A systematic review and meta-analysis published in the BMJ in January 2021 suggests a link between coffee consumption and a lowered risk of prostate cancer.
The study concluded that, "increased coffee consumption may be associated with a reduced risk of prostate cancer. Further research is still warranted to explore the underlying mechanisms and active compounds in coffee.
"If the association is further proved to be a causal effect, men might be encouraged to increase their coffee consumption to potentially decrease the risk of prostate cancer."
