Drinking coffee every day can reduce the risk of developing migraines, according to a recent study. The study, published in the European Journal of Clinical Nutrition, used Mendelian randomization (MNR) techniques to establish a cause-and-effect relationship between coffee consumption and a reduced risk of developing migraines.
Coffee is one of the most popular beverages in the world, and many studies have been conducted to identify the association of the beverage with human health. Scientists around the world have worked to identify the associations in previous studies, but these studies have been mostly observational. This has made it challenging for researchers to remove the effects of bias that could have affected the results.
However, recent studies have used magnetic resonance imaging (MRI) to assess the potential link between coffee consumption and migraines and neurological diseases.
The method uses genetic data associated with risk factors, but not the diseases themselves, to identify instrumental variables (IVs). In this study, the researchers identified single-nucleotide polymorphisms (SNPs) known to influence coffee consumption as IVs.
The researchers used a genome-wide association study (GWAS) from the UK Biobank, based on more than 400,000 people of European ancestry. Using the data, the researchers identified 40 SNPs – ssingle nucleotide polymorphism – each independent, so their association with coffee consumption was of little significance.

According to the analysis, coffee consumption reduces the risk of developing migraines and migraines with aura – sensory symptoms that often occur before a migraine.
However, no association has been identified between coffee consumption and migraine without aura. Furthermore, no association has been found between coffee consumption and other neurological diseases

The study results indicate a forceful association between coffee drinking and a reduced risk of migraine, with coffee consumption likely being a trigger or preventive strategy for migraines.
