My immediate thought was "well, what do these bacteria feed on?".

A quick Google search reveals these bacteria produce the imidazole propionate from histidine. Unfortunately, histidine is an essential amino acid (necessary for life and our bodies can't produce it so we need it in our diet).

The bacteria in your microbiome aren't a fixed quantity. Changing diet will change the microbiome over time.

The researchers found that healthier diets and lifestyle were associated with lower levels of imidazole propionate. Trying to starve the bacteria of precursors isn't practical.
