A new kind of pasta enriched with β-glucan increases populations of beneficial bacteria in intestinal tracts and reduces populations of non-beneficial bacteria. It also reduced low-density lipoprotein (bad) cholesterol, says an article in Applied and Environmental Microbiology, a journal of the American Society for Microbiology. β-glucans are healthy fibers that humans cannot digest but that can be digested by some species of our gut bacteria. They are special types of sugars that are found in the cell walls of certain microbes as well as in oats and barley. β-glucans are used clinically against diabetes, cancer and high cholesterol as well as to boost immune systems of people whose immunity has been compromised by radiation, chemotherapy, stress and other conditions.

The investigators also discovered an unanticipated rise in the concentration of certain short chain fatty acids, 2-methyl-propanoic, acetic, butyric and propionic acids, bacterial metabolites for which there is evidence of anti-inflammatory activity.

The β-glucan-enriched pasta was made from a mixture of 75% durum wheat flour and 25% whole grain barley flour. The daily dose of pasta, 100 grams, contained three grams of barley β-glucans, the recommended daily dose in the US and in Europe.
