PFAS never break down in the environment or body. They accumulate over a lifetime. By age 40, most North Americans have measurable PFAS in their bloodstream.
The read Glen’s take, in his words
PFAS chemicals don't leave. They accumulate in your body over a lifetime and they don't break down in the environment either. By age 40, most North Americans have measurable levels of PFAS in their bloodstream. That's not hypothetical — that's what biomonitoring studies show. We absorbed them through water, food packaging, cookware, and a thousand everyday products. This chapter is about what that means practically, and what you can actually do about it. Read it with curiosity, not despair. There are answers that make sense so let's explore them together and build a better future.
