Minerals are essential nutrients that our bodies need in small amounts to function properly. They help our bodies grow and stay healthy, from building strong bones to sending nerve impulses. We cannot produce minerals in our bodies, so we must obtain them from our diet. A healthy balanced diet containing a variety of foods should provide all the minerals our bodies need to work properly. For example, calcium helps build strong bones and teeth, while iron is used to make hemoglobin in red blood cells, which carry oxygen around the body. Other important minerals include potassium, sodium, magnesium, and zinc, each playing vital roles in maintaining overall health.

What You'll Learn
Calcium helps build strong bones and teeth
Calcium is a mineral that is essential for building and maintaining strong bones and teeth. It is not produced by the body and must be obtained from dietary sources. Dairy products are a good source of calcium, but individuals who are lactose intolerant or vegan may need to seek alternative sources, such as calcium-fortified juices or supplements.
Calcium works in conjunction with other vitamins and minerals to ensure bone health. For instance, vitamin D is necessary for the body to effectively absorb calcium. Without sufficient vitamin D, the body struggles to utilise calcium, potentially leading to conditions like osteoporosis, characterised by fragile bones. Vitamin K is also important, as it helps with bone formation and may assist in directing calcium to the bones.
Phosphorus is another key mineral that aids in calcium absorption. It is readily available in most foods, especially high-protein options like meat, milk, and nuts. Magnesium, found in bone crystals, improves bone strength, and can be obtained from dietary sources such as spinach, bananas, and chickpeas.
While calcium is renowned for its role in bone and teeth health, it also contributes to other essential physical functions. These include muscle control and blood circulation. Thus, adequate calcium intake is vital for overall health and wellbeing.

Iron is used to make haemoglobin in red blood cells
Minerals are inorganic substances that are essential nutrients found in foods. They are important because our bodies cannot manufacture them and must obtain them from our diets.
Minerals help to release energy from food. For example, sodium, potassium, and chloride are minerals that work to maintain water balance and provide the correct pressure between cells and their surrounding fluids.
Minerals also play a role in building and strengthening bones and teeth. Calcium, for instance, is used by the body to build bones and teeth.
Minerals are also used to make haemoglobin in red blood cells. Iron is an essential component of haemoglobin, a protein in red blood cells that helps carry oxygen throughout the body. About 70% of the iron in the human body can be found in haemoglobin. Iron is not made in the body and must be absorbed from food. When iron intake is low, stores can become depleted, decreasing haemoglobin levels.
Iron is also vital for a fully functioning immune system. It is also needed for energy metabolism and as a component of enzymes involved in the synthesis of collagen and some neurotransmitters.

Magnesium activates enzymes, muscles and nervous functions
Minerals are important nutrients found in foods. They are inorganic substances and are needed for many bodily functions. Major minerals like calcium, phosphorus, magnesium, sulphur, potassium, sodium, and chloride are needed in amounts of 100mg or more each day.
Magnesium is a macromineral with a multitude of roles in the human body. It is a cofactor in more than 300 enzymatic reactions. It is essential for the regulation of muscle contraction, including that of the heart, and plays a vital role in maintaining muscle health. Magnesium ions carry a 2+ positive charge, allowing them to bind with negatively charged molecules. This unique ability to interact with diverse chemical structures makes magnesium the most versatile intracellular cation, participating in nearly every major metabolic and biochemical process within the cell.
Magnesium is also important for nerve transmission and neuromuscular conduction, as well as protecting against excitotoxicity, or excessive excitation that can lead to neuronal cell death. It has been implicated in multiple neurological disorders, including migraine, chronic pain, epilepsy, Alzheimer's, Parkinson's, and stroke, as well as anxiety and depression.
Magnesium's role in nerve transmission and neuromuscular coordination is closely linked to its impact on muscle health and function. Skeletal muscle health is fundamental to human functionality, mobility, and overall well-being. Magnesium is a crucial component in the regulation of biological processes within cells, and skeletal muscle houses approximately 20% of the body's total magnesium. As the body ages, there is a noticeable decline in muscular function, and magnesium levels can be negatively impacted, affecting overall health and quality of life.
In summary, magnesium is a vital mineral that activates enzymes, muscles, and nervous functions, contributing to overall health and well-being.

Phosphorus aids energy metabolism, calcium absorption and cell growth
Minerals are essential nutrients that our bodies require to perform a range of functions. They are inorganic substances that we get from our diet since our bodies cannot manufacture them. Phosphorus, in particular, is a key mineral that aids energy metabolism, calcium absorption, and cell growth.
Phosphorus is the second most abundant mineral in the body, after calcium. It plays a crucial role in energy metabolism, where it helps the body store and use energy. Phosphorus is required for the conversion of protein, which is essential for the growth, maintenance, and repair of cells and tissues. It is also necessary for the production of genetic building blocks, such as DNA and RNA.
In terms of calcium absorption, phosphorus works closely with calcium to build strong bones and teeth. About 85% of the body's phosphorus is found in bones and teeth, with smaller amounts present in cells and tissues throughout the body. The balance between calcium and phosphorus is vital for proper bone density and the prevention of osteoporosis. Additionally, phosphorus helps filter out waste in the kidneys and can reduce muscle pain after a workout.
Phosphorus is readily available in most foods, especially high-protein foods such as meat, milk, whole grains, nuts, and seeds. Adults need 550mg of phosphorus per day, and it is unlikely that anyone will need phosphorus supplements. However, excessive phosphorus in the body can be more concerning than a deficiency and is usually caused by kidney disease or a diet high in phosphorus and low in calcium. Therefore, it is important to maintain a balanced diet that includes a variety of food groups to ensure adequate mineral intake.

Potassium helps maintain water balance and supports muscle and nerve function
Minerals are important nutrients found in foods that help in various body processes. Major minerals like calcium, phosphorus, magnesium, and potassium are needed in the diet in amounts of 100 milligrams or more each day.
Potassium is a vital mineral that helps maintain water balance and supports muscle and nerve function. Firstly, potassium is an electrolyte that helps regulate fluid balance in the body. It is the primary electrolyte within body cells, with roughly 98% of potassium in the body found in cells, and it determines the amount of water inside them. The body's fluid balance is important for optimal health, as inadequate fluid balance can lead to dehydration, affecting the heart and kidneys.
Secondly, potassium is essential for muscle contractions and maintaining muscle function. About 80% of the potassium in the body is found in muscle cells, and changes in blood potassium levels can directly impact muscle contractions. Low potassium levels can cause muscle weakness, cramps, and constipation.
Lastly, potassium supports nerve function by facilitating the transmission of electrical signals between cells. It helps nerve cells fire properly when stimulated, allowing the brain to communicate with other cells in the body. Potassium also plays a role in regulating nerve impulses, which are necessary for several bodily functions.
Overall, potassium is a critical mineral for maintaining water balance, muscle function, and nerve health, and a potassium-rich diet is associated with numerous health benefits.
