Study Notes
Minerals
- Minerals are classified into macrominerals and microminerals (trace elements) based on the body's needs
- Macrominerals are needed in amounts greater than 100 mg/day
- Macrominerals include calcium, phosphorus, magnesium, sodium, potassium and chloride
- Microminerals are needed in amounts less than 100 mg/day
- Microminerals include chromium, cobalt, copper, fluoride, iodine, iron, manganese, molybdenum, selenium, zinc, and silicon
Calcium
- Most calcium in the body is hydroxyapatite (Ca10(PO4)6(OH)2)
- Dietary sources include milk, dairy products, green leafy vegetables, seafood, almonds, blackstrap molasses, broccoli, enriched soy and rice milk products, figs, soybeans, and tofu
- Factors increasing calcium absorption include calcitriol (active form of vitamin D), acidic pH, and lysine and arginine amino acids
- Factors inhibiting calcium absorption are not specified in the text.
