There are concerns that it may disrupt hormones. Moreover, studies in animals have suggested it may be toxic. BPA is a commonly used chemical. People experience frequent exposure to very small amounts of BPA through food, drinks, and water supplies, because small amounts may migrate from food packaging. In this article, we discuss what BPA is, what its sources are, and what impact it might have on human health. BPA is an endocrine disruptor. For example, it can behave in a similar way to estrogen and other hormones in the human body.
According to the NIEHS , there is limited research to show how endocrine disruptors affect humans, but some research has found they can harm animals. However, even a small amount may have developmental and biological impacts, because the balance of hormones is so sensitive. In , scientists published study findings showing that BPA exposure can affect egg maturation in humans. A review found evidence that BPA can interfere with endocrine function involving the hypothalamus and pituitary gland.
The researchers suggest that this type of action can affect puberty and ovulation and may lead to infertility. The findings indicate that high level exposure may increase the risk of erectile dysfunction and problems with sexual desire and ejaculation. Research in humans has linked even low dose BPA exposure to cardiovascular problems, including coronary artery heart disease, angina , heart attack , hypertension , and peripheral artery disease.
Findings from animal studies indicate this type of exposure could trigger arrhythmias , atherosclerosis , and blood pressure changes. There is evidence that human exposure to BPA may contribute to :.

Hall JM, et al. So while you're running on that treadmill, it might be wise to leave your plastic water bottle at home. At Kablo, we've worked very hard to develop the absolute highest-quality, non-toxic, contaminant-free borosilicate glass water bottles.
We encourage everyone to educate themselves and only use containers that are inert and sanitary for their daily drinkware — many plastic and metal alternatives can leach into your beverage and it is wise to steer clear of soluble materials.
Hundreds of scientific studies in the last 10 years have confirmed a link between BPA and its adverse health effects many of which we've linked. While the FDA suggests that the results are inconclusive, we have reason to be wary of these claims. The FDA is infamous for fabricating research that is funded by industry. Remember how 50 years ago the sugar industry paid FDA scientists to downplay the risks of sugar? We now know that in fact, sugar increases the likelihood of triglycerides, diabetes and even cancer.
Anyone familiar with the inner workings of the FDA should know to take results from their studies with a grain of salt. For some time now, pharmaceutical companies have been able to pay the FDA to fast-track drug approval , calling into question the legitimacy of this institution.
In spite of this, scientists continue to stand behind the science that links BPA with severe health risks. This is by no means a comprehensive list. BPA is found in many packaged goods and plastic beverage containers.
Manufacturers often use BPA to make epoxy resins to coat the inside of metal cans so that they do not corrode. A study published in the journal JAMA has even found that hand sanitizer speeds up the absorption of BPA from paper receipts into the body. Even worse, the cocktail of these chemicals together is doing even more damage to the body. In a study performed in at the University of Texas Medical Branch at Galveston, they found that the combination of multiple endocrine-disruptors caused cell mutation and significant damage to genes.
Call us biased, but borosilicate glass is one of the very few materials you can be sure is free of BPA, lead, phthalates or other endocrine-disrupting chemicals. Did we mention the environmental disaster caused by single-use containers and the plastic bottle industry? Some dental sealants and composites may also contribute to BPA exposure.
The primary source of exposure to BPA for most people is through the diet. While air, dust, and water are other possible sources of exposure, BPA in food and beverages accounts for the majority of daily human exposure. Bisphenol A can leach into food from the protective internal epoxy resin coatings of canned foods and from consumer products such as polycarbonate tableware, food storage containers, water bottles, and baby bottles.
