It shocks me that tea and decaff doesn’t show any clear health benefits. Is this study worth listening?

Problem with “cups of coffee” is it’s not an objective measurement.

I know caffeine in the context of coffee has some benefits. I’m surprised decaf showed no benefit as I thought chlorogenic acid, likely present in decaf, had lifespan extension effects.

Evidence has been pretty consistent that coffee is good, though I think having it earlier in the day to stop disruption of sleep is key.
