Which of the following methods provide qualitative data on diet?

Correct option is B

• Food frequency method is used in dietary assessment to gather qualitative data by recording how often different food items are consumed over a given period.
• It provides insights into patterns of food intake and dietary habits (qualitative) rather than exact quantities.
• In contrast, the 24-hour recall, weighment, and duplicate sample analysis collect quantitative measurements of dietary intake. (General nutrition methodology understanding)
