A trace mineral is an element that is present in the human body in small amounts (as much as it represents less than 0.01% of total body weight). Still, his role is very important. When we eat a varied diet, we receive a sufficient amount from abroad to guarantee its presence in the body.
In fact, the deficiency of trace elements is rare in developed countries (except for iron deficiency). However, you should not lower your guard in two circumstances: unbalanced diets and malabsorption.
- Zinc. The main sources of Zinc are: red meat, pork, lamb, oysters, shellfish, cereals, legumes, beans and nuts. Zinc is a nutrient for the intestine, the skin, the skin appendages and the eyes. It is not surprising that its deficit, which appears in a disease called acrodermatitis enteropathica, is associated with digestive symptoms (diarrhea, abdominal pain); skin symptoms (reddish hair, lesions on the face, hands, feet, and diaper area); and eye symptoms (photophobia, conjunctivitis). This disease can have a hereditary basis.
- Copper. The main sources of copper are: cereals, legumes, cherries, nuts, soybeans, oysters and liver. Copper is necessary for the skin and its appendages to develop properly, as well as the nervous system. Copper deficiency is associated with: fragile hair, rosy cheeks, hypotonia, hypothermia, mental retardation, peripheral neuropathy, and blood disorders. It may also have a genetic basis (Menkes syndrome).
- Magnesium. Magnesium is present in nuts, cereals and legumes. Its main functions are: fix calcium to the bones and promote bowel movements. In addition, it participates in the induction of sleep and relaxation. Its deficit can lead to tremors, seizures and severe constipation.
In summary: the human body is a complex laboratory, with elements present in very small quantities, but whose function is remarkable. Hence the importance of nurturing ourselves in the most varied way possible.
