Lots of protein, lots of fat, lots of carbs of different kinds (starches, sugars). The occurrence of reflux, or at least some pre stages of that, like unpleasant feeling and smelling gas coming up the throat, seems to be most likely if you ate a generous meal which contained lots of everything. Since this is based on experience (confirmed by some people I know, but maybe it's not universal), I can't give exact definitions of those things.īut you might be able to make sense of symptoms and connect some dots if you experiment yourself.

It is when some certain different kinds of foods, or even foods in different stages of pre-digestion, meet and mix in the stomach, and potentially also if you add fluid at certain stages of pre-digestion.

I would say that any "simple" food alone is not very likely to cause acid reflux, unless you eat a lot of it and then drink some fluid. Perhaps it's over the scope of the specific question - but if you're interested to get rid of reflux no matter whether it comes from bread or something else, here you go: Okay, disclaimer, what follows now is solely based on my personal experience (and what some friends told). I am not sure whether those anti-digestives already impact the pre-digestion in the stomach, though. While whole grain bread is said to have some healthy effects (lowering chance of diabetes II compared to white flour bread), it also contains anti-digestive substances from the grains - unless it has lots of sour dough which fermented that.
