Help for migraine sufferers from bacteria

People suffering from migraines tend to have particular profile of bacteria linked to nitrate processing.

I am keen not to overstate the potential of any individual scientific study. However this story highlights exciting news about a potential relationship between bacteria and migraines. In 2016 The Guardian featured a study that appeared to demonstrate a link  between the efficient break down of nitrates in humans and the occurrence of migraines. As I understand the research,  migraineurs (people that suffer from migraine) tend to have more nitrate reductase genes in both the mouth and in stool samples, than the wider population.

Nitrate reductase genes are responsible for processing nitrates in food and drinks, point being the greater their abundance the more efficient the nitrate processing. So getting more nitrates from food (compared to non migraineurs) may be linked to triggers for migraines. Obviously further research will be needed but the link between nitrates and headaches is not new. What this study is demonstrating is that the key might rest with the microorganisms in the mouth and gut.

Many migraine sufferers are aware of a relationship between certain foods and increased risks of attacks, through chocolate and wine for example. It is also known that certain drugs high in nitrates can provoke severe headaches. When broken down, nitrates lead to increased blood circulation in the cardio vascular system, this increase may be a key factor in migraines. The complexity of the human microbiome, particularly the gut-brain axis, makes demonstrating causality between food and health challenging. However this seems like a promising area of research. Controlling  the intake of foods high in nitrates might be a short term solution. But given that fruit and vegetables are rich sources of nitrates, cutting down on them could present a range of risks and benefits.

As a researcher working with the contemplative sciences, the key role that food has in health and wellbeing became evident to me. From there it was a small step to realize that fermentation and gut bacteria play an essential part in our lives. Do yourself and your loved ones a favour, check out the evidence linking gut bacteria and health now!
