welche mineralien braucht der körper — what are common causes?

The question about essential minerals and common causes of deficiency is a standard topic in nutritional medicine. The body requires macrominerals such as calcium, magnesium, potassium, sodium, phosphorus, and trace elements like iron, zinc, iodine, selenium, and copper. Common causes of deficiency include unbalanced diet (e.g., low intake of whole grains, vegetables, dairy), increased needs (growth, pregnancy, athletic training), malabsorption (e.g., celiac disease, Crohn's disease), or medications (e.g., proton pump inhibitors leading to magnesium depletion). However, the provided knowledge contexts contain no information about minerals. They exclusively cover genetic variants (COMT, TAS2R38, FOXO3, NQO1, SLCO1B1, ACTN3) related to neurotransmitter metabolism, taste perception, longevity, detoxification, statin tolerance, and athletic genetics. Therefore, I cannot derive an evidence-based answer from the given material. The response below is based on general medical knowledge, not on the contexts. For individual assessment of mineral deficiencies, blood tests and medical consultation are required.
