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.
Hey, man, drink what you want. It doesn't change my life in any way, shape, or form. But I have to ask, have you seen the image describing where decaf coffee comes from?
My question is whether espresso-method coffee has all the same properties. The study itself clearly states "brewed coffee" and they brew the crap out of it ("extraction in boiling water for 8–10 min"), I can't take brewed coffee on the regular b/c it upsets my stomach.
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.
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!
For the health benefits, without some of the downsides, I believe it is preferable to drink coffee when you are not tired. This way you don't get a crash later, because there is no adenosine build-up (the 'tiredness' signaling molecule that caffeine blocks). I believe this also helps to prevent addiction, because there is also no up-regulation of adenosine receptors.
This works great if you drink coffee for the taste, rather than as a way to stay awake (which works in a pinch but is counter-productive over the long term).
I generally always sleep well, but enjoy a nice big cup of coffee in the morning. If I'm really sleep deprived, I switch to black tea. Seems odd because you'd think less caffeine would be worse, but the tea is easier on the stomach and somehow "evens out" the sleep deprivation better.

All you haters that give me grief for drinking my daily cup of decaf can shut up now.

I do find it amusing. But drink your decaf, brother, do what works for you.
