Coffee is the most popular drink in the world. Not only does it taste delicious, attractive, and not a drink, coffee also has many health benefits for users. A new system review and meta-analysis including the latest research published in the journal BMJ Open, found a clear positive correlation between high coffee consumption and a lower risk of prostate cancer. Prostate cancer is the second most common cancer and the sixth most common cause of cancer death in men.
In the United States alone, more than half of the population drinks at least one cup of coffee a day. Therefore, it is not surprising that scientists have focused quite a lot on the health effects of this popular beverage.
There have been studies showing that coffee supports obesity, anti-aging, protects against Parkinson’s disease and helps a healthy heart. Besides, there are also studies showing that coffee has the ability to cause cancer, leading to a battle between two streams of opinion in 2018 in the US state of California about whether a cup of coffee should be labeled with a scene. report cancer or not.

Besides general observational studies showing that drinking coffee can have beneficial effects, recent large meta-studies have shown no difference in cancer risk between people. drink coffee with people who don’t.
Coffee consumption is linked to a reduced risk of liver, bowel and breast cancers, but there is no conclusive evidence of its potential role in reducing the risk of prostate cancer. To better understand this issue, the researchers reviewed the research databases for the relevant cohort published through September 2020.
Although data has been shown to be inconsistent on whether lower prostate cancer rates are associated with higher coffee consumption, this study begins a new meta-analysis. includes the latest and most up to date published studies. 16 studies were pooled for analysis, with more than 1 million subjects and 57,000 prostate cancer cases.
Researchers have uncovered a distinct linear trend that links increased coffee consumption with a reduced risk of prostate cancer. “In dose response analysis, we observed a nearly 1% reduction in prostate cancer risk for one cup of coffee per day,” they wrote.
Researchers hypothesize several potential mechanisms to explain how coffee can reduce a person’s risk of prostate cancer: “Coffee improves glucose metabolism, reduces plasma insulin concentrations and insulin-like growth factor-1, has anti-inflammatory and antioxidant effects, influences sex hormone levels, all of them. May play a role in reducing cancer risk Prostate“.
A 2019 study magnified the effects on prostate cancer of two special anti-cancer compounds found in coffee. In mouse models of prostate cancer, kahweol acetate and cafestol seemed to work together to inhibit cancer cell growth.
These types of large meta-analyzes cannot provide a definitive answer. The researchers admit that their conclusions should be “interpreted with caution” due to the significant heterogeneity of the studies being analyzed. No one is suggesting men increase their coffee consumption as a way to protect themselves from prostate cancer, but at least those with prostate cancer concerns can enjoy their favorite cup of coffee. their days without worrying too much.
