According to one study, “increased” coffee consumption may be linked to a reduced risk of prostate cancer.
The researchers found that higher coffee consumption was significantly linked to a decreased risk of prostate cancer.
In the new study, published in the journal BMJ Open, researchers examined data from 16 different studies.
They pooled the information to assess the overall reduction in the risk of coffee consumption.
The team at Shengjing Hospital at China Medical University found that men who drink several cups of coffee a day have a lower risk of developing prostate cancer than men with the “lowest” consumption.
Each additional daily cup was associated with a 1% risk reduction, the results show.
The studies included in the analysis examined data from more than one million men in North America, Europe, and Japan.
The data included information on nearly 58,000 men with prostate cancer.
Compared to the lowest category of coffee consumption, the risk of prostate cancer appeared to have decreased by 9% for those considered “most consumed”.
Another analysis found that the highest intake was associated with a 7% lower risk of localized prostate cancer compared to the lowest intake
The researchers saw a 12% lower risk of advanced prostate cancer.
And a 16% reduction in the risk of death for prostate cancer in those who drank the highest amounts compared to those who drank the lowest amounts.
The authors point out that coffee improves glucose metabolism, has anti-inflammatory and antioxidant effects, and affects sex hormone levels, which can affect the initiation, development, and progression of prostate cancer.
The authors indicated that due to the observational nature of the research and the fact that most coffee consumption data was based on the recall when the participant was recalled and therefore possibly misinterpreted, the results should be interpreted with caution.
However, they conclude: “This study suggests that increased coffee consumption may be linked to a reduced risk of prostate cancer. More research is still needed to examine the underlying mechanisms and agents 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 their risk of prostate cancer.”
