https://worldpopulationreview.com/country-rankings/stomach-c... suggests Mongolian, Japanese and Korean diets are the worst. What do their diets have in common? High traditional intake of distilled alcohol, pickled foods, and meat. IIRC pickled foods are alkaline and weaken the stomach's acidic environ, exposing stomach lining to compounding damage from alcohol, chilli, etc.
