I think that this discussion is bordering on debate and maybe should move there. As a follow up to this, you can make anything including oxygen, water, you name it look like a deadly element or compound through the use of a chart like this. Ingestion of too much water or oxygen will kill you.
Our bodies are literally chemical factories... if the body needs acid to digest food it will make it, if it needs to neutralize that acid after it is finished doing its job, it will use available alkaline minerals to do that.
Using any tool to balance your alkaline\acid means you have to take responsibility for yourself and the use of that\those tools in knowing what you need and how much to stay in balance. We are all so different, including our diets that our doses of alkaline minerals could vary widely. That is why it has been repeated over and over again to test your alkaline/acid balance with pH strips.
