A new review study suggests that drinking several cups of coffee a day could reduce a man’s risk of prostate cancer.
Coffee consumption has already been linked to a lower relative risk of a number of different forms of cancer, such as liver, bowel, and breast cancer. At present, though, there is no conclusive evidence for its potential role in reducing the risk of prostate cancer.
Each additional daily cup of was associated with a reduction in relative risk of nearly 1%, the findings, published in the online journal BMJ Open, indicate. The study was a review of 16 research papers published up to September 2020, and comprised over a million male research subjects, of whom nearly 60,000 developed prostate cancer.
Prostate cancer is the second most common cancer, and the sixth leading cause of cancer death in men. Nearly three out of four cases occur in the developed world, and since the 1970s, new cases of the disease have risen sharply in Asian countries, including Japan, Singapore, and China.
The researchers suggest a particular biological mechanism that might explain why coffee consumption is associated with lowered prostate cancer risk.
The researchers point out that coffee improves the body’s metabolism of glucose, has potent anti-inflammatory and antioxidant effects, and affects sex hormone levels. All of these factors may influence the onset, development and progression of prostate cancer.
We’ve already reported on coffee’s testosterone- and metabolism-boosting effects in a number of articles.
For instance, coffee drinkers were found to have more testosterone and less estradiol than non-drinkers, in a Harvard University study.
The benefits didn’t stop there, either. The researchers also looked at the ‘good fat hormone’ adiponectin and the inflammatory factor CRP, and found similarly positive effects. In the blood of the study participants who drank 4 cups or more of coffee per day, they found 16.6 percent less CRP and 9.3 percent more adiponectin.
The Harvard researchers identified that it wasn’t the caffeine but the polyphenols, and especially probably chlorogenic acid, that were having these beneficial effects. That’s good news for insomniacs and those who worry about coffee’s effects on their sleep patterns: you can drink decaff and still expect the same beneficial effects.
Sleep is an absolutely vital aspect of training and recovery, one that receives less attention than it should, and we know that many are wary of coffee because of its potential to disrupt sleep. Improving your sleep can DOUBLE your testosterone levels. Yes, that’s right: DOUBLE your testosterone levels.
Caffeine is also a potent pre-workout which can prime your body for fat loss.
A new study from the University of Granada shows drinking a strong cup of coffee (the equivalent of 3mg/kg bodyweight) half an hour before working out has a significant effect on fat burning. The researchers also discovered that the effects were more pronounced if the workout – and the caffeine consumption – took place during the afternoon rather than the morning.
Returning to the present study under consideration, the researchers conclude: “This study suggests 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.”
