Reversing the Burden of Proof in Food Safety: The Precautionary Principle Applied to Human Nutrition

A. C. Applebee, L. N. Combe · 2026

Abstract

The modern food supply operates under an inverted burden of proof: substances are permitted in food until demonstrated harmful, rather than excluded until demonstrated safe. This paper argues that this inversion is ethically indefensible, scientifically unjustifiable, and causally linked to the epidemic-scale chronic disease burden of industrialized populations. Drawing on cross-cultural epidemiological evidence from traditional populations — including the Kitava study (n=1,200; zero acne, near-zero cardiovascular disease, diabetes, and cancer), Okinawan longevity data, Inuit disease profiles, and the Wai population — we demonstrate that Homo sapiens consuming species-appropriate diets do not develop the diseases currently treated as inevitable features of human aging. These populations are not genetically privileged; when they adopt Western diets, Western disease rates emerge within a single generation. The paper examines the regulatory capture of food safety agencies (FDA, FSANZ, EFSA) through industry self-certification mechanisms such as the United States GRAS (Generally Recognized As Safe) framework, the role of Advanced Glycation End-products (AGEs) as a specific mechanistic pathway linking processed food to chronic disease, and the function of marketing as the mechanism by which industrial food production determines human diet.
