Choline in certain foods can get converted by bacteria into a substance called trimethylamine (TMA) that is associated with heart disease when it gets absorbed into your body and converted to TMAO. However, TMA conversion doesn’t happen in individuals without these types of bacteria in their microbiome.
We can see the TMA production pathways and many of the gammaproteobacteria that do this conversion.
What foods contain choline? Liver, salmon, chickpeas, split peas, eggs, navy beans, peanuts, and many others.
Before you decide to go full-on pescatarian or paleo, you may want to check if your microbiome is producing TMA with that salmon or steak.
