In order to be classified as a vitamin, a compound must meet a
number of criteria to be an essential nutrient. Check all that apply: -
Answer -the body can't synthesize enough of the compound to
maintain health and absence of the compound from the diet for a
defined period produces deficiency symptoms that, if caught in time,
are quickly cured when the substance is resupplied
Matching vitamins with their roles - Answer –

D: a hormone
E: antioxidant that prevents breakdown of Vitamin A
K: activates blood clotting factors
Why are older people at increased risk for vitamin B-12 deficiency
compared to younger people? - Answer -As you age, your stomach
produces less acid, which limits cleavage of vitamin B-12 from food.
In addition, decreased production of intrinsic factor by the stomach
limits vitamin B-12 absorption

Fat-soluble vitamins - Answer -vitamins that travel with dietary fats
through the blood stream, vitamins that are stored mostly in the liver
and fatty tissues, and vitamins A, D, E, and K
Water-soluble vitamins - Answer -vitamins that are readily excreted
from the body, vitamins that are easily lost during food processing
and preparation, and vitamins that include the B vitamins and vitamin
C
Vitamin roles - Answer -a. D: increases calcium and phosphorous
deposition in bones
b. K: assists with blood clotting
c. B-6: important for hemoglobin synthesis
d. A: important for vision
e. E: donates electrons to neutralize free radicals
The B vitamin content of a whole grain is dramatically decreased
during the refining process. To counteract these losses, in the United
States, food manufacturers are required to enrich breads and cereals
from milled, refined grains with which B vitamins? (Check all that
apply): - Answer -niacin, Riboflavin, thiamin, and folic acid
