The Daily Vitality Score is version 1.0 of one formula, applied here exactly as it was to chips and crackers. Everything is measured per 100 grams so that no bag gains from a small serving.
The full rules, including the judgment calls, live on our methodology page.
The nutrient section is worth 75 points. Sodium carries the most, 20 points, with full marks at 80 mg or less per 100 grams and zero at 1,600 mg. Calories are worth 15 (full at 80 kcal, zero at 800). Saturated fat and added sugars are worth 10 each. Those end points are the first and last thresholds of the 2023 Nutri-Score tables published by Santé publique France, with salt converted to sodium.
Fiber and protein are worth 10 points each, and they are scored per 100 calories so a dry, dense chip can't win on weight alone. Full marks come at 2.8 grams of fiber and 5 grams of protein per 100 calories, which is twice the rate built into the Daily Values in the federal nutrition labeling rule.
Sodium gets the heaviest weight for a reason. More than 70% of the sodium Americans eat comes from packaged and prepared foods, and the average intake is about 3,400 mg a day against a Daily Value of 2,300 mg, according to the Food and Drug Administration.
The ingredient section is worth 25 points. The first ingredient earns 10 if it is a whole food as grown (corn, whole corn, black beans), 5 if it is a whole food that has been dried and ground (corn masa flour, cassava flour), and zero if it is a refined flour, meal or starch. Another 10 points start full and lose 2.5 for each ultra-processing marker, a list we take from Monteiro and colleagues' 2019 paper in Public Health Nutrition: maltodextrin, dextrose, flavors, colors and similar. The last 5 points reward a short list.
Here is the worksheet for one bag, Late July Sea Salt, so the arithmetic is visible. Its label lists 130 calories, 0.5 g saturated fat, 70 mg sodium, 2 g fiber and 2 g protein in 28 grams.
Sodium, for example, works out as 20 × (1,600 − 250) ÷ (1,600 − 80) = 17.8.
Methods box. All 18 labels were read on October 2, 2026. Twelve came from the brand's own product page and six from a major retailer's listing (Late July, Juanita's, Calidad, Beanitos, Good & Gather and the fiber line for Xochitl). Mission's saturated fat line comes from its USDA record because the brand page shows only highlights. One planned product, Food Should Taste Good Multigrain, was replaced by Siete Maíz Sea Salt: its current ingredient list no longer matches the panels we could retrieve. Yeast extract is not on the published marker list, so it is not counted.
We cross-checked each label against the branded foods database at USDA FoodData Central, April 2026 release. Most records for this aisle date from 2021 to 2023, and six of the 18 disagree with the bag on the shelf today. In each case the current label won.
As a check, we also calculated the 2023 Nutri-Score for every chip. Nine come out at grade C and nine at D. The two rankings agree closely: a rank correlation of 0.94 for our nutrient section alone and 0.80 for the full score. The gap between those two numbers is the ingredient list, which Nutri-Score does not look at.
