More recently, Britain’s Prince Charles has raved about coffee enemas, and Amazon.com sells DIY kits.
A 2008 study at Sweden’s Lund University demonstrated that drinking coffee lowers the risk of breast cancer, at least for women who have a relatively common variant of the gene CYP1A2, which helps to metabolize both estrogen and coffee.
Around A.D. 1000, Arab traders brought coffee beans home from Africa and started boiling them into a drink they called qahwa. Translation: “that which prevents sleep.”

That is, until they are threatened by disease. Nearly 70 percent of the coffee we drink today comes from offshoots of wild Arabica, or Coffea arabica—the coffee species that stores most of the genetic information we need to re-engineer commercial cultivars.
Bach voiced his love of coffee in a cantata. With libretto by Christian Friedrich Henrici, the Kaffeekantate was first performed in Leipzig, Germany, sometime between 1732 and 1735.
A global phenomenon, the grande (or medium) 16-ounce coffee at Starbucks contains the caffeine equivalent of 9.5 cans of Coke.

It takes approximately 4,700 ounces, or 37 gallons, of water to make just one cup of coffee when you account for inputs needed to grow and process the beans.
The world consumes close to 1.6 billion cups of coffee every day.
