The<unk>  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<unk>  nutritional value a portion of the given food provided. The system was marketed commercially as NuVal by NuVal, LLC, a joint venture with Topco Associates. Over 1600 grocery stores in the United States placed NuVal scores on product shelf tags next to the price. The commercial product was discontinued in 2017 amid accusations of conflicts of interest and criticism of NuVal LLC's refusal to publish the algorithm. Either of which may have contributed to some inconsistencies in scoring where certain processed foods scored higher than, for instance, canned fruits and vegetables.
