The question of stomach pH frequently comes up during the discussion of how appropriate a meat or carnivore diet is for humans. One way to discuss this in a meaningful way is compare human digestion to that of other animals with know dietary habits. I will list resources below for people to explore on their own. I am convince humans are fine tuned to digest meat (raw or cooked). In short, the lower the pH level the more powerful the acid, the more powerful the acid the better suited for digesting meat and destroying pathogens. Healthy humans tend to have a stomach acid pH from about 1-3 depending on the sources you read.
