Where the numbers come from
Nutrient estimates use selected foods from the UK CoFID 2021 dataset. The food’s stated preparation and edible weight are used. Cooked and raw weights are different.
Values are averages, not a laboratory analysis of your meal. Brands, recipes, cooking and portions vary. A trace is rounded to zero. “At least” means some ingredients have missing data for that nutrient; missing data are never assumed to be zero.
Typical serving descriptions are illustrative; the gram weight drives the calculation. Allergen hints are not exhaustive: check your actual ingredients and packaging.

How to use the feedback
This is general food education. It cannot identify a deficiency, diagnose a condition or set individual nutrition requirements. Nutrient amounts in food do not equal amounts absorbed.
A balanced pattern builds across a day or week. See the NHS Eatwell Guide and NHS vitamins and minerals guide for more context.
