Studies show that people who drink coffee are 10% less at risk for depression. Coffee's energy boost partly has to do with its high antioxidants. After all, not all drinks that have caffeine in them are good for you. This is escpecially true with some Coke products which can actually cause depression. Coffee can also protect our body from Type 2 diabetes as well as Alzheimers desies.
BUT just because you think you need a huge energy boost don't drink a million cups of coffee which can cause a massive sugar rush. Usually 2 or 3 cups are about all you need to get your energy going.
