- •
Many life cycle assessments of diets do not include all stages up to ingestion.
- •
Excluding life cycle stages beyond the farm generally underestimates diet impacts.
- •
Optimal system boundaries differ depending on food type and impact assessed.

We developed simplified methods for life cycle assessment of foods and diets.
- •
These methods allow a good trade-off between accuracy and data-collection cost.
