Israeli Study: Caffeine Makes Genetic Material Age

7

sodaCaffeine makes the genetic material in the cells grow older, researchers from Tel Aviv University have discovered.

For years we thought coffee was bad for our health. Then, new studies found that a few cups of coffee a day can actually be pretty healthy. Now, Israeli researchers have discovered that caffeine and alcohol affect the cells’ ageing, the genome’s stability, and even the chance of getting cancer.

The study was conducted by Prof. Prof. Martin Kupiec, Dr. Gal Hagit Romano, Yaniv Harari, Dr. Assaf Gottlieb and other researchers, and was published recently in the PLoS Genetics journal.

The researchers based their study on the finding that stress shortens telomeres – the ends of the chromosomes, which protect the genetic material in each cell. The telomeres serve as the cell’s “biological clock” and become shorter as the cell grows older.

“We found out that substances we are exposed to in our daily life – especially caffeine and alcohol – affected the length of the telomeres,” explained Dr. Gal Hagit Romano.

“We found that a low concentration of caffeine (for example like in a regular shot of espresso) significantly shortened the telomeres. A low concentration of alcohol (5% and 7%), however, elongated them significantly,” she added.

Cancer cells actively lengthen the cell’s telomeres, so that they can continue dividing forever.

  1. This is sensationalism and not science. I have not seen the original study but I am sure that they were not done on people but on either isolated cells or lab animals.

  2. “For years we thought coffee was bad for our health. Then, new studies found that a few cups of coffee a day can actually be pretty healthy.”

    “Now, Israeli researchers have discovered that caffeine and alcohol affect the cells’ ageing, the genome’s stability, and even the chance of getting cancer.”

    Can someone explain the contradictory sentences in one paragraph?

  3. To #3- explanation:
    First we all thougt it was bad. Then we were told it is good. Now they’re saying it’s bad again. End of explanation.

  4. Junk science. It’s good, it’s bad. It’s always about money, nothing else. On the contrary, coffee is healthy, but as with everything, in moderation. When someone drinks a dozen cups per day, of course, it might even be dangerous, but a few, at the most, per day is probably quite healthy. Maybe, this is the way, they can start taxing it, who knows? There’s always a reason and that’s money/power.
