Which type of dietary fiber dissolves in fluids?

Soluble dietary fibers are characterized by their ability to dissolve in water. This soluble form of fiber forms a gel-like substance in the digestive tract, which can help to slow down digestion and improve the absorption of nutrients. Soluble fibers can also aid in managing blood sugar levels and lowering cholesterol by binding to these substances in the digestive system and helping to remove them from the body.

Common sources of soluble fiber include oats, beans, lentils, fruits such as apples and oranges, and some vegetables. This type of fiber is particularly beneficial for heart health and can promote a feeling of fullness, which may assist with weight management.

In contrast, insoluble dietary fibers do not dissolve in water and primarily contribute to the bulk of stool, aiding in maintaining regular bowel movements. Vitamins and proteins are macronutrients and micronutrients, respectively, that serve different functions in the body unrelated to fiber types.
