AI synopsis
What people are saying
The group shows strong interest and moderate engagement with the publication, citing details like stomach pH levels, species comparisons, and evolutionary implications. Tone varies from curiosity to slight skepticism, with some posts emphasizing scientific data and others questioning interpretations, illustrating a thoughtful debate about human digestion and diet evolution.
Most discussions agree that the study provides evidence supporting the idea that human stomach acidity is similar to that of scavengers, with some posts emphasizing the significance of gastric pH in human evolution and diet.
Posts show high interest, with many users referencing specific data points like stomach pH levels and comparing species, indicating curiosity about the research and its implications.
Participants reference scientific papers, mention specific figures, and debate dietary and evolutionary aspects, reflecting a moderate depth of discussion rather than superficial comments.
The discussions highlight the relevance of the study in challenging modern dietary norms and understanding human evolutionary history, suggesting a moderate to high impact in these areas.
Abstract in brief
- The study suggests that stomach acidity plays a crucial role in shaping gut microbiomes by filtering out external microbes, especially in species that eat more risky or closely related organisms.
- Comparing different animal groups, scavengers and carnivores tend to have higher stomach acidity than herbivores or those eating distantly related prey, which helps protect against pathogens.
- Variations in stomach acidity within species, such as with age or medical procedures, impact gut bacteria and pathogens, supporting the idea that gastric pH is a key factor in microbial community structure and health.]

Most liked on X and Blueskylol No. Human fasting stomach pH is not most in line with carnivores or herbivores. It's most in line with scavengers. We ate whatever we could eat, including rotten food. We have low stomach pH to avoid infection, thats all. https://t.co/H46AZhcZMk https://t.co/tO4iAepDcJ https://t.co/rWVt2V25f4 https://t.co/7Lst4b5U98

@kevinstock12 It's not scientifically sound to compare one species with three groups of animals, where even birds, mammals and reptiles may be part of the same group. Here's a better list, e.g. cats (clearly carnivores) have a pH of 3.6: https://t.co/HvY1hciDBg

@TantricTurds Wow thats an awesome study. I read a lot of these other studies and they all end up concluding "humans ate mostly plants" but I just don't believe it. This is fascinating. That is a very low PH level. Feeling racoon like. https://t.co/mE7BfqM8Wo

@HenryFailsafe @RandyBTweeden Humans have one of the strongest stomach acids on the planet, and don't require fiber for peristalsis.

The latest trend in the meat based camp is talking about stomach acidity being prof that we’re meant to be carnivore. That may be so, but apparently a dog’s stomach pH is 4.5. Just something to be aware of. Fascinating stuff. https://t.co/ICyueAdcTC https://t.co/JHc3eUe7hp

@Plant_proof @CarnivoreMD That's irrelevant: Data seem to suggest that species-specific communities in the human gut appear relatively resistant to perturbation...
