Summary:
- New research indicates that exposure to mixtures of per- and polyfluoroalkyl substances (PFAS)—often referred to as "forever chemicals"—is significantly associated with increased body mass index and higher obesity risk in children.
- The study highlights the limitations of traditional toxicology, which often assesses chemicals individually, by demonstrating that synergistic interactions between multiple endocrine-disrupting chemicals can exacerbate metabolic health risks.
