Caffeine Can Effect Blood Pressure In A Positive Way [Study]

A new study by the Preventive and Clinical Investigations Center in Paris suggests that moderate caffeine consumption effects blood pressure in a positive way by lowering blood pressure for drinkers.

The study suggests that drinking up to four cups of coffee per day may decrease blood pressure while drinking more than four cups could increase a drinker’s blood pressure.

While the study focused on coffee and tea drinkers, it is possible that other caffeinated beverages may have the same or a similar effect.

The study runs counter to current suggestions which claim that people with high blood pressure should avoid caffeine all together.

Researchers for the study monitored the blood pressure for men and women aged between 16 and 95. The research was conducted over a ten year period.

Subjects for the study were asked to record their daily coffee and tea intake. Researchers broke coffee and tea drinkers up into tree groups: abstainers, people who drank one to four cups a day, and drinkers who consumed more than four caffeinated coffee or tea beverages. 

The study found that heavy tea drinkers benefited the most by producing the lowest systolic and diastolic blood pressure readings. Heavy tea drinkers also had the lowest pulse pressure and heart rate.

While researchers believe flavonoids in tea could help relax blood vessels, they have not yet discovered a direct link.

Researchers found that the group with the highest pulse pressure and heart rate were those who abstained from coffee and tea.

While the difference in blood pressure was small researchers claim, it was still scientifically significant.

In the meantime, researchers argue that  too much caffeine consumption can cause hypertension and other health problems that may or may not be known at this time.

The National Institute for Health and Care Excellence continues to discourage the consumption of too much caffeine. In one study we recently reported on it was claimed that too much coffee drinking can trigger a mental disorder.

With so many studies available, the best course of action might be moderation.

Do you think coffee has positive benefits that need to be further explored?
