What Is Allulose? The Complete Guide
What is allulose? Allulose is a rare natural sugar that is transforming the sweetener industry. It delivers a taste and baking experience remarkably similar to regular sugar, yet with 90% fewer calories and zero blood sugar impact. Allulose calories clock in at just 0.4 per gram, making it the ideal sugar replacement.
What Is Allulose?
Allulose (D-psicose) is a rare monosaccharide found naturally in small quantities in wheat, figs, raisins, and maple syrup. While chemically similar to fructose, your body processes it completely differently.
Key Properties:
- Calories: Only 0.4 per gram (90% fewer than sugar)
- Glycemic Index: 0 (no blood sugar spike)
- Sweetness: 70% as sweet as sugar
- Taste: Clean with no aftertaste
- Function: Browns, caramelizes, bakes like sugar
How Your Body Processes Allulose
Unlike regular sugar, allulose is:
- Absorbed in your small intestine but not metabolized
- About 70% excreted unchanged through urine
- Remaining 30% fermented by gut bacteria
- Results in zero blood sugar or insulin response

Baking with Allulose
Why Its Superior
Allulose uniquely replicates sugars functional properties:

Conversion Ratios
- For equal volume: Use 1:1 substitution

Tips for Success
- Reduce liquids slightly (allulose adds moisture)
- Lower oven temp 25°F (browns faster)
- Watch baking time carefully
- Let baked goods cool completely (texture improves)
