Drinking more coffee can reduce the incidence of coffee health knowledge

Researchers from Harvard analyzed it based on a long-term follow-up study funded by NIH. The study involved 50000 men who, among other factors, recorded their long-term coffee intake over a 20-year period from 2006 to 2006. the amount of coffee each person drank every four years and the risk of prostate cancer.

It turns out that men who drink more than six cups of coffee a day are 60% less likely to develop any terminal cancer than those who never drink coffee. Those who consumed four to five cups of coffee a day reduced their risk of prostate cancer by 25 percent, while those who consumed three cups reduced their risk by 20 percent.

Overall, coffee drinking is more likely to be associated with a reduced risk of prostate cancer, but the extent of the effect is not statistically significant. Of course, this form of epidemiological study does not clearly prove a causal relationship between drinking coffee and reducing prostate cancer, but men drinking too much coffee may have a preventive effect, making them less likely to develop prostate cancer.

However, the lead author, Katherine Wilson, a postdoctoral fellow at Harvard University, says there is reason to believe there may be a causal relationship between the two. There is already evidence that "coffee has an effect on insulin and glucose metabolism, as well as sex hormone levels, all of which play a role in the development of prostate cancer," she said in a statement. "the relationship between coffee drinking and prostate cancer is credible."

This study is the first to find a relationship between coffee drinking and prostate cancer, which is inconsistent with previous studies, and no such association has been found in the past. This work is still preliminary, and more work needs to be done to determine whether drinking coffee is a convenient and effective measure to prevent prostate cancer. "until the truth is further discovered, people should not start to change their coffee drinking habits and coffee consumption," Wilson said. The findings were presented at a recent meeting of the American Association for Cancer Research in Houston.
