Although arabinose is a low-calorie sugar with a small amount of calories, it is not calorie-free. Because of its structural characteristics, arabinose can inhibit the human body's absorption of sucrose, thus reducing the blood sugar response, which is suitable for people who control blood sugar and manage their weight. Zero-calorie sugar refers to those sweeteners whose calories are extremely low or even negligible. They produce little or no energy when metabolized in the body, such as erythritol and sucralose. These sweeteners are often labeled as "zero calorie" or "low calorie". Although arabinose also helps to inhibit the absorption of sugar, it does not belong to the category of zero-calorie sugar in terms of calories.
