Allulose is a type of sugar that is similar to fructose. Unlike other sugars though, Allulose only contains 0.4 calories per gram in comparison to the 4 calories per gram that sugar contains. Additionally, while the body absorbs allulose it does not metabolise it into glucose, so it is virtually calorie free.
Allulose can come granulated or powdered forms and like other Keto sweeteners such as Erythritol, is 70% as sweet as sugar. According to the FDA, allulose has little to no effect on blood glucose or insulin levels.
This makes Allulose an excellent sweetener for people who have diabetes, high blood sugar, metabolic disorders or on a Keto diet.
