Summary
This review introduces Computational Nutrition 2.0, a paradigm advancing beyond static, passive nutritional models toward closed-loop AI agentic systems. The authors describe how AI agents can enable dynamic personalised dietary intervention through digital twins, support causal inference via automated simulation, enable continuous disease risk monitoring through sensors, and optimise nutrition policy by generating trade-off portfolios. Whilst the vision is compelling, the authors acknowledge that realisation requires advances in agent technology, sensor reliability, and regulatory pathways.
Regional applicability
This is a methodological and conceptual framework paper with global relevance. The approaches described could support UK nutrition research and policy simulation, though implementation would require integration with UK-specific epidemiological data, food composition databases, and regulatory contexts (e.g. FSA, DHSC policy approval processes).
Key measures
Conceptual frameworks for: personalized metabolic response prediction; causal graph construction and counterfactual reasoning; continuous monitoring via non-invasive sensors; Pareto-optimal policy portfolios across health, environmental, economic, and equity dimensions.
Outcomes reported
The paper conceptualises how AI agents can advance personalized metabolic response prediction, causal inference in nutrition, disease risk monitoring, and nutrition policy simulation. It describes frameworks for closed-loop agentic systems including digital twins, nutritional causal agents, agent-driven perception systems, and multi-agent policy optimisation.
