Fact: There are 100 million total coffee drinkers in the United States based on July 2014 data gathered by Statistic Brain. Have you wondered why you're feeling jittery when you drink 3 or more cups of your favorite coffee? Genetics may be a risk factor for coffee drinkers to have heart attacks a study in Toronto, Canada suggests.
For some, consuming three cups of coffee a day keep them on-the-go, while for others 3 cups could already be bad for their heart. And the main reason behind this can be attributed to your genetic make-up. A 2006 research from the University of Toronto in Canada was published in the Journal of the American Medical Association (JAMA) proving that genetics determine whether caffeine in coffee is related with the occurrence of heart disease.
The study involving 4,000 people in Costa Rica revealed that there were 2,014 of them who had a non-fatal heart attack from 1994 to 2004. The explanation for this boils down to their genes. People with slow caffeine metabolism have 36 percent chances of having heart attack when they drink 2 to 3 cups of coffee in a day. Even higher risk of heart attack was shown for 'slow metabolizers' if they consumed 4 cups or more. The result also suggests that people younger than 50 with high metabolism have lower chances of encountering heart attack.
The discovery provides insight on the reason why caffeine influences people in different way as manifested on their coffee drinking habits. Although the research is just preliminary, researchers propose that people must observe a clean lifestyle as it also affects the chances of developing coronary problem. Watching your diet, avoid smoking and alcohol drinking, doing regular exercise, and drinking 8 glasses of water or more are the best ways to really keep heart attack at bay.
