Essential Trace Minerals: Zinc, Copper, Manganese, and Selenium

In conditions of low zinc intake, more zinc is transported into the enterocyte than transported out, leading to reduced metallothionein production and potential zinc deficiency symptoms.
Zinc plays a crucial role in various bodily functions, including protecting cells from free radical damage, DNA and RNA synthesis, and immune system function.
Zinc deficiency can lead to symptoms such as poor growth, skin rashes, hair loss, and reduced immune function.
Zinc toxicity can cause gastrointestinal irritation, vomiting, and headaches, and chronic toxicity can result in copper deficiency.
Copper exists in +1 and +2 oxidation states and is essential for functions such as energy production, connective tissue formation, and iron metabolism.
Copper deficiency can lead to symptoms such as anemia, bone abnormalities, and hypertriglyceridemia.
Wilson's disease is a rare genetic disorder that results in copper overload and can cause characteristic Kayser-Fleischer rings in the eyes.
Manganese is essential for various bodily functions, including amino acid, carbohydrate, and cholesterol metabolism, as well as cartilage formation and antioxidant protection.
Selenium deficiency can lead to Keshan disease, affecting the heart muscle, and symptoms such as muscular discomfort and weakness.
Selenium is an essential component of selenoproteins, including glutathione peroxidases, thioredoxin reductases, and iodothyronine deiodinases.
Selenium toxicity can cause symptoms such as nausea, diarrhea, hair and nail changes, and fatigue, and in severe cases, it can lead to death.
The selenium content of plant foods depends on the selenium content of the soil in which they are grown, and soil selenium levels can vary from deficient to very high.
