BPA associated with high blood pressure.

bpaBPA also called Bisphenol A (BPA) is a common chemical, found in products such as plastic bottles and the inner lining of certain food cans.

The chemical has been associated with an adverse and BPA exposure has been detected in 95% of the U.S. population.

A new study, published in the journal Hypertension, has followed up on previous work associating BPA with such as and variability.

“A 5 mmHg increase in systolic blood pressure by drinking two canned beverages may cause clinically significant problems, particularly in patients with or hypertension,” said Dr. Yun-Chul Hong of Seoul National University College of Medicine in . “A 20 mmHg increase in systolic blood pressure doubles the .”

The study consisted of a randomized crossover trial where 60 research participants were randomly provided with soy in either cans or glass bottles. After 2 hours, the participants’ blood pressure, variability and urinary BPA concentration were measured. Participants were asked not to eat or drink any other food for the 2 hours after drinking the soy , and for at least 8 hours before each trial.

The research findings revealed that drinking from cans is associated with a urinary BPA concentration increase of 1,600%. Soy is not associated with the ability to increase blood pressure. Systolic blood pressure increased by approximately 4.5 mmHg after the consumption of two canned beverages, compared with after the consumption of two glass-bottled beverages. No statistically significant differences in variability were observed.

The senior , Dr. Hong, has suggested avoiding exposure to BPA: “I suggest consumers try to eat fresh foods or glass bottle-contained foods rather than canned foods and hopefully, manufacturers will develop and use healthy alternatives to BPA for the inner lining of can containers,” he said.
