A Food Frequency Questionnaire (FFQ) is a dietary assessment tool used to evaluate an individual's typical food intake over a specific period, often weeks or months. It consists of a list of foods with questions regarding the frequency and portion size of consumption.
Example of a Food Frequency Questionnaire (FFQ) Section:
Fruit and Vegetables Section (for the past month)
| Food Item | Never | 1-3 times/month | Once/week | 2-4 times/week | Daily | Portion Size (Small, Medium, Large) |
|---|---|---|---|---|---|---|
| Apples (whole, slices) | ☐ | ☐ | ☐ | ☐ | ☐ | ☐ Small ☐ Medium ☐ Large |
| Bananas | ☐ | ☐ | ☐ | ☐ | ☐ | ☐ Small ☐ Medium ☐ Large |
| Carrots (cooked/raw) | ☐ | ☐ | ☐ | ☐ | ☐ | ☐ Small ☐ Medium ☐ Large |
| Leafy Greens (spinach, kale) | ☐ | ☐ | ☐ | ☐ | ☐ | ☐ Small ☐ Medium ☐ Large |
| Potatoes (boiled, mashed) | ☐ | ☐ | ☐ | ☐ | ☐ | ☐ Small ☐ Medium ☐ Large |
Key Components of an FFQ:
- Food Items: Specific foods or food groups listed.
- Frequency Options: Ranges from "Never" to "Daily" consumption.
- Portion Size: Optional section estimating how much of the food is consumed.
- Time Frame: Often covers the past month, three months, or a year.
Use Cases:
- Nutritional epidemiology studies.
- Assessing dietary patterns in relation to health outcomes.
- Monitoring dietary changes in intervention studies.
