High consumption of coffee can reduce the risk of prostate cancer
A study published online in BMJ Open assures that drinking several cups of coffee a day may be linked to a lower risk of developing prostate cancer.
What if drinking your morning coffee was also a healthy gesture? In any case, this is what a recent study published in the online journal BMJ Open suggests. According to this research, drinking several cups of coffee a day could be linked to a lower risk of developing prostate cancer. Specifically, each additional daily cup was associated with a relative risk reduction of nearly 1%.
Previous studies have already established a lower risk of liver, bowel and breast cancer based on coffee consumption. Prostate cancer is more common in men, its 5-year net survival rate is over 90%.
For this study, the researchers searched research databases and pooled numerous studies. The included studies were conducted in North America (7), Europe (7), and Japan (2). They included more than one million men (1,081,586) of whom 57,732 developed prostate cancer. The highest level of consumption ranged from 2 to 9 cups or more per day, the lowest level ranged from nothing to less than 2 cups per day.
Compared to the lowest category of coffee consumption, the category with the highest coffee consumption was associated with a 9% reduction in the risk of prostate cancer. And each additional daily cup was associated with a 1% risk reduction. Additionally, higher intakes were associated with a 7% lower risk of localized prostate cancer and a 12-16% lower risk of advanced and fatal prostate cancer.
Anti-inflammatory and antioxidant effects.
However, the researchers note that certain factors were not taken into account, which could distort the risk estimate. In addition, the type of coffee and the methods of preparation vary according to the studies. But the scientists point out that there are many biological explanations that can validate these findings. In fact, the authors claim that coffee improves glucose metabolism, has anti-inflammatory and antioxidant effects. It also affects the levels of sex hormones, which can influence the development and progression of prostate cancer.
This study suggests that increased coffee consumption may be associated with a reduced risk of prostate cancer. "More research is still needed to explore the underlying mechanisms and active compounds in coffee." "In addition, shown to be a causal effect, men could be encouraged to increase their coffee consumption to potentially reduce the risk of prostate cancer," the authors of this study conclude.
