In The News Young children's oral microbiota could serve as early indicator for obesity ▫️Weight gain trajectories in early childhood are related to the composition of oral bacteria of two-year-old children, suggesting that this understudied aspect of a child's microbiota - the collection of microorganisms, including beneficial bacteria, residing in the mouth - could serve as an early indicator for childhood obesity. ▫️A study describing the results appears September 19 in the journal Scientific Reports. ▫️A healthy person usually has a lot of different bacteria within their gut microbiota. This high diversity helps protect against inflammation or harmful bacteria and is important for the stability of digestion in the face of changes to diet or environment. - There's also a certain balance of these two common bacteria groups, Firmicutes and Bacteroidetes, that tends to work best under normal healthy conditions, and disruptions to that balance could lead to dysregulation in digestion. ▫️Lower diversity and higher Firmicutes to Bacteroidetes (F:B) ratio in gut microbiota are sometimes observed as a characteristic of adults and adolescents with obesity.
