aids in absorption of iron & work with iron to synthesize hemoglobin
what are the functions of copper?
involved in formation of bones & teeth by increasing retention of calcium (can sometime substitute calcium)
what are the functions of fluoride?
major portion of RBCs & oxygen metabolism, produce 2.5 million RBCs per second, vitamin C increases absorption of dietary iron
what are the functions of iron?
assist in mineralization of bones & teeth, assist in the immune system via protein synthesis, inhibits blood clotting & muscle contraction
what are the functions of magnesium?
control water balance, muscle contraction & nerve transmission, tissue synthesis, antioxidants, energy metabolism but yield no energy
what are the functions of minerals?
assist with calcium & vitamin D in the formation of bones & teeth, regulates acid-base balance, necessary for muscle contraction
what are the functions of phosphorus?
regulates electrolyte balance (+ charge ion = intracellular) - part of sodium pump, pumps waste products outside of cell, regulate acid-base balance, essential role in nerve transmission & muscle contraction
what are the functions of potassium?
maintains electrolyte balance (+ion that works with -ion in chloride), regulates acid-base balance, aids in nerve & muscle contraction
what are the functions of sodium
antioxidant & used to preserve foods
what are the functions of sulfur?
involved in taste & smell sensitivity, would healing & immunity, develops pigment needed for night vision, aids in insulin storage in pancreas
what are the functions of zinc?
stronger bones & teeth, resistance to caries, remineralizes caries areas
what are the health benefits of fluoride?
hypocalcification (incomplete tooth calcification)
what are the oral manifestations of calcium deficiencies?
angular cheilosis, & pale lips & oral mucosa
what are the oral manifestations of iron?
impaired taste
what are the oral manifestations of zinc?
vomiting & diarrhea
what are the toxicities of copper?
can occur in with abnormal kidney failure, and overconsumption of potassium salts or supplements (including energy fitness shakes)
what are the toxicities of potassium?
GI disturbances, hair loss, fingernail discoloration, halitosis
what are the toxicities of selenium?
known to increase risk of hypertension (common)
what are the toxicities of sodium?
lack of muscle coordination, interferes with copper absorption, alters cholesterol metabolism & may weaken blood vessels
what are the toxicities of zinc?
if water deficiency causes dehydration there can be a high concentration of Cl in blood
what are toxicities of chloride?
dental fluorosis (mottled enamel - discoloration & pitting of tooth enamel during tooth development)
what are toxicities of fluoride?
excessive absorption with overconsumption of vitamin C & iron poisoning
what are toxicities of iron?
reduced calcium absorption = bone loss (Ca & P compete for absorption)
what are toxicities of phosphorus?
food & water
what can restore chloride balance?
high calcium intake
what competes with magnesium absorption?
80% of bones & teeth
what does phosphorus make up
phytochemicals
what in certain foods can bind with minerals & make them unavailable to the body?
table salt - 40% Na & 60% Cl
what is a food source of sodium & chloride?
Ca
what is calcium's element symbol?
K
what is element symbol for potassium?
magnesium
what is the 3rd most prevalent mineral in teeth & bone?
500 mg/day (1/4 teaspoon)
what is the adequate intake for sodium?
dental caries
what is the deficiency of flouride?
Cl
what is the element symbol for chloride?
Cu
what is the element symbol for copper?
