Copper is a metal that is essential in our diet and for different functions in the body. It is found naturally in the soil, water and air, but also as part of food.
In the past, some cultures such as the Greeks, Egyptians and even Aztecs used copper preparations to relieve sore throats and rashes. Today, copper is used for many purposes, such as antifungal remedies, antiseptics and more.
Note that copper should be included in our diet, but in an appropriate ratio: when used in excess, copper can be toxic and cause side effects such as diarrhea, vomiting, bone fractures, schizophrenia and osteoporosis.
Copper in food
Our body requires at least 2 mg of copper per day and the best way to consume copper is through a balanced and varied diet. It is suggested that many plant foods are rich in this metal, although this depends on the richness of the soil in which they were planted. Otherwise, 50 grams of nuts or other seeds can usually meet our daily requirement of copper.
Currently, chocolate and cocoa products are often the main sources of dietary copper today. A chocolate bar of about 100 grams may contain 1 mg copper. If the chocolate is combined with milk, i.e. milk chocolate, the proportion of copper is much lower.
Chicken, rice, tea and even dairy products are considered low in copper, but because their consumption is usually in larger amounts, they can become an important source of this mineral.
According to the WHO (World Health Organization), about 20 % of the population suffers from disorders associated with a diet deficient in copper. The most common are moderate to severe anemia, edema, bone demineralization, anorexia, changes in hair colour, stunted growth, fatigue and skin pigmentation.
That is why we recommend a daily dose of 3 mg per day, to avoid any of the above symptoms which are associated with its deficiency.
