How Dietary Fibers Differ

Dietary Fiber Word Cloud

Fiber is the structural component that makes up the thick cell walls of various plants, and it’s a complex carb that is indigestible. Two different types of fiber exist: soluble fiber and insoluble fiber. Neither type of fiber is digestible, so your body doesn’t absorb it the way it does carbs, proteins, and fats. Here’s a closer look at the difference between these types of dietary fibers and how they function in your body.

Soluble Fiber

Soluble fiber is dietary fiber that dissolves in water, and studies show that it can lower cholesterol and blood sugar levels. You’ll find soluble fiber in foods like apples, blueberries, nuts, oatmeal, and beans. This fiber can keep you feeling full, aiding in weight loss, and can also help you have healthy bowel movements, preventing problems with diarrhea and constipation.

Insoluble Fiber

Insoluble fiber does not dissolve in water, and it helps to increase the bulk of your stool, helping food move through the digestive system. Products that contain insoluble fiber include wheat bran, whole-wheat flour, brown rice, fruit skins, and seeds. This type of dietary fiber is also great for aiding in weight loss and improves digestive health.

The Function of Dietary Fibers

When you eat dietary fibers, they have three functions, including fermentation, viscosity, and bulking. The microorganisms that are found in your large intestines consume fermentable fibers. Viscous fibers help to reduce the absorption of cholesterol and reduce the sugar response of the body after you eat. Bulking dietary fibers help to increase the weight of stool, improving regularity. 

Getting plenty of dietary fiber in your diet is important if you want to lose weight. Dietary fibers make you feel full, they aid in digestion, and they offer many great health benefits, making them a great addition to a healthy, well-rounded diet.
