Allulose is a low-calorie epimer of fructose, used by food and beverage manufacturers as a low-calorie
sugar replacement. Allulose is naturally found in foods such as kiwi, raisins, figs, wheat, and maple
syrup in small quantities, but is produced commercially via the enzymatic conversion of fructose.
While technically a "rare sugar," allulose is 60-70% the sweetness of sugar, and contributes only 10%
of the calories (0.4 kcal/g) and does not impact blood glucose levels. Due to the potential benefits
to the food industry and supporting evidence, in October 2019, the FDA exempted allulose from
labeling as an Added on the nutrition facts panel.
