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.
Many of the 38 million American migraine sufferers have noticed a link between consuming nitrates and getting migraines. Nitrates are commonly found in processed meats and leafy greens, as well as in certain medications.
