Betaglucans are the soluble fraction of dietary fibre and belong to the group of polysaccharides. They can be found in the wall of some bacteria or yeast, but are also present in cereals such as wheat, rye and oats. The effects of betaglucans on our body are based on their action in helping to regulate blood glucose levels or lower cholesterol. In addition, they show a strong immunostimulating and antibacterial effect, which also accounts for the preventive and positive effect of this nutrient on our body.
