The nutrition label analyzer scores a food's nutritional profile across 7 FDA-based dimensions — fat quality, sodium, sugar, fiber, protein, micronutrients, and calorie density. Enter values from any nutrition facts label to get an instant health score with per-dimension feedback.

How to Use the Nutrition Label Analyzer
The nutrition label analyzer translates the numbers on a nutrition facts label into a clear health score using FDA daily value guidelines. Whether you're comparing two cereals at the grocery store or tracking your food choices, this tool makes nutritional assessment objective and fast.
Step 1: Enter Values from the Label
Find the "Nutrition Facts" panel on any packaged food and enter each value per serving. The values are always per serving, not per container — this is intentional. A bag of chips that seems fine per serving but contains 3 servings is a common trap the FDA labels are designed to address. You can also toggle between metric (grams/milligrams) and imperial units.
Step 2: Review Your Health Score
The analyzer scores 7 dimensions: Fat Profile (trans fat should be 0, saturated fat under 10% DV), Sodium Level (5% DV = low, 20% DV = high), Sugar Content (added sugars under 10% DV is optimal), Fiber Content (over 20% DV per serving is excellent), Protein Quality (10% DV = good source, 20% = excellent), Micronutrient Score (Vitamin D, Calcium, Iron, Potassium — get more, not less), and Calorie Density (calories per gram of serving weight).
Understanding % Daily Value
The FDA's Daily Value reference amounts are based on a 2,000-calorie diet. The thresholds: 5% DV or less = low (good for sodium, saturated fat, added sugars; concerning for fiber, protein, vitamins), 20% DV or more = high (concerning for sodium and saturated fat; excellent for fiber, vitamins, minerals). Most people's actual calorie needs differ from 2,000 — but % DV remains a useful comparison tool regardless.
Comparing Two Foods
The most useful application is side-by-side comparison. Score Brand A, note the result, then score Brand B. For cereals, the key dimensions are usually sugar content and fiber. For snacks, look at sodium and calorie density. For protein bars, focus on protein quality and added sugars. The health score gives you a single comparable number to make the trade-off explicit.
FAQ
Is the nutrition label analyzer free?
Yes, completely free with no signup required. Enter the values from any nutrition facts label and get an instant health score with specific dietary insights.
Is my data safe?
Yes. All calculations run entirely in your browser. Your data is never sent to any server and stays completely private on your device.
What are FDA daily values?
Daily Values (DV) are reference amounts for nutrients based on a 2,000-calorie diet, established by the FDA for nutrition labeling. The % DV on a nutrition label tells you how much of each nutrient one serving provides relative to the daily recommendation. 5% DV or less is considered low; 20% DV or more is considered high.
How is the health score calculated?
The health score is a weighted average of 7 dimensions: fat profile (saturated and trans fat), sodium level, sugar content, fiber content, protein quality, micronutrient density (Vitamin D, Calcium, Iron, Potassium), and calorie density. Higher scores indicate a more nutritionally balanced food.
Does the score account for serving size?
Yes. All values are entered per serving, as labeled on the product. The tool scores each nutrient's % Daily Value per serving, so a smaller serving size that looks low in sodium may still be problematic if you typically eat two or three servings.
Should I trust this score for medical decisions?
The nutrition label analyzer provides general nutritional information based on FDA guidelines. It is not a substitute for personalized dietary advice. Consult a registered dietitian or healthcare provider for medical nutrition decisions.
