PFAS – often called “forever chemicals” – have recently been in the headlines again, especially following the latest BBC Panorama investigation, which highlighted how widespread these substances are in our environment and how difficult they are to avoid.
The programme revealed that PFAS are being found in UK water sources, food packaging, cosmetics, household items and even the air we breathe. Understandably, many people are now asking what PFAS actually are, whether they pose a risk, and what they can do to reduce their exposure.
This blog breaks it down in simple terms and explains how we can help.
What Are PFAS?
PFAS (per- and polyfluoroalkyl substances) are a family of more than 10,000 man-made chemicals used since the 1950s to make products resistant to water, heat, oil and stains.
They’re found in:
-
Non-stick cookware
-
Waterproof clothing
-
Food packaging (especially grease-proof wrappers)
-
Certain cosmetics
-
Stain-resistant carpets and furnishings
-
Firefighting foams
-
Cleaning products
They are known as “forever chemicals” because they do not break down easily and can persist in the environment – and in our bodies – for decades.
Why Are PFAS a Concern?
Research suggests that long-term exposure to certain PFAS may be associated with:
-
Hormonal disruption
-
Immune system effects
-
Thyroid disease
-
Elevated cholesterol
-
Reduced fertility
-
Certain cancers (e.g., kidney and testicular)
-
Pregnancy and developmental issues
The BBC Panorama report highlighted concerns that UK regulations may not yet fully reflect the emerging evidence, and that levels in some water sources are higher than expected.
Although more research is needed, particularly on low-level chronic exposure, the growing scientific consensus is that reducing PFAS exposure is sensible wherever possible.
How Do PFAS Enter the Body?
Most people are exposed through:
-
Drinking water
-
Food packaging
-
Dust in the home (from treated fabrics or carpeting)
-
Cosmetics and personal care products
-
Non-stick cookware when damaged or overheated
Because these chemicals accumulate, even small, repeated exposures can add up over time.
How Can You Reduce Your PFAS Exposure?
Here are practical steps that can make a meaningful difference:
✔ Choose PFAS-free cookware
Opt for stainless steel, cast iron, or ceramic instead of damaged non-stick pans.
✔ Limit takeaway packaging
Greaseproof packaging often contains PFAS – cooking at home reduces exposure.
✔ Check your cosmetics
Avoid products containing ingredients ending in “-fluoro” or “PTFE”.
✔ Improve your indoor air quality
Regular vacuuming (ideally with a HEPA filter) helps reduce contaminated dust.
✔ Use a high-quality water filter
Some filters can reduce PFAS – look for certified PFAS reduction.
Can You Test for PFAS?
Blood tests for PFAS do exist, but they are not yet widely available in the UK, and most NHS services currently do not offer PFAS screening.
We are actively exploring partnerships with accredited laboratories so we can offer PFAS testing to our patients soon.
➡ PFAS screening coming to our clinic shortly – updates to follow.
This will help patients who are particularly concerned about exposure, have symptoms they wish to discuss, or want a clearer picture of their environmental health risks.
When Should You Seek Medical Advice?
If you are:
-
Concerned about long-term exposure
-
Experiencing symptoms such as thyroid issues, unexplained fatigue, high cholesterol, or hormonal changes
-
Pregnant or planning pregnancy
-
Living in an area highlighted in media reports
-
Interested in environmental health screening
…it may be worth booking a consultation.
Final Thoughts
PFAS are a complex environmental and public health issue, and the recent BBC Panorama report has rightly drawn attention to how widespread these chemicals are. While complete avoidance is impossible, knowledge and small lifestyle changes can significantly reduce your exposure.
If you’re worried about PFAS, your diet, or your overall health risks, our doctors are here to help you make sense of the evidence and support you with practical, personalised guidance.
📅 If you’re concerned about chemical exposure, diet, or metabolic health, book a health screen with our team. We’re here to help you take proactive steps towards better long-term health.
