Absurd! Where did you earn your MD? Is it even real? The body has a natural buffering mechanism to keep the body within an acceptable pH. If you go outside of that, you're dead, ding-dong. And regarding your scare tactics about consuming "acids" and the wastes they produce--so you're advocating everyone stop eating citrus?
Please. People, don't listen to people who rely on you being convinced for them to earn a buck.
