Minerals are simply described as inorganic nutrients needed in adequate amounts for bodily functions. Important minerals include trace elements like iodine, zinc, iron, and micronutrients such as potassium, calcium, sodium, and magnesium. However, deficiency diseases can occur if these minerals are lacking in one’s diet for an extended period. That’s more reason why you need to always eat a balanced diet that contains a sufficient amount of these minerals, alongside vitamins and other nutrients.
