Fig. 1: Histogram of changes (new–old) in the Food Compass Score (FCS) for 8,032 unique foods and beverages consumed in the United States (NHANES/FNDDS 2015–2016).

Scoring updates included (1) correction of attribute scoring for fruits and vegetables in the food-based ingredients domain to capture portions of fruits and vegetables in mixed dishes and recipes; and (2) revised methods for attribute scoring of NOVA categorization in the processing domain, based on manual classification rather than machine-learning classification. Overall FCS changes were modest, with most items (58%) having no more than a ± 5 point score change (out of 100), 41% having an increase of between 5–15 points, a few (1%) having a score increase of larger than 15 points, and a few (1%) having a decrease of larger than 5 points. The Spearman correlation between the new and old Food Compass Score was 0.98.
