Coffee is more than just a drink, it’s a passion. Or an addiction. Millions of people all over the world can’t start their day off without a cup of joe, and for many, just one cup doesn’t cut it. The allure is understandable: coffee is aromatic, rich in taste and gets the blood flowing. It also has a lot of health benefits (more on that later), but like most other things, too much of it can cause some major harm.
