This study aimed to assess the extent which first-morning void (FMV) urine samples can estimate sodium and potassium excretion compared with 24-hour (24-h) at population level. We conducted a cross-sectional collecting (FMV 24-h) two non-consecutive 24-h dietary recalls in sub-sample from Portuguese IAN-AF sampling frame. Six predictive equations were used FMV samples. Pearson correlation coefficients calculated compare association between collections. Cross-classifications into tertiles...
Abstract Objective: The aim of the current study was to evaluate accuracy new software eAT24 used assess dietary intake in National Food, Nutrition and Physical Activity Survey (IAN-AF) against urinary biomarkers: N (nitrogen), K (potassium) Na (sodium). Design: We conducted a cross-sectional study. Two non-consecutive 24-h recalls (24-HDR) were applied, urine sample collected. examined differences between estimates from measures, Pearson correlation coefficients calculated Bland–Altman...
Zearalenone and alternariol are mycotoxins produced by Fusarium Alternaria species, respectively, that present estrogenic activity consequently classified as endocrine disruptors. To estimate the exposure of Portuguese population to these two at a national level, modelling approach, based on data from 94 volunteers, was developed considering inputs: i) food consumption generated within National Food Physical Activity Survey; ii) human biomonitoring used assess referred mycotoxins. Six models...
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 iminosugars) may BIFs for potato (Solanum tuberosum L.) product exposure.Calystegine content is examined published data covering a wide range cultivars. Rapid methods are developed quantification cooked products and human using triple quadrupole mass spectrometry. The potential as BFIs consumption assessed...
Improvement of diet at the population level is a cornerstone national and international strategies for reducing chronic disease burden. A critical challenge in generating robust data on habitual dietary intake accurate exposure assessment. Self-reporting instruments (e.g., food frequency questionnaires, recall) are subject to reporting bias serving size perceptions, while weighed assessments unfeasible large-scale studies. However, secondary metabolites derived from individual foods/food...
Abstract Human biomonitoring (HBM) is recognized as an important tool to assess the exposure chemicals, contributing describe trends and patterns of over time identify population groups that could be under risk. Natural chemicals mycotoxins, fungi metabolites produce toxic effects in humans, are compounds found foods usually consumed worldwide a daily basis. Mycotoxins aflatoxins (AFTs) genotoxic, carcinogenic immunosuppressive compounds. Hepatocellular carcinoma (HCC) one their main health...
Abstract Mycotoxins constitute a relevant group of food contaminants with several associated health outcomes such as estrogenic, immunotoxic, nephrotoxic and teratogenic effects. Although scarce data are available in Portugal, human biomonitoring studies have been globally developed to assess the exposure mycotoxins at individual level. The present study concerned analysis 24h urine first-morning paired samples from 94 participants enrolled within scope National Food, Nutrition, Physical...
conclude about the presence of asthenization in study population.At same time, statistically significant differences were observed between Abay and Kurchum districts (p < 0.001), but it was not a matter fact for Borodulikha district, which did significantly differ from control Conclusions:The average fatigue rate groups could be interpreted as moderate that manifested poor tolerance physical mental stress, general weakness, reduced motivation any kind activity, fixation on unsatisfactory...
