I would have to agree with litespeed about ignoring the majority of protein bars on the market. Personally i have never even been tempted to eat one.
One little comment in your post concerned me though. You say you avoid saturated fat. Why? I understand that saturated fat has important role to play in a healthy and balanced diet. It has been said by some of the nutrition gurus who write for this site that one third of your daily fat intake should come from saturated fat.
