Microminerals at optimum concentrations: Protection against diseases

Abstract

Microminerals are as necessary as macrominerals but in lower doses. Drinking water may be a substantial source. Low selenium and Mo is connected to heart diseases and cancer. Lithium decreases the incidence of violent crimes and suicide. Boron and chromium (Cr–III) from drinking water may be beneficial. Goiter is uncommon where iodine in drinking water is high. Fluoride is protective against dental caries, but too much causes bone deformations. On the other hand, even though copper and iron are nutrients, concentrations >0.2 mg/L may cause diarrhoea, and elevated manganese may negatively affect the nervous system. Safe health–bringing ranges of nutrient elements are suggested in the chapter.
