A closer look
Your blood is currently carrying a chemical payload that didn't exist a century ago. Per- and polyfluoroalkyl substances (PFAS), originally engineered for non-stick Teflon pans and waterproof jackets, feature unbreakable carbon-fluorine bonds. Environmental biomonitoring reveals these "forever chemicals" are now present in the blood serum of 97% of Americans. Because our livers lack the enzymes to break them down, PFAS molecules aggressively bind to albumin proteins in the bloodstream, bioaccumulating over decades to disrupt thyroid hormones and significantly elevate the risk of kidney cancer.
