@gollum,
None that I'm aware of, except possibly a higher price.
Somehow, though, their inclusion seems to give the impression that the stuff passes through the system with no effect on anything. It's kind of like a pie that claims "Naturally sweetened". That usually means it's sweetened with pineapple juice, which is "natural". Then there's the label that says "No sugar added". The last thing on earth that might mean is sugar free.
