Plastic and cardboard packaging: Here's how to protect yourself from hidden carcinogens

Everyday exposure to plastic food containers, water bottles, and even cosmetic packaging allows harmful chemicals to gradually accumulate in the body. Over time, this accumulation can contribute to the proliferation of hormone-sensitive cells, multiplying the risk of breast cancer (Image credit: Unsplash)

From food containers and water bottles to cosmetics and household goods, plastic and cardboard materials offer convenience. It is nearly impossible to go through a day without encountering plastic or cardboard packaging. However, beneath their ease and practicality lies a hidden threat to your health. The chemicals found in these materials, particularly plastics, have been linked to serious health concerns, including breast cancer.

Plastic and cardboard packaging contain chemicals such as BPA (Bisphenol A) and phthalates, which can disrupt the body's hormone levels, warns Dr Rohan Khandelwal, Lead Consultant and Head of the Breast Centre at CK Birla Hospital, Gurugram. "BPA and phthalates mimic estrogen in the body, and this can interfere with the natural balance of hormones. Some breast cancers are hormone-sensitive, meaning their growth is fueled by hormones like estrogen. Exposure to these chemicals can potentially increase the risk of developing such cancers," Dr Khandelwal adds.

In addition to BPA and phthalates, another harmful chemical commonly found in plastics is vinyl chloride, a known carcinogen. Everyday exposure to plastic food containers, water bottles, and even cosmetic packaging allows these chemicals to gradually accumulate in the body. Over time, this accumulation can contribute to the proliferation of hormone-sensitive cells, multiplying the risk of breast cancer.

How to reduce the risk:

While it may be difficult to completely eliminate plastic from your life, Dr Khandelwal suggests some practical steps you can take to reduce your exposure to harmful chemicals:

• Store foods in glass or stainless steel containers: These materials are safer alternatives to plastic and do not leach harmful chemicals into your food.

• Avoid heating food in plastic containers: Heating plastic can cause chemicals to leach into your food, especially in the microwave. Opt for glass or ceramic dishes instead.

• Choose fresh or frozen foods over canned goods: Many canned foods have plastic linings that contain harmful chemicals like BPA. Fresh or frozen options are safer alternatives.

• Use glass or stainless steel water bottles: Plastic bottles can release harmful chemicals, especially when exposed to heat. Switch to reusable glass or stainless steel bottles for a healthier choice.

• Steer clear of plastics labeled with recycling codes 3, 6, and 7: These plastics are more likely to contain BPA and phthalates. Opt for safer alternatives whenever possible.

• Opt for natural or organic cosmetics: Choose products that come in non-plastic packaging to reduce your exposure to harmful chemicals.

• Use paper wraps instead of plastic wraps: When storing food, paper wraps are a safer alternative to plastic.

• Filter your tap water: A good water filter can help reduce your intake of microplastics and other contaminants.

• Cut back on single-use plastics: Avoid plastic straws, utensils, and shopping bags. Even small changes can make a significant impact on your health and the environment.

• Adopt recycling practices: By recycling responsibly, you can help reduce the amount of plastic waste that ends up in the environment, further limiting exposure to harmful chemicals.

Dr Khandelwal says that even small adjustments can make a big difference over time. "Plastics are so embedded in our daily lives that reducing exposure to harmful chemicals can feel overwhelming. But by making simple changes, such as switching to glass containers or filtering your water, you can significantly lower your risk of health issues like breast cancer. It's about minimising the cumulative intake of carcinogens over time," he says.
