Copper is a micromineral, or a mineral our body needs in small amounts. Its main role is to help form collagen and hemoglobin, while it also acts as an antioxidant that helps eliminate free radicals. Deficiency results in anemia, but over consumption cal lead to diarrhea, cramps and mild vomiting. The Recommended Dietary Allowance (RDA) for copper is 900 mcg/day and the Daily Value (DV) is 2mg. Here is a list of the foods high in copper.
1. Beef Liver
A 3-ounce slice of beef liver has 14 mg copper, which is more than 100% of the DV. It supplies the 900 micrograms recommended amount of copper for adult men and women on a daily basis. It also has vitamin A and other essential minerals such as zinc, iron, selenium and phosphorus.
