energy drinks

I was looking through articles in the New York Times and I came across one on Red Bulls and how they won't be selling them anywhere any longer. I love Red Bulls, but I haven't had one in a couple years because of hearing how unhealthy they are. The article was basically saying that athletes, children and college students tend to drink them, and other energy drinks, often and there is no evidence of the drinks have positive or negative long-term effects. After testing, it was found that girls and boys have different body temperature increases, heart rate increases, etc. It was said that althletes should not drink the caffeinated drinks for energy because it actually dehydrates them, and 1/4 of the drink is sugar.

I thought it was interesting for them to say that there are no proven facts as to whether the energy drinks cause issues, yet they're permanently taking Red Bulls off the shelves. Why wouldn't they take all energy drinks out of stores? Why Red Bulls in particular? They didn't really mention why...
