NUTR 331 Midterm Review
nutrition - answer-the study of function and interaction of nutrients,
and the processes by which the body uses them
what makes a nutrient essential - answer-required for growth, required
for regulation of body processes, required for repair of body tissue
greatest component of a chemical analysis of food - answer-water
an organic compound can be defined as: - answer-a substance or
molecule containing carbon
a nutrient deficiency can be detected in its earliest stages by -
answer-lab tests of urine and blood samples
what is the best method for obtaining diet info for a large nutrition
survey? - answer-food frequency
the 6 major classes of nutrients - answer-carbohydrates, lipids (fats),
protein, vitamins, minerals, and water
T/F a food composition table can be used to determine the amount of
iron actually absorbed by the body from a serving of liver consumed -
answer-False
what nutrient source yields more energy than 4 kcalries per gram -
answer-fats (plant fats specifically)
what is an example of a micronutrient - answer-iron
,what is the ADMR for fat - answer-20-35%
what is the ADMR for carbs? - answer-45-65%
what is the ADMR for protein? - answer-10-35%
what is an example of an anthropometric measurement? -
answer-body weight or height
what type of deficiency is caused by inadequate absorption of a
nutrient? - answer-secondary
a case-control study is carried out to determine the relationship
between diet and colon cancer. the results indicate that subjects with
high cholesterol intake have 30% higher risk of cancer. Does this
result mean that dietary cholesterol causes colon cancer? - answer-no
not necessarily. it may be a case of guilt by association (the real cause
may not be cholesterol but some other food component associated
with cholesterol); also may be some error in diet assessment
an epidemiological study reveals that populations whose members
consume diets low in cereals have high incidence of prostate cancer.
does this result mean that cereals prevent prostate cancer? -
answer-no not necessarily. may be guilt by association (the real cause
of is inversely associated with cereals); also may be sources in
assessment or prostate cancer reports
discuss advantages and disadvantages of anecdotal studies as
means of investigating the dietary causes of disease -
answer-anecdotal studies may allow recognition of relationships
between diets and disease but only if they involve a large number of
, reports or similar symptoms; in many cases these studies are too
individual and can lead to other areas of research but not form
concrete details
why do intervention studies use control groups? why are they given
placebos? - answer-control groups ensure that treatment is actually
causing observed changes; placebo is given to counter the placebo
effect (the tendency of patients reporting to feel better after any sort of
treatment)
what is the meaning of a double-blind experiment? - answer-neither
subjects nor researchers know which subjects are in the control or
experimental group
what is the benefit of using a large sample size in an experiment? -
answer-the effect of chance variation is minimized
before publication in a reputable journal, what must the findings of a
study undergo? - answer-a peer review
the RDAs for protein, vitamins, and minerals are based on: -
answer-the needs of most healthy people
the RDA for energy is based on: - answer-the average requirement
the EARs can be appropriately used in: - answer-the planning of a
school lunch program
milk and milk products contribute significant amounts of: -
answer-calcium
