Definition of Allulose

Reviewed on 9/20/2021

Allulose is a monosaccharide, or simple sugar, that is absorbed by the body but not metabolized. Allulose is found in small quantities in wheat, jackfruit, figs, maple syrup, and other foods. It has been promoted as a substitute for sugar because it is low in calories and has 70% of the sweetness of sucrose (sugar). Possible side effects of consuming allulose can include abdominal discomfort and increased passing gas. The U.S. FDA has approved the use of allulose as a sugar substitute. Another name for allulose is d-psicose.
