1. Boost Your Blood Flow

A new study presented at an American Heart Association meeting found that young adults who drank a cup of caffeinated coffee boosted their blood flow compared to when they drank decaf. Researchers looked at blood flow in the finger, which indicates how well the body's smallest blood vessels-particularly, the inner linings of these blood vessels-work. Studies have linked poor function of this lining to an increased risk of heart attack, heart disease and stroke. The researchers suspect that caffeine opens up blood vessels and has anti-inflammatory properties.

2. Improve Your Outlook

Researchers at the Harvard School of Public Health reviewed data from three large studies–of nearly 200,000 adults-and found that the risk of suicide for adults who drank two to four cups of caffeinated coffee per day was half that of those who drank decaf or little or no coffee. The researchers believe that caffeine boosts neurotransmitters in the brain, such as serotonin, dopamine and noradrenaline-acting as a mild antidepressant.

3. Cut Your Risk of Oral Cancer

People who drank at least one cup of caffeinated coffee a day cut their risk of developing throat or mouth cancer compared to those who drank none. The risk was 20 percent lower among those who drank one to two cups daily and 50 percent less if they drank more than four cups, states a study in the American Journal of Epidemiology. The authors say more research needs to be done to understand why.
