The Truth About BPA-Free Plastics (and What to Use Instead)
For years, BPA (bisphenol A) has been a buzzword in the health world—and for good reason. This chemical, commonly found in plastic containers, water bottles, and the lining of canned goods, is a known endocrine disruptor. It can mimic hormones like estrogen in the body, potentially leading to reproductive issues, developmental delays in children, and even an increased risk of certain cancers.
But is “BPA-free” plastic really a safer option? It’s not as clear-cut as marketing claims would have you believe. In this post, we’ll dive into the dangers of BPA, the truth about BPA substitutes, and how to transition to safer, non-toxic alternatives.
What is BPA and Why is it Harmful?
BPA is a synthetic chemical used to harden plastics and create epoxy resins. It’s found in:
Water bottles and food storage containers.
The inner lining of canned foods and beverages.
Thermal paper receipts (yes, even handling these can expose you to BPA!).
BPA is an endocrine disruptor, meaning it interferes with hormone function. Studies link BPA exposure to:
Hormonal imbalances (e.g., estrogen mimicking).
Infertility and reproductive health issues.
Behavioral problems and developmental delays in children.
Increased risk of certain cancers, such as breast and prostate cancer.
The problem is compounded by how BPA can leach into food and drinks, particularly when plastics are heated, scratched, or exposed to acidic or fatty foods.
The Problem with BPA-Free Plastics
When the health risks of BPA gained widespread attention, manufacturers began touting “BPA-free” products as safer alternatives. However, many of these replacements—such as BPS (bisphenol S) and BPF (bisphenol F)—are chemically similar to BPA and may carry the same or even worse risks.
What we know about BPA substitutes:
Studies show that BPS and BPF also disrupt hormone activity and can mimic estrogen just like BPA.
BPS is often less biodegradable than BPA, potentially increasing its environmental impact.
BPA-free doesn’t mean risk-free—it’s a marketing tactic to appeal to consumers without addressing the root problem: the safety of all bisphenols.
How to Avoid BPA and Its Substitutes
The best way to protect yourself and your family from BPA, BPS, and other harmful chemicals is to transition to safer materials and practices.
1. Swap Plastic for Glass or Stainless Steel
Why?
Glass and stainless steel are inert, meaning they won’t leach chemicals into your food or drinks.
What to Do:
Store leftovers in glass containers with silicone or stainless steel lids.
Use stainless steel or glass water bottles instead of plastic ones.
Instead of plastic cooking utensils, choose solid wood, bamboo, or stainless steel
2. Choose Fresh or Frozen Over Canned Foods
Why?
The linings of most canned goods contain BPA or its substitutes.
What to Do:
Opt for fresh or frozen produce instead of canned. Frozen vegetables are often less expensive and more nutritious than fresh, as they’re frozen sooner after harvesting.
If you need canned goods, look for brands that explicitly state “BPA-free linings” and verify their materials.
3. Avoid Heating Plastic
Why?
Heat accelerates the leaching of chemicals into food.
What to Do:
Never microwave food in plastic containers or use plastic wrap on hot food.
Bring your own stainless steel or glass mug on your next Starbucks run. (You'll get a discount, too!)
Avoid sous-vide cooking and plastic slow cooker liners.
Use glass or ceramic for reheating.
4. Say No to Thermal Paper Receipts
Why?
Receipts are often coated in BPA, which can transfer to your skin.
What to Do:
Opt for email receipts whenever possible.
Wash your hands after handling receipts, and avoid letting children touch them.
Safer Alternatives for Everyday Use
Here are some practical swaps to help you phase out BPA and other harmful chemicals.
A Balanced Approach
Reducing BPA exposure doesn’t have to mean throwing away every plastic item in your home overnight. Start small and focus on the most impactful changes, like switching your most-used plastic containers to glass food storage, or choosing frozen produce over canned. Every step you take toward a safer, non-toxic kitchen is a win for your family’s health.
