Your brain needs fuel to run, and the fuel it uses is glucose. But unlike other cells, your brain can't store glucose. It depends on the second to second supply from the bloodstream - a bloodstream that is affected by pH which controls the efficiency of insulin which allows sugar to enter into cells which in turn controls blood sugar levels. There are hundreds if not thousands of enzyme processes which take place in our body. Enzyme function and thus life itself begins to suffer.
Minerals have different pH levels at which they can be assimilated into the body.
For example, as more acid accumulates in our body, it gets stored and pushed further, and ultimately it gets pushed into the cell. When it gets pushed into the cell, the first thing it does is displace potassium and then magnesium and then sodium. Those are three critical minerals in our body. The potassium and magnesium will leave the body, but as a preservation mechanism the sodium will be retained. Remember, the body knows it must place an alkaline molecule in the blood to escort out this increasing acid that is being stored in the tissues and cells.
