Overall Nutritional Quality Index
The Overall Nutritional Quality Index is a nutritional rating system developed at the Yale-Griffin Prevention Research Center. It assigns foods a score between 1 and 100 to reflect the overall nutrition provided relative to the calories consumed.[1] The system has been marketed commercially as NuVal, and some consumer foods in the United States are marked with ONQI values as "NuVal".
Description
The ONQI for a food is the ratio of a "numerator" value representing beneficial nutrients such as iron, dietary fibre and vitamins,[2] and a "denominator" value representing detrimental nutrients such as cholesterol and saturated fat.
The following foods have the maximum ONQI of 100:[3] broccoli, blueberries, okra, oranges and green beans. Some of the lowest ONQIs are for white bread (9), hot dog (5), apple pie (2) and popsicle (1).
