Mineral deficiencies occur when the body does not get enough essential minerals, which are vital for various bodily functions. Common minerals include calcium, iron, magnesium, and zinc. A lack of these minerals can lead to health issues such as weakened bones, anemia, and impaired immune function. Symptoms of mineral deficiencies vary depending on the specific mineral lacking. For instance, iron deficiency can cause fatigue and weakness, while calcium deficiency may lead to brittle bones. A balanced diet rich in fruits, vegetables, whole grains, and lean proteins can help prevent these deficiencies and promote overall health.
