GMOs have remained at the center of scientific and societal debate since their regulatory authorization and subsequent market introduction in the 1990 s. This review synthesizes epidemiological evidence from the literature, including observational studies and prior systematic reviews, alongside international policy frameworks, to evaluate potential associations between GMO exposure and human health. Current evidence does not support consistent causal links between GMO consumption and cancer, reproductive toxicity, allergies, or other chronic diseases. We systematically searched PubMed, Web of Science, and international health databases, applied predefined inclusion and exclusion criteria, and synthesized national-level epidemiological data using time-trend and Joinpoint regression analyses. Across countries and disease categories, no consistent temporal alignment was observed between GMO authorization and changes in disease incidence, and pooled breakpoint analyses showed heterogeneous patterns with estimates frequently overlapping zero. Overall, the findings provide no consistent epidemiological support for associations between GMO consumption and major chronic diseases.
