How the food nutrition score works

The score answers one narrow question: how much does 100g of a food contribute to a fixed set of adult daily nutrient targets? It is a comparison tool, not a health rating.

The calculation

We compare the food's per-100g amount against 20 daily nutrient targets used in Nutrigate. Each nutrient can contribute up to one point, so a very high amount of one nutrient cannot dominate the result.

The score is the average of those capped contributions, shown from 0 to 100. Protein, fibre, minerals and vitamins are included. Calories, total fat, saturated fat and sodium are shown alongside the score because they need their own context.

What it does not tell you

A score cannot tell you whether a food is right for your medical needs, allergies, diet or portion. It also cannot replace a whole dietary pattern. A high score does not make a food a treatment, and a low score does not make a food a bad choice.

Nutrigate's daily score is different. It uses your own targets and everything you have eaten that day. Food pages use one fixed reference so any two foods can be compared on the same basis.

Data and portions

Food values come from Nutrigate's USDA FoodData Central-derived generic-food table. FoodData can vary with variety, recipe, cooking method and brand. The page also calculates a typical serving from the same per-100g data, so you can see a more familiar portion.

We show the source link on every page. When you are comparing a packaged product, use its own nutrition label because it is more specific than a generic food entry.
