Great question - we are thinking along the same lines. It's really just a general guideline about the fact that these foods that would normally have a natural amount of fat in it have to have the flavor replaced somehow when the fat is removed. Most food manufacturers do that with extra sugar, salt, or artificial "flavor" additives.

So of course, a carrot, which is naturally "low fat" wouldn't count toward what I'm saying here. Of course carrots are a healthy food even though they're low fat.
