(65,010 posts)It's mostly a cola issue because colas contain varying amounts of phosphoric acid, which adds tartness.
The phosphate anion can interfere with calcium absorption.
The carbonation is just CO2 gas, and that's weaker anion than hydroxyapatite and identical to the carbonate, which are the 2 principal inorganic substituents of bone.
For instance, seltzer or tonic water or most lemon-lime sodas wouldn't be an issue as they have no significant phosphorus content.
There's no chemistry that supports the carbonation as an issue, but the phosphoric interference is real. That said, it's not an issue with moderate consumption. But, people (like my sister in the past) going through 8-12 cans of pop a day is excessive. Ruined her teeth, too!
I don't drink pop because I'm not a sweet beverage guy, and to me, they're all too sweet.
But, if you like an occasional root beer or ginger ale, or Sprite, go ahead and enjoy. It won't hurt you. But, if your concerned about bone density loss avoid colas.
