I bought these because they were on sale and I wasn't allergic to them. I
think the whole wheat have 20 g of carbs per bun, minus whatever fiber is in
there. The multi-grain had a bit more.

I bought the whole wheat and used one for a sandwich. I found it to be
oddly sweet. Perhaps all whole wheat bread is sweet? I never buy that
kind. I just know I never liked the stuff. But they only had the two kinds
and this was lower in carbs.
