Do PFAS in breastmilk mean formula is safer for newborns?
There is no evidence that formula is safer. Research shows that even the chemicals used to replace PFAS carry their own risks to health.
What's actually in it
The conversation about infant feeding is often clouded by the presence of PFAS (a group of man-made chemicals that do not break down) in our environment. While these chemicals have been found in breastmilk, switching to formula does not automatically remove the risk of chemical exposure. Manufacturers often use PFAS alternatives to create packaging and processing equipment for infant products.
These replacements are not necessarily safer. They are often just different chemicals that have not been studied as long as the ones they replaced. We are essentially trading one set of risks for another.
What the research says
A 2026 study in Chem Biol Interact looked at whether these new PFAS alternatives are actually safer than the originals. The peer-reviewed research found that these replacements carry comparable or novel risks for health issues, such as high blood pressure during pregnancy.
This science shows that moving away from one chemical does not guarantee a safer outcome. When you choose between feeding methods, you are navigating a system where chemical contamination is widespread in both breastmilk and industrial food production.
