Gut feelings
Progress continues to be made in understanding gut microflora and metabolic pathways. A study with Pennsylvania's Old Order Amish population indicated that specific gut bacterial groups may be associated with metabolic syndrome traits.
The Amish were identified as an ideal subject population because close genetic relationships, similar lifestyles, and low prescription drug usage.
The data, published in PLoS ONE, indicated that some specific species, but not full gut communities, were associated either positively or negatively with metabolic syndrome traits.
"We can't infer cause and effect, but it's an important step forward that we're starting to identify bacteria that are correlated with clinical parameters, which suggests that the gut microbiota could one day be targeted with medication, diet or lifestyle changes," said lead researcher Claire Fraser.
The study adds to emerging body of science supporting the effects of gut microflora on metabolic factors and obesity.
