Let’s talk plastic. It’s everywhere—from our food containers to water bottles, even in the lining of our tin cans. But there’s a hidden ingredient in many plastics that’s wreaking havoc on our health: BPA.
You might have heard of BPA (Bisphenol A) in passing, but many people don’t realise just how widespread and sneaky this chemical really is. As a naturopaths, we’ve seen firsthand how BPA exposure can silently undermine wellbeing—especially for women, children, and anyone dealing with hormonal imbalances, fatigue, or immune issues. The good news? Once you know where it’s hiding and how to avoid it, you can start taking back control.
So, What Is BPA?
BPA stands for Bisphenol A, a chemical used to harden plastics and prevent corrosion in metal. It’s been around since the 1960s and is still commonly found in polycarbonate plastics and epoxy resins.
But here’s the scary part: BPA is a known endocrine disruptor. That means it can mimic or interfere with the body’s natural hormones—especially estrogen. Even in tiny amounts, it can affect the body’s development, immune system, brain function, and reproductive health.
Where Is BPA Found?
BPA might not be listed on labels, but it’s in more places than you’d think. Common sources include:
- Plastic water bottles and takeaway containers
- Tinned foods (hiding in the resin lining inside cans)
- Receipts (thermal paper is often coated in BPA)
- Reusable food containers (especially older ones)
- Baby bottles and sippy cups (unless marked BPA-free)
- Tooth sealants and dental fillings
- Some feminine hygiene products and cosmetics packaging
Yes—it’s not just in the kitchen. Exposure can come through your skin, mouth, and even the air.
Why Should We Avoid BPA?
Even small, consistent exposure over time can lead to:
- Hormonal imbalances
- Thyroid dysfunction
- Fertility issues in both men and women
- Weight gain and insulin resistance
- Mood swings, anxiety, and brain fog
- Increased risk of certain cancers, like breast and prostate
- Disrupted immune function (especially relevant today!)
As naturopaths, we often treat women experiencing unexplained fatigue, weight changes, or irregular cycles—only to find out that hidden environmental toxins like BPA are playing a big role. It’s a silent stressor, and your body can only handle so much before symptoms begin to show.
Where Is BPA Still Lurking?
Even when a product is labelled “BPA-free,” don’t breathe easy just yet. Manufacturers often replace BPA with similar chemicals like BPS or BPF—and guess what? They’re also endocrine disruptors.
Watch out for:
- Microwaving plastic (even BPA-free plastics can leach chemicals when heated)
- Plastic-wrapped meat and cheese
- Coffee pods or plastic brewing systems
- Children’s toys made from polycarbonate
- Packaged or pre-cut fruits and veggies in clamshell containers
6 Easy Steps to Reduce Your BPA Exposure
You don’t need to overhaul your life overnight—but a few conscious swaps can make a big difference. Here’s where to start:
- Switch to glass or stainless steel
Store food in glass containers. Carry a stainless-steel water bottle. Choose stainless steel or glass lunch boxes over plastic ones. - Say no to receipts
If you don’t need it, don’t take it. Especially after using hand sanitiser (which makes BPA absorption worse). - Avoid canned foods when possible
Choose fresh, frozen, or jarred alternatives. If you do buy canned, look for brands that use BPA-free linings (but still double-check). - Don’t microwave plastic containers
Even if they say microwave-safe, heating plastic increases chemical leaching. Use ceramic or glass instead. - Limit plastic use with hot food or drinks
Don’t pour boiling liquids into plastic. Choose a French press or pour-over coffee method instead of pods or plastic brewers. - Choose natural personal care products
Not just for the ingredients inside, but for the packaging too. Choose brands that use glass, metal, or BPA-free materials.
What If I’ve Already Been Exposed?
Let’s be honest—most of us have had years of exposure already. But don’t panic. The body has amazing ways to heal, especially when supported naturally.
Here are some naturopathic tips to help your body detox:
- Support your liver: It’s your body’s detox hero. Eat cruciferous veggies (like broccoli, kale, and cabbage), drink dandelion or milk thistle tea, and stay hydrated.
- Eat more fibre: Fibre binds to toxins and helps eliminate them through your bowels. Aim for 30g per day through veggies, chia seeds, flaxseeds, and legumes.
- Sweat it out: Regular movement, infrared saunas, and even hot baths can help your body release stored chemicals through your skin.
- Get plenty of antioxidants: Berries, green tea, turmeric, and leafy greens help combat the oxidative stress BPA causes.
- Consider testing and tailored support: A naturopath can guide you through gentle detox protocols, hormone balancing, and restoring gut health.
Final Thoughts: Your Health Is Worth the Effort
We can’t live in a plastic bubble, but we can choose what we allow into our homes, onto our plates, and into our bodies. Reducing BPA exposure is one of the most empowering steps you can take for your long-term health, energy, and hormonal balance.
Small swaps lead to big change—and your body will thank you for it.
