it is not a good idea-drink water or crystal light
soda, even diet ones, may not be safe:
Carbonated beverages and urinary calcium excretion
Robert P Heaney and Karen Rafferty 1 From the Creighton University Osteoporosis Research Center, Omaha.
Background: Intake of carbonated beverages has been associated with increased fracture risk in observational studies. The usual explanation given is that one or more of the beverage constituents increase urinary calcium.
Objective: We assessed the short-term effects on urinary calcium excretion of carbonated beverages of various compositions.
Design: An incomplete random block design was used to study 20–40-y-old women who customarily consumed 680 mL carbonated beverages daily. Four carbonated beverages were tested: 2 with caffeine and 2 without. Two contained phosphoric acid as the acidulant and 2 contained citric acid. The study included one neutral control (water) and one positive control (skim or chocolate milk). Serving size was 567 mL for the carbonated beverages and water and 340 mL for the milks. Beverages were consumed with a light breakfast after an overnight fast; no other foods were ingested until urine collection was complete. pH, titratable and total acidity, sodium, creatinine, and calcium were measured in 2-h (morning) fasting and 5-h postbeverage urine specimens.
Results: Relative to water, urinary calcium rose significantly only with the milks and the 2 caffeine-containing beverages. The excess calciuria was 0.25 mmol, about the same as previously reported for caffeine alone. Phosphoric acid without caffeine produced no excess calciuria; nor did it augment the calciuria of caffeine.
Conclusions: The excess calciuria associated with consumption of carbonated beverages is confined to caffeinated beverages. Acidulant type has no acute effect. Because the caffeine effect is known to be compensated for by reduced calciuria later in the day, we conclude that the net effect of carbonated beverage constituents on calcium economy is negligible. The skeletal effects of carbonated beverage consumption are likely due primarily to milk displacement.

Diet soda may contain Aspartame which is in Nutrasweet and other artificial sweeteners. There have been studies that have associated the Aspartame with slight brain disfunction and development.

I'm a diet pepsi addict...thanks for posting something I've been wondering for a while now. I think it's fine as long as youre getting enough water and not chugging diet soda all day long.
Snapple makes those Diet Air and Diet Ice element drinks, I think they only have 5 cals/serving. Two thumbs up, they're so good you don't realize they're diet drinks. Much better than diet soda any day and no carbination.

I've heard of those studies...they were done on lab rats and a higher amount of aspartame was given to these rats at one time than a human would ever reasonably consume over a long period.

diet soda
give me a fukin break..diet soda as oppossed to full calorie cola is way better..i drank a shit load of it it for 16 months, lost 110 lbs, no I look fukin awesome, am a fitness instructor, and I totally rock.. the majority of you guys need to lighten up and not be so damn cultish...........I promise you will not die or balloon up if you eat 3....instead of 2......chicken breast a day.God,,lighten the fuk up

um...ok...most of us eat more than 2 or 3 chicken breasts a day...the more protein the better. I thought we were on the subject of diet soda?

The rat tests were done in the 70's using saccharin, not aspartame. And yes, the rats were given massive doses and many got cancer. That's why to this day, all diet sodas containing aspirin say something like, "saccharin has caused cancer in laboratory animals" right on the can.
I don't think saccharine is carcinogenic (see above):
and what do you think of cyclamate ?
In 1958, saccharin was added to the GRAS (Generally Recognized as Safe) list, another paradox.
In 1972, the results of a long-term study showed that rats fed saccharin had developed bladder tumors. Subsequently, the Food and Drug Administration (FDA) removed saccharin from GRAS status and issued a regulation limiting the use of saccharin in foods. Then in 1974, a National Academy of Science review found that, "Saccharin itself could not be identified as the cause of the tumors because of possible impurities as well as problems with experimental design and procedures" (Kennedy 131).
Therefore, the FDA decided not to ban saccharin
