Explanation

Erythritol is indeed a sugar alcohol, which is a type of carbohydrate. It is commonly used as a low-calorie sweetener because it tastes sweet like sugar but has fewer calories.

Why Erythritol is Used:

  • Low-Calorie Sweetener: Erythritol provides sweetness with almost no calories, making it popular in sugar-free and low-calorie foods.
  • Noncariogenic: This means it does not cause cavities, which is beneficial for oral health.

How It Works:

  • Erythritol is absorbed in the small intestine and mostly excreted unchanged in urine, which minimizes its impact on blood sugar levels.

Benefits:

  • It does not contribute to tooth decay and has been studied for its potential positive effects on oral health.

In summary, erythritol is a sugar alcohol that offers a sweet taste with fewer calories and is friendly to teeth, making it a popular choice for those looking to reduce sugar intake.
