Broadly, dietary fiber is divided into two types, each with different characteristics: soluble fiber and insoluble fiber. Some fiber, like psyllium, can also give you important health benefits. Depending on subtle variations in hemicellulose structure, hemicellulose can either be soluble or insoluble. It contains mucilage, gums, and pectin, which soothe the gut mucosa and increase the production of SCFA-producing gut bacteria. Dietary fiber is a part of food that human digestive enzymes can’t break down. By stimulating the growth of beneficial intestinal microorganisms, prebiotics offer a host of downstream health benefits, which I will discuss in more detail shortly. (35) Fascinating research also suggests that resistant starch alters the gutâbrain axis, at least in non-human animals. However, a crucial difference between starch and fiber is that our digestive enzymes can break down the glycosidic bonds between the glucose units of starch, making the glucose available to our bodies as energy. 1998;128:714-9. Chitin is a unique fiber that is not commonly found in the Western diet. In some individuals, temporarily limiting FODMAP-containing foods in the diet can alleviate symptoms while the underlying causes of the dysbiosis are being treated. Fiber can also be classified as fermentable versus non-fermentable.
Soluble fiber absorbs and dissolves in water during digestion, turning into a gel-like consistency. Dietary fibre content in wheat or millet based diets are higher than in a rice based diet. If fiber can dissolve in water it’s considered soluble— otherwise, it’s considered insoluble.
Fiber is found almost exclusively in fruits, vegetables, tubers, grains, and legumes. Soluble fiber and insoluble fiber work in different ways in the body, but do their best work when they are teamed together. Two Types of Dietary Fiber | Soluble Fiber & Insoluble Fiber.

In the nutrition communityâs attempts to understand fiber, weâve broken down the types of dietary fiber into several categories. (55, 56). Dietary fibers, starches, and prebiotics work together to support a healthy gut ecosystem.

Background: Mounting evidence, yet with varying levels of proof, suggests that dietary fibers (DFs) may exert a protective role against various chronic diseases, but this might depend on the DF type and source. If youâre feeling adventurous, cricket flour is a rich source of chitin that you might consider incorporating into your diet!
