An online, semi-quantitative Food Frequency Questionnaire (FFQ) provides reproducible estimates of nutrient and food group intake and demonstrates moderate agreement with a 4-day weighed food record (WFR) for assessing energy and energy-adjusted nutrient intakes in healthy adults.
If you need to track your diet online, a well-designed Food Frequency Questionnaire (FFQ) that uses pictures for portion sizes is a reliable tool. It gives results very similar to writing down everything you eat for 4 days (weighed food record), making it a practical choice for long-term dietary tracking without the burden of daily weighing.
The results demonstrate that the online Food4Me FFQ is reproducible for assessing nutrient and food group intake and has moderate agreement with the 4-day WFR for assessing energy and energy-adjusted nutrient intakes. The Food4Me FFQ is a suitable online tool for assessing dietary intake in healthy adults.
Why this rating
Study uses a robust design with test-retest reproducibility and validation against a gold-standard WFR in a healthy adult population.
