Risks of plastic food containers
Chemicals leaking into food
Plastic food containers like Tupperware are made from different types of plastic. Many of these plastics contain harmful chemicals like bisphenol A (BPA), bisphenol S (BPS), and phthalates. These chemicals can leak into the food stored in the containers, especially when exposed to heat or after long-term use. The leaking process increases as the plastic gets older, allowing more of these toxins to contaminate your food.
Tiny plastic particles in our food
In addition to chemical leaking, plastic containers can break down into tiny pieces called microplastics. These microscopic plastic particles can end up in your food, either from the containers themselves or from the environment. Ingesting microplastics can lead to various health issues, as these particles can accumulate in the body and potentially cause inflammation and cell damage.
Health problems linked to plastics
The chemicals and microplastics found in plastic food containers have been linked to several health concerns:
| Chemical | Potential Health Risks |
|---|---|
| BPA and BPS | – Hormonal imbalances |
| – Fertility issues | |
| – Increased risk of breast and prostate cancer | |
| Phthalates | – Reproductive problems |
| – Developmental issues in children | |
| – Other health concerns |
These chemicals can interfere with the body’s hormonal system, leading to various health problems. Microplastics can also cause inflammation and cell damage when ingested.
Scientific proof
Studies show plastics can harm health
Many studies have found links between exposure to chemicals from plastic and health issues:
- A 2020 study found that tiny plastic particles (microplastics) can disrupt gut bacteria, leading to inflammation, obesity, and diabetes.
- Researchers found that even small amounts of bisphenol S (BPS), a chemical used in some plastics, can interfere with normal cell functions and may contribute to asthma, birth defects, and cancer.
- A 2013 review analyzed 455 plastic products and found that almost all of them released hormone-disrupting chemicals. These chemicals can mimic or interfere with the body’s hormones, potentially causing reproductive problems, hormonal imbalances, and increased cancer risk (breast, prostate, etc.).
Microplastics found in human bodies
Recent research has detected microplastics in human tissues and fluids:
- A 2022 study found microplastics in human lungs for the first time, raising concerns about potential respiratory issues.
- Heart disease patients with microplastics in their arteries were twice as likely to have a heart attack, stroke, or die within 3 years.
- In a pilot study, microplastic particles were found in the heart tissue samples of 15 people undergoing heart surgeries.
- A 2022 study detected microplastics in nearly 80% of human blood samples analyzed, with PET being the most common type.
These findings suggest that microplastics can travel throughout the body and potentially accumulate in organs, raising concerns about their potential health impacts.
Better Options for Food Storage
Glass Containers
Glass containers are a safe choice for storing food. They do not release harmful chemicals into your food. Glass is also very strong and can handle high heat without breaking down. Many glass containers can go in the oven, microwave, and dishwasher, making them easy to use and clean.
Unlike plastic containers that can absorb smells and stains, glass containers stay fresh and clean. They are see-through, so you can easily find what’s inside. This helps reduce food waste by reminding you of leftovers that need to be eaten.
Stainless Steel Containers
Stainless steel is another safe and durable option for food storage. It does not corrode or leak chemicals into your food, even with acidic or salty items. Stainless steel containers are tough and won’t break or crack easily if dropped.
Many stainless steel containers have airtight lids and silicone seals, making them leakproof and great for carrying meals or storing liquids. They are usually dishwasher-safe, freezer-safe, and oven-safe (without the lid), making them versatile for various food storage needs.
Plant-Based Plastic Alternatives
If you prefer the convenience of plastic containers but want a safer and more eco-friendly option, consider plant-based or biodegradable plastics. These bioplastics are made from renewable sources like corn, sugarcane, or bamboo and are designed to break down naturally without leaving behind harmful microplastics.
While not as durable as glass or stainless steel, bioplastic containers are still a better choice than traditional plastics. Look for products labeled as compostable or biodegradable, and follow the manufacturer’s instructions for proper disposal.
