Inulin Fiber: How to Utilize Its Benefits as a Prebiotic and Sugar Replacer

Inulin Fiber: How to Maximize Its Benefits as a Prebiotic and Sugar Replacer

Introduction

Is fiber becoming the new protein? You might think so. Fiber, after all, has long been connected with gut health. Whole grains and fruits, which are high in fiber, have long been used as traditional home treatments for constipation.

The Institute of Medicine’s Food and Nutrition Board even advises that individuals take 21 to 38 grams of fiber per day, depending on age and gender. Loren Cordain, Ph.D., a well-known paleo diet researcher, also supported this. He claims that ingesting a variety of vegetables, fruits, nuts, seeds, and additional fiber-rich foods makes it easy to meet the required level of fiber consumption.

In his study article, Cordain detailed the nutritional features of a modern diet based on anticipated paleo nutrient intakes. The diet was likewise significantly lower in total carbohydrate, but it supplied more fiber which is 42.5 grams.

One of the most common dietary fibers is inulin fiber. Like other fibers, it also has important health advantages such as boosting intestinal health, assisting in diabetic control, and aiding in weight loss.

What is Inulin Fiber?

Inulin fiber belongs to a class of dietary fiber known as fructans, which means it is a prebiotic that feeds the beneficial bacteria in the gut. It may also be found in a variety of plants where it is used to store energy, which is generally found in roots or rhizomes.

In 2018, inulin fiber was declared by the Food and Drug Administration in the United States as a dietary fiber additive that helps increase the nutritional value of manufactured food items. It has also been claimed that manufacturers add inulin to processed foods in order to increase the prebiotic content, substitute fat and sugar, and change the texture of the food.

Inulin fiber was discovered in 1804 by German scientist Valentin Rose. Through boiling-water extraction, he discovered “a unique compound” from inula helenium roots. Later on, British chemist James Irvine studied the molecular structure of inulin fiber using chemical techniques such as methylation. From there, he devised a method for isolating this new anhydrofructose.

In the 1930s, researchers were looking for a chemical that would act as a biomarker that would not be reabsorbed or secreted after being introduced into tubules. That was when inulin fiber was introduced because of its large molecular weight and resistance to enzymes.

Where Does Inulin Fiber Come From?

Inulin fiber is found naturally in over 36,000 plant species. Chicory roots, according to researchers, are the richest source of this dietary fiber. Other foods high in inulin fiber include Jerusalem artichoke, garlic, asparagus, raw onion pulp, wheat, and barley.

Inulin fiber can also be modified for commercial usage by manufacturers. It may also be purchased as a supplement or used as an ingredient in protein bars, cereal bars, beverages, baked goods, desserts, yogurts, and other milk products.

There are two types of manufactured inulin, which are chicory inulin and high-performance (HP) inulin. Fiber supplements that are linked to inulin are known as fructooligosaccharides or oligofructose.

What are the Uses of Inulin Fiber?

Inulin fiber is frequently used to treat or prevent digestive issues. In one research, elderly adults who consumed 20 to 40 grams of inulin fiber daily for a month experienced reduced constipation.

Furthermore, as a prebiotic, inulin fiber promotes the growth of beneficial bacteria in the colon. As a result, it may aid in the absorption of calcium and other minerals from diet, the maintenance of a healthy immune system, and the relief of digestive issues.

What are the Benefits of Inulin Fiber?

Inulin fiber has various nutritional and health advantages, particularly in the treatment of digestive problems and obesity.

Function as Dietary Fiber

Dietary fiber is regarded as an important component in the improvement of human health. That’s why, the emphasis on diet options rich in dietary fiber has increased. After all, its essential property includes being resistant to hydrolysis by gastric secretions. It is also easily absorbed in the small intestine while being fermentable by large intestinal microorganisms.

Inulin fiber is regarded as an important component of the dietary fiber complex and is labeled as such on food products. This is because it is a storage carbohydrate in plants with fructose moieties and is resistant to digestion in the small intestine. Furthermore, about 90% of the inulin travels to the colon and is processed by the bacteria that live there.

Caloric Value

The low caloric value of inulin fiber is attributable to its indigestibility when compared to its component monosaccharide moieties.
