People talk a lot about stevia, and it's prominently displayed on packaging, but then when I look at the ingredients, the sweetener is actually mostly sugar alcohols. Is stevia ever used alone? If it's just a "fig leaf" so to speak, then perhaps the health effects of the sugar alcohols would be more relevant.
