Caffeine good for heart health? Study says yes.

Posted: Updated:

WSIL-TV - Caffeine affects your nervous system, but could it be good for your heart? 

As we sip our morning coffee, doctors worry about how caffeine affects the electrical system of your heart. We know that the caffeine in coffee, tea, and energy drinks makes your heart beat faster, but does it trigger your heart into a life-threatening rhythm?

New research says: drink on. Most of the data supports the idea that caffeine is not harmful to your heart's electrical system. And, in a few studies, they find that regular coffee drinkers actually have a decreased risk of certain abnormal rhythms. 

If coffee or tea is your drug of choice, you are in luck -- an in good company.  If it's an energy drink, not so much. While coffee and tea have been proven to be fairly safe, the research suggests that most energy drinks are slightly more risky. In addition to high amounts of caffeine, they often have other ingredients that amplify the body's response to the stimulant, causing more harmful side effects.

This study recommends a maximum of about 3 cups of coffee. And, it's also important to note that caffeine can still trigger certain abnormal rhythms in some people.
