Is diet coke bad for your health?

All sodas: Whether diet or not are not the healthiest to drink. Sugar is not the only culprit in soft drinks. Water is the healthiest bar none.

For teeth: Soda pop contains corrosive acids such as citric, malic, tartaric carbonic or phosphoric which, can remove calcium from tooth enamel. Without protection from the dental enamel, the tissue underneath is susceptible to cavities, root canals & even extractions. Sugar is an additional cavity causing issue, so consider rinsing your mouth after drinking soda, both diet & soda containing sugar.

Not as bad as regula: It's definitely not good for you, but far better than regular coke with sugar. If you simply must have a soda, go with the diet. It is best to avoid soda altogether because it is very acidic and dissolves tooth enamel. The ingredients in diet and regular soda are not good for your overall health either. I'm going to say one or two diet sodas a day probably won't hurt you.
