What the Data Says About
udon by Nasoya carries a composite safety score of 95/100, which we classify as "Safe" on our four-tier shelf-label framework. The score is computed by mapping each labeled ingredient against FDA Substances Added to Food (SAFFA) regulatory status and CSPI Chemical Cuisine classifications, then penalizing the overall product for each additive rated as caution-or-worse. Product data originates from the OpenFoodFacts collaborative catalog; safety annotations come from federal regulators and the Center for Science in the Public Interest.
Our scan identified 1 flagged ingredient in this product — components that at least one official source has classified as requiring caution, targeted avoidance, or further evaluation. Flagged ingredients are the items most likely to surface in FDA inspection findings, state-level ingredient bans, or outbreak-related recall notices, so the per-ingredient breakdown below is the most useful lens for anyone screening this product for a specific dietary concern.
On the NOVA processing scale, udon is classified as Group 4 (Ultra-processed). NOVA measures industrial processing intensity rather than ingredient-level safety, so it complements the SAFFA and CSPI ratings: a product can be clean on additive flags but heavily processed, or lightly processed but carry individually flagged ingredients. Combining both lenses gives a fuller picture than either alone. The Nutri-Score grade of C reflects nutritional balance — calories, saturated fat, sugar, sodium versus fiber, protein, and produce content — which again is a distinct dimension from additive safety and worth weighing alongside the scores above.
