A new study has revealed that the major cause of headaches may be diets containing high salt content.
The study found that people who ate foods high in sodium (8 grams a day) had nearly one-third more headaches than people who ate foods low in sodium (about 4 grams a day). The difference persisted regardless of whether the volunteers ate a standard North American diet or one designed to lower blood pressure.
AdvertisementStudy co-author Lawrence Appel, M.D., M.P.H., director of the Welch Center for Prevention, Epidemiology and Clinical Research at Johns Hopkins revealed that many Americans consume much more sodium than any of the study participants did. People may avoid some headaches simply by reducing salt consumption.
The study was published in the journal BMJ Open.
