The Open Health Score IndexTM is a clear, evidence-based scoring system built to help consumers understand the healthfulness of food products. It evaluates each product across three important areas:
Nutrient Density + FDA Healthy - Ingredient Concerns
OHSI measures nutrient density by balancing beneficial nutrients (like fiber, vitamins, and minerals) against limiting ones (like sodium, added sugar, and saturated fat). Non-food and specialty items—such as alcohol, baby food, and supplements—are excluded. All scores are normalized on a 0–100 scale for easy comparison.
Sifter's intelligent digital platform powers solutions that help people find the foods that are right for them.
OHSI activates the ability of the Nutrient Rich Food Index (NRFI), a science-based scoring system that ranks foods by nutrient density, to power effective product scoring.
The FDA’s updated “Healthy” definition is then factored in, which emphasizes nutrient-rich foods and key food groups that support long-term health, moving beyond the old focus on just limiting fat and sodium.
Simple. Effective. Flexible.
OHSI 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
OHSI helps shoppers make healthier food choices by highlighting nutrient-dense products that support overall wellness. It simplifies complex nutrition science into clear, actionable guidance at the point of purchase—whether online or in-store—empowering consumers to improve their diets and reduce the risk of chronic diseases.
The Nutrient Rich Food Index was developed by Dr. Adam Drewnowski, a leading public health nutrition expert at the University of Washington. It’s rooted in peer-reviewed research and aligns with federal nutrition guidance, making it a credible and effective tool for product evaluation. More about NRFI.
The revised FDA “Healthy” claim reflects modern nutrition science and promotes nutrient-rich, food group–based eating. Unlike the old standard, which focused mostly on limiting fat and sodium, the new definition emphasizes foods that include key food groups aligned with USDA MyPlate, aiming to support long-term health and prevent chronic disease.

Retailers integrate OHSI into their own unique programs using digital shelf tags, in-store signage, e-commerce platforms, and nutrition programs. These tools provide clear guidance to help their shoppers quickly identify products that align with healthy eating patterns.
