Data Sheet 1_Climate and nutritional implications of Thai curry-over-rice menus: a recipe-level assessment of carbon footprints and dietary quality.pdf

Ingredient acquisition served as the primary environmental hotspot, accounting for 86% of emissions in animal-protein menus and 69% in non-animal-protein menus. A normalized heatmap analysis linking GHG emissions to 22 nutritional indicators revealed critical trade-offs between nutritional yields and carbon investments. Fish-based menus demonstrated superior climate efficiency, outperforming chicken and pork in emissions-normalized macronutrient yields.

Menus centered on rice and noodles optimized caloric and carbohydrate yields relative to carbon emissions. Vegetable menus were highly effective at providing minerals and vitamins while minimizing environmental impact. These quantitative insights suggest that adjusting both the type and portion size of animal protein constitutes a significant leverage point for developing climate-friendly dishes.

Additionally, these findings support implementing targeted behavioral interventions to promote climate- and health-conscious dietary choices, such as introducing dual carbon and nutrition labeling to assist consumers in self-regulation.</p>
