Can PFAS and phthalates in your body be linked to kidney problems?
Some concern. A 2026 U.S. study links measured PFAS and phthalate markers with lower kidney filtration, but it does not prove one product causes kidney disease.
What's actually in it
PFAS are used in some stain-resistant, water-resistant, nonstick, and grease-resistant products. Phthalates are used in some plastics, vinyl, fragrances, and packaging. These chemicals can reach people through food contact, dust, air, and products used at home.
What the research says
A 2026 Food Chem Toxicol study used NHANES 2013-2018 data from U.S. adults. The study found that one PFAS marker, MPAH, was linked with higher odds of low eGFR. Several phthalate metabolites were also linked with low eGFR. eGFR is a common measure of how well kidneys filter blood.
This study does not prove that one pan, package, or bottle caused kidney disease. It does show that higher measured exposure to some PFAS and phthalate markers traveled with lower kidney filtration in this population.
What you can do
Keep the simple wins. Use glass storage for leftovers, avoid heating food in plastic, pick fragrance-free products, and use a water filter if PFAS are a local concern. These steps lower avoidable contact without panic.

What to use instead
Use glass storage to cut down on plastic food contact for leftovers and pantry staples.
