Diet quality and health index checking list for the NHE assessment of foods.

Aim	Type of index	Most used	Additional information	How to include in LCA
Nutrient/food quantity	Nutrient profiling	Nutrient rich Index (NRF)	Adapt the DRI and MRV to the target population Include/exclude or weight nutrients depending on deficiencies Include graphical version for consumer (only in A2 indices) Include food groups and not only nutrients	To use as functional unit (all or only qualifying nutrients). Parallel assessment
Diet adequacy	Guidelines based indices	Healthy Eating index (HEI)	Adapt to country or population specific guidelines Include other aspects of lifestyle if possible	Parallel assessment
Diet diversity	Diversity based indices	Diet Diversity Score (DDS)	If possible, consider in and within food groups	Include in the biodiversity impact category? Parallel to biodiversity assessment
Nutrient quality	Nutrient quality indices	Depending on which nutrients are considered	If possible, consider interaction within the food matrix When data is available use in vitro bioavailability data	To use as functional unit Parallel assessment
Health	Consider the influence of dietary risk factors into health outcomes	Health Nutritional Index (HENI)	Adapt dietary risk factors to target country and population	Include in the health impact category Parallel assessment
