Plastic is everywhere, and it's hard to escape the fact that it is harmful to both our health and the environment. While most Tupperware products are considered safe, some Tupperware food storage containers are made from polycarbonate (plastic #7), which has been shown to leach the harmful hormone-disrupting chemical Bisphenol A (BPA) into food items after repeated uses. Vintage Tupperware has also been found to contain lead, arsenic, mercury, and cadmium. As such, consumers are increasingly opting for alternative materials such as glass, ceramic, or stainless steel for food storage.

Tupperware's plastic composition is similar to other plastic containers
Tupperware is a well-known brand of plastic food containers. They are durable and long-lasting, but their plastic composition is not very different from other plastic containers. Research has shown that plastic food containers can be detrimental to health, as they slowly leach harmful chemicals into the food and drinks we store in them. These chemicals, such as Bisphenol A (BPA) and Bisphenol S (BPS), have been linked to various health issues, including cancer, reproductive disorders, diabetes, obesity, asthma, and birth defects.
Tupperware officially banned the use of BPA in their products in 2010, but vintage Tupperware and other older plastic containers may still contain this harmful chemical. Additionally, some newer plastic container manufacturers have replaced BPA with BPS, which may be even more toxic. It is important to note that not all plastics contain these harmful chemicals, and only a small percentage of plastics have been found to leach toxins.
To minimize exposure to BPA and other toxins, it is recommended to avoid using plastic containers, especially when storing warm food, and to opt for safer alternatives like glass, ceramic, or stainless steel. Plastic containers should also not be used in the microwave, even if they are labelled microwave-safe, as the heat can cause the release of toxins into food.
It is worth mentioning that plastic containers are not the only source of plastic exposure. Plastic bottles, straws, cutlery, and canned foods can also contain harmful chemicals that leach into their contents. Therefore, it is advisable to reduce plastic usage and opt for reusable and safer alternatives whenever possible.
Overall, while Tupperware may be a trusted brand, their plastic composition is similar to other plastic containers, and it is important to be mindful of the potential health risks associated with plastic usage and to take steps to minimize exposure to harmful chemicals.

Tupperware's plastic can leach harmful chemicals into food
Plastic is everywhere, and it has become a generic term for any plastic container. Tupperware is a big household name for durable, hard plastic food containers. They are so durable, in fact, that they are still kicking around in many kitchens, even though Tupperware officially outlawed the use of Bisphenol A (BPA) in their products in 2010.
Tupperware's plastic containers can leach harmful chemicals into food. Research has shown that plastic food containers can be extremely detrimental to our health. Plastic containers slowly leach chemicals into the food and drinks we store in them. A 2023 experiment showed that PFAS could transfer into food, and if PFAS is in your food storage, it will transfer into your food over time.
Bisphenol A (BPA) is a harmful hormone-disrupting chemical that has been shown to leach into food items after repeated uses. It has been linked to various health problems, especially certain types of cancer and reproductive disorders. When we place warm food in plastic, BPA-filled containers, toxins from the containers leach into our food. These toxins are endocrine disruptors, mimicking our hormones and creating hormonal and gut imbalances.
Other chemicals can also be found in various food storage containers. For example, black plastic containers have been found to contain hazardous flame retardants, which interfere with hormones and potentially harm sexual function and fertility.
To minimize your exposure to BPA, pay attention to the amount of plastic your food comes into contact with. Swap out your plastic Tupperware containers with glass containers.

Tupperware's plastic may contain Bisphenol A (BPA)
Bisphenol A (BPA) is a chemical used in the production of polycarbonate plastics and epoxy resins. It is commonly found in products such as shatterproof windows, eyewear, water bottles, and epoxy resins that coat metal food cans, bottle tops, and water supply pipes. The primary source of exposure to BPA for most people is through their diet, with BPA leaching into food from the protective internal epoxy resin coatings of canned foods and from consumer products such as polycarbonate tableware, food storage containers, and baby bottles.
Tupperware, a popular brand of plastic food storage containers, has come under scrutiny for the potential presence of BPA in its products. While the company claims that its products are safe, some consumers have expressed concerns about the potential health risks associated with BPA exposure. Tupperware's food storage containers have been found to use polycarbonate (plastic #7), which has been shown to leach BPA into food items after repeated use.
The potential health effects of BPA exposure have been a subject of research and debate. Some studies have linked BPA exposure to various health problems, particularly hormone-related issues and reproductive disorders. BPA is considered an endocrine disruptor, which means it can mimic hormones and create hormonal and gut imbalances. There are also concerns about the potential carcinogenic effects of BPA, although the evidence is not yet conclusive.
To address consumer concerns, Tupperware has taken steps to phase out the use of BPA in its products. As of March 2010, items sold by Tupperware in the US and Canada are made of BPA-free materials. Consumers who wish to reduce their exposure to BPA can opt for glass, porcelain, or stainless steel containers, especially for storing hot food or liquids. It is also recommended to avoid heating food in plastic containers, even those labelled as "microwave-safe," as the heat can cause toxins to leach into the food.
While the presence of BPA in Tupperware products has been a cause for concern, it is important to note that not all plastics contain BPA. Consumers can look for products with a resin code of 7 to identify BPA-containing plastics and choose alternatives. Additionally, the FDA continues to monitor and evaluate the safety of BPA in food packaging, working with other expert agencies to address any potential risks.

Tupperware's plastic is not safe to use in a microwave or dishwasher
Plastic is everywhere, and it has become a part of our daily lives. However, it is important to be cautious when using plastic products, especially when it comes to food storage and heating. While Tupperware products are considered safe, some of their food storage containers are made of polycarbonate (plastic #7), which can leach harmful chemicals into your food.
Tupperware's polycarbonate-based products, such as the Rock 'N Serve microwave line and the Meals-in-Minutes Microsteamer, are not recommended for microwave use. Even if a plastic container is labelled microwave-safe, it does not guarantee that it is safe from leaking toxins into your food. Heating food in plastic containers, especially in the microwave, can cause the plastic to leach chemicals such as Bisphenol A (BPA) and Bisphenol S (BPS) into your food. These chemicals have been linked to serious health issues, including hormonal and gut imbalances, reproductive disorders, and various types of cancer.
Additionally, it is advised to avoid using Tupperware containers in the dishwasher. Vintage Tupperware, especially those from the 1970s, may contain harmful substances such as lead, arsenic, mercury, and cadmium. These chemicals can leach into your food and pose a risk to your health. It is recommended to switch to safer materials for food storage, such as glass, ceramic, or stainless steel. Glass containers are now more accessible and affordable, with major manufacturers offering glass storage options.
To minimise your exposure to harmful chemicals, it is important to pay attention to the types of containers your food comes in contact with. Avoid storing warm or greasy foods in plastic containers, as this can increase the leaching of chemicals. Always opt for BPA-free and BPS-free containers to reduce your exposure to toxic substances.
While Tupperware has discontinued the use of BPA in their products since 2010, older Tupperware containers may still contain BPA. It is advisable to replace vintage or cloudy plastic containers with newer, safer alternatives. By taking these precautions, you can reduce your exposure to harmful chemicals and create a healthier and safer kitchen environment.
