Overall nutritional quality index

From Wikipedia, the free encyclopedia

The overall nutritional quality index was a nutritional rating system developed at the Yale-Griffin Prevention Research Center in 2008. A proprietary algorithm assigned foods a score between 1 and 100 intended to reflect the overall nutritional value a portion of the given food provided.[1] The system was marketed commercially as NuVal by NuVal, LLC, a joint venture with Topco Associates.[2] Over 1600 grocery stores in the United States placed NuVal scores on product shelf tags next to the price.[3][2] The commercial product was discontinued in 2017 amid accusations of conflicts of interest and criticism of NuVal LLC's refusal to publish the algorithm.[4] Either of which may have contributed to some inconsistencies in scoring where certain processed foods scored higher than, for instance, canned fruits and vegetables.[4]

Description

[edit]

The algorithm considers thirty nutrient factors, like the relative portions of vitamins, sugar, saturated fat, and trans fats and the quality of the protein and fat,[5] and produces a score from one to 100. Higher scores represent greater overall nutritional value. However, the actual algorithm, including the relative weights of the nutrients, was never disclosed to the public.[4]

Broccoli, blueberries, okra, oranges, and green beans were some foods that received the best score (100) while ice pops and soft drinks received the worst (1).[1]
