Metabolic differences in the small intestine A. Metabolic genes as well as the associated reactions involved in the formation of glutathione (GSH) are presented. B, C Significant differences associated with (B) glycine and (C) glutamine are shown. Red and blue arrows indicate the significantly (Q‐value < 0.05) higher and lower expression of the metabolic genes in CONV‐R mice compared to GF mice, respectively. D. The levels of glycine, glutamine, and cysteine used in the de novo synthesis of the GSH are measured in the hepatic portal vein that conducts blood from the gastrointestinal tract to the liver tissue. *Q‐value < 0.05.

Human intestinal flora regulates the levels of the body’s main antioxidant, glutathione, which fights a host of diseases, new research confirms...

People fed beta-glucan-enriched pasta for 2 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.

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...
