“The most promising trend in food science & technology in recent years is the use of prebiotics to regulate the population of gut bacteria and confer health benefits in diabetes, obesity, and even cancer. Important sources of prebiotics in medicinal mushrooms are unique indigestible fibers, which are often called polysaccharides, that are known to inhibit the growth of pathogens (harmful bacteria) by increasing the growth of probiotic (friendly bacteria) in the gut.”
