Babies fed formula from BPA-containing bottles also have high levels in their bodies. BPA is said to mimic the structure and function of the hormone estrogen 2. Due to its estrogen-like shape, BPA can bind to estrogen receptors and influence bodily processes, such as growth, cell repair, fetal development, energy levels , and reproduction.
In addition, BPA may also interact with other hormone receptors, such as those for your thyroid, thus altering their function 8. Its use has already been restricted in the EU, Canada, China, and Malaysia — particularly in products for babies and young children. In , the FDA released its latest report, which confirmed the original s daily exposure limit of 23 mcg per pound of body weight 50 mcg per kg and concluded that BPA is probably safe at the levels currently allowed 9. However, research in rodents shows negative effects of BPA at much lower levels — as little as 4.
BPA has a similar structure as the hormone estrogen. It may bind to estrogen receptors, affecting many bodily functions. One study observed that women with frequent miscarriages had about three times as much BPA in their blood as women with successful pregnancies A separate study found that men with higher BPA levels were 3—4 times more likely to have a low sperm concentration and low sperm count Additionally, men working in BPA manufacturing companies in China reported 4.
Although such effects are notable, several recent reviews agree that more studies are needed to strengthen the body of evidence 8 , 19 , 20 , Several studies show that BPA can negatively affect many aspects of both male and female fertility. Most studies — but not all — have observed that children born to mothers exposed to BPA at work weigh up to 0.
In addition, children born to mothers with higher BPA levels were more hyperactive , anxious, and depressed. They also showed 1.
Finally, BPA exposure during early life is also thought to influence prostate and breast tissue development in ways that increase cancer risk. However, while there are ample animal studies to support this, human studies are less conclusive 29 , 30 , 31 , 32 , 33 , BPA exposure during early life may influence birth weight, hormonal development, behavior, and cancer risk in later life.
However, some studies found no links between BPA and these diseases 40 , 41 , Higher BPA levels are associated with an increased risk of type 2 diabetes, high blood pressure, and heart disease. Interestingly, similar patterns have been observed in children and adolescents 48 , Error Include a valid email address.

Here are six non-obvious places BPA is present , so you can make more informed choices about what you buy. Plastic containers are not the only place BPA is found in your kitchen. CNN reported a study found that high concentrations of BPA are found in soup and pasta cans , as well as fruit and vegetable canned goods.
It's important to note that the study found no increased exposure to BPA in canned meats or fish. In fact, the research confirmed that canned goods may be one of the largest risk factors when it comes to BPA exposure. You might want to think twice the next time you ask for a copy of your receipt. A small study published in January estimated that 90 percent of purchase receipts , made of "thermal paper," contained BPA.
Further, while the Center For Environmental Health reported in that many major companies were opting to rid receipts of BPA, it was replaced with another chemical called BPS — which, like BPA, is an endocrine receptor that poses health risks. Style, comfort, and UV protection are probably the three largest factors you weigh when picking out sunglasses, but searching for a pair that's also BPA-free may be worthwhile.
