It’s no secret that modern-day chemical pollution is reshaping the health of our planet—and our bodies. Known as “forever chemicals,” per- and polyfluoroalkyl substances (PFAS) are a growing concern for both environmental and human health. Their persistence in the environment and potential for bioaccumulation make them especially troubling. From your drinking water to everyday household products, PFAS have made their way into nearly every corner of our lives.
But what does this mean for your health? And how can you get proactive about minimizing your exposure? As a naturopathic doctor or holistic practitioner, understanding the risks of PFAS and how to support the body’s natural detoxification processes is key to protecting long-term health. Let’s take a closer look at the consequences of these toxins and how functional medicine can provide solutions.
What Are Forever Chemicals (PFAS)?
PFAS are a class of over 4,700 human-made compounds that are resistant to degradation thanks to their chemical stability. This durability has made PFAS useful in industries like firefighting, food packaging, textiles, cosmetics, and electronics. However, their chemical properties also mean they persist in the environment indefinitely—hence the name “forever chemicals.”
Alarmingly, a 2022 study by the U.S. Environmental Protection Agency (EPA) identified PFAS in drinking water as hazardous even in extremely small quantities. Studies have revealed that over 98% of U.S. adults have detectable levels of PFAS in their blood (Fenton SE et al., 2021). For natural health advocates, this raises serious concerns about the cumulative effects of long-term exposure.
How Forever Chemicals Affect Human Health
The pervasive nature of PFAS means they find their way into water supplies, food sources, and even products we use daily. Once absorbed by the body, PFAS can disrupt critical biological processes and contribute to numerous chronic health issues, including:
1. Liver Disease and Cancer
Significant associations have been made between high levels of PFAS exposure and liver damage. Long-chain variations of PFAS particularly increase the risk of nonalcoholic fatty liver disease (NAFLD) and hepatocellular carcinoma (HCC), a form of liver cancer. In one study, individuals with elevated PFAS levels faced a 4.5-fold greater risk of developing HCC (Goodrich JA et al., 2022).
2. Diabetes Risk
Emerging studies suggest a link between PFAS exposure and insulin resistance, which could elevate the risk for type 2 diabetes. A 2023 meta-analysis highlighted that individuals with higher PFAS levels had a significantly increased likelihood of developing type 2 diabetes (Gui SY et al., 2023), comparable to the risk associated with obesity.
3. Thyroid Dysfunction
PFAS can interfere with thyroid hormone regulation. Studies suggest disrupted T4 (thyroxine) levels can alter thyroid function (Kim MJ et al., 2018). For pregnant women, maternal PFAS levels can affect fetal thyroid hormone production, potentially leading to developmental concerns (Yang L et al., 2016).
4. Adverse Reproductive Outcomes
Studies show that PFAS exposure may contribute to low birth weight, preeclampsia, increased gestational diabetes, and other complications during pregnancy. As these chemicals readily pass through the placenta, they pose particular risks to developing fetuses (Gao X et al., 2021).
While the list of health impacts is long, the good news is that functional medicine and natural health strategies can provide tools to reduce exposure and support the body’s detoxification processes.
Reducing PFAS Exposure and Supporting Detoxification
Although avoiding PFAS entirely is nearly impossible due to their widespread presence, holistic practitioners and naturopathic medical doctors play an essential role in helping patients reduce their overall toxic load and build resilience against exposure. Here are several actionable steps:
1. Filter Your Drinking Water
Drinking water is one of the most common sources of PFAS exposure. The EPA recommends checking local water quality reports to determine contamination levels in your area. Opt for reverse osmosis filters or dual-stage carbon filters, both of which effectively remove most PFAS from drinking water (EPA, 2023).
2. Switch to Safer Products
Encourage patients to avoid consumer products that commonly contain PFAS, such as non-stick cookware, water-resistant clothing, or cosmetics with “fluoro” ingredients. The Green Science Policy Institute provides a helpful list of PFAS-free brands.
3. Choose a Clean Diet
Since PFAS contamination can accumulate in food, prioritize organic and local produce whenever possible. Evaluate local fish advisory reports to assess contamination levels in wild-caught fish and game (Naidu R et al., 2021).
4. Functional Medicine Detox Strategies
By focusing on the body’s natural detoxification pathways, functional medicine offers personalized strategies to alleviate the burden of PFAS and other toxins. Key approaches include:
- Supporting Glutathione Production: Use sulfur-rich foods (like broccoli and garlic) or supplements to boost glutathione, the body’s master antioxidant.
- Therapeutic Diets: High-fiber diets can bind and eliminate toxins through the digestive tract.
- Sweat It Out: Saunas, particularly infrared, can promote detoxification by encouraging toxin release through sweat.
- Hydration: A well-hydrated body maintains optimal kidney and liver function to break down pollutants like PFAS.
The Role of Functional Medicine and Holistic Care
When addressing PFAS exposure, a one-size-fits-all approach won’t suffice. Every individual’s response to environmental toxins is influenced by their genetics, age, current health status, and other factors. This is where a naturopathic doctor or holistic practitioner can shine by tailoring treatments based on the patient’s unique characteristics and environment.
Functional medicine emphasizes evaluating the total toxic load—an individual’s lifetime accumulation of exposures—and developing custom interventions to reduce that burden. Through personalized dietary, lifestyle, and detoxification strategies, functional medicine can empower individuals to heal from toxic stressors like PFAS.
Final Thoughts: Protecting Your Health in a Polluted World
PFAS may be here to stay, but with the right knowledge, you can minimize exposure and protect yourself from their harmful effects. Whether it’s swapping out household products, filtering your water, or incorporating functional detox strategies, small changes make a big difference over time.
If you’re concerned about how PFAS may be affecting your health, consult a naturopathic doctor or holistic practitioner. With their guidance, you can reduce your toxic load naturally, support your body’s ability to heal, and reclaim your vitality in today’s chemical-heavy world.
Key Takeaways:
- PFAS are persistent toxic chemicals linked to serious health conditions like liver disease, diabetes, and thyroid dysfunction.
- Major sources of exposure include contaminated drinking water, household products, and food supplies.
- Functional medicine and naturopathic care emphasize reducing total toxic load and promoting detoxification.
- Practical strategies include filtered water, clean diets, product swaps, and detox therapies like sauna use and glutathione support.
- Consult with a naturopathic doctor or holistic practitioner to create a personalized plan for mitigating toxins.
