Carbonated beverages are associated with out-of-hospital cardiac arrests of cardiac origin, according to results from the All-Japan Utstein Registry presented for the first time today at ESC Congress. The study in nearly 800,000 patients suggests that limiting consumption of carbonated beverages may be beneficial for health.

"Some epidemiologic studies have shown a positive correlation between the consumption of soft drinks and the incidence of cardiovascular disease (CVD) and stroke, while other reports have demonstrated that the intake of green tea and coffee reduced the risk and mortality of CVD," said principal investigator Professor Keijiro Saku, Dean and professor of cardiology at Fukuoka University in Japan. "Carbonated beverages, or sodas, have frequently been demonstrated to increase the risk of metabolic syndrome and CVD, such as subclinical cardiac remodeling and stroke. However, until now the association between drinking large amounts of carbonated beverages and fatal CVD, or out-of-hospital cardiac arrests (OHCA) of cardiac origin, was unclear."

In other words, put the soda down and back away slowly... Is there a safer way to make our beverages bubbly?

    > I wonder what effect carbonated water would have.

    None. The article itself says that "mineral water" had no association. Mineral water is just carbonated water with some extra minerals like calcium, magnesium, bicarbonate, etc. One significant difference between mineral water and plain carbonated water is acidity. Carbonation creates carbonic acid which lowers the pH of the water to around 4.5 while the minerals, particularly bicarbonate tends to buffer the acidity so that mineral water tends to much closer to a neutral pH of 7.

    That probably doesn't make much difference to your bloodstream, but it does make a difference to your teeth - low pH drinks promote tooth decay because the bacteria that eats your enamel thrives in an acidic environment. So mineral water is better than plain sparkling water aka seltzer.

    I only drink mineral water because I am addicted to bubbles in my drinks. Flat water is just too boring. I built a poor-man's carbonation system [popsci.com] that lets me carbonate 2 liters for a couple of pennies. Here's an 8-minute video [youtube.com] from another guy who did the same thing. Unlike him, I bought my co2 tank new rather than scavenge because you can't know if the tank has containments like lubricating oil in it. Always get your co2 refills from a place that does fills for restaurants or medical users because they will keep containments out of the refill process.

    Here are the ingredients list for homemade mineral water clones. [khymos.org] San Pellegrino is particularly simple to clone, just 1 teaspoon of Burton's Salts [amazon.com] per liter.

    Mineral water is not necessarily carbonated. But carbonated water is a carbonated drink.

    Now, that is interesting. Just yesterday I was looking for something like that. I have a Sodastream, the refill for the CO2 containers are insanely expensive (more than buying the carbonated water in the long run). Alternatively, I'm looking into an adapter to refill the Sodastream CO2 container myself from a bigger, cheaper CO2 bottle

      I tried that when I started. Or rather I bought an adapter for the big tank and just hooked it directly to the sodastream so I didn't have to dick around with the paintball sized tank.

      Downside is that the sodastream mechanism is too leaky too carbonate strongly and is very wasteful of co2. Upside of the shaker is you can get higher carbonation levels and a lot more liters per tank by doing it with the shaker because it has nearly zero waste. Also helps with upper body strength - I shake it a lot more vigorously than the guy in the video.

      Downside of the shaker is that you have to shake it so it is less convenient, but that is mitigated by doing 2 liters at a time instead of whatever size bottle your sodastream has. I bought three of those carbonator caps, 1 of them was leaky from day 1, the other two are fine 3 three later and I do about 4 liters per day. The leaky one is not leaky enough to matter if you intend to pour a drink immediately after shaking, I just can't leave it on as a cap over night.
