When i was in school , i was once told by my teacher that carbonated drinks slowly dissolve the bone tissue in our bodies. his thought has been with me from then on, i wonder if it is true ?

Also i wanted to know if drinking these diet sodas have any ill effects long term /short term both.

To my mind -- and I am not a food scientist -- drinking diet sodas just puts extra, unecessary chemicals into your system, when plain water would do a better job of slaking your thirst. That's just MY preference, though.

Does carbonated soda spur bone loss?
Mary Spoon

A caller asks: I’ve heard that the acid in carbonated soda contributes to the drinker’s bone loss. Is that true? Is there an association between soda consumption and osteoporosis?

Scientists have seen an association for some time between consumption of soda pop and a risk for weakened bones, but they haven’t been certain why. One theory has been that the phosphorus in carbonated beverages contributes to calcium loss from bones. The reasoning has been based on the idea that phosphorus (usually listed on soda as phosphoric acid) binds to calcium in the gut, thereby preventing the calcium from being absorbed and making its way to bone.

Another theory is that calcium and phosphorus need to be eaten in a particular ratio to maintain bone health. Presumably, a lot of phosphorus without any calcium whatsoever – like in soda pop – could throw off the delicate calcium/phosphorus balance.

But a new study, conducted by researchers at Omaha’s Creighton University Osteoporosis Research Center, suggests the mechanism is much simpler: too many carbonated beverages simply replace calcium-rich milk in the diet. It’s not a new hypothesis; dietitians have for years been lamenting the fact that the public has been increasing soda intake while reducing milk consumption. But the study helps strengthen the argument.

In a carefully controlled experiment, the researchers gave a group of several dozen women different soda pops on different days, some containing phosphorus (such as Coke), and some without it (like Mountain Dew and Sprite). The women excreted no more calcium in their urine after drinking the phosphorus-containing beverages than the other ones, so it did not appear that phosphorus was hindering uptake of calcium by the gut and then sending it out of the body. The only thing that made a difference was the caffeine in some of the soda brands, which caused extra calcium excretion. But even that was made up for with reduced calcium in the urine later in the day.

The bottom line, the researchers say, is that the adverse effect of carbonated beverages on bone health lies not in what these beverages contain, but in what they do not: the needed nutrients for bone health.

Other mineral researchers concur. “Milk displacement is responsible for significant declines in the amount of calcium Americans are consuming today, which is a far greater threat to bone density than the amount of phosphorus in a can of soda,” says Bess Dawson-Hughes, MD, chief of the Calcium and Bone Metabolism Laboratory at Tufts. James Fleet, Ph.D., of Purdue University’s Department of Foods and Nutrition adds “milk is a vital source not only of calcium but also of vitamin D. Drinking a limited amount of soda is not detrimental to your bones, but milk and other calcium-rich foods have to remain daily staples.”

I do alot of driving from project to project so I listen to alot of radio. On Dr. edealls medical minute show once I heard him say that if you are going to drink soda according to this one study that you should drink pepsi over coke because it has citric acid and phosporic acid and the combination of the two some how inhibited the growth of kidney stones. So if that is the case then it would seem to follow that there would be some correlation because aren't kidney stones calcium deposits? Water is best though and is the number one fastest growing segment in the beverage business. At our golf course we sell doulbe the water to anything else soda related.
