Is SALT triggering your headaches?

Cutting down on salt could cut headaches by a third, according to new research.
People who reduced their salt intake to three grams a day suffered significantly fewer headaches, a study found. 
Three grams of salt is the equivalent of around half a teaspoon, or the amount found in a McDonalds Big Mac and large fries.  Experts said cutting salt could reduce headaches because it lowers blood and pulse pressure.
But even people with normal blood pressure saw a reduction in headaches when they cut their salt intake.  However, switching from a healthy diet to an unhealthy one had no effect on headaches, scientists said.
As part of the study almost 400 people were randomly assigned either a low-fat diet rich in fruits, vegetables and low-fat dairy products or a typical Western diet as a control.
Participants ate food with almost nine grams of salt a day for a set period, reflecting average salt consumption in the USA.
