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...
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...
Food Consumption Data as a Tool to Estimate Exposure to Mycoestrogens
Martins, C; Torres, D; Lopes, C; Correia, D; Goios, AC; Assunção, R; Alvito, P; Vidal, A; de Boevre, M; de Saeger, S; Nunes, CZearalenone and alternariol are mycotoxins produced by Fusarium and Alternaria species, respectively, that present estrogenic activity and consequently are classified as endocrine disruptors. To estimate the exposure of the Portuguese population to these two mycotoxins at a national level, a modelling approach, based on data from 94 Portuguese volunteers, was developed considering as inputs: i) the food consump...
