Oooh. Diet Fizzy Coke. Bad Susan. When you start tapering for Chicago, taper the carbonation right out of your intake.

...and I quote(http://www.ultrunr.com/soda.html):
"Coke and other soft drinks are acidified with phosphoric acid ( see the list of ingredients on the side of the can/bottle ). When food passes from the stomach to the small intestine, bicarbonate is added ( by the digestive apparatus ) to raise the pH. Under the acid conditions of the stomach, the calcium in food is available, but when the pH goes up in the small intestine, the calcium reacts with the phosphate from the soda and precipitates. In that form, calcium phosphate, it is not available for absorption.

This has nothing to do with the color of the soda.

Drinking lots of soda on a daily basis is not a good idea for many reasons. In addition to calcium interference, sodas provide empty sugar calories - no vitamins, no minerals, no fat, no fiber, no salt.

A can or two once in a while is nothing to worry about, but if you're drinking more than a can per day, you're cheating your body out of nutrients it could get from less refined sources.

It is the contention of some food scientists that some major food suppliers deliberately omit important nutrients from their products so that the under-nourished body will eat more, seeking that which it has not been given. As one man put the question: Who in the audience has eaten just one Oreo?
