Document Summary
Margie is a 75 year old recent retiree who lives alone and is in good health. Today, she is expecting a visit from her family so she is rushing to pick up some groceries. She is rushing around and falls to the ground after feeling a pain. Unlike vitamins, minerals are inorganic elements needed for structure and regulation of body processes. Also unlike vitamins, minerals are not sensitive to heat or cooking processes, light, oxygen, or acid so they are harder to destroy. They are classified into major minerals, amount needed > 100 mg/day (make up >0. 01% body weight) and trace elements required in amounts < 100 mg/day (exist as <0. 01% of body weight). The trace elements are required in smaller amounts. Grain products: iron, zinc, selenium, copper, magnesium, chromium, sulfur, manganese, sodium, potassium, and phosphorus. Vegetables and fruit: iron, calcium, potassium, magnesium, and molybdenum. Milk and alternatives: calcium, zinc, phosphorus, potassium, iodine, and molybdenum.
