Moderate Toxins · Brain health technique
Minimize exposure to persistent organic pollutants (POPs / “forever chemicals”)
Evidence grade: Experimental
Long-lasting synthetic compounds that build up in the environment and body fat. They include per- and polyfluoroalkyl substances (PFAS) found in non-stick cookware, stain-resistant fabrics, and fast-food wrappers; polychlorinated biphenyls (PCBs) in old electrical equipment; dioxins; and certain flame retardants and pesticides. These chemicals persist for decades and interfere with hormones and metabolism.

How to practice Minimize exposure to persistent organic pollutants (POPs / “forever chemicals”)
Hard to avoid completely; effects are cumulative and lifelong. Risk likely scales with total body burden, which is higher in people with long-term occupational or dietary exposure. Regular blood or plasma donations can help reduce levels.
The evidence behind Minimize exposure to persistent organic pollutants (POPs / “forever chemicals”)
These fat-soluble compounds accumulate in brain and fat tissue, altering hormones and immune signaling. Human studies connect higher PFAS and PCB blood levels with slower processing speed and greater cognitive decline; animal data show amyloid and tau increases. Still, direct dementia outcomes are limited.
