Whatever the reason, coffee rocks.
Get the most out of your cup(s)
Some of the studies above suggest that more is more (remember that 12.5 cups thing?). But there’s a limit to how much coffee you can handle, no matter how low your tank is running. The Mayo Clinic recommends sticking to about four cups of coffee a day, especially if you want to avoid less-than-awesome side effects, like insomnia, jitteriness, and an upset stomach.
Also, don’t be fooled into thinking that the fancy and frilly drinks are as good for you as plain coffee. “If you want the true benefits of coffee, just have it black or with a little milk,” says Cipullo. All the sugar and the almond-mocha-pumpkin-spiced whatever may negate or neutralize the good stuff.
