About NutritionRanked
NutritionRanked is a free nutrition research tool that scores and ranks 80,091 grocery products across 9 health goals — including heart health, weight loss, blood sugar management, and muscle building — using verified nutrition label data from Open Food Facts and USDA FoodData Central.
Our Mission
Grocery shopping shouldn't require a nutrition degree. We built NutritionRanked to give every shopper a clear, data-driven answer to "What should I eat for my health goal?" — no guesswork, no marketing claims, just numbers from real nutrition labels.
Data Sources
Every score on NutritionRanked is derived from two primary data sources covering lab-tested and community-verified nutrition information:
Open Food Facts
The world's largest open-source food database with over 3 million products. Community-verified nutrition labels, ingredients lists, NOVA processing classifications, and additive data. Licensed under ODbL.
world.openfoodfacts.org →USDA FoodData Central
The U.S. Department of Agriculture's lab-tested nutrition database. Provides gold-standard nutrient values for branded and generic foods sold in the United States.
fdc.nal.usda.gov →Scoring Methodology
Each product receives a score from 1 to 10 for each of our 9 health goals. Scores are calculated using a multi-factor algorithm that weighs different nutritional attributes based on scientific evidence for that specific goal:
| Goal | Primary Factors |
|---|---|
| 🫀 Heart Health | Saturated fat, fiber, sodium, oil types, cholesterol-lowering ingredients |
| 💪 Muscle Building | Protein per calorie ratio, absolute protein content |
| 🔥 Weight Loss | Calorie density, fiber (satiety), protein, sugar content |
| 🩸 Blood Sugar | Fiber-to-carb ratio, sugar content, whole grains, refined starches |
| 🦴 Bone Health | Calcium sources, protein, sodium (calcium excretion), phosphoric acid |
| 🧠 Brain Health | Omega-3 sources, sugar, fiber (gut-brain axis), artificial additives |
| 🏃 Energy | Complex carbs, fiber, sugar (crash risk), protein, calorie adequacy |
| 🌱 Clean Label | NOVA processing group, additive count, ingredient list length |
| 👶 Kids / Growing | Sugar, sodium, additives, protein, calcium sources |
Scores start at 5 (neutral) and are adjusted up or down based on how each factor compares to evidence-based thresholds. Final scores are clamped between 1 and 10. A score of 8+ is labeled "Great," 6–7 is "Good," 4–5 is "Okay," and 1–3 is "Watch."
