About
NutrientNorms is a structured reference for nutrient composition of foods. Every page answers one question: how much of a given nutrient is in a given food, per 100g, relative to everything else in the dataset.
The data comes from USDA FoodData Central. NutrientNorms reorganizes that data into pages that are easier to scan, compare, and rank across foods and nutrients. No interpretation, no recommendations, no health claims. The numbers speak for themselves.
Why this exists
USDA data is rich, but it is not always easy to browse by nutrient question. If you want to know which foods are highest in magnesium, how kale compares to spinach, or where a food sits relative to everything else, you often have to do that assembly yourself.
NutrientNorms is built to make those comparisons immediate: structured pages, consistent per-100g values, and rankings that let you move from a single food to the wider landscape around it.
What you can do here
- Browse foods by category or alphabetically
- Compare nutrient density per 100g across foods and preparation states
- See which foods rank highest for a given nutrient
- Check where a food sits within the full dataset or within its category
How the site is structured
NutrientNorms has three main browse paths. You can start from the question you already have, then move sideways into related pages as needed.
Nutrients
Start with one nutrient, see which foods are highest in it, then open that nutrient in a specific food.
Foods
Start with a category or food group, open a specific variant, then see that food's full nutrient profile.
Rankings
Start with a leaderboard, inspect a top food, then jump into the full food page for broader context.
These paths connect to each other throughout the site. A nutrient page links into rankings, a ranking page links into foods, and food pages link back into nutrient-specific comparisons.
What this is not
- A diet or meal planning tool
- A source of medical or nutritional advice
- A substitute for professional guidance
