How much water does it take to neutralize a cup of coffee's acid?

And that sweetener is awful, worse than corn syrup, ive lost 35 pounds going off corn syrup. It causes you to store fat, it does. But diet drinks are worse than energy drinks. They actually cause people to eat more and gain weight, plus have other serious issues.

Cant spend a buck for a 16 oz coke when a 2 liter is.... Back in the day it was plenty, 16 oz. before we super-sized as a nation. We used to get 8 oz cokes at mc'D's in the sixties. the old man on Pawn shop was talking about how old cokes and Pepsi were much different now, and how he hates that they now are made with corn syrup, even more carbonation. People in Okinawa are naturally exposed to coral calcium and it is sold and many normalize ph that way.
