A new study has revealed that the major cause of headaches may be diets containing high salt content.

Study 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.
