Super Interesting!  So maybe increase in acid reflux due to eating what is regarded by the body as  “poison”? The body is struggling to establish an appropriate microbiome?

The evolutionary link between diet and stomach acidity

An analysis of data on stomach acidity and diet in birds and mammals suggests that high levels of stomach acidity developed not to help animals break down food, but to defend animals against food poisoning. The work raises interesting questions about the evolution of stomach acidity in humans, and how modern life may be affecting both our stomach acidity and the microbial communities that live in our guts.                                

“We started this project because we wanted to better understand the relationship between stomach acidity, diet and the microbes that live in the guts of birds and mammals,” says DeAnna Beasley, a postdoctoral researcher at North Carolina State University and corresponding author of a paper on the work. “Our idea was that this could offer some context for looking at the role of the human stomach in influencing gut microbes, and what that may mean for human health.”

More information: “The Evolution of Stomach Acidity and Its Relevance to the Human Microbiome,” will be published July 29 in the journal PLOS ONE.
