Why You Should Drink Coffee

Some people have told you that it's not good to drink too much coffee. Actually, drinking several cups a day has many benefits!

There's also evidence that coffee may ward off depression, and even help prevent cavities.

Are you a coffee drinker? How many cups have you had today, two, three, eight?

Well, a Harvard study has found that men that drink six or more cups of coffee a day could reduce their risk of having diabetes by 54%.

That does sound good, although six cups seems like a lot.

Other studies have shown that drinking at least three cups a day is associated with lowering your risk for Parkinson’s disease by 80%. There’s also evidence that coffee may ward off depression, and even help prevent cavities.

All that sounds great, but what if you don’t want all that caffeine? Caffeine can be a major cause of insomnia and anxiety. When you drink too much coffee you may become jittery or have tremors.

We don’t mean to suggest that it’s always good to consume tons of caffeine, but the good news is decaf coffee is still really healthful. It turns out that even decaf coffee is brimming with antioxidants, which help get rid of particles called free radicals that can cause cancer and other diseases.
