Soft drinks contain the gascarbon dioxide which when consumed removes the calcium from the bones and teeth thus causing damage. Since bones form the skeleton of our body any damage caused can be fatal.As per survey conducted it revealed some scary facts:- 1.A tooth kept in a glass containing soft drink vanished within 12 hours. 2. A can of Coke can be used to remove difficult dirt stains in the toilet. 3. Daily consumption can also make one an addict and once an addict it is very difficult to overcome the same. This can be very scary only if soft drinks are consumed on a regular basis.If they are consumed rarely I dont think it would make any difference.But I feel its best to avoid especially if we have the choice of water or any natural fruit juice.
