What You Need to Know About Plastic Tupperware and Endocrine Disrupting Chemicals

In today’s fast-paced world, plastic containers like Tupperware are household essentials. They provide convenience for food storage, are easy to transport, and are often dishwasher safe. However, hidden beneath these benefits is a pressing concern: endocrine disrupting chemicals (EDCs). Understanding these chemicals and their implications can help you better protect your health.


Understanding Endocrine Disrupting Chemicals


Endocrine disrupting chemicals are substances that can interfere with your body's hormonal system. They are capable of mimicking or blocking hormones, which can lead to various health problems, including reproductive issues and metabolic disorders. A study by the Endocrine Society found that exposure to EDCs increases the risk of obesity and diabetes, substances we encounter daily in the form of plastics, pesticides, and personal care products.


In food storage, these chemicals can leach into what we eat. The most notorious in relation to Tupperware is Bisphenol A (BPA). Research shows that nearly 90% of Americans have BPA in their urine, indicating widespread exposure. Other harmful substances, such as phthalates, are also found in some plastic containers and can disrupt endocrine functions, leading to long-term health consequences.


The Connection Between Tupperware and EDCs


Many types of plastic Tupperware contain chemicals that can leach into food, particularly when heated. BPA is a common ingredient in polycarbonate plastics and epoxy resins, valued for their durability and heat resistance.


In response to health concerns, many manufacturers now market Tupperware as “BPA-free.” However, simply avoiding BPA does not guarantee a product is safe. Alternatives such as BPS (Bisphenol S) and BPF (Bisphenol F) can have similar hormonal disruption effects. A study published in the journal Environmental Health Perspectives found that BPS can be just as harmful, raising concerns about the safety of BPA-free products.

How Chemicals Leach from Tupperware


Leaching occurs when harmful substances migrate from plastic containers into food. Several factors can heighten this risk:


  • Temperature: Heating food in plastic, especially in a microwave, can increase the transfer of chemicals. For instance, a study found that microwaving food in plastic led to a 55% increase in BPA levels in food.

  • Time: Longer food storage in plastic increases leaching likelihood. Keeping food in plastic for weeks can allow more chemicals to seep into your meals.

  • Fat Content: Fatty foods can absorb more chemicals compared to leaner foods. For example, a high-fat food like cheese can carry more harmful chemicals from plastic.

  • Type of Plastic: Certain plastics are more prone to leaching. For example, plastics labeled with recycling codes 3 (polyvinyl chloride) and 6 (polystyrene) are more likely to leach chemicals into food.


Understanding these factors empowers consumers to make safer choices about food storage.


Safe Practices for Using Tupperware


To reduce exposure to endocrine disrupting chemicals in plastic Tupperware, consider these practical steps:


  1. Choose Glass, Stainless Steel or Silicone: Where possible, opt for glass, stainless steel or silicone containers, as they are free from harmful chemicals and withstand higher temperatures without leaching.

  2. Avoid Heating in Plastic: Skip the microwave when using plastic containers. Instead, use glass or ceramic to heat meals.

  3. Check for Recycling Codes: Familiarize yourself with recycling codes on plastic containers. Those marked with codes 1, 2, and 4 generally pose fewer risks. Avoid products labeled with codes 3, 6, and certain 7s, which may contain BPA or related compounds.

  4. Inspect Your Containers: Regularly examine your Tupperware for signs of wear or damage. If a container is scratched or discolored, discard it.

  5. Avoid Long-term Storage: Limit the time food spends in plastic, especially if it is fatty or acidic.


Regulatory Landscape and Consumer Awareness


Regulations surrounding chemicals in food contact materials are changing. Various health organizations and governments are making strides to limit harmful substances in plastics. However, the onus is also on consumers to stay informed.


Awareness is key. Advocacy groups are pushing for clearer ingredient listings for food containers and stricter regulation of EDCs. Take time to educate yourself about the potential risks and practices that can mitigate those risks.


Making Informed Choices for a Safer Kitchen


Though Tupperware and similar plastic containers offer seamless convenience, staying informed about potential health risks is vital. By making mindful choices and using safer materials whenever possible, you can help protect your health and that of your family from harmful chemicals.


Knowledge is the first step towards a healthier lifestyle. By being proactive in understanding the materials that come into contact with your food, you can create a safer kitchen environment. Keep these considerations in mind as you organise and store your meals, ensuring that your food preparation remains as healthy as possible.
