My mother drank Coke since she was a teen. She had osteoporosis and osteoarthritis at a young age (40s). A physician I worked for explained to me why my mother probably developed issues so young.
Carbonated drinks contain phosphorus. Your body needs to balance calcium and phosphorus so if you consume a lot of soda, your body will release calcium from your teeth and bones until the phosphorus and calcium are in balance.
I still try to force myself to drink it though.
