Drinking coffee healthily may not lead to the risk of high blood pressure.
High blood pressure is strongly associated with heart disease, stroke and shortened life expectancy. Coffee may increase the risk of high blood pressure, some scientists warn. However, according to the latest reports from foreign media, a new study published in the American Journal of Clinical Nutrition found that drinking coffee may not lead to high blood pressure risk.
In the latest study, researchers at Louisiana State University School of Public Health analyzed data from six earlier studies involving more than 170,000 people. Each of the studies asked participants how much coffee they consumed per day (ranging from less than one cup to more than five cups) and then followed them for 33 years. Only 20% of participants eventually developed high blood pressure. However, there was no difference in hypertension diagnosis between those who drank less than one cup of coffee a day and those who drank more than five cups a day.
Dr. Liwei Chen, who led the new study, said the new findings did not necessarily mean that "drinking a lot of coffee is not dangerous." More corroborating data are needed before conclusions can be drawn. However, the results also showed that people who drank one to three cups of coffee a day had a slightly higher risk of high blood pressure than those who drank less. The researchers said that this phenomenon is currently unexplained and needs further research and exploration.
