TAKE-HOME MESSAGE

Coffee and tea contain antioxidant properties that may affect one’s risk of prostate cancer. The authors of this study identified 7036 men diagnosed with prostate cancer within the EPIC study—a multi-institutional study involving 10 European counties. The risks associated with prostate cancer were evaluated by comparing individuals consuming the most coffee or tea and individuals consuming the least. There was no association found between high vs low consumption of coffee (HR, 1.02 for risk of prostate cancer; HR, 0.97 for risk of fatal disease) or tea (HR, 0.98 for risk of prostate cancer; HR, 0.89 for fatal disease).

Limitations to this study include self-reporting of coffee/tea intake as well as variation in the strength and type of coffee/tea. Nevertheless, these prospectively collected data suggest that there is no association between coffee or tea consumption and risk of prostate cancer.

"the HRs were ... 0.89 ... for risk of fatal disease" [1]

"EPIC is a prospective study designed to investigate the relationships between diet, lifestyle and environmental factors and the incidence of different forms of cancer. The methods have been described in full elsewhere.5 The total cohort comprises subcohorts of men and women recruited in 23 centers in 10 European countries: Denmark, France, Germany, Greece, Italy, The Netherlands, Norway, Spain, Sweden and the United Kingdom."

PCa mortality rate per 100,000 men [2]:

Norway - 106.5

Sweden - 103.0

UK - 80.7

Greece - 15.12 [3]

Spain - 13.84 [4]

Italy - 12.19 [4]

Quite a range!

There is something perverse about commingling data from populations with such different PCa mortality experience.

& coffee consumption varies by amount & preparation styles. Many Swedes favor the traditional boiled method [kokkaffe], which preserves volatile oils.

The Nordics have the highest coffee consumption [an average of 8.2kg of coffee per person, per year in Sweden; 9.9kg in Norway]. Italians have an average of 5.4kg. [6]

Italians are more likely to drink espresso or other dark coffees than Brits, say, where coffee can be milky. The casein in milk binds with the tanins & other polyphenols in coffee (& tea), effectively making the drink medicinally worthless.

An Italian study from 2017 [7]:

"Our study aimed at evaluating in a population cohort the effect of Italian‐style coffee consumption on prostate cancer risk ... 6,989 men of the Moli‐sani cohort aged ≥50 years were followed for a mean of 4.24 ± 1.35 years and 100 new prostate cancer cases were identified."

"The newly diagnosed prostate cancer participants presented lower coffee consumption (60.1 ± 51.3 g/day) compared to the disease‐free population (74.0 ± 51.7 g/day) ... Multiadjusted analysis showed that the subjects at highest consumption (>3 cups/day) had 53% lower prostate cancer risk as compared to participants at the lowest consumption (0–2 cups/day) ..."

Italian data was subsumed into the EPIC study & no doubt weakened by the milky coffee drinkers.

Do you know whether other kinds of plant based milks ruin the medicinal properties of coffee if added to it?

Graham,

I don't. But if the 'milk' reduces bitterness, it is likely removing the tanins.

Personal question. Do you drink coffee black...? thanks

The Aeropress I use produces coffee with hardly any bitterness, but I still need a dash of milk & a little fructose to get it to my taste.

For maximum benefit, one should take it black. The casein in milk binds to polyphenols in the coffee.

Black coffee drinkers are a breed apart IMO. They seem able to drink coffee that was brewed hours ago & tastes like battery acid, without adding anything to counteract it. (I hope Nalakrats doesn't get upset with that observation.)

Patrick, Thank you. There are Europeans who drink their coffee black. We go to restaurants where they serve very bitter coffee in demitasse cups. One has to acquire a taste for this very strong bitter coffee with sediment at the bottom of the cup!! Me, lots of milk, no sugar, please... :D

The inventor of the Aeropress identified two enemies of coffee. Bitterness is due either to high heat or long brewing time.

Espresso makers use steam. With a restretto, you get half the liquid & a lot of good flavor. The liquid you are forgoing tastes of the ashtray.

Similarly, the last cup dripping into the drip pot is detrimental to enjoyment.

With less bitterness you would need less milk to mask off-flavors. Unless of course, milk is an intrinsic part of your enjoyment.

"Oddly Correct is part of a new breed of high-end coffee shops that have adopted zero tolerance policies on sugar, milk and cream to preserve what they feel is coffee quality. Others simply opt out of selling smaller espresso-based drinks ‘to go’ because they feel the taste suffers if not enjoyed right away."

Remarkable! Patrick....

This study has no value for us. This most poorly designed study was to determine if coffee and tea consumption at various levels prevented Pca. Well we here have Pca!

Many of the research studies, presented by pjoshea13 on this subject, show a benefit to those of us with Pca, resulting from the consumption of the Polyphenolic Compounds, found in Coffee and Tea. If I am not mistaken Patrick has shown that those who consume higher levels of Coffee, and Tea[green and black],have longer PSA doubling times and less agressive cancer upon BCR. If I am wrong, he will correct me, I am sure, as the man has about 700 posts here, and it is easier for him to recollect.

Good Luck, Good Health and Good Health.

Correlation is not causation. There are all sorts of interesting statistical anomalies floating around. If you can't show how they are causally linked, don't bother.

Never give up my 3 cup a day habit..dash of almond milk no sugar...still have to live!
