If you are trying to eat more Copper, ranked lists are useful because the best options are often not the most obvious ones. The foods below are ordered by Copper content in mg per 100 g, drawn from the foods in our database.
Dried herbs, spices, garlic and chilli are excluded from this ranking. Per 100 g they top almost every nutrient table — ground turmeric alone would lead on iron, potassium and manganese — but they are eaten a teaspoon at a time, so listing them as a source would be misleading.
Remember: ranking by one nutrient is only one way to choose foods. Pairing matters too. Use the Copper compound page to understand absorption, forms and interactions.

How to actually eat more Copper
A handful of additions usually move the needle more than a full diet reset. Copper is best consumed from whole foods rather than supplements whenever possible. Try adding one new source each week, track how you feel, and build from there rather than forcing every meal to hit a target.

Common questions
How much Copper do I need a day? Needs differ by age, sex, life stage and health status. The figures here are not prescriptions; use them to compare foods, then apply your own context.
Are supplements better than food sources? Not automatically. Food provides co-factors such as fibre, fat and other micronutrients that help the body use Copper effectively. Supplements are useful for filling confirmed gaps.
