I checked the Acid Watcher book out of the library. Haven’t read it all in detail but in looking at the diet info, I can see that for me (and anyone else with IBS who follows the Low FODMAP diet) this would be the “dueling diets” scenario. Some foods that the author recommends (eg avocados, watermelon and honey) are triggers for IBS. And vice versa—some of the foods allowed on the IBS diet are not on the acid watcher regimen. Most of the obvious things like tomatoes, caffeine and carbonated beverages are well known reflux triggers and anyone with GERD would already know to avoid them. The book presents an interesting approach but I won’t be following the diet.
