I stumbled across this blogpost which claims that coffee is awesome for our bodies but only if it doesn't have mycotoxins (toxins generated by fungi).
To quote them:
One study showed that 91.7% of green coffee beans were contaminated with mold. This is before they were processed, which allows even more mold to grow. Another study showed 52% of green coffee beans and almost 50 percent of brewed coffees are moldy. Coffee is easily one of the largest sources of mycotoxins in the food supply.
They conveniently sell coffee beans that underwent a different process and don't have mycotoxins, so I have to wonder if this is a real problem and if there are ways to avoid it besides buying from them.
Perhaps buying green beans and processing them somehow so the fungi are washed away?

Time to apply a bit of healthy skepticism here:

Conclusion:
Don't believe everything that people tell you - especially people with something to sell. Unless you're drinking gallons of coffee a day, brewed coffee is perfectly safe.
