Health Benefits of Rare Sugars
Rare sugars like allulose represent a paradigm shift in sweeteners—they may not just replace sugar's harm, but actively contribute to better health. This guide examines the research.

Main Examples:
- Allulose (D-psicose) - The most commercially available
- D-allose
- D-tagatose
- D-xylose
