Coffee Might Help Ward Off Prostate Cancer
TUESDAY, JAN. 12, 2021 — A cup of java may not be a bad idea for men’s health: Drinking lots of coffee may reduce their risk of prostate cancer, researchers report.
The investigators analyzed data from 16 studies conducted around the world. Together, the studies involved more than a million men, about 58,000 of who went on to develop prostate cancer. The team was led by urologist Dr. Kefeng Wang, of China Medical University in Shenyang.
Their analysis couldn’t prove cause-and-effect, but compared to men with the lowest coffee consumption, those who drank the most coffee had a 9% lower risk of prostate cancer.
As well, each additional daily cup of coffee was associated with a 1% reduction in risk, according to the research published online Jan. 11 in the journal BMJ Open.
Further analysis showed that compared to those with the lowest consumption, men who drank the most coffee had a 7% lower risk of localized prostate cancer, and a 12% to 16% lower risk of advanced and fatal prostate cancer, respectively.
The highest amounts of coffee consumption ranged from two to nine or more cups a day, while the lowest ranged from none to fewer than 2 cups a day.
The researchers said their findings do need to be interpreted with caution because unmeasured or uncontrolled factors in the observational studies could have affected the overall prostate cancer risk estimate.
Still, Vigneri believes that moderate coffee intake probably isn’t a bad thing.

Over 1 Million Participants
Two researchers independently reviewed the relevant literature that is available. After discussing their reviews, they decided to include 16 studies in their meta-analysis. The studies collectively involved 1,081,586 men. Of them, 57,732 developed prostate cancer.
In the studies, the participants self-reported their coffee consumption. As many as 15 of the studies compared the highest level of coffee consumption with the lowest level.
However, the amount of coffee consumption these categories represented varied from two to nine cups for the highest category, to none to one for the lowest.
After analyzing the data across the studies, the researchers found that the highest category of coffee consumption was associated with a 9% decrease in the risk of prostate cancer when compared with the lowest category.
Each single cup of coffee was associated with a 1% decrease in prostate cancer risk.
More specifically, the researchers found that localized prostate cancer cancer that has not spread to another part of a persons body was 7% less likely to develop in the highest category of coffee consumption compared with the lowest.
For advanced prostate cancer, the highest category of coffee consumption was associated with a 12% reduction in risk compared with the lowest. For fatal prostate cancer, the highest category was associated with a 16% reduction in risk compared with the lowest.
Dr. Kefeng Wang, of China Medical University in Shenyang, and his co-authors explain:
Coffees Many Health Benefits May Reveal The Connection
Dr. Wangs team notes that this may cause some of the results to be skewed depending on the location. The biggest limitation on the data comes from studies using observational data which relies on participants giving accurate figures on their coffee consumption. The results also dont take into account the types of coffee or their brewing methods.
That said, researchers point out there is a biological explanation for their findings. Coffee is known to improve blood sugar levels and has anti-inflammatory and antioxidant benefits. It also affects sex hormone levels, all of which could help protect against prostate cancer.
Further research is still warranted to explore the underlying mechanisms and active compounds in coffee, Dr. Wang and the team conclude. 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.
The ACS estimates that over 34,000 men in the United States will die of prostate cancer in 2021. Nearly a quarter-million will be diagnosed with the disease.
The findings appear in the British Medical Journals BMJ Open.

Coffee And Prostate Cancer: The Study
According to a study carried out by the Harvard School of Public Health and published on May 17, 2011, men who regularly drink coffee have a lower incidence of prostate cancer.
This study was born from the desire to investigate some of the beneficial effects of the drink that act as antioxidants, therefore reducing inflammation and regulating insulin: factors that can affect prostate cancer.
It is no coincidence that coffee consumption was also previously associated with a lower risk of getting Parkinsons, type 2 diabetes, gallstones, liver cancer, or cirrhosis.
During the research, a sample of 47,911 US men was examined, who said they drank coffee every 4 years between 1986 and 2008. During this period, 5,035 cases of prostate cancer were reported, including 642 fatal or metastatic cases.
Interesting data that have led scholars to draw some important connections.
In particular, it was found that men who drank 6 or more cupsof coffee each day had a 20% lower risk of contracting prostate cancer than people who did not drink it.
Scientists have reported that 1 to 3 cups a dayis enough to reduce the chances of getting aggressive prostate cancer by nearly 1/3. Also, 4 or more cups can help delay tumor progression in sick patients.
The beneficial effects of coffee, as we have already mentioned, however, must be combined with a healthy and correct lifestyle. Smoking should be avoided, and healthy physical activity practiced.
Coffee May Keep Prostate Cancer Recurrence And Progression Away
SEATTLE â Aug. 26, 2013 â Coffee consumption is associated with a lower risk of prostate cancer recurrence and progression, according to a new study by Fred Hutchinson Cancer Research Center scientists that is online ahead of print in Cancer Causes & Control.
Corresponding author , co-director of the Program in Prostate Cancer Research in the Fred Hutch Public Health Sciences Division, conducted the study to determine whether the bioactive compounds in coffee and tea may prevent prostate cancer recurrence and delay progression of the disease.
Stanford and colleagues found that men who drank four or more cups of coffee per day experienced a 59 percent reduced risk of prostate cancer recurrence and/or progression as compared to those who drank only one or fewer cups per week.
They did not, however, find an association between coffee drinking and reduced mortality from prostate cancer, although the study included too few men who died of prostate cancer to address that issue separately.
First study to assess the link between tea and prostate cancer outcomes
Regarding tea consumption, the researchers did not find an associated reduction of prostate cancer recurrence and/or progression. The study also did not draw any conclusions regarding the impact of tea drinking on prostate-specific death.
Phytochemicals in coffee have anti-inflammatory and antioxidant effects
Additional studies needed to confirm whether coffee can prevent cancer recurrence

Best Foods For Prostate Health
We dont often think about the best foods for our prostate health. If it smells right and tastes good, its okay to eat.
However, studies have shown that lifestyle and diet play an enormous role in mens healthparticularly prostate health. Eating the rights foods is extremely beneficial to have a healthy prostate.
Regrettably, unhealthy foods are very present in the majority of everyday diets.
Large amounts of processed food, salty foods, and junk food are the norm.
These are bad for health generally, but especially for prostate health. They only increase the likelihood of developing prostate diseases and becoming obese.
Interestingly, the diet recommendations by leading health organizations around the world are the Paleo/Ketogenic diet. Fish, seafood, fresh fruit and vegetables, nuts, and healthy oils.
All of these are in the Paleo diet. If youre suffering from prostate issues, we highly recommend you check out the Paleo/Ketogenic diet. It is the best diet for fighting prostate disease, getting fitter, and losing weight.
Below we list 10 of the best foods that will help improve, support, and sustain prostate health.
Tips For Cutting Back On Caffeine
Kicking caffeine to the curb may help your BPH symptoms, but doing so can be challenging. Caffeine is a stimulant, and its often addictive. Learn more about the effects of caffeine on the body.
- difficulty concentrating
- flu-like symptoms
Here are some tips to help lessen your caffeine intake and reduce the severity of withdrawal symptoms:
- Keep a journal. Knowing how much caffeine you have each day, including caffeine in coffee, tea, chocolate, medications, and foods, can help you cut back. You may be having more than you realize.
- Dont quit cold turkey. This may cause withdrawal symptoms to be more severe. Instead, gradually reduce your caffeine intake. For example, if you have two cups of coffee each morning, have one instead or make yourself a cup that is half decaf and half regular coffee.
- Brew for less. You can easily reduce the amount of caffeine in your morning cup of coffee by simply brewing it for less time.
- Cut the caffeine. Try herbal or decaf teas instead of regular tea.
- Get enough rest. If youre overly tired, you may be more tempted to turn to caffeine for a quick pick-me-up.
- Take a walk. If you feel tired during the day, try walking for 5 to 10 minutes. This may give you a boost of energy and help you avoid that extra cup of coffee.
Treatment for BPH varies. You may not need treatment, or you may need medication or surgery. In addition to limiting caffeine, you may benefit from these lifestyle habits:

Caffeine And Prostate Cancer
Several studies have explored the impact of coffee on prostate cancer. According to the results of recent research conducted by Dr. Chang-Hae Park from the National Cancer Center in South Korea, there is no association between prostate cancer and drinking coffee, but there is still some controversy. To arrive at their conclusion, Park and his team evaluated the results of 12 studies that compared coffee intake and prostate cancer risk. Eight of the studies were case-control studies and four were cohort studies.
Although the investigators found a significant harmful association between coffee consumption and prostate cancer risk in seven of the eight case-control studies, they also noted that the studies had severe limitations that affected the outcomes. None of the cohort studies showed any significant association between coffee consumption and prostate cancer. Therefore, while Park and his team reported there is no evidence that coffee consumption has an effect on prostate cancer, further prospective cohort studies are needed.
The journal Molecular Nutrition and Food Research published a study in 2009 in which researchers evaluated the impact of coffee and tea on prostate health. Investigators concluded that while coffee had no apparent relationship with prostate cancer, evidence from animal and in vitro studies suggests that tea, and especially green tea, is a healthier choice than coffee for prostate health.
Does Coffee Reduce Prostate Cancer Risk
An increasing number of studies have reviewed the link between compounds in coffee and prostate cancer risk. As evidence increases. coffee is getting its share of the spotlight.
Recently, researchers from Kanazawa University Graduate School of Medical Science in Japan tested coffee compounds against prostate cancer in mice. Specifically, they used cells that were resistant to standard cancer drugs, such as cabazitaxel.
When they added kahweol acetate and cafestol to prostate cancer cells in a petri dish, the cells grew less rapidly.
We found that kahweol acetate and cafestol inhibited the growth of the cancer cells in mice, but the combination seemed to work synergistically, leading to significantly slower tumor growth than in untreated mice,
After 11 days, the untreated tumors had grown by around times the original volume , whereas the tumors in the mice treated with both compounds had grown by around just over times the original size. explains study leader, Dr. Hiroaki Iwamoto.

Coffee May Lower Prostate Cancer Risk
Study Shows Regular Drinking of Decaf or Caffeinated Coffee May Protect Against Prostate Cancer
May 17, 2011 — Men who drink coffee regularly appear to lower their risk of prostate cancer, especially the lethal form, new research suggests.
When the researchers looked at all forms of prostate cancer, ”the highest coffee drinkers had about a 20% lower risk of developing prostate cancer during the follow-up,” says researcher Lorelei Mucci, ScD, MPH, associate professor of epidemiology at the Harvard School of Public Health.
The 20% lower risk was found in those drinking six or more cups daily compared to none, she tells WebMD.
Coffee protected even more against the most lethal form of prostate cancer. Among those drinking one to three cups a day, the risk of lethal prostate cancer declined 29%, compared to that of nondrinkers. Among those drinking six or more cups daily, the risk for deadly prostate cancer was reduced 60% compared to that of nondrinkers.
The surprise: the risk reduction held for both regular coffee and decaf, leading the researchers to speculate it’s not the caffeine providing the protection.
The study is published online in the Journal of the National Cancer Institute.
Other research has found coffee can lower the risk of Parkinson’s disease, type 2 diabetes, gallstones, and liver cancer.
Evidence Of Recurrence Risk Decrease
Of particular interest to most of the men in this community is how such research relates to those already diagnosed with prostate cancer. I came across information on a 2013 study that found drinking one cup of coffee a day resulted in a 56% decrease in risk of recurrence or progression compared to drinking one cup or less a week.11
These numbers seem very impressive, however, the lead author noted that: For men who do not drink coffee, it is not possible to recommend that they start drinking coffee based on results from our observational study, especially as some of these men may have medical conditions that could be exacerbated by caffeine or coffee intake.11
This statement mirrors what I said above and further reinforces the need for researchers to move to see if the potentially beneficial components of coffee can be utilized independently to reduce the overall risk of prostate cancer or its most severe forms, as well as the risk of recurrence for those unlucky enough to already have had to live through it.

Drinking 3 or more cups of Italian-style coffee, such as caffé espresso and moka, as well as their combinations with milk, including caffé latte, cappuccino and macchiato, each day can reduce the risk of prostate cancer, according to epidemiological findings published in International Journal of Cancer.
In recent years, we have seen a number of international studies on this issue, but scientific evidence has been considered insufficient to draw conclusions,George Pounis, PhD, from the department of epidemiology and prevention at IRCCS Neuromed in Italy, said in a press release. Moreover, in some cases results were contradictory.
The researchers examined the effect of Italian-style coffee consumption on prostate cancer risk in a cohort of almost 7,000 Italian men aged 50 years and older. The men completed questionnaires for dietary assessment and to evaluate coffee consumption, and were followed for an average of 4.24 years. To evaluate the potentialin vitro effect of antiproliferative and antimetastatic activity of caffeine on prostate cancer cell lines, the researchers tested coffee extracts containing caffeine and decaffeinated coffee extracts on the prostate cancer cell lines PC-3 and DU145, using increasing concentrations of caffeine.

Can Coffee Cause Bph
So far, the research does not point to coffee and caffeine as causes of BPH. One study found that men who drink coffee do have an increased risk of developing BPH, however its important to keep in mind that the research is preliminary, and that other dietary factors should be taken into consideration. For example, other studies have pointed to an association between the development of an enlarged prostate and the reduced consumption of vegetables and legumes.
