coffee beans, coffee do you need

Should you have another cup of coffee? Previous studies have suggested that coffee drinkers might live longer. But how much coffee do you need to drink for this benefit?

How Many Cups of Coffee Do You Need to Live Longer?

New data presented at the European Society for Cardiology meetings seem to confirm that coffee drinkers are less likely to die prematurely. The investigators wanted to see if the previously-reported longevity benefits of coffee would hold up for people following a Mediterranean diet and lifestyle.

The volunteers in this study were approximately 20,000 adults who graduated from the University of Navarra in Spain, starting in 1999. Their average age at recruitment was 37.

Four Cups of Coffee a Day Seems to Help:

Ten years of follow-up revealed that those who drank at least four cups of coffee daily were about 64 percent less likely to die during that time than those who never touched the stuff. Such young people don’t die very often, however, so the absolute risk of premature death for people who don’t like coffee is probably still very small.

The investigators report that the benefits are clearest for people who are at least 45 years old. In fact, for every additional two cups of coffee the older volunteers drank, the risk of dying during the study dropped by 30 percent.

Dr. Adela Navarro, the cardiologist who led the study, remarked:

“Our findings suggest that drinking four cups of coffee each day can be part of a healthy diet in healthy people.”

    My mother and mother-in-law both drank coffee and both lost 4 inches in height. My 5’9″ sister has consumed coffee since she was a teenager and is now down to 5’4″. I don’t drink coffee, but consume mostly herb tea as well as decaf tea. I have lost 1-1/2 inches in height. That’s not great, but it’s better than 4 inches.

    Is coffee safe for those with hypertension or the concern is not addressed in this study? I have not been able to find any article that is conclusive stating coffeee is not safe for those with hypertension.

    Well, how about those with hypertension and AFB. Would coffee have a side effect on those conditions or as long as 4 cups a day, it is safe to drink it.
    The existing literature about coffee consumption and hypertension is not conclusive. What is the expert view on this issue?

  4. MFK

    It would be helpful to clarify what “a cup” actually means. How many ounces does this refer to? And what strength? If a person drinks strong coffee, does this reduce the total consumption in ounces that is needed for positive effects? Thanks.

    What constitutes a cup?

  6. Hank

    It might be useful to know who paid for this study?

    • Terry Graedon

      Yes, Hank. This was a government-funded study:
      Sources of funding: The SUN Project is funded by the Instituto de Salud Carlos III, the CIBER, and the Regional Government of Navarra.
      The authors declared no conflicts of interest.

  7. Cynthia

    Could they define what a cup is? Is it 6oz, 8 oz, any ideas?

    • Terry Graedon

      In Spain, and probably in Europe generally, a cup of coffee is 6 oz. A cup of espresso also counts, though it is much less volume.

  8. Dianne

    Were any adverse effects noted?

  9. Sara

    I should qualify….

  10. Shirley

    In the study on coffee adding to longevity…Does it matter whether it’s de-caf or regular coffee? I drink a lot of decaf and worry if I drank that much regular I would never get to sleep.

    I believe that there is ‘salt’ and then there is ‘salt.’ Some kinds of salt sticks with me–and plain table salt is why I don’t eat salt. Ham and sausage’s salt is worst for me. Even if I eat a modest amount of ham or sausage, the salt and swollen legs take about 3 days to get rid of. No less than 3 full days. Either it is a different kind of salt or they use a great amount, I’m not sure which. Maybe both.

    Doesn’t coffee contribute to pancreatic cancer?

  13. Laura Etten

    Do you still have protection from decaffeinated coffee?

  14. David

    In the study Dr. Navarro makes no mention is made of the “type” coffee, i.e. decaf or caffeinated. This seems like very pertinent information as regards study design.

  15. John

    Well, among coffee producers, manufacturers of coffeemakers (especially frustrating) and even coffee recipes, there is no agreement on what a “cup” is, as a form of measurement, this article leaves a lot to be desired, especially if there is an upper limit where the “benefits” become detrimental.

  16. Mare

    Are coffees the same in respect to this article, or are organics any better; how about flavored coffees, decaf ? Anyone done any actual studies on what coffees appear to work for health?
