There may be a new non-caloric sugar substitute showing up in stores in a couple years. It is called allulose (aka psicose). This is a natural sugar and apparently the company Tate & Lyle have figured out how to make the produce in large quantities. When consumed allulose is excreted in the urine before it reaches the bowels, therefore avoiding the problem caused by other sugar substitutes that get to the large intestine where it is fermented by bacteria.

Very cool! Thanks for sharing!
