Do soft drinks cause loss of bone mass in kids?

Some ok, some not... I agree with not drinking soft-drinks with sugar, a major issue in childhood obesity. While drinks like 7-up, sprite, & gingerale, provide no bone loss, it is well shown that drinking beverages with more than carbonated water, which are soft drinks containg phosphoric acid (colas, dr. Peppers) do cause a net loss of calcium in urine. At best, they should be occasional.
No. They do not take away bone material but they do not strengthen bones or muscles either. Soft drinks are an over load of sugar and are more damaging to your teeth. They will create lethargy in kids as well. Keep them active and get them off the couch and reduce their sugar intake.
