct in assuming
that most brands of olives in brine would be ok, or am I missing
something?  I would be most glad of all comments, opinions, and
information about specific products.

Thanks in advance--I will summarize responses
