you need to have your setting on NET CARBS and then carefully select the options when you search. I have found most of the bars with the sugar alcohol added as fiber to give a true Net count.
Absolutely follow Monika's advice. Be careful when you select the food to enter!! Watch your entries each and every time you enter it, as people can often get in a tug-of-war over the handling of sugar alcohols, changing the database first one way, and then another.
While there are entries that combine the SAs with the fiber so that BOTH total and net carbs are correct (but fiber is overstated), there are also other entries that show reduced TOTAL carbs with correct fiber. This latter method still gives you the correct NET carbs but can vastly understate the TOTAL carbs....and TOTAL carbs can become important to you in certain circumstances, even though one primarily focuses on net carbs.
I always set up my own custom food entry, that I do not share with the database, for any product that contains SAs, setting it up the way I want (adding the SAs to the fiber count). That way I don't have to worry about "my" product getting caught up in that tug-of-war.
