Gut microbiota, gut microbiome, or gut flora are the microorganisms, including bacteria, archaea, fungi, and viruses, that live in the digestive tracts of animals. [ 1 ] [ 2 ] The gastrointestinal metagenome is the aggregate of all the genomes of the gut microbiota .
Certain gut bacteria may increase the risk that a person will binge eat and become obese, a new study suggests. In a series of experiments, mice and humans with a propensity for binge eating had ...
Microbiota-accessible carbohydrates (MACs) are carbohydrates that are resistant to digestion by a host's metabolism, and are made available for gut microbes, as prebiotics, to ferment or metabolize into beneficial compounds, such as short chain fatty acids. [1]
Fruits, vegetables, whole grains, seeds, nuts and legumes are rich in soluble fiber and resistant starches, which our gut bacteria metabolize to create a short-chain fatty acid called butyrate.
The bacteria and fungi live together in the gut and there is most likely a competition for nutrient sources present. [102] [103] Seelbinder et al. found that commensal bacteria in the gut regulate the growth and pathogenicity of Candida albicans by their metabolites, particularly by propionate, acetic acid and 5-dodecenoate. [101]
"That's something no human being experienced 200 years ago," Ogino said. Lights allow us to work and socialize at all hours, impacting how our body clocks regulate hormones and metabolism.
Graphic depicting the human skin microbiota, with relative prevalences of various classes of bacteria. The human microbiome is the aggregate of all microbiota that reside on or within human tissues and biofluids along with the corresponding anatomical sites in which they reside, [1] [2] including the gastrointestinal tract, skin, mammary glands, seminal fluid, uterus, ovarian follicles, lung ...
The microbiota comprises all living members forming the microbiome. Most microbiome researchers agree bacteria, archaea, fungi, algae, and small protists should be considered as members of the microbiome. [64] [1] The integration of phages, viruses, plasmids, and mobile genetic elements is a more controversial issue in the definition of the ...
