But dozens of other sugar substitutes have been developed.
One class of sugar substitutes that seemed promising is a group called “sugar alcohols,” of which erythritol is a member. Sugar alcohols are sweet but are neither sugar nor alcohol. Sugar alcohols are derived from sugar, usually created by hydrogenating sugar or by fermenting it. Examples of sugar…
