Allulose is a new low-calorie sweetener that looks and tastes like actual sugar but has only 1/10th the calories of sugar. This means 1 tablespoon of allulose has anywhere between 4-4.8 calories.
It also doesn’t have the bitter or weird aftertaste like some other sweeteners.
Not only that, Allulose has the almost same chemical formula as table sugar but our body doesn’t metabolize it, so it’s not converted into glucose. This is why it’s calorie-free.
Allulose is eliminated via urine within a few hours of consumption (Tsukamoto et al. 2014).
Wikipedia describes Allulose as a “low energy monosaccharide sugar present in small quantities in natural products”.
The scientific name of Allulose is D-Psicose (or D-Allulose).
Where does Allulose come from?
Although it’s becoming popular now, Allulose was first identified in wheat more than 70 years ago. It’s also found in small quantities in Maple syrup, Jackfruit, figs, raisins.
There’s a good chance you’ve come across Allulose because of QuestNutrition bars and/or Ketogenic diet, but the mass production of Allulose was first discovered in 1994 by professor Ken Izumori at Kagawa University in Japan.
It’s a naturally occurring sugar, made from fermented corn.

How do you work out the Net Carbs of Allulose in a food product?
From the nutritional facts section, subtract any listed fiber from the total Carbohydrates. Then subtract half of any sugar alcohols listed on the label. If Erythritol is the only sugar alcohol listed, you can subtract all of it to get the total net carbs. Read more about Net carbs.
This is why Quest bar Net carbs are a lot lower.
Here is a sample calculation from the birthday cake quest bar:
Total Carbohydrates: 25g
Dietary fiber: 14g
And this is why it has its total Net Carbs as 5g.
