I drink Diet Coke every day, but I have good density according to my scan. Of course, I also have a high intake of high calcium. Wouldn't want me to withdraw from my Diet Coke, no way. no how!! I was also under the understanding that it was the PO4 also. I am also leery of so many reports that tell me what is bad for me. There seems to be something new everyday. I think we ought to go to the ice cream sundaes as "good for you" like in the Woody Allen movie "Sleeper".
