How many minerals are known to be essential
25
-
Functions of Minerals
Building tissue and activating, regulating, transmitting and controlling metabolic processes
-
Mineral Metabolism
- Digestion - absorbed and used in ionic form
- Absorption
- Transport - travel thorughout the body bouned to plasma protein
- Tissue Uptake - Minerals go to target tissue and excess excreted in pee
-
Occurences in the Body
They occur as free ions in body fluids or they occur covalently bound with another mineral
-
Calcium (Ca)
Function
Function: Bone and teeth formation, blood clotting, muscle contraction and relaxtion, nerve transmission
-
Calcium
Deficiency
Tetany, Rickets, Osteoporosis
-
Calcium Toxicity
Increase risk of kidy stones, constipation, interferes with absorption of other nutrients
-
Phosphorus (P) Functions
Bone and Tooth formation, energy metabolism, DNA and RNA, acid-base balance
-
Phosphorus Deficiency
unlikely, but can cause bone loss, loss of appetite, weakness
-
Phosphorus Toxicity
Bone resorption and loss of calcium
-
Sodium (Na) Function
- Major extra cellular fluid control
- water balance
- acid-base balance
- Muscle action
- ttransmission of nerve impulse and resulting contraction
-
Sodium Deficiency
- Fluid Shifts
- acid base imbalace
- cramping
-
Sodium toxicity
- Hypertension in salt sensitive people
- && edema
-
Potassium (K) Functions
- Major intracellular fluid control
- acid-base balance
- regulation of nerve impulse and muscle contraction
- blood pressure regulation
-
Potassium Deficiency
- Irregular heatbeat
- difficulty breathing
- muscle weakness
-
-
Chloride (Cl) Functions
- Acid-base balance (chloride shift)
- Hydrochloric acid (digestion)
-
Chloride deficiency
- hypochloremic alkalosis in porlonged vomiting
- diarrhea
-
Chloride Toxicity
Not set and unlikely
-
Magnesium )Mg) functions
- Coenzyme in metabolism
- muscle and nerve action
- aids thyroid hormone secretion
-
Magnesium Deficiency
- Tremor
- spasm
- low serum level after GI losses or renal losses from alcoholism
- Convulsions
-
Magnesium toxicity
Nausea, vomiting, diarrhea
-
Sulfur functions
- Essential constituent of cell protein, hair, skin, nails, vitamin, and collagen structure
- high energy sulfur bounds in energy metabolism
-
Sulfur deficiency and toxicity
not likely
-
What are major minerals
calcium, phosphorus, sodium, potassium, chloride, magnesium, sulfur
-
what are the trace minerals
iron, iodine zinc selenium fluoride, copper, manganese, chromium, molybdenum
-
Iron Functions
Hemoglobin and myoglobin formation, cellular oxidation of glucose antibody production
-
Iron deficiency
- anemia
- pale skin
- impaired immune function
-
Iron Toxicity
- Nausea vomiting diarrhea
- liver kidney heart and CNS damage
-
Iodine Functions
Synthesis of T4 which regulates cell oxidation and BMR
-
Iodine deficiency
Goiter, cretinism, hypothyroidism, hyperthyroidism
-
-
Zinc Functions
- essential enzyme constituent
- protein metabolism
- storage of insulin
- immune system
- sexual maturation
-
Zinc deficiency
- Impaired wound healing and taste and smell acuity
- retarded sexual and physical development
-
Zinc toxicity
Nausea, vomiting, decreased immune function, impaired copper absorption
-
Selenium Functions
Forms glutathione peroxidase, spares vitamin e as an antioxidant, protects lipids in cell membrane
-
Selenium Deficiency
- Impared immune function
- KESHAN DISEASE
- heart muscle failure
-
Selenium Toxicity
- brittleness of hair and nails
- GI upset
-
Fluoride functions
- constituent of bone and teeth
- prevents cavities aka dental caries
-
Fluoride deficiency
increased dental caries
-
fluoride toxicity
dental fluorosis
-
copper functions
- associated with iron in energy production
- hemoglobin synthesis
- absorption and transport of iron
- nerve and immune function
-
copper deciciency
anemia, bone abnormalities
-
copper toxicity
- WILSONS disease
- resulting in lever and nerve conduction damage
-
Manganese functions
- activates reaction in urea synthesis
- energy metabolism
- lipoprotein clearance
- and sythesis of fatty acids
-
Manganese deficiency
clinical deficiency present only in protein energy malnutrition
-
Manganese toxicity
inhalation toxicity in miners, neuromuscular disturbances
-
Chromium functions
Associated with glucos metabolism
-
Chromium deficiency and toxicity
deficiency- impared glucose metabolism
toxicity - not likely
-
Molybdenum (Mo) Functions
Constitutent of many enzymes
-
Molybdenum deficiency and toxicity
Unlikely
-
Keshan Disease
a heart muscle disease that primarily affects yound children and women of childbearing age and can lead to heart failure from cardiomyopathy
-
Osteoporosis is cause by
- inadequate calcium intake
- poor intestinal calcium absorption
- lack of physical activity
Osteoporosis - loss of bone density
