Nutrition Final - Trace Minerals Flashcards
Trace minerals (function)
facilitate metabolism, energy production, cell repair, support bodily structures including bones, muscles, organs, hormones…
Work synergistically with vitamins and other essential nutrients in small amounts.

Iron (function)
-Found in HEmoGlobin and MyoGlobin
- oxygen transport and storage
- oxidation-reduction rxns
- DNA synthesis
Heme vs Nonheme Iron (& foods)
Heme = 10% of avg iron intake and well absorbed.
-40% of Fe in meat, fish and poultry = heme
Nonheme - accounts for 90% but is less well absorbed.
-iron in foods derived from plants = nonheme
Foods:
Heme - meat, poultry, fish
Nonheme - meat, dried fruit, nuts, seeds, soy

- broccoli
Iron (excess/def)
Excess :
Iron overload
Hemochromatosis
Def: Iron storage depletion Early fx Fe def. Iron def. anemia -fatigue, weakness, tachycardia, tachypnea

Zing (excess/Def)
Excess :
Vomiting, nausea, diarrhea, HA, fatigue
Def. :
Children:
stunted growth, immature sexual development.
Adults:
