Validating nutrient selection for product-group-specific nutrient indices for use as functional units in life cycle assessment of foods.

ABSTRACT: The ability to provide adequate nutrition is considered a key factor in evaluating the sustainability of foods and diets. Nutrient indices are used as functional units (FU) in life cycle assessment of foods to include nutritional performance in the environmental assessment of a product. Several general and food-group-specific nutrient indices exist but many lack validation, particularly when used as FU. In addition, the nutrient selection strategies and reference units for nutrient intake can vary considerably among studies. To validate intake-based product-group-specific nutrient indices previously developed for protein (NR-FI_prot) and carbohydrate (NR-FI_carb) foods and for fruits and vegetables (NR-FI_veg), we applied principal component analysis to invest
