Gut microbiome composition, heart health in 3 common diets
Distinct gut microbiome patterns could be linked to cardiometabolic health in individuals following certain diets.
In a study published in Nature Microbiology, researchers analyzed the gut microbiome samples of individuals following a vegan, vegetarian or omnivore diet.
The researchers found that the consumption of red meat greatly influenced the gut microbiomes of individuals consuming the omnivore diet — leading to the proliferation of bacteria associated with poorer cardiometabolic health. Bacteria such as Ruminococcus torques, Bilophila wadsworthia and Alistipes putredinis were prevalent among those following the omnivore diet.
Conversely, improved cardiometabolic health among those following vegan diets and enriched cardiometabolic health in those following the omnivore diet were correlated with the consumption of plant-based foods. The bacteria Lachnospiraceae, Butyricicoccus species and Roseburia hominis, which are known to produce butyrate, as well as fruit- and vegetable-derived bacteria like Enterobacter hormaechei and Klebsiella pneumoniae were more prevalent in the individuals who followed the vegan diet. Those who followed the vegetarian and omnivore diets exhibited Streptococcus thermophilus, a bacteria used as a dairy starter.
The researchers emphasized that their findings demonstrated how individuals can influence their gut microbiome composition and overall health through dietary choices.
