Hi Melodie. The reason is this: there's a loophole in the labelling laws. It allows for the sugar alcohols to *not* be counted as a carbohydrate, even though there's considerable debate about how the body metabolises them. Some people get the same blood sugar surge (and probably therefore insulin surge) that they'd get from sugar. Other people don't. It's a YMMV thing. For more details, check the "truth about low carb sweeteners info" link under "quick links" on the tool bar over to the right --> .

Most people have more success if they avoid them.
