BPA Exposure from Canned Beverages May Increase Blood Pressure

In a new study, when older adults drank 2 cans of soy milk, their average concentration of urinary bisphenol A (BPA) increased 16 times above baseline within 2 hours. Systolic blood pressure increased 4.5 mm Hg on average. On days when they drank the same beverage from glass bottles, which do not use BPA linings, there was no significant change in their BPA levels or blood pressure. The Hypertension study included 60 older adults who drank soy milk from cans or glass bottles on 3 separate occasions, weeks apart. BPA is an endocrine disruptor that can mimic estrogen.
