Erythritol is a sugar alcohol used as a low-calorie sweetener. It is naturally found in some fruits and fermented foods. Erythritol has about 70% of the sweetness of sugar but contains only 0.24 calories per gram, making it a popular choice for those looking to reduce sugar intake without sacrificing sweetness. Unlike regular sugar, erythritol does not raise blood sugar levels, making it suitable for people with diabetes. It is also less likely to cause digestive issues compared to other sugar alcohols. Erythritol is often used in sugar-free products, including candies, baked goods, and beverages.
