The Dietary Inflammatory Index (DII) is a numerical score that assesses a diet for its effect on several biomarkers linked to inflammation.
It had several drawbacks, such as being statistically biased, omitting the impact of flavonoids, and being reversed (scoring inflammatory diets as negative).
[3] This version quickly gained favor as a research tool for the study of diet-associated inflammation and health-related outcomes, and is the version commonly referred to as the DII.
[3] However, computing DII scores requires a nutrition database and normalizing dietary scores relative to the world standard food intake, and the original authors observed significant errors in the published literature.
The E-DII and C-DII require unique comparative databases which are products of Connecting Health Innovations and are not publicly available.
