diet coke

It's not anymore dangerous than any other softdrink, or for that matter, water. Please check with www dot snopes dot com. They debunk alot of urban legends and myths. They have a whole section dedicated to coca-cola. There's alot of misinformation concerning the minute amounts of acid, carbonation, sweetners, etc found in coke. Most to be concerned about is caffeine, but if you drink coffee without problems, diet coke is safe as it contains less caffeine that a cup of coffee.
