Erythritol is a polyol, also known as sugar alcohol, and serves as an excellent substitute for conventional white sugar. It is obtained through fermentation of fruits and other foods, which gives it a very favorable nutritional profile. This sweetener is unique among sugar alcohols as it contains no calories and does not alter blood glucose or insulin levels, making it suitable for diabetics. Additionally, erythritol helps prevent dental cavities and is less likely to cause digestive issues compared to other sweeteners. It is an ideal product for those following ketogenic diets, allowing sweetness without adding calories.
