KHP 240 QUIZ #2 QUESTIONS AND VERIFIED ANSWERS,
100% GUARANTEE
Describe the importance (overall) of carbohydrates as substrate. - primary energy source
during exercise
monosaccharides - Single sugar molecules
disaccharides - Carbohydrates that are made up of two monosaccharides
polysaccharides - Carbohydrates that are made up of more than two monosaccharides
what must first happen to galactose and fructose before it can be oxidized for ATP synthesis? -
Must be converted to glucose in the liver (slow energy source)
soluble fiber - -slows down digestion-feel full for a long time
-fermented by bacteria
-binds to cholesterol in S.I.
Ex. oats, carrots, potatoes.
insoluble fiber - -+ bulk (attracts H2O) since it does this it increases attraction of
carsogenosens and scrap the wall to clean
-decreases fecal transit time
-softer/larger stool; promotes bowel movement
Ex. whole grains, nuts, green beans
which type of dietary fiber is known to decrease cholesterol, blood glucose, and decrease risk of
obesity and diabetes? - soluble fiber
, which type of dietary fiber is associated with reduced risk of colon cancer by reducing the
exposure of toxic substances that develop as a by-product of digestion? - Insoluble fiber
what are the dietary fiber recommendations for men: women 19-50 yrs old - 38g: 25g
what are the dietary fiber recommendations for men: women >50 yrs of age - 30g: 21g
Glycemic Index (GI) - -amount that food causes your blood glucose to rise
-increases in blood glucose and insulin in response to isolated food
-the greater the glucose response= increase in GI
-high >70
-low <55
Glycemic Load (GL) - -takes into account amount of CHO consumed
-may not truly reflect glycemic effect of food (We don't eat foods in isolation)
-GL=(GI x CHO content g/serving) /100
-high > or = 20
-medium 11-19
-low < or = 10
what is gluten - structural protein naturally found in certain cereal grains. often refers to
wheat protein, in medical literature refers to combination of prolamin and glutelin proteins
naturally occurring in all grains
what is celiac disease and what effect does it have on nutrient absorption? - an
autoimmune disorder of the S.I. Caused by rxn to gluten, when eaten the body produces an
inflammatory rxn which truncates (shortens) the villi of the S.I. therefore, impairing nutrient
absorption
