Which option is used to determine nutrient needs?

• A. Food Frequency Questionnaire
• B. Diet Records
• C. Dietary Reference Intake
• D. Anthropometry

Answer: (C)

Determining nutrient needs relies on reference values established by nutrition scientists, and the Dietary Reference Intakes provide these standards. DRIs include components like the Estimated Average Requirement, the Recommended Dietary Allowance, the Adequate Intake, and the Tolerable Upper Intake Level. These values are tailored to factors such as age, sex, life stage, and pregnancy status, and they form the basis for judging whether an individual's usual intake is adequate and for planning diets for individuals and groups. In practice, comparing what a person eats to these reference values helps determine if their nutrient intake meets needs or if adjustments are needed.

Tools like a Food Frequency Questionnaire estimate how often foods are consumed to infer usual nutrient intake, but they do not define the official nutrient needs themselves. Diet records track exact intake over a period to estimate consumption, yet they also don’t establish the required levels. Anthropometry measures body size and composition, offering insight into nutrition status or risk but not directly specifying nutrient requirements.
