How harmful is BPA / BPS / BPF (bisphenols)?

BPA / BPS / BPF (bisphenols) is rated MODERATE avoidance priority (4.7/10) on the Read Off Label scale, derived from moderate evidence of med harm magnitude and low-moderate chronic exposure prevalence.

Bottom line

Read Off Label rates BPA / BPS / BPF (bisphenols) a MODERATE avoidance priority (4.7/10) based on moderate evidence of med harm magnitude and low-moderate chronic exposure prevalence.

EFSA 2023 TDI reduction of 20,000-fold is one of the most dramatic regulatory changes in chemical risk assessment.

The intervention here is reducing exposure, not adding a compound.

What this is

EFSA 2023 TDI reduction of 20,000-fold is one of the most dramatic regulatory changes in chemical risk assessment. FDA largely disagrees with EFSA's assessment. BPS/BPF replacements show similar endocrine activity in vitro — don't assume 'BPA-free' = 'safe'. Thermal receipts deliver detectable BPA through skin.

Mechanism

Bisphenol A (polycarbonate plastics, epoxy can linings, thermal paper receipts); weak estrogen receptor agonist; 'BPA-free' often means BPS/BPF — structurally similar, likely similar concerns ('regrettable substitution')

Dose & route

Glass/stainless; BPA-free cans (Eden, Muir Glen, some Amy's); don't microwave plastics; limit thermal receipt handling
