Beta Glucan - Beta glucans are unique carbohydrates found in foods such as baker’s yeast, certain grains (barley and oats) and mushrooms. They are believed to possess an immune modulating effect in the human body. A recently published study in the Journal of Applied Research documents the ability of a beta glucan extract from baker’s yeast (Saccharomyces cerevisiae) to diminish the frequency of seasonal colds and flu. 40 healthy adults with ages ranging from 18 – 65 took a daily dose of 500 mg of this extract or a placebo. The treatment period coincided with the typical cold and flu season. Over the course of 12 weeks, those receiving the beta glucan supplement reported missing 0 days of school or work. The participants taking the placebo missed an average of 1.38 days. An improvement in “quality of life” and a lower likelihood of fever incidence and severity were noted in the beta glucan group as well. This led the authors of the trial to determine that this supplement may “reduce some risks associated with upper respiratory infections”. Successful studies from 2004 and 2008 provide a basis for these current findings. (4,5,6,7)
