Diet Coke & Infertility?

Just thought this was interesting...
My mom called me today and said she heard on the 107.1 morning show that there are new studies out there that are linking diet coke to infertility. I was VERY dissappointed when I heard that. I love diet coke! I have at least 2 cans a day. I haven't read any studies on it, but I am guessing that its the caffiene they are worrying about. Its just interesting all of the different things that can play into how our body works. There is so much more we are learning everyday about how products used for many years are actually harmful to us and affect the way we work. Its amazing! I guess I will have to try and substitute my diet coke for something else. This will be my greatest challenge yet!
