DEAR DOCTOR K: I know I should drink plenty of water every day, but sometimes I get tired of drinking plain water. So I reach for club soda, seltzer water or sparkling mineral water. But I've heard that carbonated drinks could be bad for my bones. Is this true?
DEAR READER: Several of my patients have asked the same question. Sometimes they are not asking about carbonated water, but carbonated beverages that contain caffeine (like colas) and sugar or sweetener. I'll tell you what I tell them.
