22 Sep 2015 --- People fed β-glucan-enriched pasta for two months showed increased populations of beneficial bacteria in their intestinal tracts, and reduced populations of non-beneficial bacteria. They also showed reduced LDL (“bad”) cholesterol. This work is part of a broad effort to identify potential prebiotics--foods that could encourage the growth of health-promoting bacteria in the gastrointestinal tract. The research is published in Applied and Environmental Microbiology, a journal of the American Society for Microbiology.
