An extra cup of coffee won’t increase BP risk
Baton Rouge: Data pooled in by researchers from six studies, covering 170,000 people, asked participants how much coffee they drank each day and then followed them for up to 33 years.
The results showed that nearly one in five persons developed high blood pressure, with the chance of diagnosis no different for people who said they drank more than five cups of a coffee a day compared with those who drank very little.
But a member of the research team, Liwei Chen, from the Louisiana State University School of Public Health in New Orleans, said that the relationship between coffee drinking and blood pressure is complicated by the possibility that it does not work the same way for everyone.
“People with a different genetic background may react to coffee differently,” the Daily Mail quoted Chen, as saying.
“For some people maybe it’s safe to drink a lot of coffee, but not for other people,” she said.
“I don’t think of coffee as a risk factor for high blood pressure,’ said blood pressure expert Lawrence Krakoff. However, he stopped short of giving people free rein to guzzle gallons.
“If people are drinking 12 cups a day and are not sleeping, I assume that is an important issue,” he added.
The study has been published in The American Journal of Clinical Nutrition.
