A food frequency questionnaire differs from a 24-hour recall in what way:
  1. A food frequency questionnaire does not inquire about portion sizes.

  3. A food frequency questionnaire allows open-ended responses.
  4. A food frequency questionnaire always asks about the same types of foods.
Explanation
Answer: B - A food frequency questionnaire differs from a 24-hour recall because it does not ask about typical meal patterns. A food frequency questionnaire asks about intakes of different types of foods and usual portion sizes over time, and does not allow open-ended responses. The types of foods asked about on a food frequency questionnaire may be changed to reflect the population of interest.
