• What itis:
• This type of FFQ includes both food
frequency and portion sizes.
Respondents are asked to report how
often they eat certain foods, as well as
estimate the portion size they typically
consume.
• Example:
• "How often do you eat apples? (Daily,
Weekly, Monthly, Never)" + "What
portion size do you usually eat? (Small,
Medium, Large)."
• Why it's used:
• Provides detailed dietary data, making
it useful for nutrient intake
estimation. This version is more
precise and is typically used in large-
scale epidemiological studies.

• Instructions:
• Please answer the following questions based on your usual
eating habits over the past month. For each food, mark how
often you typically eat it, and choose the portion size that
best matches the amount you usually consume.

CONCLUSION
•The Food FrequencyQuestionnaire (FFQ) is
a widely used dietary assessment tool that
evaluates an individual's usual food intake
over a specific period. It is particularly useful
in nutritional epidemiology for identifying
dietary patterns and their associations with
health outcomes. The FFQ is practical for
large-scale studies, cost-effective, and allows
for long-term dietary intake analysis.
•However, its reliance on self-reported data
may introduce recall bias and portion size
inaccuracies. Despite these limitations, the
FFQ remains a valuable method for assessing
dietary intake, especially when combined with
other nutritional assessment tools for greater
accuracy.
