The National Heartburn Alliance (NHBA), an organisation of healthcare professionals dedicated to providing heartburn education, has developed the "Stop & Select Guide", a colour-coded food guide designed to help prevent heartburn before it starts. A recent survey by the organisation revealed that 92% of the 25 million Americans who suffer from heartburn every day, believe that food is the primary cause of their digestive discomfort. This led the NHBA to compile information for sufferers that will enable them to change their diets and steer clear of potentially troublesome foods and beverages.
