Coffee
is a drink prepared from roasted coffee beans. Darkly colored, bitter,
and slightly acidic, coffee has a stimulating effect on humans,
primarily due to its caffeine content. It is the most popular hot drink
in the world.
Caffeine is the first thing that comes to mind when you think
about coffee. But coffee also contains antioxidants and
other active substances that may reduce internal inflammation and
protect against disease, say nutrition experts from Johns Hopkins
University School of Medicine.
