I get really bad GERD from coffee and black tea, a bit less from green tea. I don't get GERD from Mate tea or energy drinks. So I think it's not the caffeine.

I get really bad GERD from coffee and black tea, a bit less from green tea. I don't get GERD from Mate tea or energy drinks. So I think it's not the caffeine. Since they both contain high amounts of caffeine, even higher than black tea. I've noticed that if I eat more fiber I can somewhat mitigate this. But it needs to be consistent. Not just a little extra fiber before coffee. BTW a high-fiber diet can be a natural ozempic by raising GLP-1 levels.
