Why It's So Hard To Predict How Caffeine Will Affect Your Body 212

Posted by Soulskill from the mainlining-crushed-penguin-mints-is-not-the-best-plan dept.
carmendrahl writes "Emergency-room visits linked to caffeine-laden energy drinks are on the rise. This gives scientists who'd like to see caffeine regulated the jitters. But the U.S. Food and Drug Administration seems to be dragging its feet on regulating caffeine content in food and drink, because people have different sensitivities to it (abstract). Currently, caffeine-rich products like Monster Energy get around the rules because they're marketed as dietary supplements. 'Caffeine gets cleared from the body at different rates because of genetic variations, gender, and even whether a person is a smoker. For this reason, it’s difficult to set a safe limit of daily consumption on the compound. Physiological differences, as well as differences in the way people consume caffeine, have tied FDA in knots as it has debated how to regulate the substance. ... The toxic level in humans, about 10 g, is roughly the equivalent of imbibing 75 cups of brewed coffee (in 8-oz mugs) or 120 cans of Red Bull over a few hours. But that lethal limit can vary widely from person to person, experts say."

    The part about caffeine that is dangerous is that, like other stimulants, it gives the impression of improved brain performance without really delivering it. A fatigued person propped up with caffeine still makes mistakes related to fatigue. The other effects like jitters and palpitations is probably harmful to the heart in the long term also but it's less of a hazard to others.

Something about the caffeine I get through coffee is different. It actually makes me feel alert and awake. So is there some other chemical in coffee that increases the effectiveness of caffeine for me, or is the caffeine delivered differently? Does it have a slightly different composition? I don't know. But its a difference I can definitely feel.

        Gut clogging quantities of HFCS most likely. Unless you drip a quarter cup of corn syrup into your coffee as a control.
        The no-cal versions have vast quantities of strange sweeteners.

        If you want a real control, assuming you can still legally buy caffeine pills OTC (or maybe over the net) like Vivaran (sp?) you can simply pop pills equal to however many milligrams you'd like. Drink some water to wash it down and maintain hydration and its almost guaranteed to be healthier for your innards than the additives in either drink.

        Its rather telling WRT lethal dosages that they used to sell vivarin caffeine pills in 50 packs (implying you can chug them all and live) but sleep aid pills in 5 packs (implying more than a couple and you're dead). Then again they sell tylenol in 500 capsule buckets at sams club so maybe my theory doesn't apply.

          Put this stupid myth to rest. There is no known reason for-- nor observed effect-- HFCS to be processed significantly differently in your body than straight up sucrose. In 1 of the 2 most common mixtures, it has 1% more glucose (better for you); in another it has 6% more fructose (a bit worse for you). Either way, its a wash, and chemically it has the exact same stuff that sucrose has, just already partly broken down into its constituent sugars (sucrose = glucose + fructose).

          Its seriously irritating that of all things for people to worry about, they quibble about WHAT KIND of sugar is being imbibed (which has negligible effect) rather than the amount. Its like wondering whether the lake you are drowning in is fresh or brackish, and what health effects that might have on you.

            Well, technically each of these sugars is metabolized somewhat differently, and uses up different amounts of B vitamins in the enzyme conversion chain. IANA biochemist but it takes, IIRC, two molecules of B-something to assist in the splitting of a sucrose molecule to its constituent frucose and glucose molecules, and so forth. I forget which vitamins are used where. So again, different people will be affected differently depending on your vitamin levels as well as your phenotype.

            Funny how these things go, it wasn't that long ago that you could buy fructose at the health food store, as a 'healthy alternative' to sucrose - coming from fruit and all.

            • Once again, the commonly touted sucrose is broken down in your body into what is basically an odd-ratio HFCS mix (Sucrose would become 50-50 glucose-fructose, while HFCS is usually 42-55 or 53-42 plus 3-5% "other sugars")

          • See below for correction, ratio was slightly off, but not by much.

            Put this stupid myth to rest.

            You mean the myth that using fructose in place of sucrose makes no difference?

            The simple fact that a simple sugar has already been broken down to a simple sugar means that it will flood the system much more quickly than a more complex sugar that needs to be converted before transport. If we don't need to pay attention to what the sugars are, then explain why cellulose (long chains of glucose) are indigestible, while simple glucose floods the system almost as soon as it is ingested.

            Yes, sir, the metabolic paths for glucose and fructose are different, and flooding the liver with massive amounts of fructose rapidly does result in a different effect than a slower appearance of glucose. The liver and endocrine systems need time to react to the influx of the sugars no matter what they are, so a rapidly appearing slug of one kind of sugar can easily overwhelm the regulatory mechanisms of the body and cause harm where a slower appearance of a different sugar does not. That harm may only be an unnecessary conversion of sugars to glycogen and fat, but in the long term that results in obesity and that can be harmful.

            You're talking to a diabetic who has monitored his blood sugar for years through all kinds of experiments with different sugars, who can tell you that the "glycemic index" and "sugar alcohols" information is a truly dangerous myth, along with the sugar industry shills telling us that there is no danger from HFCS. Yes, you're right that cutting sugar overall is a good thing, but trying to claim that if you are going to down a sugar laden drink that it makes no difference is just parroting the sugar industry media flacks. You'd point to data denying global warming or the link between smoking and cancer as being from an industry source, why are you so quick to accept data from the sugar industry?

        Placebo effect maybe?
        Asking this because I used to play a prank to a friend of mine whenever he came for dinner: He always complained about being unable to fall asleep after drinking coffee, so since we all drank coffee after dinner I started giving him decaf without him knowing.
        Guess what, when asked the day after or a couple of days later he would say that he had difficulty falling asleep with decaf as well... Well, he didn't knew it was decaf.
        After a couple of repeats I finally told him that we were giving him decaf.... and I switch, started giving him coffee again. You got it, when asked he would say that he didn't had any problem falling asleep.

        But then again, it may not be the case with you.

        • Just remember that even decaf can have as much as 1/3 of the caffeine content remaining. Filtering the caffeine out is a bit tricky process.

          Still, it is very well possible that your friend indeed experienced a placebo effect, as you said.

      This is actually scientifically not true. Caffeine affects us by blocking the chemicals that make us tired. As a result we are not only feeling more awake, but actually are more awake. The crash that occurs is because the chemicals that have been blocked thus far, are in a waiting pattern until their blockage disappears after which they flood the receptors. I do agree though, there is a good amount for false positive when it comes to perceived performance though.

        So, then, a GREAT first step would be to require companies to label how much caffeine is in their product, so we can have a relative scale.

    • They are both very different chemically. People who are sensitive to Caffeine might not be sensitive to alcohol. Caffeine was mostly a black box up until the last 5 years. It works by messing with a couple of hormones, Estrogen and something else that I can't remember along with who knows what else. It is a stimulant so it wires you up. Alcohol on the other hand works with different hormones, testosterone being one of them. It also impedes the brain as a depressant. Even though you see that they are similar
  • Every drug affects every user individually, and to further confound things, the effects often vary in the individual user from one dose to the next. Alcohol, marijuana, Advil, and opiates are each subject to personal efficacy variables such as frequency of use, innate tolerance, mood, sleep patterns, amount of food ingested, and undoubtedly many more. This is the very thing that separates the thinking man from the drug abuser. I don't need to be told via a County burn ban not to burn trash when it hasn't

    How can they regulate this? You can go to almost any grocery/goods store and buy a 33 ounch can of ground coffee. They would surely let you buy as many of these as you wish to. Since a bunch of stupid white kids drink monsters too fast they now need to pursue regulation of it? Really? I know, maybe they should pass a law stating that energy drinks cannot taste better than coffee so as to damper the enthusiam with which these drinks are imbibed. Dumb.

    Caveat of my own stupidity: While in the dorms one weekend night I drank two pots of coffee in a relatively short span of time. What would that be? Maybe 2x 6x cups of coffee? So somewhere around 1200mg or so? Anyways my stomach hurt, my head kinda spun, and my legs twitched a little as I laid in bed wondering when I would fall asleep. I learned from that to take it easy.

  • Why doesn't the FDA do like any other governmental or lawmaking entity does and write the laws to the weakest denominator and make everybody else suffer?

  • I hope the hacker community has grown out of the old culture of everyone robotically drinking coffee and caffeinated sodas. Sometimes at workplace it's sad to see someone churning code and a huge pile of empty energy drink cans aside him. Like, is this some kind of tough profession through which you have to be constantly mildly drugged to cope. Slightly disgusting.
  • I'm not so sure regulate is even the right word. They might make a recommendation for maximum daily allowance, but unless they're going to make it a federally controlled substance (i.e. on par with cocaine), the FDA will in fact have no degree of control - or "regulation" if you will - over people's personal intake. Even alcoholic beverages are not "regulated" for quantity of consumption. They may charge a tax on it... they may make a test that measures how much is too much when operating a vehicle... but t

  • For Christs sakes just read the fucking studies. Almost everything about Caffeine is good... The ONLY long-term down side of caffeine is a suspected slight increase risk in ovarian and breast cancer. They of course have no proof of this, and it's only suspected because caffeine leads to the fluctuation of plasma sex hormones and SHBG in women. But there are no studies that have shown it actually leads to any sort of increase in cancer risk.

  • "The toxic level in humans, about 10 g, is roughly the equivalent of imbibing 75 cups of brewed coffee (in 8-oz mugs) or 120 cans of Red Bull over a few hours."

    Is that 75 cups of US coffee or real coffee like we drink in the rest of the world?

    • It completely depends upon location and brew. Cuban and Turkish coffee are closer to rocket fuel than traditional medium roast coffee, and have differing amounts of caffeine in them.

      ...and you can't say "the rest of the world" without giving a country. Almost every country has its own method of preparation. Even differing parts of the US have different preparation methods (New Orleans vs. Miami, for example).

  • There is coffee out there that has as much naturally-occurring caffeine in it as many energy drinks. If you're going to start regulating caffeine content in any sort of drinks, then you have to do it for coffee as well. That is why it won't be done, and that's why it hasn't already been done: nobody is going to screw with coffee.

    Leave energy drinks alone. The number of people having serious problems because of them aren't that many, and the ones who do are being excessively stupid about their consumption o

  • A lot of those big-can drinks are more than a single serving, presumably to let them load the caffeine beyond the maximum allowed by law. So even if the consumer is savvy enough to check the label for caffeine dosage they might not notice the serving size and forget to multiply the dose by serving if they're planning to drink the whole can. If you're doing multiple cans a day, it starts to get easy to see why we're having a problem with it now despite a couple of centuries of coffee abuse (Grandpa used to d

    You thought the protests against SOPA and PIPA were bad? Move against caffeine and they'll look like a walk in the park. It's not just geeks: pretty much every white collar profession (and more than a few blue collar ones) runs on caffeine. That includes lawyers and lobbyists. Just put the Federal Register down and back away slowly.
