BPA in Canned Goods Purportedly Raises Blood Pressure

Researchers with Seoul National University have published a study allegedly
finding that people who drank soy milk from cans containing bisphenol A
(BPA) exhibited a statistically significant increase in blood pressure. Sanghyuk
Bae and Yun-Chul Hong, “Exposure to Bisphenol A From Drinking Canned
Beverage Increases Blood Pressure,” Hypertension, December 2014. Involving
60 adults older than age 60, the study tracked blood pressure and urinary BPA
levels over the course of three visits, during which participants consumed
soy milk from either two glass bottles, two cans or one glass bottle and one
can. Not only did urinary BPA increase by approximately 1600 percent in
volunteers who consumed canned soy milk as opposed to soy milk from glass
bottles, but systolic blood pressure also increased by approximately
4.5 mm Hg.

“Because these results confirm findings from other studies, doctors and
patients, particularly those with high blood pressure or heart disease, should
be aware of the possible risks from increased blood pressure when consuming
canned foods or beverages,” one of the authors was quoted as saying. See
