Diet greatly influences gut microbiota composition, and evidence shows how the way gut microbiota metabolizes our food may be more relevant than the actual food we eat.
The copy number variation of the gene that encodes salivary amylase may be related to human microbiome diversity and function
14 May 2019by GMFH Editing Team
Twin studies have revealed a link between host genes and the gut microbiome. New findings reveal that our gut microbiome may also respond to copy-number variations in host genes, for instance those encoding the salivary amylase enzyme.
Scientists identified two bacteria from gut microbiota linked to mental health
8 May 2019by Cristina Sáez
Researchers at KU Leuven in Belgium have found most human gut bacteria produce neurotransmitters, which are chemicals (e.g. dopamine and serotonin) that let neurons communicate with each other.
Could increasing delivery of propionate to the human colon be a potential way of improving glucose homeostasis in overweight or obese individuals?
6 May 2019by Andreu Prados
Colonic propionate has been suggested as a potential target to improve obesity-related metabolic disorders. Based on new research, colonic propionate delivery could be a novel solution to improve metabolism and inflammation in overweight or obese subjects.
Bifidobacterium longum 1714 may modulate brain function in response to social stress in healthy adults
2 May 2019by Paul Enck
The benefits of probiotics in human health is a hot area of research. Using neuroimaging methods, Paul Enck and colleagues have shown in a new randomized, double-blinded, placebo-controlled trial that the probiotic Bifidobacterium longum 1714 may reduce stress response in healthy volunteers.
A new cohort study reveals variations in milk and infant fecal microbiota within and between populations
30 Apr 2019by GMFH Editing Team
Commensal bacteria in mother’s breast milk may shape the infant’s fecal microbiota. A new cohort study has found associations between both samples, with mother’s milk and infant fecal microbiome composition being more similar within than across cohorts from different geographic locations.
Genetic variations in gut microbiota are stable within individuals and shape host disease risk factors
25 Apr 2019by GMFH Editing Team
To what extent gut microbial genetic variations shape phenotypic differences of the host remains to be seen. Structural variations in 75% of bacteria have been replicated in two Israeli and Dutch cohorts, regardless genetics, lifestyle and dietary background.
How to take care of your digestive health: regular fermented milk consumption can improve mild digestive symptoms
25 Apr 2019by Allison Clark
A recent study by Philippe Marteau has analyzed and evaluated the speed at which abdominal discomfort improves after a fermented milk product (FMP) is consumed.
Two new studies reveal universal gut microbiome signatures in colorectal cancer
22 Apr 2019by Andreu Prados
Genes aren’t the only culprit behind the current dramatic rise in colorectal cancer prevalence. Two new articles in Nature Medicine reveal specific microbial signatures for colorectal cancer, with potential use as candidates for developing non-invasive colorectal cancer screening.
Could our gut microbiota mediate the impact of bariatric surgery on severe obesity? A new cross-sectional study has found that interactions between the gut microbiota and bile acids metabolism may partially mediate the success of bariatric surgery in the medium term.
