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.
New research sheds light on the effects of inflammatory bowel disease risk alleles on gut bacterial taxa
8 Apr 2019by GMFH Editing Team
Scientists struggle with elucidating how host and gut microbiome interact for shaping the genetic susceptibility of IBD. In 633 IBD patients, Harry Sokol and colleagues have found associations between genetic variants associated with a higher risk of IBD and the depletion of certain gut bacterial taxa.
An update of the scientific evidence behind the microbiota-specific effects of common dietary patterns
21 Mar 2019by Andreu Prados
In our daily life nutrients aren’t consumed in isolation, so scientists are interested in understanding how dietary patterns modulate the intestinal microbiota. Two recent reviews update what we know about the impact of common dietary patterns on gut microbiota.
Fiber is not everything: dietary fat type shown to be relevant for gut microbes
14 Mar 2019by Andreu Prados
Other substrates beyond non-digestible carbohydrates can be used as a fuel for the gut microbiota. Scientists have turned to the role played by dietary fats in human gut microbiome composition.
Fermentable fibers affect the structure and function of gut microbiota, with potato starch leading to the greatest increase in short-chain fatty acids
4 Mar 2019by Andreu Prados
Resistant starch is a highly fermentable fiber, although it’s considered to be an insoluble fiber. What is more interesting is the fact that the food source of resistant starch matters, as scientists show not all foods that are high in resistant starch drive identical changes in gut microbiota’s functional diversity.
Scientists succeed in deciphering microbiome contributions to drug metabolism
28 Feb 2019by Andreu Prados
Little is known about the quantitative contribution of the host and the gut microbiome to drug metabolism. Using an experimental and computational methodology, scientists have provided some clues about how the gut microbiome influences our ability to metabolize antiviral drugs and benzodiazepines.
A new review calls for the gut microbiome to be considered as part of standard nutritional rehabilitation for anorexia nervosa
14 Feb 2019by GMFH Editing Team
The gut microbiome has been largely underexplored in the development of anorexia nervosa. Scientists call for standard nutritional rehabilitation in these patients to be reconciled with gut microbiota-targeted nutritional modulation.
The gut microbiome’s influence on non-communicable diseases and behaviour: main findings of MyNewGut project
11 Feb 2019by Andreu Prados
The European Union-funded microbiome project MyNewGut has come to an end. Discover here the project’s take-home messages regarding how we can target the gut microbiome for fighting obesity, metabolic syndrome and emotional disorders.
Gut microbiome development continues between 6 and 9 years of age, with pre-school diet and breastfeeding acting as major driving forces
28 Jan 2019by GMFH Editing Team
During the first 2 to 3 years of life, gut microbiota modulation appears to play a critical role in later health outcomes. New observational work reveals that breastfeeding duration and pre-school diet are major modulators of the gut microbiota of children aged between 6 and 9 years.
Intestinal bacteria may protect against cow’s milk allergy by regulating host immunity
24 Jan 2019by Andreu Prados
The way intestinal immune cells distinguish innocuous dietary antigens and gut bacteria from pathogenic microbes and mount an appropriate response to each is unknown. New research unravels how intestinal bacteria may protect against cow’s milk allergy by regulating host immunity in mice.
