Researchers of a study aimed to assess the link between the intake of dietary fiber and the prevalence of severe headaches or migraine through a cross-sectional study of 12,710 subjects. Data was assembled from NHANES 1999-2004. The overall incidence of severe headache or migraine was 19.9%. Researchers identified a considerable inverse link between dietary fiber intake and severe headache or migraine, following the adjustment for correlation covariates. The researchers also found from the study that there was a decrease in the prevalence of severe headache or migraine by 11% for every 10 g/day growth in intake of dietary fiber. It was noted that more research is needed to confirm the study’s association of increased fiber intake and the protection of severe migraine or headache.
