Many researchers believe that the body keeps phosphorus and calcium in balance in the bloodstream. The problem arises when the blood levels of phosphorus get too high. To stay in balance, the body pulls calcium out of bones and into the bloodstream. The result is lower levels of calcium in the bones, which could contribute to osteoporosis. Phosphorus is found in carbonated beverages, so it is believed that too many of these drinks can lead to osteoporosis.
