A 12-item, 5-minute online diet quality assessment (WELL Diet Score) yields scores significantly correlated with established, lengthy 127-item Food Frequency Questionnaires (AHEI-2010), validating its use for rapid, large-scale diet quality assessment.
If you need to track your diet for a long-term health goal or research study but hate filling out long forms, use a validated short-form diet tracker. This study shows that a 12-question survey can accurately reflect your overall diet quality just as well as a much longer, more tedious questionnaire, making it easier to stick with the habit of tracking.
The two scores were significantly correlated (r = .69; p < .0001)... In summary, the WELL Diet Score, derived from 12 small diet-related items that can be completed in 5 min, was significantly positively correlated with the AHEI-2010 derived from the lengthy 127-item FFQ, suggesting the potential utility of the WELL Diet Score in future large-scale studies.
