Why allulose can skip "sugar" on the label but not "carbohydrate"

What exactly did the FDA decide?

In its October 2020 final guidance ("Guidance for Industry: The Declaration of Allulose and Calories From Allulose on Nutrition and Supplement Facts Labels"), the FDA exercised enforcement discretion to exclude allulose from the "Total Sugars" and "Added Sugars" declarations on the Nutrition Facts label. It also permits a reduced calorie factor of 0.4 kcal/g for allulose, versus the standard 4 kcal/g used for sucrose and most sugars.

So does allulose disappear from the label entirely?

No. It still counts toward "Total Carbohydrate." The FDA's decision applies specifically and only to the Total Sugars / Added Sugars lines, not to Total Carbohydrate. A product can legitimately show a low "Total Sugars" figure while still carrying a meaningful Total Carbohydrate count from allulose.

Does this mean allulose has zero blood-sugar effect?

No. This is a labeling-enforcement decision, not a metabolic claim. Allulose has a low but non-zero measured glycemic and insulinemic response in the rare-sugar research literature reviewed here, meaningfully different from erythritol's near-total non-absorption (about 90% excreted unchanged). RecipeMend still buckets allulose as low-impact for blood glucose, but flags this distinction explicitly rather than treating all non-nutritive sweeteners as identical.

Does allulose bake like sugar?

Allulose bakes closer to sugar than most alternatives. It participates directly in Maillard browning as a reducing sugar, and can actually brown faster and darker than table sugar at the same oven temperature. Common guidance is to drop the oven temperature about 25 to 35°F and watch closely near the end of the bake to avoid over-browning. See the allulose browning fix guide for the full troubleshooting steps. The swap ratio is about 1⅓ cups allulose per 1 cup sugar, since allulose is roughly 70% as sweet by weight. Unlike erythritol, it carries no cooling effect, which makes it a useful partial swap for blending down a cooling aftertaste in an erythritol-heavy bake.

Why doesn't allulose count as 'sugar' on a Nutrition Facts label?

In October 2020, the FDA issued final guidance exercising enforcement discretion to exclude allulose from the 'Total Sugars' and 'Added Sugars' lines on the Nutrition Facts label. This is a labeling-enforcement decision, not a claim that allulose has zero metabolic effect.

Does allulose still count as a carbohydrate?

Yes. Allulose still counts toward 'Total Carbohydrate' on the label, and the FDA allows a reduced calorie factor of 0.4 kcal/g for it instead of the standard 4 kcal/g used for sugars, reflecting its low but real caloric contribution.

Does allulose raise blood sugar?

Allulose has a low but non-zero measured glycemic and insulinemic response in the rare-sugar research literature reviewed for this database. It is not glycemically identical to erythritol's near-total non-absorption, and this database keeps that distinction explicit rather than treating all non-nutritive sweeteners as equivalent.
