What You'll Learn
Minerals help build bones and teeth
Minerals are essential nutrients that our bodies need in small amounts to function properly. They are known as micronutrients and are usually classified as either major or trace minerals.
Minerals help to build bones and teeth in the following ways:
Calcium is a mineral that is vital for building and maintaining strong bones and teeth. It is the most abundant mineral in the body and is stored in bones and teeth to help make and keep them strong. If you do not get enough calcium, your bones will eventually become weak and brittle and can lead to conditions like osteoporosis. Good sources of calcium include dairy products like milk, yoghurt and cheese, as well as some plant-based foods with added calcium such as soy milk, tofu and certain breakfast cereals. Other sources include almonds, bok choy, kale, parsley, broccoli and watercress.
Phosphorus is another mineral that is present in bones, teeth and DNA. It works with calcium to create hydroxyapatite, the main structural component of bones and tooth enamel. Phosphorus is found in a wide range of foods, including seafood, beef, pork, cheese, soybeans, lentils and pumpkin seeds.
Magnesium is a mineral that improves bone strength and is primarily found in bone crystals. Older adults are more likely to be deficient in magnesium. It can be found in foods such as spinach, bananas, nuts, seeds, avocados and chickpeas.
Potassium is a mineral that helps the body control the balance of fluids and keeps the heart healthy and functioning correctly. It is needed for muscles, nerves and cells to function properly. Most people get all the potassium they need from their diet, and it can be found in a variety of foods, including meat, milk, wholegrains, nuts and seeds.
Iron is a mineral that helps the body make red blood cells to carry oxygen around the body. It is also important for cell growth, development and normal body functions.
Zinc is a mineral that is needed for proper immune function, and a deficiency can lead to increased susceptibility to infection. It is also essential for the maintenance of vision, taste and smell.
Sodium is a mineral that is a component of salt and is naturally present in most foods. However, most people consume more salt than is good for their health.
Iodine is a mineral that the body needs to make thyroid hormones, which control metabolism and are important for bone and brain development during pregnancy and infancy.

They are essential for the nervous system
Minerals are essential for the human body to function properly and must be obtained from our diet. They are needed in smaller amounts than vitamins and are typically measured in milligrams (mg) or micrograms (mcg).
Minerals like calcium and iron are necessary for the normal functioning of the nervous system. Calcium is vital for building and maintaining bones and teeth, and it also plays a role in regulating your heartbeat and ensuring your blood clots normally, which is important for healing. Iron, on the other hand, helps your body produce red blood cells, which carry oxygen throughout your body. A deficiency in iron can lead to iron deficiency anaemia.
Magnesium is another extremely important mineral for nerve function. It activates enzymes, muscles, and various nervous functions. A deficiency in magnesium can lead to muscle cramps, headaches, loss of appetite, insomnia, and an increased predisposition to stress.
Zinc is also essential for maintaining vision, taste, and smell. Adequate zinc levels are necessary for proper immune function, and a deficiency can lead to increased susceptibility to infections.
Overall, a balanced and varied diet that includes whole foods should provide your body with the necessary minerals to support the nervous system and overall health.

Minerals are important for the immune system
Minerals are inorganic nutrients that are required by the body in small amounts for various physiological functions. They are essential for the body to perform a range of functions, from building strong bones and teeth to supporting the nervous system.
Minerals are vital for the optimal functioning of the immune system. A deficiency in minerals can temporarily impair immune competence and disrupt the long-term regulation of systemic inflammation. For instance, zinc deficiency results in increased susceptibility to infections. Similarly, manganese is essential for the proper functioning of enzymes involved in immune responses, and its deficiency can lead to impaired immune function and increased susceptibility to infections.
Iron (Fe), a vital dietary mineral, plays a crucial role in the development and functioning of the immune system, as well as processes like erythropoiesis (red blood cell production) and cellular energy metabolism. Iron deficiency can lead to iron deficiency anaemia. Copper (Cu) deficiency is rare, but it can lead to extensive symptoms such as anaemia and bone damage.
A well-balanced diet that includes a variety of nutrient-rich foods is crucial for ensuring an adequate intake of these essential minerals. In rare cases of deficiency, mineral supplementation may be necessary, but excessive consumption of certain mineral supplements can have adverse effects on the immune system.
Overall, minerals are indispensable components of a healthy diet and play a crucial role in supporting the immune system.

They help regulate the body's water balance
Minerals are essential nutrients that our bodies need in small amounts to function properly. They are called micronutrients and are typically measured in milligrams (mg) or micrograms (mcg).
Minerals help regulate the body's water balance. They are also involved in building bones and teeth, influencing muscle and nerve function, and regulating hormones and enzymes. A mineral deficiency can lead to several health issues. For instance, a lack of calcium can result in weak and brittle bones, while insufficient iron can lead to iron deficiency anaemia.
Some key minerals and their functions include:
- Calcium: This is the most abundant mineral in our bodies and is vital for building and maintaining strong bones and teeth. It also helps regulate the heartbeat and ensure normal blood clotting. Good sources of calcium include dairy products, certain plant-based foods, and green leafy vegetables.
- Iron: Iron is necessary for the production of red blood cells, which carry oxygen around the body. Meat, fish, and green leafy vegetables are good sources of iron.
- Potassium: This mineral helps control the body's fluid balance and supports heart health. It can be found in foods such as meat, milk, and wholegrains.
