Minerals are essential for human health and can be classified into two groups: major minerals and trace minerals. Major minerals, which include calcium, chloride, magnesium, phosphorus, potassium, sodium, and sulfur, are used and stored in large quantities in the body. On the other hand, trace minerals like chromium, copper, fluoride, iodine, iron, manganese, molybdenum, selenium, and zinc are equally vital, but we only need small amounts. Minerals are important for keeping our bones, muscles, heart, and brain healthy, and they also play a role in making enzymes and hormones. A balanced and varied diet that includes a variety of whole foods like vegetables, fruits, whole grains, lean protein, and dairy products can provide us with the necessary minerals. However, some individuals, such as those with chronic illnesses or specific dietary restrictions, may be at risk of mineral deficiency and may need to consider supplements or dietary adjustments.

What You'll Learn
Minerals are essential for bodily functions
Minerals are essential for the body to perform a range of functions and stay healthy. They are known as micronutrients as they are needed in smaller amounts. The body cannot produce minerals, so we must obtain them from our diet.
Minerals are vital for building bones, influencing muscle and nerve function, and regulating the body's water balance. They are also important for making enzymes and hormones. For instance, calcium is required for the formation of bones and teeth, while iron is necessary for the normal function of the nervous system.
There are two main types of minerals: macrominerals and trace minerals. Macrominerals, also known as major minerals, are needed in larger amounts and include calcium, phosphorus, magnesium, sodium, potassium, chloride, and sulfur. Trace minerals, also called microminerals or minor minerals, are needed in smaller amounts but are equally important for bodily functions. They include iron, manganese, copper, iodine, zinc, cobalt, fluoride, and selenium.
A healthy and varied diet that includes all five food groups is usually sufficient to provide the body with the required minerals. Foods such as vegetables, fruits, whole grains, lean meats, and reduced-fat dairy products are good sources of minerals. However, certain individuals, such as those with chronic illnesses, older people, and pregnant women, may be at risk of mineral deficiency and may need to pay closer attention to their mineral intake.

Calcium is important for bone health
Minerals are essential for the human body to stay healthy and perform various functions. They are required for keeping our bones, muscles, heart, and brain working properly. Our body uses minerals to make enzymes and hormones.
Calcium is a mineral that is crucial for building and maintaining strong bones and teeth. It is stored in bones and helps give them strength. Calcium is also important for other physical functions, such as muscle control and blood circulation.
Our bodies do not produce calcium, so it must be obtained through our diet. Dairy products, such as milk, cheese, and yogurt, are excellent sources of calcium. Other calcium-rich foods include vegetables like broccoli, kale, and cabbage, seafood like trout and sardines, nuts and seeds, and fruits like oranges and strawberries.
Calcium supplements are also available and are often recommended for older adults, especially those with osteoporosis, to ensure adequate calcium intake and maintain bone health. However, it is best to obtain calcium from your diet if possible, as excessive calcium from supplements can have adverse health effects, including kidney stones and an increased risk of heart problems.
In addition to calcium, vitamin D is crucial for bone health as it helps the body absorb calcium effectively. Vitamin D can be obtained through exposure to sunlight, and certain foods like fish, milk, and yogurt are also good sources.

Iron deficiency can cause anaemia
Minerals are essential for the human body to function properly and stay healthy. They are required for various bodily functions, including keeping our bones, muscles, heart, and brain working properly, as well as making enzymes and hormones. A balanced diet that includes a variety of foods ensures we get the right amount of minerals our bodies need.
Iron is one such essential mineral, and iron deficiency can lead to anaemia. Iron-deficiency anaemia is a common blood disorder that affects red blood cells. It occurs when there is insufficient iron in the blood, usually due to blood loss. Women are particularly at risk due to blood loss during menstruation. Additionally, pregnant women are susceptible to iron deficiency anaemia as their iron stores need to serve their increased blood volume and provide haemoglobin for the growing fetus.
Other causes of iron deficiency anaemia include intestinal disorders, such as celiac disease, which affects the body's ability to absorb nutrients from food. Frequent blood donors may also be at risk as blood donation can deplete iron stores. Furthermore, certain medications, such as non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen and aspirin, can cause gastrointestinal bleeding and contribute to iron deficiency anaemia.
Iron-deficiency anaemia can cause fatigue, shortness of breath, dizziness, lightheadedness, chest pain, and a rapid or irregular heartbeat. It can be treated with iron supplements or infusions, as well as by consuming iron-rich foods such as meat, eggs, leafy green vegetables, and iron-fortified products. However, self-diagnosis and treatment are not recommended. It is important to consult a healthcare provider who can determine the appropriate treatment plan and address any underlying causes of the condition.

Zinc supports immune function
Minerals are essential for human health and are classified into two equally important groups: major minerals and trace minerals. Major minerals are used and stored in large quantities in the body and include calcium, chloride, magnesium, phosphorus, potassium, sodium, and sulfur. On the other hand, we require smaller amounts of trace minerals, such as chromium, copper, molybdenum, fluoride, iodine, iron, manganese, selenium, and zinc.
Zinc, a trace mineral, is essential for immune function. Zinc deficiency can have detrimental effects on the immune system, increasing susceptibility to a variety of pathogens. For instance, a lack of zinc can dysregulate intracellular killing, cytokine production, and phagocytosis in macrophages, which play a pivotal role in many immunologic functions. Similarly, zinc deficiency slows the recovery of T-cell numbers, which are crucial infection-fighting cells.
The importance of zinc in immune function was highlighted in a study by Fred Hutchinson Cancer Research Center scientists, who discovered that zinc is required for the development of specialized immune cells. Furthermore, zinc prompts a critical immune organ, the thymus, to regenerate after damage. This discovery has therapeutic potential for individuals receiving blood stem cell transplants for the treatment of serious blood diseases.
In summary, zinc is crucial for maintaining optimal immune function. Adequate zinc intake helps ensure the proper development and functioning of various immune cells and organs, contributing to the body's ability to fight off infections and maintain overall health.
