YVONNE W: I drink flavored carbonated water. The water I drink tastes almost as sweet as soda. The flavors are (rasberry, key lime, apple peach, blackberry, cherry, white grape etc.).

I never use flavored water when I'm working out, however, during a spinning class I noticed one of my classmates with a bottle of this water on her bike. I began to wonder is this water good or bad for me. I read the ingredients label, yet I still don't know if I'm causing major damage in my body.

I'd like to know what the girlfriends think.

THERESA: I love unsweetened carbonated water. Seltzer water with lemon. I don't drink it while I'm working out, but I guzzle it afterwards. While I'm working out, I just like plain old icy cold water. I try to avoid artificial sweeteners, and the new flavored waters have those, but you know, Yvonne, I doubt they're putting you at risk for major damage. I also don't like sports drinks like Gatorade or Powerade, unless I'm in the middle of a running race and need a gulp for a quick energy boost.

KIMBERLY: Well, Nancy Clark, America's leading sports nutritionist, in her book, "Sports Nutrition Guidebook," lists seltzer water on the top of the list as an alternative to water to replace sweat loss.
