In more bisphenol A (BPA)-related news, a second study has confirmed that there is indeed a link between BPA and heart disease. Scientists found during their research that people with higher levels of BPA in their urine were more likely to have heart disease than those with lower levels of BPA.

The first study that linked BPA to cardiovascular problems was published in 2008 (heart disease and diabetes, to be specific), but until now there has not been another study performed that corroborates the evidence. This most recent study uses a broader subject group and produces the same results as the 2008 study, albeight with slightly weaker numbers. However, the list of the negative effects of BPA continues to grow: mimicking the effects of estrogen, lower sperm counts, prostate cancer, developmental & behavioral problems, and now heart disease. Unfortunately, the American Chemistry Council, a lobbyist group in Arlington, Virginia has disputed all claims against BPA, making it difficult for regulations to be put into place by the government in regards to BPA in products that come in contact with food. The chemical has been found in a multitude of items, ranging from water and baby bottles, to the lining of tin cans.

So, if you’re planning on buying a new water bottle, travel mug, or really anything that you carry drinks or food in, make sure that it’s BPA-free. While most agree that stainless steel is best, for other products it isn’t feasible (hydration bladders, just to name one). Quite a few companies these days are making sure to label their products “BPA-free” so just check the label if you are unsure.
