Acid Watcher Diet. There are two ENTs that I know of who have written books on using a low acid diet to manage GERD without drugs. One is Dr. Jonathan Aviv; there is a FB page that offers a ton of recipes based on his book.

Then there is Dr. Jamie Koufman, who has a slightly different take on what you can eat on a low acid diet. She has a website https://jamiekoufman.com.
