What You'll Learn
Bisphenol A (BPA) is not considered cancer-causing in people
Bisphenol A, or BPA, is a chemical found in many hard plastics that people use daily. It is also present in some water bottles, baby bottles, dental fillings and sealants, dental and medical devices, safety equipment, compact disks, household electronic items, and sports equipment. It is a known hormone disruptor and a recognized reproductive toxicant. Studies have shown that exposure to BPA before birth could have long-term effects on carcinogenesis in certain organs, which could lead to the development of hormone-related cancers.
Despite these findings, the Food Standards Agency (FSA) in the UK concluded in 2017 that "BPA is not cancer-causing in people". This assessment was updated in July 2024. The FSA is responsible for ensuring that plastic and other materials used for storing food and drink are safe. They state that any chemicals that may leach from plastic containers into food or drink are present at very low levels and will not cause cancer.
Similarly, Cancer Research UK affirms that there is "no reliable evidence from studies of people that food and drinks stored in plastic cause cancer." While some studies have suggested that certain chemicals found in plastics have cancer-causing effects, these experiments were conducted on animals or in lab settings that may not accurately reflect how humans interact with plastics in everyday life.
It is important to note that public health authorities, such as the Food and Drug Administration (FDA), have recognized the potential health risks associated with BPA exposure. In response, they have set safety levels and taken steps to reduce BPA usage in certain products, particularly those intended for children. For example, several US states have banned BPA in baby bottles, sippy cups, infant formula containers, and childcare products.

Plastic is generally non-toxic and inert
There is no reliable evidence that food and drinks stored in plastic cause cancer. Studies that have suggested a link between chemicals found in certain plastics and cancer have been conducted on animals or used cells in a lab. These studies are not realistic representations of how humans interact with plastics in everyday life and therefore do not provide good evidence of cancer risk in people.
The UK's Food Standards Agency is responsible for ensuring that plastic and other materials used for storing food and drink are safe. The Agency has concluded that bisphenol A (BPA), a chemical used to make some plastics found in food containers, reusable bottles, and as a lining in food tins and drink cans, is not cancer-causing in people. While some BPA may pass into food and drinks, the amount is too small to cause harm. Our bodies break down and eliminate most of the BPA within a short time.
However, it is important to note that some chemicals in plastic, such as bisphenols and phthalates, can have long-lasting effects on health even at low doses. These compounds, known as endocrine disrupters, can affect the same biological receptors that hormones do in our bodies. Exposure to endocrine disrupters has been linked to various health issues, including impaired fertility, maternal breast cancer risk, and problems with brain development in young children.

Plastic production facilities have been linked to increased cancer risk
While there is no direct evidence that chewing on plastic causes cancer, the production of plastic has been linked to an increased cancer risk. Plastic is made from various chemicals, some of which are known to be toxic and harmful to human health. The potential dangers of plastic become more prominent when heated or burned, as this can cause the release of toxic chemicals.
The chemicals used in plastic production, such as bisphenols, phthalates, and vinyl chloride, have been linked to an increased risk of certain cancers. Researchers have found higher rates of leukemia and lymphoma, lung cancer, and other health issues in areas near plastic production facilities. These chemicals can act as endocrine disrupters, affecting the body's hormone system and leading to neurodevelopmental problems, metabolic disorders, and reproductive issues.
Bisphenol-A (BPA), for example, is a chemical used in food containers, reusable bottles, and can linings. While studies suggest that the amount of BPA that can leach into food and drinks is too small to cause harm, it is still a potential concern. The body can break down and eliminate most of the BPA within a short time, but prolonged exposure or higher doses may have unknown effects.
Additionally, the impact of microplastics on human health is a growing concern. Microplastics may act as carriers for other toxic chemicals, potentially increasing their harmful effects. While the specific mechanisms are still being studied, initial findings suggest links to male fertility issues, biomarkers of colon and gut cancer, and respiratory problems.
Overall, while chewing on plastic may not directly cause cancer, the chemicals in plastic and the proximity to plastic production facilities have been associated with an increased risk of cancer and other health issues. It is essential to be cautious and minimize exposure to potentially harmful substances whenever possible.

Studies on animals suggest some chemicals in plastic may cause cancer
While there is no reliable evidence from human studies that consuming food and drinks stored in plastic cause cancer, some studies on animals suggest that certain chemicals found in specific plastics may have cancer-causing effects. These chemicals include bisphenols, phthalates, and vinyl chloride.
Bisphenol A (BPA), for example, is a chemical used in making some plastics, including food containers, reusable bottles, and linings in food tins and drink cans. While BPA can leach into food and drinks, the amount is considered too small to cause harm. The body also quickly breaks down and eliminates most of the BPA within a short time.
Phthalates, another chemical found in plastics, have been linked to disruptions in the endocrine or hormone system, leading to neurodevelopmental problems, metabolic disorders, and reproductive issues. Exposure to phthalates during pregnancy may also impact the developing child, increasing the risk of obesity, metabolic disorders, and neurodevelopmental and reproductive issues.
Additionally, vinyl chloride, a compound used in plastic production, has been associated with an increased risk of certain cancers, such as leukemia and lymphoma, in areas near plastic manufacturing facilities.
It is important to note that the studies on animals or cells in a lab involve direct exposure to high concentrations of these chemicals, which may not accurately represent how humans interact with plastics in everyday life. Regulatory bodies like the Food Standards Agency in the UK ensure that materials used for storing and packaging food are safe and that any chemical migration from plastic containers into food or drinks is at low, non-harmful levels.
