Oat beta-glucans
One exceptional soluble fibre is beta-glucan, a natural, indigestible polysaccharide found in oats, barley, yeast, bacteria, algae, and mushrooms. Oats are particularly rich in beta-glucan, with concentrations ranging from 3-5% depending on the variety. Oat bran, produced by removing the starchy content of the grain, contains the highest concentration of beta-glucan, offering numerous health benefits for cardiovascular health⁵ ⁶, glycaemic response⁷ and the gut microbiome.⁴
