Beta glucan is a carbohydrate found in oats, barley and yeast, for example. Beta glucan derived from oats and barley helps to lower your blood cholesterol. The (1.3)-(1.6)-beta-D-glucan in baking yeast affects your body’s defence mechanisms in several complex ways.
In vitro observations prove that beta glucan activates the immune response. In preliminary clinical studies, intake of beta glucan for 16 weeks significantly reduced incidences of the common cold and its severity compared to the placebo. Beta glucan also affects your blood sugar levels.
