For those of you who live near a grocery run by Kroger's (including Ralph's, King Soopers, Smith's, Frys, Dillons, and others), look for their Private Selection brand in the bread dept. They have a Sugar Free 100% Whole Wheat that is really good. Pictured is the nutrition label. It is sweetened with maltitol which is first among the sweet ingredients on the label. It also has a small amount of raisin juice concentrate and sucralose. The sucralose is the next to last ingredient so I can't believe there could be very much.
Pro's: high fiber, good tasting, filling
Con's: may not be widely available, tiny bit of sucralose
