Coca-Cola is also absolutely loaded with phosphoric acid. It's got a pH almost as low as white vinegar. They put all that acid in it because they have to in order to keep all that sugar (I think it's 42 grams or something per 8 oz) dissolved in solution. I know that sugar is very bad for people, but that is a whole lot of acid to be drinking, isn't it?

Bad for your teeth maybe, but phosphoric acid isnt unhealthy. I mean stomach acid had a pH of 1.5-2.0; and thats due to the presence hydrochloric acid.

What I have read is that regular intake of that kind of acidic liquid eventually leaches calcium out of your bones as your body tries to compensate and balance pH. I'm no doctor but I think there's a big difference between the appropriately local low pH of stomach acid and ingesting a pH 3 liquid every day.

You should probably re-check your facts. You can dissolve almost 2g of sugar per mL of water. Phosphoric acid has nothing to do with keeping sugar dissolved. The acid is for keeping CO2 dissolved. Which is also how the body is regulates pH, through CO2 and bicarbonate, not calcium.
