NUTRITION FINAL TEST Q&A
A small amount of carbohydrate digestion takes place here. - Answer-A. Mouth
No digestion or absorption takes place here. - Answer-B. Esophagus
Proponents of the raw food diet say that because cooking destroys the digestive
enzymes that exist naturally in food, eating lots of cooked food decreases our own
digestive capability, thereby leading to weight gain. This is: - Answer-B. False - We
produce more than enough of our own digestive enzymes and are not dependent on
outside sources.
David is consuming significantly more vitamin C and protein than he needs. Which of
the following statements concerning his intake is CORRECT? - Answer-B. If his
vitamin C intake is high enough, his GI tract will decrease its absorption of the
nutrient, but the absorption of protein won't be affected by its quantity.
A web site on colon cleansing says that "impacted fecal matter lines the wall of the
colon, thus preventing food [from being] digested properly [because] food slides past
this hardened fecal matter." If there really were a lot of impacted undigested food in
the large intestine: - Answer-A. It would have very little impact on digestion and
therefore little impact on body weight.
Which of the following statements concerning sphincters is/are CORRECT? -
Answer-A. They aid in maximizing the digestive and absorptive processes in the
body.
B. They are a type of circular muscle.
*D. A and B*

As part of Callie's medical work-up in the hospital she was asked to swallow a water-

find it? - Answer-A. Capillaries, liver, kidneys
Lewis is terribly constipated. His aunt has an explanation. "It's all that processed and

probably go away if he takes this product.
Which of the following is/are CORRECT regarding cooking? - Answer-A. Cooking is
a type of digestive activity, softening the tough fibrous tissue in plants as well as the
connective tissue in animals.
B. The advent of cooking is believed to have been an important event in human
evolution because it dramatically increased dietary variety, improving nutrient intake.
*D. A and B*
The DRI for total carbohydrate represents: - Answer-B. An amount designed to
encourage consumption of nutrient dense plant foods in addition to the glucose
necessary for basic life processes.
