I'm always on the hunt for low sugar protein bars. CarbRite is one brand that's lower in sugar and recognizable ingredients and decent carb/protein/fat rations. Hard to find, though. I found them by accident at a discount vitamin/supplement store. I don't really eat many protein bars, though because of all of the crappy ingredients (some are just like candy bars, except for a little extra protein!)but I do keep some of the aforementioned in my car for emergencies.
