While enjoying a cola or two every day might seem harmless enough, recent research suggests that those tasty drinks could be compromising your bone health.
The third possible explanation focuses on one of the ingredients found in colas: phosphoric acid. Phosphoric acid can cause an imbalance in the body as the body seeks to neutralize the acid with calcium. If there isn't enough calcium in the diet, the body will take calcium from the bones.
Causes phosphoric acid imbalance
"Phosphate is in milk, but milk also contains calcium and vitamin D. In soft drinks, there is just phosphoric acid and no calcium. Extra overzealous drinking may lead to a phosphoric acid imbalance, and if there's not enough calcium, the body goes to the bones to restore the balance," explained Dr Primal Kaur, director of the Osteoporosis Centre at Temple University Health Sciences Centre in Philadelphia.

1 or 2 glasses a week OK
"Moderation is really important. If you really like soft drinks, you don't need to take them out of your diet completely, but limit yourself to one or two glasses" a week, Kaur said.
