How Much Caffeine is Really in That Soda? 332

The Fun Guy writes "The Institute of Food Technologists summarizes some recent research on food. All things considering, it should settle some arguments among geeks about the caffination of beverages. 'Caffeine is a well-known stimulant added as an ingredient to various carbonated soft drinks, but which drink contains the most, and how can consumers know? A study in the Journal of Food Science used high-performance liquid chromatography to analyze the caffeine contents of 56 national-brand and 75 private-label store brand carbonated beverages. Caffeine contents ranged from 4.9 mg/12 oz (IGA Cola) to 74 mg/12 oz (Vault Zero). Some of the more common national-brand carbonated beverages analyzed in this study were Coca-Cola (33.9 mg/12 oz), Diet Coke (46.3 mg/12 oz), Pepsi (38.9 mg/12 oz), Diet Pepsi (36.7 mg/12 oz), Dr Pepper (42.6 mg/12 oz), Diet Dr Pepper (44.1 mg/12 oz), Mountain Dew (54.8 mg/12 oz), and Diet Mountain Dew (55.2 mg/12 oz). The authors found that store-brand beverages generally contained less caffeine, and they also suggest that consumers would benefit from having the actual caffeine content labeled on the beverage.'"

    Sorry to bring this up, but that unit just strikes me as absolutely ridiculous (mg/12 oz).
    Why measure per 12oz instead of per oz? Actually, why not skip the oz and go all in on the metric system, instead of that half-assed job?

    Can anyone explain this to the people (like me) east of the Atlantic?

    I've been drinking Caffeine-free (NOT DIET!) Coca-Cola ice it came out on the market a few years ago, after consuming who-knows-how-much caffeine over the course of my lifetime previous to its release. It has all the sugar and calories of regular Coke, but zero caffeine, and tastes virtually the same (although perhaps a tiny bit sweeter, as it lacks the bitterness of the caffeine). I bring a case to the office every week or two for my own consumption. People always ask me about it, as it comes in a shiny, golden coloured can, as if it were Coke for the super-rich or something.

    Unfortunately, it's brutally difficult to find. I went through a three-month stretch a year or so ago where I simply couldn't buy it at all. So now I keep a small stock-pile. I know of one store in the area that carries it (I used to know at least four, three of which have stopped carrying it), and they often get 3 or 4 cases every week or so. Recently, however, they suddenly had more than a dozen cases on their shelf, and I've been slowly buying it up.

    Anyhow, if you're looking to get your body out of the caffeine-consumption cycle, but don't want to give up that sweet, sweet nectar, look around for it. It's good stuff. Maybe if I can convince more people to drink it, it will become possible to find it in more places and more sizes (I've only ever seen it in 12-can cases and 2 litre bottles, and never in a vending machine, and only very rarely in a convenience store as single cans).

    Yaz.

    I think the more important problem is that you were drinking a very, very large amount of it. Most people don't drink nearly that much of any caffeinated beverages and thus, tend not to have serious problems with blood pressure, sleeplessness, or addiction. In short I think that your addiction (and resultant conspiracy theory that the intent is to addict you) is more related to your own usage scenario than to anything to do with the drink itself.

    The LD50 for caffeine in humans is about 150-200mg *per kilogram of body mass*

    That means that an 80kg adult male (180 lbs) would have to ingest 12-16 *grams* before he has even a 50% chance of dying. Obviously some people would fall to much less that this, but it seems clear that unless you're trying REALLY REALLY hard, you won't be experiencing any permanant troubles from ingesting caffiene in beverage form.

    there is little that is nastier than a cold cup of coffee.

    ... other than a warm, flat glass of coke.

    That's two conversions required to work with any system, be it American or SI.

    Rather, it's one conversion to work in either system. And it's the imperial, not the American system.

    Gosh, because there's no way alcohol could be more harmful than caffeine, especially when drinking to the point of getting "too drunk."

    All of them are natural, organic
    What does that mean? Is the soda found in nature?

    there is no corn syrup or other fake crap.
    Corn syrup is fake? Really? So sugarcane just "naturally" and "organically" becomes sugar?

    Drop the caffeine habit, you'll love yourself for it both health and money wise.

    If you're worried about your health, why on earth would you be getting drunk. Switching from caffeined softdrink to water might be healthy but switching to beer not so much!
