Answers
food sources of zinc - ANS-Good:
Legumes, Beans, Meats, Peas, Poultry, Nuts, Seafoods (crab meat), Oysters, Steaks,
Bran cereals fortified with Zinc
Bad: Yogurt, Milk,
food sources of iron - ANS-Good: Meat, Fish , Poultry (highest bioavailability)
Spinach, Oysters, Legumes, Oysters
Dried beans.
Dried fruits.
Eggs (especially egg yolks)
Iron-fortified cereals.
Liver.
Lean red meat (especially beef)
Oysters.
Poultry, dark red meat.
bad: oils and fats, sugar and candy
food sources of magnesium - ANS-Good: Tofu, Chili with beans, Wheat Germ,
Cashews, Salmon, Choco chips, Bran Cereal, Spinich (raw), Milk, Green leafy
vegetables, such as spinach, legumes, nuts, seeds, and whole grains,
In general, foods containing dietary fiber provide magnesium. Magnesium is also added
to some breakfast cereals and other fortified foods
Bad: Oranges, Iceberg Lettuce, Poultry, Fish
food sources for calcium - ANS-milk, yogurt, cheese, sardines, salmon, fortified orange
juice, fortified cereal
2. Impaired zinc absorption is related to disease of which organ? What ligand,
, synthesized and released from this organ, helps zinc to be absorbed? Where else is
this
ligand found? - ANS-The pancraes synthesizes a Zn binding ligand (ZBL) called
Picolinic Acid. This assists in the absorption of Zn into the body.
Zinc is recycled
Picolinic acid is also found in breast milk and is a sufficient source for the child for
about 6 months. After this time, the child will need to begin eating meats
3. List 4 functions of zinc in the body - ANS-Cofactor in Proteolytic Enzyme production
(breaks proteins into amino acids)
Acid/base balance (carbonic anhydrase)
Breaks down pyruvate into lactate (glycolosis) Helps for lactose intolerance
Immune functions
wound healing
4. List 2 common sequelae of zinc deficiency in adults. - ANS-Hypogonadism (impaired
testosterone production)
Dwarfism
Impaired wound healing
Acrodermatitis enteropathica- dry scaly skin (deficiency ZBL)
hypogeusia/hyposmia (taste, smell)
Zinc deficiency symptoms include growth and development problems, hair loss,
diarrhea, impotence, eye and skin conditions, and loss of appetite. Other symptoms
may include weight loss, delayed wound healing, taste changes, and mental slowness.
5. Name a common class of drugs used to treat hypertension that can deplete zinc. -
ANS-ACE inhibitors- Lower blood pressure
6. List 4 diseases/conditions in which adequate dietary magnesium may contribute to
therapy. - ANS-Diabetes- Usually causes more Mg to be excreted, but Mg supplements
will slow progression of Type 2 Diabetes
If insulin receptors are unresponsive then glucose....?
Hypertension- Reduces Diastolic BP (works best with decreased Na and increased K
intake)
