Doctors, get a kick out of this: The biology of coffee
You’re reading this with a cup of coffee in your hand, aren’t you? Coffee is the most popular drink in many parts of the world. Americans drink more coffee than soft drink, juice and tea — combined.
How popular is coffee? When news first broke that Prince Harry and Meghan were considering Canada as their new home, Canadian coffee giant Tim Hortons offered free coffee for life as an extra enticement.
The main biologically active ingredients in coffee are caffeine (a stimulant) and a suite of antioxidants.
What do we know about how caffeine and antioxidants affect our bodies? The fundamentals are pretty simple, but the devil is in the details and the speculation around how coffee could either help or harm us runs a bit wild.
