Anonymous (and Honest Abe) asked: "Can you comment on the current fad of drinking alkaline water. People are spending thousands of dollars on machines that use electrolysis to make alkaline water. I can't see how this is real, nor can I understand how any alkaline water could be useful in the acidic environment of the stomach. "
Well, no, not really, not much. The mouth is alkaline and the stomach is acidic. The advantage of this is that, having an alkaline mouth, your teeth don't dissolve.
Beyond that, I can see no advantage of alkaline water.
