What essential mineral, concentrated in the *Beta vulgaris* group, is critical for the body's oxygen transport function?

Answer

Iron

Root vegetables belonging to the *Beta vulgaris* family, including the mangelwurzel grown for hardiness and bulk, are known to be accumulators of various vital micronutrients from the soil. Among these, notable levels of Iron are indicated within this broader beet family. Iron is a fundamentally important component required for the production of hemoglobin, which is the protein responsible for efficiently transporting oxygen throughout the entire physiological system. This, combined with other minerals like potassium and magnesium, contributes significantly to its nutritional profile.
