Document Summary
7 major minerals 8 trace minerals. Minerals do not contain nitrogen and carbon-hydrogen oxygen. Trace minerals < 100 mg/day (not any less important, just less abundant) Calcium + phosphorus combine to form the skeleton. Iron = the most abundant trace mineral: intracellular fluid: fluid within the cells, usually high in potassium and phosphate. 2/3 of the bodies water: extracellular fluid: intercellular spaces, intertestinal fluid: fluid between the cells, usually high in sodium and chloride. Large component of extracellular fluid: inside blood vessels: intravascular fluid: extracellular fluid located within the cardiovascular system of lymphatic system. Water: hard water: high concentration of calcium and magnesium, reduces hypertension, soft water: treated with sodium or potassium, exacerbates hypertension. The greater the mineral content, the harder the water (can smell + taste bad) Minerals have a narrow range of safe intake. Dictated by gender, age, source, combination of foods eaten (binding factors from plants prevents absorption), amount of other minerals consumed.
