I found this little illustration that has a pretty good summary of the pros and cons of coffee consumption. Coffee is the most consumed beverage in the world and is the go-to source for office employees to get through their days. But besides energy, coffee provides a plethora of other benefits, which are outlined below.
As far as coffee being able to reduce the risk of certain disorders, here are some of the sources:
- Parkinson’s (1, 2)
- Alzheimer’s (1, 2)
- Type II diabetes (1, 2, 3)
- Gallstones (1, 2)
- Cancer – oral esophageal, and pharyngeal (1, 2)
- Asthma (1)
- Hearth rhythm problems (1)
- Strokes (1, 2)
- Cirrhosis of the liver (1, 2)
However, keep in mind that some of these studies found a positive association. But as always, correlation does not imply causation. Many of these studies concluded an inverse relationship between coffee consumption and the mentioned diseases—but falls short of recommending coffee consumption to reduce risk of certain diseases. But that is how clinical studies are—they don’t quite make recommendations; the only objective of the study is to prove their hypothesis.
