Bisphenol A, or BPA, is a chemical compound used in the manufacturing of plastics to harden them and make them shatterproof. It is often found in polycarbonate plastics, which are hard, clear or clear-tinted, and unbreakable. While BPA-containing plastics are generally marked with a 7, it is not the only plastic that can leach chemicals into food. Plastics marked with a 1, 2, 4, or 5 are generally considered safe, while plastics marked with a 3, 6, or 7 should be used with caution, especially around food or drink.

BPA is found in many plastic products, including food and drink containers, baby bottles, DVDs, clothing, and water bottles
Bisphenol A (BPA) is a chemical used to make polycarbonate plastic. Polycarbonate plastic is used to make hard plastic items, such as baby bottles, reusable water bottles, food containers, pitchers, tableware, and other storage containers. It is also used in the production of epoxy resins, which are used to coat the inside of metal products like food cans, bottle tops, and water supply pipes.
BPA exposure has been linked to several health problems, including infertility, obesity, heart disease, type 2 diabetes, and cancer. It can interfere with natural hormones in the human body and is especially harmful to pregnant people, unborn babies, infants, and children. Elevated exposure to BPA in children has been linked to early puberty, heart conditions, obesity, weak immune systems, and overall negative effects on health.
Due to health concerns, some jurisdictions have taken steps to reduce exposure to BPA. The US, Canada, and the EU have banned the use of BPA in baby bottles and related products. Bottle producers have switched from polycarbonate to polypropylene, and there is evidence that BPA exposure in infants has decreased as a result. The European Union banned BPA in all food contact materials, including plastic and coated packaging, in December 2024.
To reduce exposure to BPA, people can limit packaged foods that aren't labeled "BPA-free," eat mostly fresh whole foods, and avoid canned foods and plastic water bottles. It is also recommended to use glass bottles and baby bottles instead of plastic ones and to be selective with children's toys, choosing those made from BPA-free materials.

BPA exposure has been linked to health problems such as infertility, obesity, heart disease, and cancer
Bisphenol A (BPA) is a well-known endocrine disruptor. Most human exposure to BPA occurs through the consumption of contaminated food, particularly after heating. BPA exposure has been linked to a range of health problems, including infertility, obesity, heart disease, and an increased risk of certain cancers.
Several studies have found a link between BPA exposure and female infertility. BPA has been detected more frequently in infertile women, suggesting a possible impact on natural conception and spontaneous fecundity. Prenatal, perinatal, and postnatal exposure to BPA can impair ovarian development and function, induce ovarian morphology rearrangement, and impair uterus morphology and function. BPA exposure has also been associated with a higher risk of endometriosis-like lesions and PCOS-like abnormalities.
BPA exposure has also been linked to obesity. In vivo trials indicate that BPA exposure can disrupt endocrine regulation, neuroimmune and signaling pathways, and gut microbiota, leading to overweight or obesity. Additionally, there is evidence that BPA exposure can affect the lipid profile and genes associated with lipolysis, contributing to obesity.
Regarding heart disease, there is growing evidence of a positive association between serum or urinary BPA levels and an increased risk of cardiovascular or cardiometabolic diseases. BPA exposure has been linked to hypertension, increased blood pressure, and heart rate issues. Cardiovascular or cardiometabolic diseases, including diabetes, obesity, hypertension, and heart and kidney diseases, are leading causes of death worldwide.
While the Food and Drug Administration (FDA) claims that BPA is safe for consumers within an acceptable range, researchers have raised concerns. BPA exposure may also have transgenerational effects, impacting subsequent generations.

BPA is an endocrine disruptor, mimicking the hormone estrogen in the body and potentially causing hormonal imbalances
Bisphenol A (BPA) is a synthetic chemical that has been used in high volumes for decades and is known to harm human health. It is one of the highest-volume chemicals produced worldwide and is a building block of polycarbonate plastics, often used for food and beverage storage. BPA is also a component of epoxy resins, which are used to line food and beverage containers.
BPA is an endocrine disruptor, meaning it can interfere with the normal functioning of the hormone system. Specifically, it acts as a xenoestrogen, exhibiting hormone-like properties that mimic the effects of estrogen in the body. While the effect is considered weak, the pervasiveness of BPA-containing materials is concerning as exposure is effectively lifelong.
Studies have shown that BPA can leach from products that come into contact with food and drink, leading to its routine ingestion. It has been detected in the urine of 92% of adult participants from 11 European countries, with levels exceeding recently revised European safety thresholds.
The various adverse effects of BPA exposure include its association with an increased risk of insulin resistance, type 2 diabetes, allergies, and altered cardiac function. BPA can also influence numerous estrogen-related pathways due to its structural similarity to estradiol, potentially causing hormonal imbalances and diseases, including sexual behavior problems and accelerated puberty.
Regulatory measures have been implemented to reduce human exposure to BPA, particularly in infants and children, who are considered to be at greater risk.

The effects of BPA exposure are controversial, with some studies finding no increased health risks while others suggest reducing exposure
Bisphenol A (BPA) is a chemical used to harden plastic, making polycarbonate plastic. It is used to make a variety of products, including hard plastic drinking containers, baby bottles, and the linings of infant formula and food cans. BPA is also present at low levels in indoor air and dust, dental sealants, clothing, medical supplies, auto parts, and building materials.
Some jurisdictions, including the US, Canada, and the EU, have taken steps to reduce exposure, especially for infants and children. This has included banning BPA in baby bottles and related products, as they are considered to be at greater risk. However, the FDA still recognizes BPA as a safe additive in food packaging, although it banned manufacturers from using BPA in baby formula cans, baby bottles, and sippy cups in 2012.
There is emerging research that suggests that even at "safe" levels, BPA exposure may contribute to health problems. These include infertility, obesity, heart disease, type 2 diabetes, and certain cancers. BPA exposure in utero may also affect gene expression, leading to an increased risk of obesity and metabolic disease. Elevated exposure in children has also been linked to early puberty, heart conditions, a weak immune system, and neurodevelopmental issues such as ADHD, anxiety, and depression.

Ways to avoid BPA include choosing glass over plastic, limiting canned foods, and avoiding plastic containers marked with recycling numbers 3 or 7
Bisphenol A (BPA) is an industrial chemical added to many products, including plastic food containers. It is a xenoestrogen, exhibiting hormone-like properties that mimic the effects of estrogen in the body. Exposure to BPA has been linked to several health problems, including infertility, obesity, heart disease, type 2 diabetes, and cancer. While the effects of BPA are very weak, exposure to it is effectively lifelong, leading to concern over possible cumulative effects. Due to the potential health risks, many jurisdictions have taken steps to reduce exposure, especially in infants and children.
- Choose glass over plastic: Drink from glass bottles instead of plastic ones, and use glass baby bottles instead of plastic ones. When purchasing water bottles, opt for glass or stainless steel.
- Limit canned foods: BPA is often used as a coating for the inside of food cans. Rinsing canned food with water can help lower BPA levels, but it is best to limit canned foods or opt for alternatives when possible.
- Avoid plastic containers marked with recycling numbers 3 or 7: These types of plastic are more likely to contain BPA and can leach into foods when heated. Avoid heating plastic containers in the microwave, and never heat food in cans.
- Buy BPA-free products: Look for products labeled "BPA-free," especially when purchasing plastic toys for children. However, be aware that BPA-free packaging may not be a perfect solution, as some alternative chemicals may be just as harmful.
- Choose fresh, whole foods: Eat mostly fresh, whole foods and limit packaged foods that aren't labeled "BPA-free."
While it may be challenging to completely eradicate BPA from your life, following these steps can help reduce your exposure and potential health risks associated with this chemical.
