We've heard varying theories over the years about the effects of coffee and caffeine. The latest says that coffee is bad for your heart BUT ONLY if you drink 5 cups a day or more.

But a cup of "joe" in moderation can be good for your heart, memory, pain-relief and energy.

But what exactly is a "cup"?

If you grew up stateside, you’re taught that a cup equals 8 ounces. The recommendation of daily water intake is based on this measurement ― eight cups of 8-ounce glasses of water. But if you’re making coffee, a cup IS NOT defined as 8 ounces, no matter where you are. In fact, a cup of water for making coffee is generally only 6 ounces.

It should be noted that when we are talking energy drinks, less is more.  An average energy drink has the same amount of caffeine as 5 cups of coffee and the equivalent of 17.5 spoonfuls of sugar.
