Copper is a malleable, ductile and slightly corrosive mineral. It is widely used in industry, mainly in electrical wiring and as a component of many machine parts. It also appears, alone or combined with other mineral in the manufacture of bells, coins, cooking utensils, insecticides, paints, fertilizers, food additives, dyes, etc. .) In fact, it is the third most common mineral in the world after iron and aluminum.
The importance of copper throughout the history of humanity has been crucial. Remember that there is a period of it in which humans used it as material in the manufacture of weapons and utensils (Copper Age). During another period, it was used together with tin to make bronze, an alloy that gave name to this period of humanity (Bronze Age)
When it was substituted by iron and steel in the manufacture of articles of common use, it was intended primarily to electrical wiring and electrical equipment as well as water pipelines, coins and components of many machines.
Copper is a mineral that is necessary for the proper functioning of the body. Its deficiency can occur in any of the following anomalies:
Excess copper in the body is harmful and is manifested in the form of a disease called Wilson disease.
Where can copper be found?
- Animal sources of copper: Shellfish is the main animal source of copper, with oysters which have the highest amount. Organ meats (liver, kidneys, heart, intestines, etc.) are also important source of copper.
- Copper plant sources: vegetables rich in copper are whole grains, legumes, nuts and avocados. (More information on foods rich in copper in the listing above)
- Accidental sources of copper: The oxidation of copper pipes produces the incorporation of copper into the water. By drinking this water, we ad copper to our body. Another accidental source of copper comes from copper vessels used for preparing food, such as pots and copper kettles. Many of them are made of copper alloys such as nickel silver(= alpacca), which is formed by the mixture of copper, nickel and zinc. Years ago most of the houses cutlery was made from nickel silver. Today is still being used for making luxury cutlery, crockery or containers because of its brightness and because its appearance resembles silver. In fact, it is known as German silver or new silver .
- Supplements: Another way of obtaining this mineral is by means of supplements. The following possibilities exist:
- Copper Aspartate
- Copper Citrate
- Copper Picolinate
Copper supplements should be taken only by prescription, after he has made a proper diagnosis of the reasons for the origin of the lack of this mineral.
A balanced diet usually provides adequate daily intake of this mineral. However, the intake of copper supplements may be necessary in certain cases where there is poor absorption of this mineral, for example, gluten intolerance (celiac disease), Crohn's disease or albinism.
It could also be appropriate to take copper supplements when taken pills for heartburn in a usual manner, as this type of medicine makes the intestinal absorption of copper. Very restrictive diet foods rich in copper could also be responsible for the deficiency.
Copper supplements in the form of capsules and tablets should be taken with the main meal. This will decrease the chances of developing stomach problems.
Most copper supplements are sold in combination with zinc. When taking zinc supplements for more than 30 days, we recommend a daily intake of copper supplement of about 2 mg as zinc interferes with copper absorption.
