    Is Coffee bad for you? Depends on your genetics


    by jamesrl ·

    I listened to the author of the study on an interview this morning – not the quirks and quarks one (a radio science show) , but a general interest morning show. They brought this guy on because Coke is launching a coffe/hybrid beverage.

    Turns out, there are 2 type of people in the world, caffeine wise. Fast metabolizers and slow ones. For the fast ones, coffee reduces the risk of heart attacks, for the slow ones, it increases the risk of heart attacks as much as heavy smoking.

    How do you know which you are? You don’t. It has nothing to do with your nervous systems tolerence for caffeine. It is how fast your liver processes/breaks down cafeine. As the author explained, just because you have a coffee at 3pm and stay up all night doesn’t mean you are necessarily a slow metabolizer.

    Something to think about over your next cup.

      You caused this worry, so I’m sending you a piece of my liver for analysis. Just ignore the portion that’s rotted away by alcohol.

        The reasearcher interviewed this morning suggested that he had tested himself, but refused to say which one he was. He only said that his coffee habits were appropriate to his genetic type. Many of his friends asked to be tested.

        Its a toss up.

          Sautee it with some onions in a little olive oil. Better yet, ask JD for a recipe.

          I’m sticking to my 2 – 3 cups per day. That’s about 1/2 of my father’s consumption and he lived to 86. And you can’t really call what he drank coffee. It was more like a thick mud consisting of normal brewed coffee, run thru a coffee percolator, then a drip coffee maker with some instant coffee added, finally desiccated to remove excess water to give it more coffee flavor. It was never analysed to determine the amount of ceramic cup dissolved into it, but I assume that it ate into the cup significantly.

          It was funny to hear him complain about restaurant coffee. Apparently there’s not a single restaurant in North America that knows how to make coffee properly.

      I am a fast metabolizer… I hope

      I have been drinking an average of three to four cups of coffee a day for well over 30 years. And I mean coffee- not hot bean drink.

      I have ADHD that has been treated in the past successfully with amphetamines. The older I get, the less willing I am to take something that harsh. I discovered long ago that coffee would do many of the same things- improve focus, reduce impulse, etc. I can also get a similar benefit from guarana. Oddly, I don’t get the same benefit from sodas containing caffeine. I am sensitive to the sugar and most sugar substitutes.

      Interesting reading!

        And I have been drinking that much coffee for decades. If I was the wrong genetic type it would have killed me long ago, so I must be safe! LOL

      Too many studies

      by onbliss ·

      In reply to Is Coffee bad for you? Depends on your genetics

      …sometimes I feel there are just too many studies. Sometimes studies appear to contradict each other, sometimes we have to read the fine print or notice the nuances or exceptions.

      I am almost coming to the conclusion that we ought to not unduly worry about all these things. The key to me seems to be that we ought to get in lots of physical activities in our every-day life.

      note to myself: practice what you preach 🙂

        In reply to Too many studies

        It was the contradictory studies that were the reason for this study. There had to be some explanation for why some people had benefits and others had risks.

        According to the study, if you are one of the slow metabolizers and you drink 4 or more cups a day, its as bad as being a heavy smoker in terms of an increased risk of heart attack. Something to think about.

          It was in a study not long ago that people that drink two or more cups of coffee are less prone to alzheimer’s disease.

          Which do you want to go, your heart or your mind?

          I don’t mind! 😀

          For various reasons, which I won’t go into (TMI), I believe I am a fast metabolizer. Good thing, too, because I’m good for 10-15 cups a day.

          It’s funny though, that the majority of studies I’ve seen about coffee and smoking say that coffee mitigates the effects of nicotine. Now, they say coffee can be as bad as smoking?

          My late husband smoked and drank coffee. From that he developed emphysema and bladder cancer. The cancer metastasized even though his bladder & prostate were removed. He lived only a year and a half after the surgery.

        the problem is…

        by colonel panijk ·

        In reply to Too many studies

        …not [i]too many[/i] studies, but media hype about them. Yes, some studies are poorly done, but the real problem is that the news media, ever hungry for controversy and screaming headlines, pounces on every study likes it’s the Final Word on a subject.

        [i]I am almost coming to the conclusion that we ought to not unduly worry about all these things.[/i]

        An excellent attitude. Don’t worry if a single study comes out screaming, “two cups of coffee combined with a Twinkie is guaranteed to cause nose hair!” When a contradictory study comes out, you’ll only be confused if you turned your life upside down based on the first. The time to worry about medical studies (and change your lifestyle) is when a [i]whole bunch[/i] of them come out over time (not all at once) and they tend to come to more or less the same conclusion. Give the peer review process time to weed out the junk, and see what’s left.

      I am 31 and up until two months ago as of tomorrow I drank around 4-5 cups of regular coffee, no cream, suger, etc. Just plain old coffee. I have done this since I was about 17 years old and just stopped cold turkey.
      The big thing that I notice is how much nicer my teeth look and my stomach feels!!!!
      For energy I drink one Monster Engery Lo Carb drink each morning.
      No worries I haven’t turned into some kind of health boy I just got tired of coffee for some reason.

        Regarding Monsters

        by tink! ·

        In reply to Teeth

        The guys in the plant here have been on a Monster kick. One guy though, went overboard one Sunday. He had like 6 of the regular size cans during the afternoon and then went and got 2 jumbo cans and downed them both in less than an hour.

        He said the next morning it took him a while to remember some of the previous evening. It was as if he’d be flat-out drunk, but without the hang-over.

        If you look into the active ingredients you’ll see that the B vitamins can be somewhat beneficial, but also harmful in excess [i](any harm done is reversible once supplementing has stopped)[/i] The main active ingredient is Caffeine. Guarana is also basically caffeine. Taurine is an amino acid that does nothing really. Ginseng can help a bit. And I think there is one other ingredient that starts with a “Cit” that can possibly be contributed to muscle build-up.

        But basically, energy drinks are caffeine with a little extra stuff.

          Oh yeah!!!

          by ben “iron” damper ·

          In reply to Regarding Monsters

          I’ve read the cans and I agree. But I needed some substitute for coffee since it was making my teeth so darn gross looking.
          That and I only drink one regular can per day and that’s it!! So I figure I get the caffeine boost plus a vitamin or two and that’s it for the day.
          But yes like most anything too much can be a bad thing!

      • #3283106

        by w2ktechman ·

        In reply to Teeth

        a 6 pack of Mountain Dew before Lunch, along with the daily Monster. But the doc said I had to stop completely. Even 3 weeks later I was having withdrawls and in a not-so-good mood.
        Finally I started drinking coffee with Splenda instead.

      In reply to Is Coffee bad for you? Depends on your genetics

      After a cup or two of coffee, I am ready to go.

      I get three or four, I am ready for a nap.

      Back during my only addiction I ever had, it was to caffeine. I went through two 8packs of Mountain Dew a day, everyday. I could not sleep if I didn’t drink a bottle of Dew right before laying down. This was back when I was in the early 20’s working two jobs, one first shift and one third shirt. Twice a week I pulled a 36 hour shift between the two jobs.

          Oh yeah, as for my Mountain Dew addiction, I am completely cured. After the EX had the affair with her pepsi merchandiser, I lost any and all desire to ever buy another pepsi product again. Mine is now a coke household. C2 and the ZERO’s are actually pretty good too! B-)

        I would wake up in the middle of the night needing a mt. Dew fix. 15 min. after drinking a can, I was again, ready for bed.

          We are talking glass bottles here baby!

          This is back when soda was sooooo good!

          Faygo now offers their in glass bottles, just depends on where you go. The reaction of the acid and the metal or plastic just ruin it. That and it never seems to get as cold in the plastic either.

          All pepsi products are horrible in the can.

          I also now find I no longer have any desire to purchase any of their products ever since one of their merchandisers used his position to have an affair with me EX, causing the breakup of the marriage. Thanks Pepsi! So long!

          The good news is I no longer drink the 220 cals per serving with 2.5 servings per container, giving 550 cals per bottle! I don’t miss that at all!

          Good buy Pepsi, hello Coke! 😀 (C2 and coke zero are actually good, for diet soda!)

          I agree Pepsi and Diet Pepsi in cans especially are horrible. I’ve never liked Diet Dew either. But a friend at work told me that they “re-did” the formula of Diet Dew and to give it a try, I did and boy was he right, it’s great!!!
          So my two favorite diet drinks are Diet Dew and Diet Dr. Pepper.

        only with those long pretzel rods. Adding sodium is another factor to the issue, along with a pack of marlboros a day. as far as coffee goes, this is the drink of choice around my house, in the form of a 34 oz.can every week between my wife and me, and my other choice for dinner is red top (whole) milk which i do about 3 gallons a week.

      In reply to Is Coffee bad for you? Depends on your genetics

      I used to drink 2 pots of coffee a day until I retired from the military. Was diagnosed as pre-hypertensive, and had all the recommendations on how to reduce BP without drugs. So almost all of the salt disappeared, and I’m down to 2 cups of caffinated coffee a day max. Now if I can drop the extra 20 pounds I’m carrying, I ought to be able to have a normal BP without any drugs at all.
