Question

Tim in Essex asked:

Do high roasted coffee beans cause cancer?

Answer

I'm not aware of any evidence that that's the case. The evidence for coffee and cancer is pretty good. It's neither protective nor harmful. The method by which you prepare coffee is quite important, so filtering coffee takes out some of the cholesterol elevating effects of coffee. So boiled coffee is not a good way to prepare it. Cholesterol raising oils are also not present in instant coffee.
