What is CoFID?
- Reference data for UK foods
- Nutrients expressed on a consistent basis
- Useful alongside packaged-food sources
CoFID is the UK Composition of Foods Integrated Dataset published by the UK government. It provides reference nutrient composition for foods commonly eaten in the UK and is different from a live catalogue of every branded supermarket product.

Provenance and version matter
CoFID is UK reference-food data, not a live supermarket catalogue
The Composition of Foods Integrated Dataset is published by the UK government and provides nutrient composition for foods commonly eaten in the UK. Its entries support consistent reference values. A specific branded product may require current label data because ingredients and formulations can differ or change.
Read the food description precisely
Preparation state, edible portion and food type matter. A raw item may not match a cooked entry, and drained or trimmed values can use a different basis. Confirm that the description is the closest relevant food before applying a portion.
Keep dataset version and measurement basis visible
Values are commonly expressed per 100g, which supports comparison and portion calculation. Record the source and release context so later corrections remain possible. Use current packaged-food information alongside CoFID when the actual item is branded.
