Document Summary
Maintain structure and regulate chemical reactions and body processes. 20 needed by the body in small amounts. Major mineral: need > 100mg/day, sodium, potassium, chloride, calcium, phosphorous, magnesium, and sulfur. Trace mineral: need < 100 mg/day, iron, copper, zinc, selenium, iodine, chromium, fluoride, manganese, molybdenum, and others. You can maximize your diet"s mineral content by eating a variety of foods: look at table with food groups and minerals found in them. Affected by: amount in soil, processing, added (for example, during fortification, removed (for example, by cooking or removing skins, bran, or germ, absorption and bioavailability, sometimes inhibited by substances in plants, other plants, amount in body. Phy- tates can be broken down by yeast so the bioavailability of minerals is higher in yeast than regular breads. Regulate body processes: for example, if you had no sodium, you wouldn"t reabsorb water when filtrated through kidneys. Affect growth and development through their role in the expression of cer- tain genes.
