Economic Analysis of Dietary Choices and Health Outcomes

Economic analysis of dietary choices and health outcomes examines how the costs of foods influence individual and population health, and how diet‐related health burdens feed back into economic systems. Central to this field is the recognition that food prices, availability and consumer purchasing power shape dietary patterns, which in turn drive risks of non‐communicable diseases, undernutrition and health inequalities. Techniques range from microeconomic assessments of household food budgets and price-sensitivity to macroeconomic estimations of the true cost of food, incorporating healthcare expenditure and productivity losses. Researchers deploy cost-of-illness methods, true cost accounting frameworks and linear programming models to determine the minimal cost of nutritionally adequate diets and to quantify external health costs of dietary risk factors. Global analyses of relative caloric prices across income groups reveal systematic disparities in affordability between healthy and unhealthy foods, while country-specific studies of recommended‐diet affordability highlight barriers faced by low-income households. Together, these approaches inform policy levers such as subsidies, taxation, reformulation mandates and public procurement standards, aiming to realign market signals so that healthier choices become economically viable and health burdens are alleviated at scale.
