Drinking coffee does not cause the risk of high blood pressure
High blood pressure is closely associated with heart disease, stroke and shorter life expectancy. Some scientists warn that coffee may increase the risk of high blood pressure. However, according to the latest foreign media reports, a new study published in the American Journal of Clinical Nutrition has found that drinking coffee may not lead to the risk of high blood pressure.
In the latest study, researchers at Louisiana State University School of Public Health analyzed data from six earlier studies involving more than 170000 people. The scientists surveyed participants' daily coffee intake (from less than 1 cup to more than 5 cups, etc.) one by one, and then followed them for 33 years. It turned out that only 20% of the participants ended up with high blood pressure. However, there was no difference in the diagnosis of high blood pressure between people who drank less than one cup of coffee a day and those who drank more than five cups of coffee a day.
Dr. Chen Liwei, head of the new study, said the new findings do not mean that "drinking a lot of coffee is not dangerous." More confirmation data is needed before reaching a conclusion. However, the results also showed that people who drank three cups of coffee a day had a slightly higher risk of high blood pressure than those who drank less coffee. The researchers say this phenomenon cannot be explained at present and needs further research and exploration.
