You didn't understand a word I said did you? That's sad some people will just never improve.
Think of it this way. What did humans eat before the stone age? Fruit that's it. We don't have the digestive system of a meat eater thier is completely different.
We don't have the digestive system of a herbivore they have several growth chambers full of probiotics to break down the plant matter they eat.
We have one stumic with weak acid and little bit if intestine. We are not designed to eat meat,dairy,grains of any kind.
Simple as that.
Your study is bullshit. Of course you can make your entire body alkaline the human body won allow that to happen it will leach mineral from bones and tissue so it does not happen.
