Summary

A cross-sectional study with repeated measurements among healthy Danish adults to assess the validity and reproducibility of a self-administered 7-day web-based dietary assessment tool, myfood24® tested against objective biomarkers.

Detailed description

Healthy volunteers (age 35-70 yrs; BMI 22-32) will be recruited for the study. Informed consent will be obtained and participants will complete a self-administered web-based 7-day 24-hour dietary recall tool (myfood24®).Validity of this dietary registration tool will be assessed by comparing the estimated intake of selected nutrients (protein, energy) and selected food groups (fruit and vegetables, whole grain, coffee, alcoholic beverages) against objective biomarkers obtained from a 24-hour urine sample, through a measurement of resting energy metabolic rate, and from a fasting blood sample, respectively. Reproducibility will be assessed by comparison of the results from two self-administered web-based 7-day 24-hour dietary recalls obtained 4 weeks (± 1 weeks) apart.
