Calystegines are Potential Urine Biomarkers for Dietary Exposure to Potato Prod...
Beckmann, M; Lloyd, AJ; Wilson, T; Torres, D; Goios, AC; Willis, ND; Lyons, L; Phillips, H; Mathers, JC; Nash, RJ; Sharp, H; Draper, J.Scope: Metabolites derived from specific foods present in urine samples can provide objective biomarkers of food intake (BFIs). This study investigated the possibility that calystegines (a class of iminosugars) may provide BIFs for potato (Solanum tuberosum L.) product exposure. Methods and results: Calystegine content is examined in published data covering a wide range of potato cultivars. Rapid methods are de...

Challenges Associated With the Design and Deployment of Food Intake Urine Bioma...
Beckmann, M; Wilson, T; Lloyd, AJ; Torres, Duarte; Góios, A.; Willis, ND; Lyons, L; Phillips, H; Mathers, JC; Draper, JImprovement of diet at the population level is a cornerstone of national and international strategies for reducing chronic disease burden. A critical challenge in generating robust data on habitual dietary intake is accurate exposure assessment. Self-reporting instruments (e.g., food frequency questionnaires, dietary recall) are subject to reporting bias and serving size perceptions, while weighed dietary asses...

Validation of a New Software eAT24 Used to Assess Dietary Intake in the Adult P...
Goios, AC; Severo, M; Lloyd, AJ; Magalhães, V; Lopes, C; Torres, DObjective: The aim of the current study was to evaluate the accuracy of the new software eAT24 used to assess dietary intake in the National Food, Nutrition and Physical Activity Survey (IAN-AF) against urinary biomarkers: N (nitrogen), K (potassium) and Na (sodium). Design: We conducted a cross-sectional study. Two non-consecutive 24-h dietary recalls (24-HDR) were applied, and a 24-h urine sample was collecte...
