This guy sounds like a total quack. He runs an MLM company selling Okinawan calcium. He credits Okinawan longevity and total absence of cancer (wrong- there's plenty of cancer there) to their magical coral calcium. He's a chemist, but obviously knows nothing about how the human body works. If he did, he'd know that you *can't* change your blood pH. If you did, you'd die. Your body keeps it within a very narrow range. Food and suppliments can't change it, unless you massively overdosed. He throws around the word "acidosis" totally out of context: if you have acidosis, you're having a life-threatening metabolic emergency.

If it sounds too good to be true ...
