Erythritol does not stimulate the release of satiety hormones, while classic sweeteners such as sucrose and sucralose do, according to a study by Maastricht University. Even when enough erythritol was used to have an equal sweetness to sucrose and sucralose, the erythritol did not stimulate hormones associated with the feeling of fullness.
Erythritol is a type of sugar alcohol, which is a sweetener that has fewer calories than sugar. Sugar alcohols are found in sugar-free treats because they sweeten foods but are technically not sugar. The benefit of sugar alcohols is that they have significantly fewer calories and do not make blood glucose levels rise as drastically as sugar.
While sugar alcohols have fewer calories and provide a sweet taste to food, they are not necessarily healthy. Sugar alcohols are difficult for the body to digest, which means that some people experience gastrointestinal issues after consuming them. Similarly, because they pass through the body largely undigested, they do not stimulate satiety hormones as efficiently as sugar. This means that if a food is sweetened with sugar alcohols such as erythritol, individuals need to eat more of that food to feel as full as they would with a smaller portion of food sweetened with sugar.
