How Many Cups of Coffee per Day Are Too Many?
From cappuccinos to cold brew, coffee is a must-have to start the day for many people. However, a new study suggests too much coffee can be harmful.
This is what a recent study shows. A University of South Australia study led by Elian Hypponen suggests a couple of cups to start your day probably won't hurt — and may even be good for you. But drinking six or more cups of coffee a day can increase your risk of heart disease by up to 22%, the researchers found. A cup was defined as eight ounces of coffee.
Knowing the limits of what's good for us and what's not is necessary. About one in four deaths in the United States is due to heart disease, according to the U.S. Centers for Disease Control and Prevention. Heart disease is the leading cause of death worldwide. That's why Elian set out to discover how much caffeine causes high blood pressure.
Elian says her findings suggest that sipping two to three cups per day is pretty safe and possibly beneficial. She also notes that if you're generally healthy, lots of evidence suggests that four cups per day shouldn't be harmful.
Even though the research says five cups of coffee is permissible, each person should know his or her own limit. If we begin having difficulty sleeping or feeling nervous, we might have reached our limit for the day.
A. Drink no more than six cups per day.
B. Over the limits and our health will pay for it.
C. Coffee is the most popular drink in the world.
D. But of course, don't forget to listen to our body.
E. The relation between them is quite complicated.
F. As we know, it is a key heart disease risk factor.
G. It sets you off on an energetic morning and prepares you for a busy day.
