Heavy coffee drinkers with high blood pressure had higher risk of death: study

• People with very high blood pressure who drank a lot of coffee were more likely to die from heart problems, according to a new study.
• But drinking coffee had no effect on people with normal or slightly elevated blood pressure.
• Previous research has shown that drinking one to two cups of coffee a day can improve heart health.

Coffee, which is generally considered a heart healthy drink if consumed in moderate amounts, it can be harmful to people with very high blood pressure.

Two or more cups of coffee a day was linked to a higher risk of death from heart problems in people with very high blood pressure, according to research study published Wednesday in the Journal of the American Heart Association.

Compared to non-coffee drinkers, people who drank two or more cups of coffee were twice as likely to die from heart problems in the study.

Although heavy coffee drinking was more risky for people with severe hypertension, or high blood pressure, the same trend did not appear in people with normal or slightly elevated blood pressure. The authors of the study were Japanese researchers who analyzed the health data of 18,609 participants between the ages of 40 and 79.

Consumption of green tea in any amount had no effect on heart health, according to the study.

The study was the first to find a link between drinking coffee and death from heart disease in people with very high blood pressure, lead study author Hiroyasu Iso told the American Heart Association.

Blood pressure is measured by the pressure in your arteries both when your heart is beating (systolic blood pressure) and when your heart is resting (diastolic blood pressure). High blood pressure occurs when your systolic blood pressure is at least 130 millimeters of mercury (mm Hg) compared to a diastolic blood pressure of at least 80 mm Hg.

The study authors defined “very high” blood pressure as at least 160 mm Hg above at least 100 mm Hg.

“These findings may support the proposition that people with severe high blood pressure should avoid excessive coffee consumption,” said Iso at the AHA. rid.

The AHA doesn’t have an official recommendation on how much coffee to drink, but the group said one to two cups a day “does not appear to be harmful.” Web page.

Previous research has shown that moderate caffeine consumption — about one to three cups a day — can benefit heart health.

AND paper from last year that looked at three studies, including one that followed 21,000 adults for at least 10 years, found that drinking two cups of coffee a day can reduce the risk of heart failure by 30%. Previous research also found that roughly three cups of joe a day could reduce the risk of heart disease, Sara Lindberg from Insider reported.

Drinking coffee is even thought to prevent premature death, as a large study from earlier this year analyzing the health of 171,000 UK residents found that regular drinkers of unsweetened coffee were 16 to 21% less likely to die but their peers without Java.

But more recent studies have shed light on the potentially negative effects of coffee. A recent paper in the Journal of the American Medical Association found that drinking coffee during pregnancy can affect the child’s height when they grow up.
