Lactitol is a type of sugar alcohol that is commonly used as a low-calorie sweetener in various food products. Although lactitol is the most common name used for this ingredient, there are other synonyms that can be used as well. Some of the most common synonyms for lactitol include erythritol, xylitol, sorbitol, and maltitol. These sweeteners are often used in place of sugar or other high-calorie sweeteners in various recipes to reduce calorie intake while still maintaining sweetness. It is important to note that while these sweeteners are considered low-calorie alternatives, they should still be consumed in moderation to ensure a healthy diet.
