A friend told me that drinking carbonated beverages (including carbonated water) is detrimental to healthy bones. Is this true?

People have asked me this question before, and I've checked the medical literature. But I haven't found any research suggesting that carbonated beverages are harmful for bones. Nor can I think of any reason that they would present a problem - so long as you aren't replacing healthy drinks, like milk or fruit juice, with the empty calories of sugary sodas.
