Aside from the mineral nutrients, what aspect of milk has been
implcated as a reason that milk inpake may reduce hypertension?
Select one:
a. the water in milk is poorly absorbed, which lowers the total blood
volume
b. proteins digestions results in small peptides that block angiotensin
converting enzyme
c. lactose is slowly digested and absorbed relative to other
carbohydrates, and the reduced blood glucose causes the heart to
pump less forcefully
d. milk is rich in sphingomyelin that lubricates the blood vessels -
ANSWERS-b. proteins digestions results in small peptides that block
angiotensin converting enzyme
Milk is thought to increase body weight because
Select one:
a. the lactose is an excellent prebiotic food that increases the bacterial
mass in the colon.
,b. it is a high calorie food if it displaces water in the diet.
c. the calcium and phosphate add to bone mass.
d. the vitamin D prevents the wasting associated with rickets. -
ANSWERS-b. it is a high calorie food if it displaces water in the diet.
Dairy product intake is thought to be responsible for weight loss or
reduced weight gain because
Select one:
a. the amino acid pattern of the whey protein causes rapid muscle
breakdown.
b. the high calcium intake reduces calcitriol, which reduces
intracellular ionized calcium, thereby promoting lipolysis and
decreasing lipogenesis.
c. the high level of riboflavin promotes satiety and reduces taste
sensitivity. - ANSWERS-b. the high calcium intake reduces calcitriol,
which reduces intracellular ionized calcium, thereby promoting
lipolysis and decreasing lipogenesis.
The hormone rBST improves the energetic efficiency of milk
production because a greater proportion of the feed energy is directed
to milk synthesis and a lower proportion is directed to maintenance of
the animal. This is an example of biotechnology promoting
sustainable agriculture because...
Select one:
a. rBST changes milk composition to improve human health.
,b. the cows will produce less of the the greenhouse gases CO2 and
CH4 per unit of milk produced.
c. it greatly reduces the profit margin of farmers because of the cost of
the drug.
d. it would be desirable for cows to eat much less feed and produce
only slightly less milk. - ANSWERS-b. the cows will produce less of
the the greenhouse gases CO2 and CH4 per unit of milk produced.
Even though pasteurization requires additional energy before the milk
get to the consumer, we could consider this a sustainable agricultural
practice because...
Select one:
a. the vitamin and mineral content of the milk is increased by
pasteurization.
b. the heat energy in the milk is totally recovered before packaging.
c. less milk is discarded due to spoilage and fewer pathogens in milk
means less disease and higher productivity.
d. the electricity for heating milk can be produced from renewable
resources. - ANSWERS-c. less milk is discarded due to spoilage and
fewer pathogens in milk means less disease and higher productivity.
Comparing a breast pump to a bovine milking machine shows that
Select one:
a. both extract milk by reducing atmospheric pressure at the end of the
nipple or teat.
, b. both have a high probability of contaminated milk refluxing into
the gland and causing mastitis.
c. both have a cyclic pressure change that massages the tissue form
the outside.
d. both maintain a constant level of vacuum until all the milk is
collected. - ANSWERS-a. both extract milk by reducing atmospheric
pressure at the end of the nipple or teat.
Possible reasons that camel milk consumption might reduce the
incidence of diabetes include ALL of the following EXCEPT
Select one:
a. zinc may stabilize the insulin present in camel milk.
b. camel milk has an epigenetic effect on individuals with a family
history of diabetes.
c. a bioavailable form of insulin in the camel milk.
d. high antioxidant activity in the camel milk. - ANSWERS-b. camel
milk has an epigenetic effect on individuals with a family history of
diabetes.
What bioactive compounds help camel milk lower blood pressure? -
ANSWERS-Angiotension I-converting enzyme(ACE) inhibitory
activity(like bovine milk)
What bioactive compounds help camel milk have a
Hypocholesterolaemic effect? - ANSWERS--Orotic acid
-Bacterial & milk peptides
