Prenatal Dietary Exposure to Endocrine Disruptors and Its Lasting Impact on Offspring Health

Environmental stressors during the crucial period of fetal development can have a substantial impact on long-term health outcomes. A major concern is dietary exposure to endocrine-disrupting chemicals (EDCs), which can readily cross the placenta and disrupt fetal hormonal signaling and developmental programming. Examples of these chemicals include bisphenols, phthalates, pesticides, and persistent organic pollutants (POPs). Prenatal exposure to EDC has been associated with long-term effects in children, including immune disruption, metabolic dysregulation, impaired neurodevelopment, and reproductive alterations, as evidenced by human cohort studies and experimental models. Epigenetic reprogramming, direct interference with endocrine signaling, and oxidative stress (OS) are hypothesized pathways for these adverse consequences, which often combine to produce long-lasting physiological changes. This narrative review summarizes current research on maternal dietary exposure to EDCs during pregnancy, highlighting associations with adverse child health outcomes. It also discusses the growing evidence of transgenerational effects, the potential mechanisms linking prenatal exposure to long-term outcomes, and the importance of understanding the roles of timing, dosage, and chemical type. By highlighting the necessity of focused interventions to lower maternal EDC exposure and lessen threats to the health of offspring, the review concludes by discussing implications for future research, preventive measures, and public health policy.
