Calculations for NRFI scores:

The NRFI scores were calculated using NRFI 6.3 formula (Fulgoni et al., 2009), which includes 6 nutrients to encourage (protein, fiber, vitamins A, C, iron, and calcium) and 3 nutrients to limit (saturated fat, sodium, and added sugars). To calculate scores for illustrative purposes, IOM staff used the information available on the Nutrition Facts panel. As per the published algorithm, a reference value of 125 grams was used for total sugars because added sugars is not available on the Nutrition Facts panel; also protein was not adjusted for protein quality. NRFI scores can theoretically range from –300 to 900, but the majority of foods score in the –150 to 300 range. NRFI raw scores are often divided into quintiles and assigned a score 1–5 for simplicity. Raw scores are more precise for comparing foods and therefore those were used for our comparison tables.
