A new study on the short term effects of BPA is quite revealing.
I know in the past we have talked about BPA, and switching from plastic to glass water bottles. But a new research study done in Seoul, South Korea, sheds even more light on how BPA is affecting our bodies. This study looked at the effects of soy milk being given to 60 participates over the age of 60 in either two glass containers, two cans, or one glass and one can combination. The reason soy milk was used in this study is that it does not have any effect on the heart. The researchers were looking at the effects of BPA on blood pressure as well as how much BPA was eliminated via urine from these participates.
Two hours after drinking the soy milk in the above containers, blood pressures readings were taken as were the urinary BPA levels. Urinary output of BPA rose by up to 1,600% in canned soy milk drinkers in comparison to the glass soy milk drinkers. While systolic blood pressure increased by 4.5mmHg in can drinkers vs glass drinkers. Prior to the samples the participants were not to eat for 8 hours, nor for the two hours between drinking the soy milk and testing so that there would be no other conflicting factors.
This study looks at short term effects of BPA on the body, but what about chronic exposure? If we are getting exposed to BPA on a daily basis, or even several times a day, how does that affect our body on a cardiovascular level? Not forgetting to mention the hormone disruption effects of BPA, and more that we are finding out about it as the years go by. I hope this study, and others like it, is looked at by regulators when it comes to what we allow in our foods. We, as consumers, need to make wiser choices for ourselves including leaving the canned items on the shelves, and making homemade soup that we can then store in glass containers if need be. I know there are some companies out there that are lining their cans with something other than BPA, but what exactly is that replacement, and how will that replacement affect us long term.
