Can BPA analogs in children's food containers lower their IQ?

What's actually in it

"BPA-free" water bottles, sippy cups, and food containers use replacement chemicals like bisphenol S (BPS), bisphenol F (BPF), and bisphenol AF (BPAF). These analogs serve the same function as BPA but were assumed to be safer. Children ingest them through food and drinks stored in plastic containers daily.

Children's developing brains are more vulnerable to endocrine disruptors than adult brains. The neural connections forming between ages 2 and 6 are highly sensitive to hormonal interference.

What the research says

A 2025 prospective cohort study in Environ Res measured bisphenol analog levels in 4-year-old children and then tested their IQ at age 6. Children with higher BPA analog exposure had lower intelligence quotient scores two years later.

The association held after controlling for parental education, family income, and other factors known to influence IQ. The study looked at multiple bisphenol types and found that BPS and BPF showed the strongest negative associations with cognitive scores.

Two IQ points may not sound like much for one child, but across a population, it's a meaningful shift. The study adds to growing evidence that BPA replacements are not the safe alternatives the plastics industry claimed. Glass and stainless steel containers for children's food and drinks eliminate bisphenol exposure entirely.
