I used to think the episodes were a result of eating acidic foods (e. g., tomato sauce, etc. ), but found that consumption of non-fat dairy actually was the underlying cause that made my system intolerant of those foods. I can eat the other foods now with no problem.
Be sure to read labels, because skim milk and skim milk powder can be found where you least expect. I rarely get reflux now, but can trace it back to accidental ingestion of non-fat dairy every time it happens.
Hope this helps someone.
