A new study has found that germs found in the mouth and gut may be associated with migraines. Specifically, migraine sufferers had higher levels of nitrate-reducing microbes, compared to those who do not experience migraines. The study analyzed 170 samples from the mouth and nearly 2,000 fecal samples.
Lead author of the study Antonio Gonzalez said, “There is this idea out there that certain foods trigger migraines — chocolate, wine, and especially foods containing nitrates. We thought that perhaps there was a connection between someone’s microbiome and what they were eating.”
The study did not establish causality, so additional research is required in order to better learn about this association.
