As for the reason why carbonated drinks affect health, Professor Grace Weshke initially thinks that it is caused by phosphoric acid contained in carbonated drinks. It has also been suggested that the harm of carbonated drinks lies in that it largely replaces the milk intake in the daily diet, thus affecting the supplement of calcium to the human body. These claims need further research to confirm. But what is certain is that drinking carbonated drinks often is not conducive to human bone health.
