What is the term for fiber that dissolves in water and is easier to digest?

Soluble fiber refers to the type of dietary fiber that dissolves in water, forming a gel-like substance in the digestive tract. This characteristic allows soluble fiber to slow down digestion, leading to improved nutrient absorption. Soluble fiber can be found in foods like oats, beans, fruits, and vegetables, and is known for its benefits in helping to regulate blood sugar levels and lower cholesterol.

In contrast, insoluble fiber does not dissolve in water and adds bulk to the digestive system, which aids in promoting regular bowel movements. Functional fiber is a category that includes fibers that have been extracted and added to foods, while enhanced fiber is not an established category in nutritional terms. Thus, soluble fiber stands out due to its unique properties and health benefits related to digestion and metabolic health.
