Coffee or Tea Keeps Diabetes Away….

May 11, 2010

Anothe rgood news for coffee lovers like me… Now comes a new study agina showing the reduction in ones risk to develop diabetes.  The study was recently published in the Archives of Internal Medicine December issue


Background  Coffee consumption has been reported to be inversely associated with risk of type 2 diabetes mellitus. Similar associations have also been reported for decaffeinated coffee and tea. We report herein the findings of meta-analyses for the association between coffee, decaffeinated coffee, and tea consumption with risk of diabetes. Methods  Relevant studies were identified through search engines using a combined text word and MeSH (Medical Subject Headings) search strategy. Prospective studies that reported an estimate of the association between coffee, decaffeinated coffee, or tea with incident diabetes between 1966 and July 2009.

Results  Data from 18 studies with information on 457 922 participants reported on the association between coffee consumption and diabetes. Six (N = 225 516) and 7 studies (N = 286 701) also reported estimates of the association between decaffeinated coffee and tea with diabetes, respectively. We found an inverse log-linear relationship between coffee consumption and subsequent risk of diabetes such that every additional cup of coffee consumed in a day was associated with a 7% reduction in the excess risk of diabetes relative risk, 0.93 [95% confidence interval, 0.91-0.95]) after adjustment for potential confounders.

Conclusions  Owing to the presence of small-study bias, our results may represent an overestimate of the true magnitude of the association. Similar significant and inverse associations were observed with decaffeinated coffee and tea and risk of incident diabetes. High intakes of coffee, decaffeinated coffee, and tea are associated with reduced risk of diabetes. The putative protective effects of these beverages warrant further investigation in randomized trials.


This study again shows same conclusion as in the past that a mere 4 cups of coffee per day whether regular or decaf has been shown to reduce ones risk to develop diabetes by 27%.  And what is interesting is that for every extra cup of coffee, an additional 7 % further reduction is risk to develop diabetes was noted.

The study therefore points out to one thing…that caffeine may not be the factor as decaf can result in similar reduction in risk.  Other chemicals present in coffee therefore need to be explored…. 

However…one should not resort to just relying on coffee to reduce our risk to develop diabetes.  We have to remember that lifestyle and proper food intake has been shown to reduce the risk of developing diabetes by a whoooping 50%….

There you go guys…enjoy our coffee!!!!

    regular coffee is not much different from decaf in reducing diabetes, but is Starbucks coffe better than Nescafe?

    I have read of one study that showed a decreased incidence of Parkinson’s disease and coffee consumption. The real question is what is in the coffee that makes people healthy? Is it the caffeine or the antioxidants, or both?
    For the most part, I think caffeine got a bad rap from the almighty popular media and food manufacturers. Look at what happened to lactose. Just because a few people got a little bloating after dairy consumption, lactose became the new popular poison. Food manufacturers quickly jumped into the bandwagon and manufactured and advertised. everything as lactose free.
    The new “poison” that food manufacturers are claiming they are totally free off is “gluten”. I don’t know the exact figures, but surely only a small percentage of the population really need to be on a gluten free diet, yet everything out there has this label “GLUTEN FREE’. Now thanks to unscrupulous food manufacturers, people believe beyond a shadow of a doubt that gluten free is healthy and that food with gluten have got to be bad for you.

    What’s interesting, is that Americans are the people who hold fast to this more than anyone else.

    First it was Caffeine, then lactose, now gluten. I invite anyone to make a guess as to what the next “popular poison” might be.

      Gluten is not a poison, it is a protein found mainly in wheat. People that require gluten free products have an allergy/hyper-sensitivity to wheat/gluten.Gluten is also found in other grains as well. If people that are gluten sensitive continue to consume gluten, it can cause all types of serious medical problems including nausea and vomiting after meals, which in children results in failure to develop at a normal rate due to the lack of nutritional intake that can be absorbed by the intestines (which become inflammed due to the gluten). Later in life it can lead to cancers of the intestines and stomach. It is a very serious food allergy, that is why the labeling is more noticeable now. Try raising a kid that can never have bread. Most processed foods that kids love also contain wheat fillers, it is very difficult. Around 1-3 people per 100 are afflicted with this disease, with many never getting diagnosed. i hope food manufacturers aren’t using the labeling to boost sales, but it is better than having more sick kids and adults with cancers. Make sure you do your research before posting about “gluten free” products.

    So true – I guess it will be something else next week that will be so good or so bad for us.

    But interesting stuff about the coffee/diabetes connection. I know a few people that would just love to use this study as an excuse to drink even more coffee!

    As always, thanks for the article. Very interesting.

    I am weary of all studies that make claims that in a decade or so will be reversed once they get more data from people who were convinced that more of something is better for you. I think you have to be cautious. I also think that David made Mari’s point. Only 1 – 3 % of people have gluten allergies, while it is serious for those who have it, it isn’t epidemic. I also think that the factor that you really can’t loose site of is genetics, which is why someone has allergies, or predisposed to diabetes. My fiance was diagnosed with type 2 diabetes three years ago, he has it on both sides of his family and one of his half brothers has it too. So, all you can do is don’t overindulge and know what your families health history is, it could assist in making good choices.
