Minerals

Understanding Minerals

• Minerals are essential nutrients that your body needs in small amounts to work properly. They are substances that come from the earth and are present in various types of food.
• Minerals are divided into two types: macro-minerals and trace minerals. Macro-minerals, such as calcium, potassium and magnesium, are required in larger amounts. Trace minerals, like iron, zinc and iodine, are needed in smaller quantities.
• They cannot be produced by the body and must therefore be sourced from your diet. They are generally found in high quantities in fruits, vegetables, dairy, and lean proteins.

Role of Minerals in the Body

• Calcium is vital for building strong teeth and bones, and necessary for blood clotting and muscle contractions.
• Potassium helps to control the balance of fluids in the body and aids in nerve function and muscle contraction.
• Iron is necessary for the production of red blood cells which carry oxygen around the body.
• Zinc assists with healing wounds, proper functioning of the immune system, and DNA synthesis.
• Iodine contributes to the production of thyroid hormones which are important for growth and metabolism.

Importance of Balanced Intake

• A healthy, balanced diet usually provides all the minerals your body needs to function properly.
• Overconsumption of certain minerals, like sodium, can contribute to high blood pressure, heart disease, stroke and kidney disease.
• Conversely, insufficient mineral intake can lead to various deficiency diseases. For instance, lack of iron can result in anaemia.
• Drink plenty of water to help your body absorb the minerals it requires.

The key is to understand the role of each mineral in maintaining good health and to ensure you are getting a balanced intake of minerals through a varied diet.
