Trace minerals
Trace minerals
Trace minerals, also known as trace elements, are a group of chemical elements that are required by living organisms in minute amounts for proper physiological and biochemical functioning.
Pronunciation
- Trace minerals: /treɪs ˈmɪnərəlz/
Etymology
The term "trace minerals" is derived from the fact that these elements are present in the body in very small or "trace" amounts.
Definition
Trace minerals are essential nutrients that the body needs to work properly, but in much smaller amounts than vitamins and other minerals. They include elements like iron, zinc, copper, manganese, selenium, and iodine.
Importance
Trace minerals play crucial roles in a variety of physiological processes, including enzyme function, hormone production, bone development, immune system support, and oxygen transport.
Sources
Trace minerals are typically obtained through the diet. Foods rich in trace minerals include seafood, nuts, seeds, meat, poultry, and whole grains.
Deficiency and Toxicity
Both deficiency and excess of trace minerals can lead to health problems. For example, iron deficiency can cause anemia, while excess iron can lead to hemochromatosis. Similarly, iodine deficiency can result in goiter, while excess iodine can cause thyroid problems.
