Some foods rich in copper, which are used to ensure the maintenance of blood health, include cooked veal or beef liver, mussels, raw or cooked oysters, whole grains, cashews, peanuts, almonds, nuts or chocolate, for example.
Copper deficiency in the body is rare because the amount of copper found in food is sufficient to meet the copper needs that the body needs. On the other hand, excess copper in the body can cause diarrhea or metallic taste in the mouth, for example.
