Nitrate migraines

A new study suggests that migraine sufferers may be prone to symptoms because they have nitrate-reducing bacteria in their mouths and eat foods or take medicines that contain nitrates. Processed meats (including bacon, ham, and pork sausages) often have added nitrate as a preservative to prevent botulism, while some green leafy vegetables and some medications also contain nitrates. Chocolate and wine are also thought to be triggers for migraine. Researchers at University of California San Diego School of Medicine, USA, suggest that a person's oral microbiome might be the key to understanding why some people suffer this often-debilitating condition and others eating the same foods do not.
