Just a couple days of avoiding bad foods don’t help. This is something you have to commit several weeks to, to see an improvement. You also need to do this in conjunction with the baking soda and Gaviscon advance or something to neutralize and keep the pepsin from coming up while you are healing. I talked about that in my first two comments. At first if you have this, all foods will irritate you, even safe ones, until you heal. The only fruits you can eat during the healing phase are melons- so it’s a pretty strict diet. It’s only for 30 days though until you can start adding things back in. The thing with LpR is that the pepsin event only needs to happen sporadically to cause damage, unlike GERD. It could stem from vagus nerve damage or a functional issue, not diet, so it seems random but it isn’t- it might not be the food causing it if it’s one of those problems, and it may not happen every time you eat if that’s the case. It’s not just fried foods- some of those would actually be fine- it’s things like onions garlic caffeine- these cause the esophageal sphincter to relax and let the pepsin up. The acidic foods like tomato sauce vinegar citrus are normally healthy but they are irritating tissue that’s already inflamed which is why they are avoided during healing.
