It is well known that coffee has more health benefits than disadvantages for the human body. It has been shown to reduce the risk of Parkinson’s, protect against dementia and have a positive influence on the liver and blood sugar level. A new data analysis now suggests that daily coffee consumption could also lead to a lower risk of developing prostate cancer.
Prostate cancer is the most common cancer among men in Germany. The Berlin Robert Koch Institute (RKI) counts around 67,000 new cases per year. Detected in good time, prostate cancer is easily treatable and not life-threatening. Nevertheless, according to the German Society for Men and Health eV (DGMG), around 12,000 to 14,000 men die of prostate cancer every year. A meta-analysis now suggests that drinking coffee every day could prevent prostate cancer: every cup drunk could reduce the relative risk by almost one percent.
For the published in the specialist magazine “BMJ” Data analysis scientists summarized 16 studies from North America, Europe and Japan. They each examined the influence of daily coffee consumption on prostate cancer. In total, more than a million men (1,081,586) took part, 57,732 of whom had prostate cancer.
Just two cups of coffee a day could reduce the risk of prostate cancer
The meta-analysis showed that men who stated that they drank two to nine cups of coffee a day had a nine percent lower risk Prostate cancer to get sick compared to men who drank no to a maximum of two cups of coffee a day. Each additional cup of coffee drunk seemed to reduce the relative risk by an additional percent.
A refined analysis of study participants already suffering from prostate cancer suggested that high daily coffee consumption could be associated with a 12 to 16 percent lower risk of advanced and fatal prostate cancer than no to low coffee consumption.
Why is coffee so effective for prostate cancer?
The scientists write that the results can be traced back to plausible biological explanations. Because coffee improves the glucose metabolism in the body. In addition, the substances it contains have anti-inflammatory and antioxidant effects. And they would affect sex hormone levels, which can affect the initiation, development, and progression of prostate cancer.
“This meta-analysis suggests that increased coffee consumption may be linked to a reduced risk of prostate cancer,” explains the research team. More research is needed to examine the underlying mechanisms and active ingredients in coffee. “If the link is found to have a causal effect, men could be encouraged to increase their coffee consumption in order to potentially reduce the risk of prostate cancer.”

How representative is the data analysis of the studies?
How much coffee the test subjects actually drank every day cannot be checked, as this was a self-assessment of the study participants. In addition, since this is a meta-analysis from various studies, the results may be biased. Accordingly, further studies are necessary to further research the positive influence of coffee on the risk of prostate cancer and, if necessary, to scientifically prove it.
