Copper is an essential mineral required by the body for bone & connective tissue production, and for coding specific enzymes that range in function from eliminating free radicals to producing melanin. A deficiency in copper can lead to osteoporosis, joint pain, lowered immunity, and since copper is essential for the absorption of iron, anemia. Conversely, over-consumption of copper will lead to cramps, diarrhea, and vomiting in the short term, and can lead to depression, schizophrenia, hypertension, senility, and insomnia in the long term. The stomach needs to be acidic in order to absorb copper and thus antacids interfere with the absorption of copper, as do milk and egg proteins. The current RDA for copper is 2mg. Below is a list of high copper foods.
Pumpkin seeds contain 3.1 mg of copper per cup or 156% of the RDA.
Six medium oysters contain 2.4 mg per cup or 120% of the RDA.
Sunflower seeds contains 2.3 mg per cup or 115% of the RDA
Sesame seeds contain 1.9 mg per cup or 95% of the RDA.
Walnuts contains 1.9 mg per cup or 93% of the RDA.
soybeans contains .7 mg per cup or 35% of the RDA.
Lentilscontains .5 mg per cup or 25% of the RDA.
Crimini mushrooms contains .4 mg per cup or 20% of the RDA.
Quinoa contains .4 mg per cup or 18% of the RDA.
