Regular cola drinking associated with kidney disease

Dr. Rutledge, I'm a fan of Moxie (1) soda. It's a dark soda, like cola, and is flavored with gentian root. It's mostly sold in the Northeast.

 When I read about the phosphates in the soda being the possible cause of CRF, I checked out my can of Moxie to see if it also contained the same ingredient.

 What I found was "phosphoric acid" as one of the last ingredients. I wondered if the phosphoric acid contained in Moxie was the same as what you say comes in cola. With a bit of research, I discovered that the ingredient was, indeed, the same one. At the same time, I also learned about why it's used, and why it's not contained in other sodas:

"Acids are added to soft drinks for extra bite, and mouth feel. The primary acid used in colas is phosphoric acid, while the one used in citrus flavored drinks is usually citric acid." (2)

 So, you can add Moxie to your list of sodas containing phophates.

Also - I also did a search on Root Beers, and they all seem to be free of any phosphates.
