Most acid reflux is due to mechanical action of a sphincter not working correctly. This, if correct, is an edge case.
This is most likely an evolutionary flaw that can't be fixed short of genetic engineering. I also have this my experience is your opposite. Carbs cause excess acid for me and that means my leakage rate is higher. Eating more meats and veg helps a lot. As others have stated, the traditional human diet is relatively low carb, so our modern diets are things our bodies are fairly unequiped to handle (carb crashing, obesity, celiac, etc).
I'm glad you found something that works for you, but most reflux sufferers don't have a "good" vs "bad" acid problem, they have a sphincter problem.
