Should you be eating acid or alkaline foods? Let's see if I can make sense of this. We are oxygen breathing, carbon-based, mildly alkaline life forms. The pH of plasma is 7.35-7.45 and the pH inside our cells is 7.1. If they change much from these levels you will end up in hospital. The body has a number of systems to control the pH in your body (eg lungs and kidneys).
Que? What this thing pH?
