560E Nutr Assesment - my tests Flashcards
Which of the government guidelines is the nutrient intake level sufficient to meet the nutrient requirements of approximately 97% of people in a given sex/age group?
Recommended Dietary Allowance (RDA)
What measurement allows the nutritional quality of foods to be easily evaluated?
Nutrient density
What phenotypes have been identified with specific genetic polymorphisms?
Bone loss
Blood pressure
Inflammation
DRI’s were developed to address…
Chronic disease risk
Name 3 major themes in the 2010 Dietary Guidelines for Americans
Balancing calories to manage weight
Foods and nutrients to increase
Foods and food components to reduce
What is the most accurate statement describing the impact of single gene polymorphisms (SNPs) on phenotype?
Nutrients may alter the action of SNPs.
The primary purpose of the food exchange system is
To control energy consumption.
The New American Plate was developed by the American Institute for Cancer Research and the World Cancer Research Fund to emphasize ___________.
Plant foods
The UL for a particular nutrient describes…
the level above which the nutrient has a risk of adverse effects.
Nutritional Assessment methods include:
“ABCs”
Anthropometric
Biochemical
Clinical
Name 3 techniques for measuring dietary intake:
24-hour recall
Food diary
Diet History
A problem with the 24-Hour Recall is that
underreporting and/or overreporting can occur
An advantage of the Food Record over the 24-Hour Recall is that
it does not depend on memory
A limitation of Food Frequency Questionnaires is that
it may not represent usual foods or portion sizes chosen by respondents
A strength of the Diet History is that
it assesses usual nutrient intake
A well-known biological marker for verifying reported protein intake is
an analysis of nitrogen in a 24-hour urine specimen
True or False: An accurate dietary assessment can be the sole criterion on which to base nutritional recommendations for an individual.
FALSE
The fact that some nutrients are missing from the USDA database used in computerized dietary analysis systems
can result in falsely low nutrient values when evaluating dietary intake
Most high-quality computerized dietary analysis systems contain food composition data from
USDA plus non-USDA sources
The generally accepted normal range for BMI is
18.5-24.9
A waist circumference of 38 inches in an adult female
indicates an increased risk for type 2 diabetes
A disadvantage of assessing weight with BMI is that
BMI can be elevated for reasons other than excess fat
A tricep skinfold measures
subcutaneous fat
A disadvantage of Bioelectrical Impedance is
• electrical current is transmitted most rapidly by fat.
• dehydration will overestimate fat mass.
• it is invasive to the patient.
• it is a slow procedure.
dehydration will overestimate fat mass.
