The Open Nutrient Density Index is a science-based scoring system that evaluates the nutrient density of food products.
And it’s FREE to all qualified retailers.
ONDI actually identifies nutrient-rich, healthier foods in line with USDA guidelines. Developed by Sifter, it's designed for easy use by retailers in-store and online.
Sifter's intelligent digital platform powers solutions that help people find the foods that are right for them.
ONDI activates this science-based scoring system that ranks foods based on nutrient density.
Specifically how rich they are in beneficial nutrients (like vitamins, minerals, and protein) relative to calories and low in nutrients of concern (like added sugars, sodium, and saturated fat).
Simple. Effective. Flexible.
ONDI results are normalized on a 0–100 scale, making it easy to:
Benchmark nutrient density across categories
Compare against competitive items
Integrate into consumer-facing platforms and health claims
ONDI uses a two-part rule to assess items with fewer than 10 calories:
- Must qualify as FDA “Healthy” = Yes
- Ingredient list must be free of the following exclusions:
Products that meet the FDA’s “Healthy” criteria receive a scoring advantage in ONDI. This approach:
If a product meets all of the following:
Then the product is excluded from ONDI scoring.
