I had a talk with a naturopath today. He said they have found that 20% of heartburn cases have too much acid, and the other 80% have insufficient acid. He said how this contributes to poor motility - the food just hanging out in the gut - and how that causes heartburn.
He also said that many people, in their effort to cut down on sodium, have eliminated an essential contributor to the balance of the digestive system. He said that they actually recommend that some people take some sea salt dissolved in a glass of water during the day. This hit home for me - I have very good b.p., but almost never use salt. ...Another contribution to reflux?
