Here are more fascinating facts about caffeine and cancer.
Caffeine affects the immune system via at least two opposing mechanisms.
Mechanism 1: A2A receptor antagonism (immunostimulatory)
Tumors and damaged tissues release adenosine, which engages the A2A receptor on immune cells and signals them to stand down. Caffeine antagonizes (i.e., blocks) this receptor.
Mechanism 2: Raising intracellular cAMP (immunosuppressive)
Caffeine also inhibits phosphodiesterase, the enzyme that hydrolyzes (i.e., breaks down) cAMP. cAMP accumulates inside immune cells, which acts as a "calm down" signal.
Note: both mechanisms are dose-dependent. At dietary caffeine levels, A2A antagonism likely dominates, whereas PDE inhibition is weak and mainly relevant at higher concentrations. However, the net immune effect in the tumor microenvironment remains unproven.

If you would like to learn more, I can outline a framework for technical folks to ease in and become more informed on cancer. Gaps abound. The more people who understand cancer, the faster we get to cures. Moreover, personalized cancer treatment is the obvious future. Knowledge acquired now may pay off later (but hopefully not needed).
I love coffee, so this is a nice read. Couple years ago I switched to french press, fresh beans (grind on demand) & no milk or sugar - okay, a dash of full cream milk sometimes. Has to be strong - you can't drink weak coffee like that!
Yes, I know the four main methods of decaffeination. The haters have gone down this road with me many times. Why can't people just let me drink my decaf? It's like they can't enjoy their caffeine unless everybody does. It's weirdly pushy.
I don't think GP was criticizing you for liking decaf. Just pointing out that the decaf process may have affects on the beneficial compounds that aren't caffeine.
My initial charitable reading -- as someone who sometimes dabbles in decaf -- is that decaffeination has the bad side effect of stripping flavors, and likely many of the other biologically active chemicals. I can see from their further posts that they were more interested in unscientific fear mongering instead.
That said, I do think there is some truth that decaf is lacking (including via supercritical CO2) and I wonder how long until we could have a product like genetically engineered coffee plants that produce everything except caffeine. I'd like that, though I can immediately see an issue with growing a plant without its natural pesticide.
By "All you haters that give me grief for drinking my daily cup of decaf can shut up now", you are implying that decaf has the same health benefits of real coffee. That's not proven. And if you weren't meaning to imply that, there was no point to that reply.
I love coffee. It's good for you, it smells and tastes so good. It wakes you up, and prevents sleepiness after meals. Its stimulant nature is a plus, but not necessarily the main thing.
Unfortunately the most flavorful methods (espresso, french press, moka) also raise your cholesterol. So sadly, no, coffee is not universally "good for you". Filtered coffee methods are though, as the filter absorbs the oils.
Always so cute how fellow coffee lovers will loudly boast the health benefits of coffee, but when you add an asterisk they will see it as a personal attack and respond strongly :)
Coffee is not what defines your identity. It's fine to admit it isn't perfect.
My point is not that unfiltered coffee is good, I’m just saying that northern italians who eat dessert for breakfast, cook everything in lard, drink unfiltered coffee and even (gasp) sometimes smoke cigarettes are significantly healthier than Americans on every metric.
Not saying those things are necessarily good for you, I’m just saying we don’t seem to understand this stuff very well
I would be very cautious about any conclusions regarding its health benefits or detriments. Nutrition research is notoriously difficult to replicate or show causal links in humans engaging with the real world.
Texas A&M also has a coffee research center dedicated to promoting and protecting global coffee trade and consumption so… yeah.
FYI since many people don't know: Decaf isn't zero, it can still be several percentage points. In the US decaf is supposed to be under 3% of regular coffee but it's not commonly tested or enforced, so many types of decaf can be quite a bit higher. Several big cups of decaf can approach the caffeine content of one regular cup.

Do you have a source for this? Because it doesn't sound right to me. And also, I live in a coffee producing company, work adjacent to the coffee industry, and had a long conversation with someone planning to set up a business exporting green beans to the US, and their beans were getting tested to an extreme degree and being rejected for a few ppm over on certain things.
I have heard the 3% rule but fyi it's 1% in the EU and since there's actually not that many large scale decaffeination factories in the world, as far as I know they all target the EU level.
If you buy small batch, large batch, or somewhere in between it's probably been processed in one of these few large factories.
I am definitely going to do this as I age, I just don't need the stimulant effects as much anymore. That said, the ritual of getting coffee and sipping on something warm in the morning is really important to starting my day right.
Sadly, I can't. I tried all the decaf beans in my area and even some fancy online roastery specialized only in decaf beans, and they all tasted like ass, compared to their caffeinated cousins. So much money wasted trying to find good tasting decaf beans.
Not sure what the decaffeination process does, but it definitely does not preserve the taste of "untouched" beans.
Not everything is dopamine. Maybe nitpicky on my end but it gets tiresome when everyone is just like dopamine this, dopamine that, when no one really understands neurotransmitters.
Haha, I viewed a video recently (in French) that said « dopamine is right-wing ».
It was ironic but interesting : dopamine is viewed as THE neurotransmitter of motivation while in fact it’s only one part of the mechanism. But it’s the part everyone is bragging about because it supports the idea that you can control your dopamine levels and be responsible of your own motivation.
The whole point of the argument was that your serotonin and noradrenaline levels were as much as important if not more, and, fat chance, you cannot buy serotonin or noradrenaline supplements. You have to be in mentally in a good place to get those right and that’s not something you have that much control over. Especially your noradrenaline levels are strongly tied to the quality of your environment and that’s why you should politically fight for a better life environment.
Not exactly, the article says that the effects aren't linked to caffeine, not that decaf has been shown to have the positive effects or still contain the necessary chemicals.
I was never a coffee drinker, but I became interested because what was said in Arnold Schwarzenegger‘s newsletter. ( There is a ton of medical research covered in there. )
I didn’t dig in too deeply, but started drinking a morning cup of sugar free double mocha cappuccino, to help my workouts.
If I’m fooling myself, don’t tell me. I like the cappuccino.
I did use pure nicotine and it was very bad for my health, probably due to high dosage, but still.
I've used heavy stimulants, benzos, opioids, dissociatives without an issue, but nicotine is in a class of its own in terms of how insidiously addictive it is.
But just from a health point of view: extreme arm and hand joint issues, forearm vascular issues that made my hands numb at night, palpitations/arrithmia like I was about to die when I used nicotine before sleep and I was drifting to sleep -- it really felt like I was about to die, like my heart was mangled up.
A lot of people consume nicotine. It has been isolated and used in products for a long time. There's no clear link to cancer, but it could impact cardiovascular health (like all stimulants seem to).
Some research indicates that nicotine can influence how existing cancer behaves and spreads, so that's worth considering.
He was suggesting— jokingly— that maybe coffee cancels out the deleterious effects of smoking, because indeed coffee + a cigar or pipe is truly an excellent experience.
I quit smoking a long time ago but if there's one thing I'm missing / craving is a hot cup of coffee with two cigarettes on an empty stomach during cold winter mornings... Fuuuuck.

All you haters that give me grief for drinking my daily cup of decaf can shut up now.
Unfortunately it isn't without potential downsides.

We do, and that's called cancer;)
