What is the approximate energy content kcal and g of most sugar alcohols?

Sugar alcohols, also called polyols, are a group of carbohydrates that have a structure similar to sugars but contain fewer calories. They are often used as sweeteners in low-calorie foods and beverages.

The energy content of most sugar alcohols is approximately 2.4 kcal/g, which is about half the energy content of sugar (sucrose), which has an energy content of approximately 4 kcal/g.

In terms of grams, the amount of sugar alcohol needed to provide the same sweetness as sugar varies depending on the specific sugar alcohol. For example, xylitol has a sweetness level that is approximately equal to that of sugar, so 1 gram of xylitol provides the same sweetness as 1 gram of sugar. However, erythritol has a sweetness level that is approximately 70% that of sugar, so 1.4 grams of erythritol are needed to provide the same sweetness as 1 gram of sugar.
