Eating food from cans lined with the chemical bisphenol A (BPA) could raise your blood pressure, a new study suggests.
BPA previously has been linked to a variety of ills, including heart problems, developmental problems in children and high blood pressure. The chemical is widely used in products ranging from plastic bottles and food containers to dental fillings and cash register receipts. In cans, BPA is used as a lining, the researchers said.
“We found that drinking two canned beverages increased systolic blood pressure by 5 mm Hg,” said lead researcher Dr. Yun-Chul Hong, director of the Environmental Health Center at Seoul National University College of Medicine in Korea.
Putting that in perspective, he said a 20 mm Hg increase in systolic blood pressure doubles the risk for heart disease. The systolic blood pressure number is always the first of two numbers given in a blood pressure reading.
