It's a well-documented fact that soda is terrible for your health. Most pop drinks are laden with sugar and caffeine, in addition to the degrading affects of carbonation on tooth enamel. So, what are you going to do, drink water? Blegh! That's why mankind invented cool refreshing seltzer, for when you want excitement for your tongue without degrading the health of your body.

Illuminated by God's fizz.

Like all fun things, the illusion that seltzer is good for you—or at the very least neutral—is getting dispelled. Last September, the BBC compiled research on the effects of seltzer and debunked or confirmed people's worries about it. The good news is that seltzer is not hurting stomachs with all the widdle bubbles: 

The result is that water contains the weak acid, carbonic acid. If you gulp it down it can of course give you hiccups or indigestion. But what if you drink it at a more measured pace? Is there any truth in the idea that it harms your stomach?

Quite the reverse, it appears. In a small but double-blinded randomised trial, patients with frequent dyspepsia or constipation were assigned to drink either still or sparkling water for 15 days. Then they were given a series of tests. Both conditions improved in the people drinking sparkling water and showed no improvement in those drinking tap water.
