welche mineralien braucht der körper — what does this mean exactly?

The question 'which minerals does the body need' refers to the essential inorganic nutrients that humans must obtain from food because they cannot synthesize them. These include macrominerals such as calcium, magnesium, potassium, sodium, phosphorus, and chloride, as well as trace minerals like iron, zinc, copper, manganese, selenium, iodine, molybdenum, and chromium. Each mineral has specific roles: calcium and phosphorus for bone health, magnesium for muscle and nerve function, potassium and sodium for fluid balance, iron for oxygen transport, zinc for immunity and wound healing, selenium for thyroid and antioxidant defense. Recommended intakes vary by age, sex, and life stage (e.g., pregnancy). Blood tests can detect deficiencies, but indiscriminate supplementation without medical guidance is risky. DNA tests like those from MyBody-X can indicate genetic predispositions (e.g., FUT2 for B12 absorption) but do not replace clinical assessment. The evidence for the essentiality of these minerals is human-strong, based on decades of nutritional science.
