NCSU NTR 401 final exam questions with
correct answers
"Reference height and weight" | | |
|relative to nutrient intake refers to: - CORRECT ANSWER✔✔-average
| | | | | | | | |
heigh of the US male and female populations and the associated weight
| | | | | | | | | | | |
for the midpoint of the healthy range of BMI
| | | | | | | |
Diverse populations around the world consume sodium at levels greater
| | | | | | | | |
|than the Upper Tolerable Intake Level set in the DRIs. One explanation
| | | | | | | | | | | |
for this "sodium appetite" is that humans choose a sodium intake that
| | | | | | | | | | | |
does not trigger an excessive secretion of the hormone ________ -
| | | | | | | | | | |
CORRECT ANSWER✔✔-renin |
Biological scientists study the regulation of food intake in terms of the
| | | | | | | | | | | |
gut-brain and adipose-brain hormonal axis. In contrast, nutritionists
| | | | | | | |
who take a more holistic view of human ecology frequently refer to
| | | | | | | | | | | |
_______, which can include the concept of _______ to explain the
| | | | | | | | | | |
current prevalence of obesity. - CORRECT ANSWER✔✔-the
| | | | | | |
socioecological model, neuroeconomics | |
,The DRI value that is most likely to be applicable to 100% of the
| | | | | | | | | | | | | |
population, i.e. not be established as a percentage of the normal
| | | | | | | | | | |
distribution is - CORRECT ANSWER✔✔-UL | | | |

the breakdown and absorption of fast in the intestine? - CORRECT
| | | | | | | | | | |
ANSWER✔✔-pepsin
The dietary component that is the precursor of monoacylglyceride and 2

According to the Institute of Medicine's Dietary Reference Intake
| | | | | | | | |
guidelines, a nutritionist using the RDA to plan meals for a population
| | | | | | | | | | | |
must take into account several sources of variation that allow
| | | | | | | | | |
calculation of the percentage of the population that would meet their
| | | | | | | | | | |
requirements. Among the following, the LEAST IMPORTANT source of | | | | | | | | |
uncertainty would be: - CORRECT ANSWER✔✔-organic foods have
| | | | | | | |
different nutrient content than conventionally grown foods, as is usually
| | | | | | | | |
noted on the labels or in the nutrient database
| | | | | | | | |
,The best way to change the dietary intake of a population for a given
| | | | | | | | | | | | | |
nutrient is to: - CORRECT ANSWER✔✔-educated people about food
| | | | | | | | |
choices or modify the nutrient profile of foods most commonly eaten
| | | | | | | | | |
Which factors were LEAST likely to be considered important in
| | | | | | | | | |
determining the age and gender categories for Dietary Reference | | | | | | | | |
Intakes? - CORRECT ANSWER✔✔-different racial and ethnic groups may
| | | | | | | | |
have different nutrient requirements
| | |
"Zymogen" can be defined as: - CORRECT ANSWER✔✔-Protein that can| | | | | | | | | |
become an active enzyme through proteolysis at a location outside the
| | | | | | | | | | |
cells where it is synthesized
| | | |
The absorptive epithelial cells lining the gastrointestinal tract are called"
| | | | | | | | |
- CORRECT ANSWER✔✔-enterocytes
| | |
The hormonal feedback loop between the last segment of the small
| | | | | | | | | | |
intestine and the pyloric sphincter, involving substance GLP-1, is
| | | | | | | | |
referred to as an "ideal brake." The outcome of this process is that an
| | | | | | | | | | | | | |
increase in GLP-1: - CORRECT ANSWER✔✔-decreases flow of chyme to
| | | | | | | | | |
the ileum |
All of the following factors stimulate or increase thirst EXCEPT: -
| | | | | | | | | | |
CORRECT ANSWER✔✔-increased blood volume presumably detected
| | | | | |
by cardiac stretch receptors
| | |
, Given that we regulate the amount of food we consume to maintain
| | | | | | | | | | | |
energy balance, what is the principal way we can be sure we have
| | | | | | | | | | | | |
adequate intake of vitamins and minerals? - CORRECT ANSWER✔✔-
| | | | | | | |
learn to consume a variety of nutrient dense foods
| | | | | | | |

| | | | | | | | | | | | |
that cannot be synthesized in humans is generally referred to as -
| | | | | | | | | | | |
