Eco-Nutrition: Systems Diversity and Sustainable Diets

This article explores Eco-Nutrition: Systems Diversity and Sustainable Diets as a bridge between ecological resilience and human nourishment. It draws on three principal sources—the 22nd annual Harvard Nutrition Obesity Symposium, the Alliance of Bioversity International & CIAT’s submission to the Convention on Biological Diversity, and the WHO–CBD State of Knowledge Review—to examine how food systems, biodiversity, and nutrition are interconnected. The narrative unfolds across acts and mirrors: uncovering the hidden hunger of homogeneity, situating food systems at the crossroads of climate change and inequity, and showing how ecological and dietary diversity sustain one another through functional roles and pollinator networks. Ancient wisdom, such as the “three sisters,” is contrasted with modern challenges like hidden hunger and pollinator decline. Through science, philosophy, and story, the article argues that eco-nutrition is not merely diet diversity but a worldview of interdependence. It closes with a reflection that diversity—ecological, nutritional, cultural, and systemic—is not a luxury but the quiet architecture of survival.
