Many people believe that java, not unlike junk or meat make immune system weak. That belief persists despite studies showing the opposite.
Coffee is one of those “addictive substances” associated with poor lifestyle habits such as smoking and drinking. It is a beverage associated with habits that ruin health, so it should not be be good for the immune system, right?
Does coffee and low immune system go together?
Many internet “experts” hang on to an idea that coffee, because it accompanies other “bad” habits, must be also bad for you. They spread the notion that the beverage causes health problems and lowers body defenses thus you should be immediately parting with that health-robbing beverage. Not surprisingly, quitting coffee for health reasons became a popular trend.
While browsing for anti-java messages I found these outdated claims:
- “coffee suppresses immunity”,
- “boosted energy is not the result of the beverage itself but the immune system’s effort to get rid of it”,
- “it weakens defenses by robbing you of minerals” or even a bigger circulating scare
- “you will get pancreatic cancer when you drink it”.
Searching for answers about causes of low immune system can have your head spinning. So what is the bottom line? Is coffee lowering or boosting the immune system? Should you drink or quit it? We all know that strong immune system protects against cancers, so let’s have a look at the studies, not opinions. In the meantime I would like to interest you in what weak immune system is and a few tips on how to boost it. Here are some interesting articles:

A large cohort study involving 85,000 women over 22 year span examined a relationship between coffee, tea, caffeine and breast cancer risk. It established that neither caffeinated nor non-caffeinated coffee/tea drinking habit was associated with an increased risk for breast cancer. In fact, data suggested an inverse relationship between consumption of these beverages and the post-menopausal breast cancer risk . What’s more, a very significant breast cancer protection effect was found in those women who drank over four cups a day. research. I would celebrate that with a cup of great organic espresso!
Colon / liver cancer
Having that shot in the morning apparently protects against colon and liver cancers. Kaweol and cafestol are two already identified substances in coffee that inhibit mutagenicity and tumogrenicity of several carcinogens. This one particular study on rats confirmed that it substantially improves protection against xenobiotics. research
Oral, esophageal, pharyngeal cancer
This European study examined 1144 cancer patients and 2840 controls. The study identified a clear and substantial correlation between heavy coffee drinking and increased protection against these cancers. Subjects who drank the most (over three cups a day) were the most protected, provided they used caffeinated form. Non-caffeinated beverages did not seem to give any protection. research
Coffee has been reported to lower levels of estrogen and insulin, two hormones implicated in endometrial carcinogenesis. This study observed coffee drinking habits of 67,000 participants and their correlation to endometrial cancer risk. The correlation between the beverage and endometrial cancer was significant. Women who drank over four cups a day were the most protected. Those who drank tea did not benefit from cancer protection. research
A recently updated meta-analysis of 16 previous studies has found coffee to be protective both against liver cancer as well as liver cirrhosis. The inverse relationship between coffee and hepatocellular carcinoma risk was consistent regardless of the subjects’ sex, alcohol drinking, or history of hepatitis or liver disease. The anti-cancer effect was higher with increased coffee consumption. research
5035 men with prostate cancer including 642 metastatic prostate cancer cases were compared to 48,000 “healthy” men. Men who consumed six or more cups of caffeinated and non-caffeinated coffee per day had a lower adjusted relative risk for overall prostate cancer compared with non-drinkers. The effect was especially pronounced for those with lethal metastatic prostate cancer. The cancer protection effect seemed to be pointing out to non-caffeinated constituents of coffee. research
Can coffee be cancer-causing?
There is still some internet anti-coffee “experts” quoting earlier studies suggesting a possible link between pancreatic cancer and java consumption. However the most recent comprehensive meta-analysis did not find any link between the beverage and pancreatic cancer even with high intakes. Similar finding were reported in regards to gastric cancer. research 1 research 2
59 studies consisting of 40 independent cohorts examined relationship between coffee drinking habit and cancer risk. An increase in consumption of one cup of coffee per day was associated with a 3% reduced risk of all cancers. Specifically, coffee drinking was associated with a reduced risk of bladder, breast, oral, pharyngeal, colorectal, endometrial, esophageal, hepatocellular, leukemic, pancreatic, and prostate cancers. research.
Taking these numbers into consideration it does not look like the beverage contributes in any way to low immune system. It is also worth noting that high antioxidant foods are powerful cancer fighters and the espresso method of extraction yields the highest antioxidant activity out of all brewing methods.
However, some other studies found a substance with suspected anti-carcinogenic effect. Its name is methylpyridinium. This compound is rather unique to java plant and is not common in other foods. However, it is worth mentioning that methylpyridinium is not present in raw coffee beans but is formed during the roasting process. It can be found in both caffeinated and decaffeinated beverages.
