Ganolife Coffee Is Better For Your Heart Part 5

This Is Your Heart on Energy Drinks. Your heart responds to the high levels of caffeine in energy drinks in more ways than one. By Jennifer J. Brown, PhD, Everyday Health Staff Writer. Coffee: The Original Energy Drink An average cup of coffee contains about 100 mgs of caffeine, with ranges from 60 to 150 mgs per cup. The body rapidly absorbs caffeine, which boosts adrenalin circulating in your blood. Low to moderate amounts of caffeine from coffee (or tea) are generally considered safe. "Coffee in moderation is reasonable. The CDC recommends no more than 400 mg a day [for adults]. This is a bit high, in my opinion," said Campbell. Even in people with heart disease, he said, one or two cups of coffee a day are unlikely to cause problems. Still, some people feel abnormal heart rhythms after drinking coffee. "Although most people can tolerate the effects of caffeine on the heart, there are cardiac conditions that are genetic and acquired in which exposure to high doses of caffeine can result in an abnormal heart rhythm," explained Dr. Bunch. In this case it is a good idea to stop consuming anything with caffeine in it, to see if the heart symptoms stop. If the heart rhythm issues persist, be sure to consult your doctor.
