Mineral Deficiency - GCSE Biology Definition

Mineral deficiency occurs when the body does not get enough of the essential minerals it needs to function properly, which can lead to health problems. Important minerals include iron (for making red blood cells), calcium (for strong bones and teeth), and potassium (for nerve and muscle function). If someone doesn’t eat enough foods containing these minerals, or if their body can’t absorb them properly, they might experience symptoms such as tiredness, weak bones, or muscle cramps. In GCSE Biology, understanding mineral deficiency helps explain how a balanced diet is essential for maintaining health and preventing disease.
