A new study shows that drinking 3 to 5 cups of coffee per day may be beneficial to your heart since it lowers the risk of developing clogged arteries that often result in a heart attack.
The new research involved healthy Korean adults that had a daily habit of drinking coffee. Compared to their peers that didn’t embrace the habit, study participants who drank between 3 and 5 cups of the dark beverage on a daily basis were less likely to have their heart vessels clogged with calcium deposits, which signals heart disease.
“The study participants who drank three to four cups had the lowest risk of developing clogged arteries seen in the study. But the risk went down with just one cup per day,”
Dr. Eliseo Guallar, lead-author of the study and an epidemiology researcher at the Bloomberg School of Public Health in Baltimore, published his findings March 2 in the medical journal Heart.
However, researchers said that their results only underscored a link between coffee consumption and a healthy heart, rather than establishing a cause-and-effect relationship. So, they were cautious in recommending that people start drinking more coffee to prevent later heart problems.
However, older studies had linked coffee consumption to increased prevalence of heart attacks, but more and more researchers report that java has a positive effect on cardiovascular health, rather than a negative one.
For instance, a recent review of more than 35 studies found a link between coffee consumption and a lower risk of developing a heart condition. Other studies revealed a link between coffee consumption and lowered risk of developing diabetes.
Still, there are studies that suggest coffee may be a contributing factor to a risk of high cholesterol (the “bad” one, or the LDL) and may lead to higher blood pressure. Yet, scientists reported that the blood pressure issue tends to fade away as the body builds up tolerance.
During the latest research, Dr. Guallar teamed up with his fellow scientists from the Kangbuk Samsung Hospital in Seoul and gathered data on more than 25,000 young healthy individuals that had no heart disease when the study began.
The research team found that the volunteers that drank three to five cups of coffee a day had 40 percent fewer calcium deposits on their heart vessels than their peers that didn’t drink coffee at all. Those who drank two to three cups had 35 percent less calcium, while people who sipped only one cup per day showed a 23 percent decrease in their arterial calcium deposits. After five coffee cups the results didn’t improve further.
Scientists currently speculate that the heart benefits coffee may bring are linked to the high level of antioxidants in the beverage.
