How to read this ranking
This page compares Copper, Cu (Copper, Cu), in mg per 100 g of food.
Chemical forms and measurement methods remain separate. “Not reported” means a value is unavailable, not that the food contains zero. A food’s rank does not determine your individual needs or diagnose a deficiency.
This NIH fact sheet concerns this nutrient. Its recommended amounts describe daily intake for the stated population, not a 100 g food portion. Keep food and supplement exposure separate as the source specifies.
