A - Estimated Average Requirement (ERA)
B - Adequate Intake (AI)
C - Tolerable Upper Intake Level

6

What is the most accurate statement describing the impact of single nucleotide polymorphisms (SNPs) on phenotype?

B - estimation based on weight
C - diet history
D - food diary

B - estimation based on weight

12

Underreporting and/or overreporting can occur with the 24-hour recall. TRUE or FALSE

TRUE

13

What is an advantage of the Food record/diary over the 24-hour recall?

FALSE

18

The fact that some nutrients are missing from the USDA data base used in computerized dietary analysis systems:

B - can result in falsely elevated nutrient values when evaluating dietary intake
C - can be corrected by analyzing additional days of intake
D - is not a problem for accurate dietary analysis

A - can result in falsely low nutrient values when evaluating dietary intake
