Historical Famine, Epigenetic Programming, and Modern Gluten Exposure: A Testable Hypothesis for Celiac Disease

This manuscript presents a testable hypothesis concerning the potential relationship between historical famine, developmental and epigenetic programming, nutritional transition, and modern gluten exposure in celiac disease. The proposed framework suggests that nutritional stress during prenatal and early-life development may have lasting biological effects that could interact with genetic susceptibility and subsequent gluten exposure. Evidence from human famine cohorts has demonstrated persistent epigenetic differences associated with prenatal famine exposure, while epidemiological studies have reported geographic variation in celiac disease prevalence and associations between wheat or gluten availability and celiac disease. This work is presented as a hypothesis and research proposal rather than as evidence of an established causal relationship. The proposed mechanisms require validation through epidemiological, genetic, and epigenetic studies. Keywords: celiac disease; gluten; historical famine; epigenetics; DNA methylation; prenatal nutrition; nutritional transition; HLA-DQ2; HLA-DQ8.
