Yes. In a one-teaspoon serving, allulose contains 4 grams of total carbs. Allulose net carbs clock in at 0 grams.
Since the body does not absorb allulose carbs like those in regular sugar, they can be subtracted from the total carb count.
According to the Food and Drug Administration (FDA), allulose provides about 0.4 calories per gram (g), which is significantly lower than the 4 calories per g in sugar. In addition, the body absorbs allulose but does not metabolize it into glucose, so it is virtually calorie free. According to the FDA, allulose has little to no effect on blood glucose or insulin levels.
Scientists can produce allulose in the laboratory, but it is also found naturally in some foods, such as dried fruits, brown sugar, and maple syrup.
Other names for allulose include psicose, d-psicose, d-allulose, or pseudo-fructose.
When calculating net carbs, allulose is subtracted from total carbohydrates because it is not metabolized and therefore causes no increase in blood glucose or blood insulin levels (International Food Information Council).
According to the FDA, people may experience some abdominal discomfort from consuming large quantities of allulose, but this side effect is not toxic and usually temporary.
In one study, researchers investigated the possible side effects of consuming allulose occasionally or regularly. People reported abdominal side effects when consuming increasing doses of allulose, including:
