May I submit to you that, for example, the lemon and the lime you are taking may not be as alkalizing as you thought. Ha Ha!
What I learned at another forum is that the quality of produces may make a big difference in the way they produce alkaline ashes. This is not something you will learn from the good Doctor.
Don't take me wrong, I think Dr Young has done a lot in introducing to the mass pH balance concepts. I have three or four of his books. But you will find that there is more. And that there are cheaper ways too.
