Gut microbes that convert sugar into vital short-chain fatty acids point the way to novel therapeutics
by Kobe University A Kobe University team found that glucose is excreted into the small intestine, where bacteria transform it into short-chain fatty acids. Credit: Kobe University Gut microbes that were thought to feed exclusively on dietary fiber also get fed sugar from our guts, from which they produce short-chain fatty acids that are crucial to...

Gut microbes’ surprising connection to anxiety point toward a potential probiotic solution
by Duke-NUS Medical School Credit: Unsplash/CC0 Public Domain Could the key to easing anxiety be hidden in our gut? Scientists from Duke-NUS Medical School and the National Neuroscience Institute have discovered a crucial connection between gut microbes and anxiety-related behavior. Their research, published in EMBO Molecular Medicine, suggests that microbial metabolites—specifically indoles—play a direct role in regulating brain...

Study reveals how beneficial gut microbe breaks down mucus for health
Reviewed University of BirminghamJan 31 2025 A microbe found in the lower part of the gut that is associated with good health has been comprehensively analyzed and found to have a focused diet breaking down sugars locked away in mucus. The new study, published in Nature Microbiology today (Friday 31 January) is a complete systematic analysis of...

Gut microbiome changes during pregnancy may influence immune system response
by American Society for Microbiology Credit: Pixabay/CC0 Public DomainDuring pregnancy, a woman’s immune system changes dramatically but researchers don’t yet understand all the underlying mechanisms. A new study shows how the gut microbiota may play a role. In a paper published in mSystems, researchers in China report that during pregnancy, changes in levels of cytokines—immune system...

Researchers discover associations among PTSD, diet, and the gut microbiome
by Brigham and Women’s Hospital Credit: Pixabay/CC0 Public DomainThe human gut microbiome has a significant impact on our health. Research has shown that it can influence the development and response of emotions, but the relationship between post-traumatic stress disorder (PTSD) and the gut microbiome has been unexplored. PTSD is a fear-based mental health disorder that develops...

How a gut microbe can exacerbate obesity
by RIKEN Graphical abstract. Credit: Cell Metabolism (2023). DOI: 10.1016/j.cmet.2022.12.013 RIKEN researchers have discovered how a species of gut microbe exacerbates obesity in mice fed a high-fat diet. Now published in Cell Metabolism, this finding could help scientists develop new ways of treating obesity via the microbiome. Obesity, which is a major risk factor for other metabolic disorders such as type 2 diabetes,...

Research in mice shows how diet alters immune system function through a gut microbe
by Harvard Medical School Credit: Pixabay/CC0 Public Domain The cliché “you are what you eat” has been used for hundreds of years to illustrate the link between diet and health. Now, an international team of researchers has found the molecular proof of this concept, demonstrating how diet ultimately affects immunity through the gut microbiome. The work,...
