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.'"

        Just picked out a few... Report says:
        - 38.9 for Pepsi, database says 38.
        - 33.9 for Coke, db says 34.
        - 42.6 for Dr Pepper, db says 41.
        - 46.3 for Diet Coke, db says 45.
        - 55.2 for Diet Mountain Dew, db says 55.

        So it looks pretty accurate at least, from a quick glance.

        To give some perspective as you're looking at drinks with 40 or 50 mg per 12 oz bottle, note that a regular cup of coffee can have around 60-120 mg per cup, and a Red Bull seem to have around 80 mg per can.

        There's a bit of a story behind the limit in Sweden, because Swedish drinks use to have a limit of max 100 mg caffeine / liter. Åbro, the Swedish producer, has howerver gained permission of using up to 150 mg/l. A US Jolt bottle seem to have 140 mg caffeine, and one in Sweden around 78 mg / 33 cl bottle (or 23 mg/100 ml, about what you say).

      I've posted about my caffeine free lifestyle on here before but I'm too drunk (it was 97F today) to look it up while I'm mobile.

      I used to drink up to a case of Coke (in cans) daily during college and once I was done with organized athletics I decided to switch to diet to keep the calories down. I hated the way diet colas tasted so I went with the new diet drink at the time, Diet Cherry Vanilla Dr. Pepper (aka, to my circle of friends, as Liquid Crack).

      After several months of drinking it, I as up to at least 4 or 5 20oz bottles and 12+ 12oz cans daily. I wasn't having any sugar guilt so I didn't think anything of the caffeine's effect on my system.

      After numerous sleepless nights in terror because of a pounding chest, I went cold turkey. That 7 day migraine sucked more than anything ever before.

      Now, over 1.5 years later, I'm much better off. I am convinced that the high caffeine levels of diet soda is to compensate for the lack of sugar and to force addiction over the flavor.

      My BP dropped to near normal levels (I was on 150MG+ of two different BP meds prior to the caffeine habit kick) which is likely a combination of the drop in caffeine as well as elevated sodium levels in diet soda and I feel a ton better overall.

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

        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.

          I was taking 100 to 125mg of Toprol XL and 20 to 40mg of Lisinopril (depending on what the Dr was trying to accomplish as I never got it fully under control). My BP, un-medicated, was averaging 190 to 210 over 90 to 100.

          Now I'm on 20mg of Lisinopril (to bring it further under control than it is) and I'm currently at 110 to 125 over 75 to 80. With my family history this is what the Dr recommends. I'm fine with keeping it under control in this manner.

          For a while I was down to 10mg of Lisinopril but after changing Dr's, they moved me to 20mg to keep it a bit lower than what they consider "good" for good measure.

          As far as exercise/diet goes, no, I didn't change anything other than the soda. My family history predisposes me to this and even when I was in 100% athletic shape my BP was 180/100 regularly. They attributed it to the distance events I trained for and became concerned only after I stopped. After ending the soda kicks, I didn't need the meds anymore and I began training again (after a 5 year hiatus) and found that my pressure INCREASED. This completely baffled the Dr but such is my life.

          Good luck yourself.

      896 mg assuming each shot is similar to the 1 fl oz reference espresso in the USDA Nutrient database.

      I'd be a bit careful. Depending on the speed with which you drink your coffee, you might be getting close to the toxicity level of caffeine. Unfortunately, there is very little information on what that is and how it relates to clinical effects. I found this paper interesting, though.

      • Starbucks' website lists 75mg per shot, so we're talking 1.05g (or 1.025 gi - darn those coffee manfacturers for not using standard binary units like the rest of the computer industry)
      • Unfortunately, there is very little information on what that is and how it relates to clinical effects.

        Caffeine's LD50 is 192mg per kg, so you'd need about 15g, or more than 200 shots, to have a reasonable chance of topping yourself with espresso. The metabolic half-life of caffeine is about 5 hours, so you'd need to be doing the shots fairly quickly too.

        At least one person has survived ingesting 24g, so while you can kill youself, you'd be more likely to knock yourself unconscious bouncing off the wall

      I've only had dual quads on ice, but I get the feeling the people who work at Starbucks start their days with at least that much. Spread over about 4 hours it maintains your buzz nicely. Since it's iced, you don't have to worry about oxidation and bitterness too much. I like a doppio per day but if you really have a lot to do, quad or dual quad will really keep you going. Plus they are cheap compared to the "lattes": $1.88 for a dopio with tax, 55 cents per shot and if you tip them every day for a while it'll get cheaper ;) After a few weeks I like to detox over a weekend with no caffine, otherwise "caffeinism" can set in:

      In large amounts, and especially over extended periods of time, caffeine can lead to a condition known as "caffeinism." Caffeinism usually combines "caffeine dependency" with a wide range of unpleasant physical and mental conditions including nervousness, irritability, anxiety, tremulousness, muscle twitching (hyperreflexia), insomnia, headaches, respiratory alkalosis[51] and heart palpitations.[52] Furthermore, because caffeine increases the production of stomach acid, high usage over time can lead to peptic ulcers, erosive esophagitis, and gastroesophageal reflux disease.[53] However, since both "regular" and decaffeinated coffees have been shown to stimulate the gastric mucosa and increase stomach acid secretion, caffeine is probably not the sole component of coffee responsible.[54]

      There are four caffeine-induced psychiatric disorders recognized by the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition: caffeine intoxication, caffeine-induced anxiety disorder, caffeine-induced sleep disorder, and caffeine-related disorder not otherwise specified (NOS).

      Other side effects of caffeine overuse include: dizziness, tachycardia, blurred vision, drowsiness, dry mouth, flushed dry skin, diuresis, loss of appetite, nausea and stomachaches.[55]
      -- From Caffeine Article [wikipedia.org] at Wikipedia..

      Yeah, I drank a lot for many years but it's always good to detox once in a while. Since Caffeine has a half-life in your system you can never really get rid of all of it so your base levels go up over time, especially if you have 400+mg a day. Drink tea and take a real asprin on the first day of a 3 day detox and you'll thank yourself.

      Oh, and if you're looking to prolong the half-life of coffee, you need a CYP450 [wikipedia.org] inhibitor--such as Bergamottin [wikipedia.org] or Naringin [wikipedia.org], both of which are found in fresh grapefruit juice, peel and seeds.. It's under debate which one actually affects the CYP450, but it works--trust me. So, do yourself a favor and instead of taking 600mg of caffine, take 200mg with a grapefruit juice and enjoy the better effects.

    Abstract

    ABSTRACT: Caffeine is a well-known stimulant that is added as an ingredient to various carbonated soft drinks. Due to its stimulatory and other physiological effects, individuals desire to know the exact amount of caffeine consumed from these beverages. This study analyzed the caffeine contents of 56 national-brand and 75 private-label store-brand carbonated beverages using high-performance liquid chromatography. 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 with their caffeine contents 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 Wal-Mart store-brand beverages with their caffeine contents were Sam's Cola (12.7 mg/12 oz), Sam's Diet Cola (13.3 mg/12 oz), Dr Thunder (30.6 mg/12 oz), Diet Dr Thunder (29.9 mg/12 oz), and Mountain Lightning (46.5 mg/12 oz). Beverages from 14 other stores were also analyzed. Most store-brand carbonated beverages were found to contain less caffeine than their national-brand counterparts. The wide range of caffeine contents in carbonated beverages indicates that consumers would benefit from the placement of caffeine values on food labels.
    Introduction

    Caffeine, 1,3,7-trimethylxanthine, is an odorless, slightly bitter substance found in numerous plant species (Tarka and Hurst 1998). Extracts derived from these plants, such as coffee and tea beverages, naturally contain caffeine and other methylxanthines. Caffeine is intentionally added as an ingredient to many carbonated soft drinks, including colas, pepper-type beverages, and citrus beverages. Although soda manufacturers may explain that caffeine contributes to the flavor of soft drinks, only 8% of adults were able to differentiate between caffeinated and caffeine-free colas at the concentration of caffeine contained in most cola beverages (Griffiths and Vernotica 2000). These beverages appeal to many consumers because of the stimulatory effect caffeine provides.

    Caffeine has drawn more attention in the past decades due to its widespread consumption and physiological effects beyond that of its stimulatory effect (James 1991; Bernstein and others 2002; Mandel 2002). Caffeine is quickly absorbed by the body. The human salivary caffeine level, which indicates the extent of absorption, peaks around 40 min after caffeine consumption (Liguori and others 1997). Various physiological effects on the central nervous, cardiovascular, gastrointestinal, respiratory, and renal systems have been reported (Nehlig and others 1992; Spiller 1998; Hartley and others 2004; Savoca and others 2005). For example, Hartley and others (2004) reported that caffeine causes a mild elevation in blood pressure. In addition, caffeine's diuretic effect is widely known (Spiller 1998).

    Various governmental bodies have specified the maximum level of caffeine allowed in carbonated beverages. The U.S. Food and Drug Admin. limits the amount of caffeine in carbonated beverages to a maximum of 0.02% (FDA 2006). Therefore, the highest legal amount of caffeine allowed in a 355 mL (12 oz) can of soft drink is about 72 mg. Likewise, Canada limits caffeine to cola-type beverages at a level of 200 ppm or about 71 mg/12 oz (Dept. of Justice 2007). In Australia, the maximum caffeine level in cola-type beverages must not exceed 145 mg/kg or about 51 mg/12 oz while in New Zealand, the caffeine level is limited to 200 mg/kg or about 71 mg/12 oz (FSANZ 2000).

    The amount of caffeine contained in various foods and beverages has been analyzed, including coffee (Bell and others 1996), tea (Hicks and others 1996; Friedman and others 2005; Pena and others 2005; Yao and others 2006), carbonated beverages (Bunker and McWilliams 1979; Strohl 1985; Grand and Bell 1997; Pena and others 2005), and chocolate products (Caudle and others 2001; Tokusoglu a

      Also, what do they put in Coke that caffinates it? Do they just pour an amount of pure caffine in, or what?

      The "Cola" in Coca-Cola stands for kola nut extract, which used to provide the bulk of caffeine. But after several reformulations of Coca-Cola, less actual kola is in the formula, and most of the caffeine is now pure caffeine. Caffeine is a base, and Coke has phosphoric acid to disguise the bitterness.

      Personally, I like the taste of Coca-Cola Zero [wikipedia.org] a lot better than that of Diet Coke. I can tolerate Diet Coke only in a fountain mix that emulates C2 [wikipedia.org] (50% Coca-Cola, 50% Diet Coke). But will Coke follow the example of Diet Pepsi Max in introducing a new higher-caffeine formulation? And will it be called Crack-a-Cola?

    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.
