I’m pretty sure that the extra stuff people add to it are most likely worse than the coffee is.

James Hoffmann recently released an interesting video over this. https://youtu.be/rABfboy0h6o

Short version: yes. As long as sugar and other junk isn’t added. Generally any intake of coffee has benefits over none; and 3-4 cups a day of coffee seemingly the sweet spot. Coffee intake should be minimal/none if pregnant. More studies are still needed on the topic.

Here’s a meta analysis (review of many studies) from the British Medical Association. I removed some wording to shorten their conclusion. https://www.bmj.com/content/359/bmj.j5024

Coffee consumption was more often associated with benefit than harm for a range of health outcomes […] with summary estimates indicating largest relative risk reduction at intakes of three to four cups a day versus none, including all cause mortality (relative risk 0.83, 95% confidence interval 0.83 to 0.88), cardiovascular mortality (0.81, 0.72 to 0.90), and cardiovascular disease (0.85, 0.80 to 0.90). High versus low consumption was associated with an 18% lower risk of incident cancer (0.82, 0.74 to 0.89). Consumption was also associated with a lower risk of several specific cancers and neurological, metabolic, and liver conditions. Harmful associations were largely nullified by adequate adjustment for smoking, except in pregnancy […] There was also an association between coffee drinking and risk of fracture in women but not in men.

I don’t think its bad for you, in moderation. And depends how you take coffee. Black vs milk and sugar etc

Anecdotal, but I’ve heard that coffee drinkers are more resistant to radiation poisoning than non-drinkers.

Please don’t take me at my word and handle spent reactor rods after chugging an espresso.
