Essential metals are elements that our bodies need in small amounts to perform various physiological functions. Metals such as copper, zinc, calcium, iron, and manganese are important for our health and well-being. They are involved in numerous biochemical processes, including enzyme function, hormone regulation, and maintaining the structural integrity of cells and tissues. A deficiency in these metals can result in symptoms like fatigue, frequent illness, and overall weakness, while an excess can also lead to health issues. Therefore, it is important to maintain a balanced diet that includes these essential metals to support our overall health and well-being.

What You'll Learn
Metals are micronutrients
Zinc, for example, is a necessary micronutrient that the human body uses to fight infections and childhood diarrhea. Deficiencies in zinc are responsible for 4% of child morbidity and mortality. Copper and zinc also help support a healthy immune system. However, too much zinc can create a copper deficiency. Similarly, an excess of calcium can interfere with the body's ability to absorb magnesium, which is critical for building bones and teeth, as well as enabling muscle contraction and nerve function.
Metals are naturally occurring in foods and are absorbed by plants from the soil and water. They are then consumed by animals as they eat the plants. For instance, grasses take in iron from the soil, which is then relied upon by animals for hemoglobin production. Humans can get their required intake of metals by eating a healthy diet that includes plenty of fruits, vegetables, beans, whole grains, lean protein, and dairy or calcium-fortified soy products. However, some metals like calcium and potassium may be more difficult to obtain in sufficient amounts through diet alone, and a doctor may recommend taking a supplement.
It is important to note that while metals are essential micronutrients, too much of any one metal can compromise the body's ability to function. Therefore, it is crucial to strike a balance and consult with a healthcare professional before taking any supplements.

They support the immune system
Metals are essential micronutrients that support our overall health and well-being. They are involved in numerous physiological functions and play a vital role in maintaining a healthy immune system.
Zinc, for example, is crucial for regulating certain inflammatory proteins in the body. Low levels of magnesium, another essential metal, are also associated with inflammation. Copper is another metal that helps regulate nerve functions.
A deficiency in metals can result in symptoms such as fatigue, frequent illnesses, nausea, and overall weakness. These symptoms indicate the importance of metals in our body's immune function. For instance, a deficiency in zinc can lead to a copper deficiency, disrupting the balance of these metals in the body, which is crucial for optimal health.
In addition to zinc, copper, and magnesium, other essential metals that support the immune system include calcium, chromium, iron, manganese, molybdenum, potassium, sodium, and selenium. These metals are considered trace minerals, as they are needed in small amounts, yet they have a significant impact on our health.
To ensure adequate intake of these essential metals, it is important to maintain a balanced and diverse diet. However, in some cases, a doctor may recommend supplements to meet individual needs, especially for older adults who may have difficulty absorbing certain metals through diet alone.

Deficiency can cause illness
Nutritional metals are essential for our overall well-being and keeping our immune system strong and functioning. Metal ions such as iron, zinc, copper, selenium, manganese, molybdenum, nickel, and vanadium are essential for the proper functioning of living cells.
A deficiency in these essential metal ions is often linked with an increased risk for various diseases, including infectious diseases, especially among at-risk populations. For example, worldwide, zinc deficiency is responsible for approximately 16% of lower respiratory tract infections, 18% of malaria, and 10% of diarrhoeal disease. Long-term deficiency in copper can cause anemia and nerve damage. Similarly, iron deficiency can cause fatigue, overall weakness, and an increased risk of catching infections.
Deficiencies in some metals can also increase the risk of developing other deficiencies. For example, iron deficiency is the most common metal deficiency, affecting nearly 2 billion people worldwide, and it may be due to underlying zinc and other trace metal deficiencies.
In addition to the above, an accumulation of heavy metals within the body can cause heavy metal poisoning, which can be life-threatening. Heavy metals such as lead, mercury, arsenic, and cadmium can accumulate in the body through ingestion of contaminated food or water, occupational exposure, or exposure to certain products like paint or pesticides. Heavy metal poisoning can cause a variety of symptoms, including abdominal pain, nausea, vomiting, neurological problems, and in severe cases, abnormal heartbeat, brain damage, and kidney damage.
Therefore, it is important to maintain adequate levels of essential metals through a balanced diet or, if necessary, through supplementation. However, caution must be exercised as too much of any one metal can also compromise the body's ability to function.

They're involved in enzyme function
Essential metals are elements that our bodies need in small amounts to perform various physiological functions. They are involved in numerous biochemical processes, including enzyme function, hormone regulation, and maintaining the structural integrity of cells and tissues.
Enzymes are proteins that speed up chemical reactions in living organisms. They are essential for various biological processes, such as digestion and metabolism. Some enzymes contain metals, which are crucial for their function. These metal-containing enzymes are called metalloenzymes.
Transition metals, such as iron (Fe), copper (Cu), manganese (Mn), and zinc (Zn), are commonly involved in enzyme function. For example, the enzyme superoxide dismutase (SOD) contains either copper and zinc (Cu,Zn-SOD) or manganese (Mn-SOD). This enzyme catalyses the conversion of superoxide radicals into hydrogen peroxide and oxygen, which is an important reaction in the body's defence against oxidative stress.
Additionally, the enzyme catalase, which helps to protect cells from the toxic effects of hydrogen peroxide, contains iron as a crucial component. A deficiency or excess of these essential metals can disrupt enzyme function and lead to various disease states, including neurological disorders, mental health problems, cardiovascular diseases, cancer, and diabetes.
Therefore, it is important to maintain a balanced intake of these essential metals through a diverse and balanced diet to ensure optimal enzyme function and overall health.

They're found in a balanced diet
Metals are essential micronutrients that our bodies need to function properly. They are involved in numerous physiological functions, including enzyme function, hormone regulation, and maintaining the structural integrity of cells and tissues. A balanced diet that includes a variety of foods can provide the necessary amounts of these essential metals.
Some of the essential metals found in a balanced diet include iron, zinc, copper, and manganese. These metals are present in various food sources and play vital roles in our overall health and well-being. For example, iron is essential for healthy blood, while zinc supports a strong immune system.
Fruits, vegetables, beans, whole grains, lean protein, and dairy products are excellent sources of essential metals. For instance, spinach is a rich source of manganese, providing 0.84 mg per half cup of cooked spinach. Similarly, brown rice and almonds also contain good amounts of manganese.
In addition to these natural food sources, some processed foods are fortified with essential metals. Breakfast cereals, for example, may be enriched with minerals like iron and zinc. However, it is important to note that while these fortified foods can help bridge the gap, a diverse and natural diet remains the best source of essential metals.
While essential metals are crucial for health, it is important to maintain a balance. Excessive intake of certain metals, even through supplements, can lead to deficiencies in other metals and compromise the body's ability to function optimally. Consulting with a healthcare professional can help ensure that any metal supplements are taken safely and appropriately.
