Copper-rich foods

The content of copper in the human body is negligible and it is estimated that it is only 80 micrograms (about 1/40 of that of iron). The content is not much, but the function is much more complicated than iron.

Copper is the active ingredient of more than 30 enzymes in the body; many biochemical reactions in the body of copper show amazing catalysis. Copper also participates in important life activities such as growth hormone, hypophysis, and sex hormones. Although copper is not a raw material for hematopoiesis, hematopoiesis can not do without it. It promotes the absorption of iron in the gastrointestinal tract and sends iron to the bone marrow for hematopoiesis to promote red blood cell maturation. In addition, there is a copper-containing enzyme in the body's elastic tissue and connective tissue that can catalyze the maturation of collagen, maintain the elasticity of blood vessels and the toughness of bones. Copper can also regulate heartbeat, copper deficiency can induce coronary heart disease.

Although copper is important, excessive absorption is also harmful. Adults need 30 micrograms of copper per kilogram of body weight per day. The liver, kidneys, oysters, mussels, shrimps, crabs and sesame seeds, dried beans, walnuts, sunflower seeds, green leafy vegetables, taro and eggplants in natural foods contain copper. The body's normal dietary structure is generally not copper deficient.
