Brief Summary

The aim is to determine whether the eNutri web application can effectively estimate the dietary intake of a UK older population. The eNutri FFQ65+ study will validate the eNutri online food frequency questionnaire (FFQ) using 100 adults aged 65+ years. The FFQ will be validated against an online 24-hour dietary recall system (Intake24) and its reproducibility will be evaluated by the completion of two FFQs within a 14-day interval. In addition, all participants will also be asked to provide dried blood spot (DBS) samples which will be analysed for key biomarkers of nutritional intake and health. Biomarker results will be compared to FFQ results to further validate the eNutri FFQ.

Retention: SAMPLES WITH DNA

Dried blood spots will be collected from participants but will not be used to extract DNA. The dried blood spots will be used to validate the FFQ against selected biomarkers such as markers of health (e.g. cholesterol) and markers of nutrient intake (e.g. carotenoids).
