Journal ArticleDOI
The role of the gut microbiota in nutrition and health
TL;DR: The complex interplay between the gut microbiota, diet and health is considered and better definition of those dominant commensal bacteria, community profiles and system characteristics that produce stable gut communities beneficial to health is important.
Journal ArticleDOI
Microbial degradation of complex carbohydrates in the gut
TL;DR: The impact of dietary carbohydrates, including prebiotics, on human health requires understanding of the complex relationship between diet composition, the gut microbiota and metabolic outputs.
Journal ArticleDOI
Dominant and diet-responsive groups of bacteria within the human colonic microbiota.
Alan W. Walker,Jennifer Ince,Sylvia H. Duncan,Lucy M. I. Webster,Grietje Holtrop,Xiaolei Ze,David Stanley Brown,Mark D. Stares,Paul Scott,Aurore Bergerat,Petra Louis,Freda M McIntosh,Alexandra M. Johnstone,Gerald E. Lobley,Julian Parkhill,Harry J. Flint +15 more
TL;DR: Time courses obtained by targeted qPCR revealed that ‘blooms’ in specific bacterial groups occurred rapidly after a dietary change, and these were rapidly reversed by the subsequent diet.
Journal ArticleDOI
The microbiology of butyrate formation in the human colon.
TL;DR: A better understanding of the microbial ecology of colonic butyrate-producing bacteria will help to explain the influence of diet uponbutyrate supply, and to suggest new approaches for optimising microbial activity in the large intestine.
Journal ArticleDOI
Human colonic microbiota associated with diet, obesity and weight loss.
Sylvia H. Duncan,Gerald E. Lobley,Grietje Holtrop,Jennifer Ince,Alexandra M. Johnstone,Petra Louis,Harry J. Flint +6 more
TL;DR: Diets designed to achieve weight loss in obese subjects can significantly alter the species composition of the gut microbiota, but there is no evidence that the proportions of Bacteroidetes and Firmicutes among fecal bacteria have a function in human obesity.
