Do PFAS chemicals raise cholesterol and blood lipid levels?

The link between your blood and your gear

PFAS chemicals raise cholesterol and blood lipid levels in your body. A 2026 study published in Env Sci Adv found that individuals with higher concentrations of these synthetic substances in their serum showed significant elevations in 24 different types of lipids, including triglycerides. Researchers analyzed 78 serum samples and confirmed that these chemicals are actively altering cellular membrane structures and energy storage pathways.

Why this matters for your home

The study focused on participants with a summed serum concentration of 7 PFAS (Σ7 PFAS) at or above 20 ng mL-1. This is the same threshold linked by the National Academies to increased risks of thyroid dysfunction and cancer. These chemicals are not just sitting in your products. They are leaching into your environment and accumulating in your blood, where they disrupt your metabolic health.

Take back control

You cannot avoid every synthetic chemical in the world, but you can stop bringing them into your home. Start by auditing your kitchen and living space for nonstick coatings, stain-resistant fabrics, and plastic food storage. Replacing these items is the most effective way to lower your daily exposure.
