Beta Glucan is a soluble dietary fiber found naturally in cereal grains, yeast, and in medicinal mushrooms (cordyceps, reishi, shitake, and maitake). Among its sources, barley has the highest Beta Glucan content. Beta Glucan is a polysaccharide that promotes good health by reducing cholesterol, and controls blood sugar levels. Beta Glucan lowers blood cholesterol by preventing the absorption of cholesterol from food in the stomach and intestines. If injected, Beta Glucan stimulates the immune system by growing chemicals which prevent infection. Beta Glucan also helps with constipation and bowel issues, preserves healthy intestinal bacteria, and helps regulate weight.
Inulin is a soluble fiber found in 36,000 plant species (wheat, onion, banana, garlic, asparagus, etc.) and in some bacteria and fungi. The chicory roots are the richest source of inulin. Several manufactured forms of inulin are Chicory inulin and High-Performance (HP) inulin. In 2018 the FDA approved inulin as a dietary fiber component used to increase the nutritional value of processed food products in the United States. Inulin stimulates growth of beneficial bacteria, which in turn helps improve bowel function and gut health, curb appetite, and boosts immunity.
Xanthan is an indigestible soluble fiber, which absorbs water and turns into a gel-like substance, slowing down digestion. It controls sugar entry to the bloodstream and decreasing blood sugar spikes. Xanthan aids in weight loss by increasing satiety, lowering bad cholesterol, claiming to have cancer-fighting properties, improving regularity, and used as saliva substitute.
Konjac Glucomannan is a soluble, fermentable, polysaccharide produced from the Amorphophallus Konjac (elephant yam or konjac plant) found in Asia. Konjac is available as supplements, in drink mixes, additive (emulsifier and thickener) to food products such as flour and pasta.
