Animal studies have linked obesity and other health problems with exposure to bisphenol A (BPA). That’s a common ingredient of many clear, hard plastics and the resins that line food cans. Concerns over BPA health impacts led manufacturers to start phasing out the chemical in products that make contact with foods and drinks. Now a study in children and teens suggests that even some BPA substitutes may foster weight gain.
Those substitutes — BPS (bisphenol S) and BPF (bisphenol F) — are now used as a lining in some aluminum food cans. They’re also found in the paper used to print cash-register receipts.
Melanie Jacobson works in New York City at the New York University School of Medicine. Her team’s new study finds that overweight kids tend to have higher levels of BPS and BPF in their bodies than do normal-weight kids. That would suggest that like BPA, these chemicals are obesogens (Oh-BE-suh-genz).
