Gut microbiota tagged posts

Recent research has found that changes in the gut microbiota — the trillions of bacteria and other microbes that live in the intestines — can alter the brain and behavior. Now, a study led by scientists at UCLA could elucidate how and why that phenomenon occurs.

In the experiment, which was conducted with mice, researchers found that gut microbes can exacerbate the effects of cognitive impairment because of how they affect the hippocampus, the region of the brain that is critical for memory and learning...

Differences in gut microbial composition correlate with regional brain volumes in irritable bowel syndrome. Microbiome, 2017; 5 (1) DOI: 10.1186/s40168-017-0260-z

A new study at UCLA has revealed 2 key findings for people with irritable bowel syndrome about the relationship between the microorganisms that live in the gut and the brain. For people with IBS research shows for the first time that there is an association between the gut microbiota and the brain regions involved in the processing of sensory information from their bodies. The results suggest that signals generated by the brain can influence the composition of microbes residing in the intestine and that the chemicals in the gut can shape the human brain’s structure.

Additionally, they gained insight into the connections among chi...

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...
