Is it possible that this phenomenon is specific to people with those mental illnesses? A wider general population study resulted in the inverse effect:

I only did a postgraduate degree, so I don't have the practice reading scientific studies to determine which is true. Maybe someone with more knowledge can chime in?

Research doesn't show that dietary acids affect body pH that much.

There's massive buffer systems in the body.

Yep, homeostasis

Source? There are many sources that show that pH in urine and saliva increases when people drink alkaline water.

Of course urine would, its the result of kidneys eliminating the acid brought to them by the plasma buffer system. But blood and body Ph don't change.

The body is incredibly complex so I'm not saying this is conclusive but here's a source plus a lot of explanation with numerous experiments.

Another thing: Calcium strongly associates with acid.

And there's no evidence of osteoporosis or bone leaching with high acid diets.
