A rare natural sugar called allulose just got a favorable nod from U.S. regulators that could give a boost to companies like Ingredion and breakfast-cereal subscription startup Magic Spoon.

The Food and Drug Administration issued draft guidance on the sweetener on Wednesday, saying itโ€™s the first time the agency intends to โ€œallow a sugar to not be included as part of the total or added sugarsโ€ categories on food labels.

โ€œThe latest data suggests that allulose is different from other sugars in that it is not metabolized by the human body in the same way as table sugar,โ€ FDA food-safety official Susan Mayne said in a statement. โ€œIt has fewer calories, produces only negligible increases in blood glucose or insulin levels, and does not promote dental decay.โ€

Ingredion in December reported a pact with Japanโ€™s Matsutani Chemical Industry Co. to make Astraea Allulose in Mexico and market it in the Americas.

Allulose is used to help sweeten Magic Spoon, which is being pitched as a โ€œhealthy cerealโ€ thatโ€™s โ€œperfect for anyone on a ketogenic or low carb diet.โ€ The sweetener is found in things like figs and maple syrup, according to the Magic Spoon website.
