• Theme: Structural determinants of hunger and inequality; agrarian change, uneven development, and distributional barriers shape hunger outcomes and policy effectiveness more than production alone [3], [8], [15], [17], [20].

• Theme: Ethical framing of policy responsibility in life‑and‑death nutrition decisions; US policy is treated as a governance test for social justice and biopolitical implications [5], [6], [17], [18].

• Theme: Nutrition science and dietary guidelines influence policy agendas and public health messaging; yet dietary knowledge interacts with political economy and distribution [7], [12], [13], [16].

• Theme: Food systems, supply chains, and agrarian structure underpin access and vulnerability; self-sufficiency, famine management, and deficit-country dynamics reveal system-level policy drivers [2], [4], [10], [15].

• Theme: Cultural practices, foodways, and behavioral nutrition dynamics shape and are reshaped by policy; dietary change, breastfeeding economics, and food habits illustrate human ecology in policy contexts [9], [10], [14], [19].
