|
Osteoporous
|
associated with calcium defincy in elderly def also tetany, rickets and osteomalacia
|
|
|
Sodium
|
reduction of the mineral can prevent water retention and lower blood pressure
|
|
|
Plasma Potassium levels
|
critcal for heart action
|
|
|
Chloride
|
mineral that maintains gastric acidity and water balance , resides in ECF
|
|
|
Upper tolerable limit for sodium
|
2300mg/da
|
|
|
Calcium
|
Mineral in greatest amount in body, Immobility causes withdraw of it
|
|
|
Aldosterone
|
controls excretion of sodium, used by kidneys conserves sodium
|
|
|
Electrolytes
|
Ions that influence water balance
|
|
|
Binding substances of calcium
|
oxalates and phytates
|
|
|
Albumin
|
plasma protein with most colloidal pressure /maintains water balance ( prevents h2o retention)
|
|
|
Clinical roles of calcium
|
Nerve impulses and muscle contractions
|
|
|
Sulfur
|
form keratin in hair and nails, organic form - methionine heparin, insulin biotin, found with protein
|
|
|
Potassium
|
47000 mg/day Found in intra cellular fluid and balances extra cellular sodium
|
|
|
Phosphorus
|
1250 mg/day 9-18 years General metabolism and bone formation
|
|
|
Potassium functions
|
offsets pressor effect of sodium - Lowers blood pressure = higher potassium
|
|
|
ADH
|
vasopressin ( anti diuretic )causes kidney to retain water
|
|
|
Thirst mechanism
|
prevent dehydration but doesnt work in elderly
|
|
|
Magnesium
|
energy production, bone health , 400 mg- men 310 mg- for women, 80% of mineral is lost when the germ and bran is removed
|
|
|
Adequate intake of sodium
|
1500mg/da for age 19-50
|
|
|
DASH
|
diet rich in calcium and potassium( veg and fruit) lowers blood pressure
|
|
|
Adequate intake of Calcium
|
1000mg/da for age 19-50
female- 650 male- 900, up during growth |
|
|
Muscle mass
|
has direct relationship witth influence of water content in body
|
|
|
Major minerals
|
Calcium(Ca), Phosphorus (P) , Magnesium ( Mg) Soudium ( NA), Potassium( K), Sulfur ( S), Chloride (Cl)
|
|
|
Ca balance
|
1-Intake absorp - excret- balane
2-bone blood balance 3- calcium phosphorus blood balance |
|
|
1-Intake absorp - excret- balance of Ca
|
Positive bone mineral gain= more in and less out
Negative loss= less in and more out |
|
|
2-bone blood balance of Ca
|
Dynamic - Daily exchange of 500-700 mg
|
|
|
3- calcium phosphorus blood balance of Ca
|
constancy of soulubility factors- muscle contract and hyperphosphatemia( more phosphorus = less Ca
|
|
|
Colon Cancer and Ca
|
Os Cal supplement promotion
|
|
|
Phosphorus absorption
|
Regulated by Vit D calcitriol and PTH, Kidneys are main excrete routwe, Mosly plasma p absorped in kidney
|
|
|
Phosphorus stored
|
80-90 % in skeleton norme range- 3.0-4.5 mg
|
|
|
Phosphorus functions
|
Absorp of glycerol and glucose, trans of fatty acids, and energy metabolism
|
|
|
Sodium functions
|
fluid balance - maintains ECF, muslce and nerve activity
|
|
|
Potassium ( K ) functions
|
water balance - manitains ICF bal works with Na ( ECF) , muscle activity, blood pressure - aids in sodium elimination via aldosterone
|
