In view of the increasing concerns over chemical exposure during pregnancy on adverse health effects in the child, RCOG has published this opinion paper to offer advice for women to reduce overall chemical exposure.

Summary of RCOG's recommendations on reducing chemical exposure in pregnant women:

  • Food consumption:
    • Reduce heavy metals exposure – Avoid over-consumption of oily fish by limiting to once per week.
    • Reduce non-food chemicals exposure – Eat fresh foods rather than processed foods whenever possible; reduce the use of cans or plastic containers for consumption or food storage.
  • Intake of dietary supplement or over-the-counter medicines:
    • Be aware of herbal or alternative "natural" products that do not indicate as safe for use during pregnancy.
    • Only take over-the-counter painkillers when necessary and with the advice of your doctor.
  • Other lifestyle modifications:
    • Minimize the use of personal care products (e.g. cosmetics) and household chemicals (e.g. household pesticides).
    • Avoid paint fumes and minimize the exposure to newly produced furniture.
