I checked the site you posted about Aspartame. Sweet'n Low is not Aspartame, and has been okayed by the FDA in recent years (if that means anything; sometimes it doesn't. LOL). The reason I have used it in moderation is because Dr. William Crook (pediatric allergist and yeast expert) suggested it in one of his books, in moderation. I've tried Stevia, but don't like the taste at all.
