Inorganic elements that our bodies need in order to function. Major minerals: we need more than 100mg/day. Calcium, phosphate, and magnesium trace elements we need less than 100mg/day. Calcium, magnesium, phosphorous, and fluoride are needed for the structures of bones. Iodine is used to make thyroid hormones. Iron is needed for oxygen transport in red blood cells. Many minerals are needed as cofactors for enzymes (cofactors = activates an enzyme) 65% minerals hydroxyapatite (calcium and phosphorus crystals) 35% organic substances collagen (a fibrous protein) Minor roles: magnesium, vitamin k, vitamin a, protein, fluoride. A major mineral we need > 1,000 mg/day. The most abundant mineral in the body. It makes up 1-2% of our body weight! Milk alternatives and fortified foods (calcium fortified orange juice and soy milk) Fish eaten with bones (canned salmon, sardines) Dark green vegetables kale, bok choy, chard, broccoli. Only about 25% of calcium food is absorbed.
