COMPILATION COMPREHENSIVE STUDY GUIDE
SOLVED QUESTION SET
◉ T/F Different than the PDCAAS, the DIAAS uses ill vs total
digestibility, a single reference pattern, and is truncated.. Answer: False,
Different than the PDCAAS, the DIAAS uses ill vs total digestibility,
MULTIPLE reference pattern, and is NOT truncated.
◉ T/F Beano contains an enzyme that cleaves the beta bonds in fiber
thereby increasing the fermentation by the microbiota in the colon
decreasing gas production that can lead to flatulence.. Answer: False,
Beano contains an enzyme that cleaves the ALPHA 1-6 BONDS in
OLIGOSACCHARIDES thereby DECREASING the fermentation by
the microbiota in the colon decreasing gas production that can lead to
flatulence.
◉ T/F People with PKU need to avoid foods containing acefulfame-K
because they have a mutation in tyrosine hydroxylase.. Answer: False,
People with PKU need to avoid foods containing ASPARTAME because
they have a mutation in PHENYLALANINE HYDROXYLASE
◉ T/F Since fructose in sucrose is bonded to glucose, it will result in
less free fructose available for uptake than the free fructose found in
high fructose corn syrup.. Answer: False, Since fructose in sucrose is
bonded to glucose, it will result in ROUGHLY THE SAME AMOUNT
,OF fructose available for uptake COMPARED TO the free fructose
found in high fructose corn syrup.
◉ T/F Fermenable, viscous fiber is he best option to increase in
someone wanting to increase their stool bulk to decrease their fecal
transit time. Answer: False, NONFermenable, NONviscous fiber is he
best option to increase in someone wanting to increase their stool bulk to
decrease their fecal transit time
◉ T/F Eicosaniods produced from fatty acids elongated from the omega-
6 essential fatty acid alpha-linolenic acid are more inflammatory than
those produced from fatty acids elongated from the essential omega-3
fatty acid Linoleic acid. Answer: False, Eicosaniods produced from fatty
acids elongated from the omega-3 essential fatty acid alpha-linolenic
acid are LESS inflammatory than those produced from fatty acids
elongated from the essential omega-6 fatty acid Linoleic acid
◉ T/F Saccharine is similar in structure to sucrose, the only difference
being chlorines that replace alcohols groups. Answer: False,
SUCRALOSE is similar in structure to sucrose, the only difference
being chlorines that replace alcohols groups
◉ T/F Sugar alcohols (polyols) are a good option for chewing gum
because they are not readily fermented by bacteria in the mouth
decreasing acid production and thus cavity formation.. Answer: True
, ◉ T/F complementary proteins are two incomplete proteins that have
different lacking amino acids, thus combining them together hey
compensate for the lacking amino acid in the other food.. Answer: False,
complementary proteins are two incomplete proteins that have different
LIMITING amino acids, thus combining them together hey compensate
for the LIMITING amino acid in the other food.
◉ T/F Bile, which is produced by the pancreas and concentrated in the
liver, helps neutralize acidic chyme as it enters the duodenum. Answer:
False, Bile, which is produced by the LIVER and concentrated in the
GALLBLADDER, HELPS EMULSIFY LIPIDS
◉ Name the only macronutrient that is digested to any great extent in the
mouth and the enzyme responsible for this action. Answer:
Carbohydrates, Salivary amylase
◉ Name the components of pancreatic juice. What is the function of
these compnents?. Answer: Bicarbonate and digestive enzymes.
Bicarbonate helps to neutralize the acidic chyme that enters the
duodenum. Most of the digestive enzymes active in the small intestine
are provided by pancreatic juice. Thus, without it digestion of
macronutrients would not occur.
◉ What alternative sweetener is a concern for individuals with PKU?
Why is it a concern for those with PKU?. Answer: Aspartame. It is a
concern because it is broken down into phenylalanine, which is an
amino acid hat individuals with PKU need to limi because they can't
