Looks like bad news:
http://www.livestrong.com/article/253042-which-sugars-does-carob-contain/
I got here by googling " fructose in carob bars "
Quote:
Carob contains 55 to 75 percent sucrose.
Carob contains 7 to 16 percent fructose.
Try 85% cocoa chocolate bars in small doses. It's about 15% "sugars"
