A reduced carbohydrate ice cream or other frozen dessert product that contains a low-digestible sweetener system and a fermentable fiber material. The a low-digestible sweetener system consists of one or more low-digestible sweeteners having a molecular weight of from about 90 to about 190; and is typically a low molecular weight saccharide or a polyol. Typical low-digestible sweeteners include mannitol, maltitol, sorbitol, lactitol, erythritol, xylitol, isomalt, glycerin, talitol, mannose, tagatose, fructose, arabinose, fucose, lycose, ribose, sorbose, talose, and xylose, and mixtures thereof. The low-digestible sweetener replaces the digestible sugars to provide the appropriate freezing point depression of the product. The level of fermentable fiber is sufficient to mitigate a Taxation effect that can be caused by ingestion of the amount of the low-digestive sweetener. The fermentable fiber can be an inulin, a maltodextrin resistant to human digestion, an oligofructose, a fructooligosaccharide, a high water binding fermentable fiber, and a mixture thereof.
