Which substance is a sugar that aids in digestion?

Fructose is a type of sugar that is not only naturally found in fruits but also plays a role in the digestive process. It is a monosaccharide, which means it is one of the simplest forms of sugar, and can be easily absorbed by the body. Fructose can contribute to the body's energy supply and is also a substrate for certain metabolic pathways.

In digestion, fructose can have a prebiotic effect, promoting the growth of beneficial gut bacteria. This is significant as a balanced gut microbiome is essential for overall digestive health. While other sugars like galactose, glucose, and mannose are important for various bodily functions and can contribute to carbohydrate metabolism, fructose's specific role in aiding digestion, particularly through its impact on gut health, distinguishes it in this context. This metabolic versatility and the ability to support digestive processes make fructose a notable sugar contributing to digestion.
