Tagatose

An isomer of fructose marketed as a low-calorie sweetener under the trade name Naturlose.  Tagatose is a monosaccharide that’s approx. 92% sweet as table sugar (sucrose), but is poorly digested and absorbed.  Despite its potential, tagatose is still not widely used in the US, although that may change in the future – especially since it may have therapeutic applications for diabetes and digestive health.
