About copper in this data

FNDDS reports copper in milligrams, and the FDA’s Daily Value is 0.9 mg, one of the smallest on the label. Beef liver holds more than ten times that in one slice. Shellfish, seaweed, soy foods, nuts and seeds follow.

For what copper does in the body and how much people need, see Copper: Fact Sheet for Consumers, NIH Office of Dietary Supplements.

How these lists work

The full method

Track copper in Calorie Tape

Calorie Tape logs every nutrient a food reports, copper included, and shows which foods your day’s copper came from. It works offline, needs no account, and keeps your log on your iPhone.
