Datasets and codes for “From Meat to Legumes: Integrated Life Cycle and Health Burden Assessment Reveals Environmental Co-benefits and Nutritional Trade-offs in China’s Dietary Transition”

This record contains the R code used for the age-stratified dietary-risk-function calculations and the aggregation of dietary-risk contributions for the Health Nutritional Index (HENI) analysis. The code requires prepared input objects derived from the CHNS data and parameter sources described in the manuscript. Aggregate coefficients and scenario-level results are reported in the Supplementary Information.
