|
|
Sodium (Na+)
|
-Function:
*Major ion & primary ruglator of ECF V *Helps maintain acid-base balance *Essential to muscle contraction and nerve conduction -Source *Salt, soy, MSG -Effect: *high levels contribute to hypertension *May effect calcium and bone loss |
|
|
Chloride (CL-)
|
-Function:
*Critical to F&E balance *Major ion in ECF *Can move freely across cell membrane *Helps maintain acidity of gastric flds -Source: *Salt |
|
|
Potassium (K+)
|
-Function:
*Major ion intracellular *Maintains F&E balance & cell integrity *Critical to regular heart rhythm *Carbohydrate & protein metabolism -Source: *fresh fruits (strawberries), vegetables -Deficiency: *Related to excessive losses (diarrhea, diuretics, steroid use) |
|
|
Calcium (CA++)
|
-Function:
*Essential for healthy bones & teeth *Helps regulate muscle contraction, nerve impulse, blood clotting, hormone secretion, digesive enzymes, neurotransmitters *Vitamin D & hormones important for bone deposit -Sources: *Milk, grains, eggs, legumes, & nuts -Deficiency: *Chronic leads to bone loss (major problem for US women -Most amount: Figs |
|
|
Iron (FE+)
|
-Function:
*Hemoglobin synthesis *General metabolism -Source: *Meat, eggs, vegetables, & cereal *Absorbed better w/vitamin C *Need increase intake with pregnancy, lactation, and poor diet -Deficiency: *Most prevalent deficiency in the world |
