Bacteroidetes Just over half (55 per cent) of my gut bacteria were bacteroidetes. This is a good thing, according to uBiome, because having a microbiome tilted in favour of Bacteroidetes is associated with a lean body type and with less inflammation in the gut. This group of bacteria also play an important role in teaching your immune system how to behave (they help control how violent your immune response is) and in breaking down the undigested fibre from vegetables that make their way into your colon. When they do this they produce a number of valuable substances, including butyrate.
