- Consumo de alimentos à base de cereais pelas crianças portuguesas: uma avaliação de risco-benefícioPublication . Assunção, Ricardo; Boué, Géraldine; Alvito, Paula; Brazão, Roberto; Carmona, Paulo; Carvalho, Catarina; Correia, Daniela; Fernandes, Paulo; Lopes, Carla; Martins, Carla; Membré, Jeanne-Marie; Monteiro, Sarogini; Nabais, Pedro; Thomsen, Sofie T.; Torres, Duarte; Pires, Sara M.; Jakobsen, Lea S.De uma forma geral, o consumo de alimentos pode apresentar potenciais riscos e benefícios para os consumidores. Os alimentos à base de cereais, incluindo os cereais de pequeno-almoço e os cereais infantis, representam componentes importantes da dieta humana e estão entre os primeiros alimentos sólidos que são introduzidos na dieta. Estes alimentos constituem uma fonte importante de vários nutrientes, incluindo o sódio, fibras e açúcares livres, que podem estar associados a efeitos benéficos e adversos para a saúde. Simultaneamente, os alimentos à base de cereais podem também ser veículo de contaminantes químicos (por exemplo, micotoxinas) e microbiológicos (por exemplo, Bacillus cereus). As aflatoxinas, um grupo de micotoxinas que apresenta maior potencial tóxico, são frequentemente detetadas em cereais. No âmbito do projeto RiskBenefit4EU, o presente estudo teve como objetivo avaliar os riscos e os benefícios associados ao consumo de alimentos à base de cereais pelas crianças portuguesas. Os riscos (teores de aflatoxinas e B. cereus, sódio e açúcares livres) e os benefícios (teor de fibra) associados ao consumo de cereais de pequeno-almoço (CPA) foram comparados com aqueles associados ao consumo de cereais infantis (CI). Os resultados obtidos revelaram que a mudança do consumo atual para os cenários alternativos considerados (em especial para o consumo de cereais de pequeno-almoço com características semelhantes ao “Melhor CPA”) poderia resultar num ganho de anos de vida saudável.
- Deoxynivalenol exposure assessment through a modelling approach of food intake and biomonitoring data – A contribution to the risk assessment of an enteropathogenic mycotoxinPublication . Martins, Carla; Torres, Duarte; Lopes, Carla; Correia, Daniela; Goios, Ana; Assunção, Ricardo; Alvito, Paula; Vidal, Arnau; De Boevre, Marthe; De Saeger, Sarah; Nunes, CarlaDeoxynivalenol (DON), an enteropathogenic mycotoxin produced by Fusarium species, is usually associated with adverse health outcomes such as gastrointestinal diseases and immunotoxicity. To estimate DON exposure of the Portuguese population at national level, a modelling approach, based on data from 94 Portuguese volunteers, was developed considering the inputs of the food consumption data generated within the National Food and Physical Activity Survey and the human biomonitoring data used to assess the exposure to DON. Ten models of association between DON urinary biomarkers and food items (pasta, cookies, biscuits, sweets, bread, rusks, nuts, oilseeds, beer, meat, milk) were established. Applying the most adequate model to the consumption data (n = 5811) of the general population, the exposure estimates of the Probable Daily Intake revealed that a fraction (0.1%) of the Portuguese population might exceed the Tolerable Daily Intake defined for DON. The analysis stratified by age revealed children (3.2%) and adolescents (6.0%) are more likely to exceed the Tolerable Daily Intake for DON. Although the unavoidable uncertainties, these results are important contributions to understand the exposure to this mycotoxin in Portugal, to assess the associated risk and the potential public health consequences.
- Exposição a metilmercúrio e consumo de pescado: emissão de recomendações nacionais, 2023Publication . Fernandes, Paulo; Afonso, Cláudia; Bico, Paula; Bandarra, Narcisa; Borges, Marta; Carmona, Paulo; Carvalho, Catarina; Correia, Daniela; Gonçalves, Susana; Lopes, Carla; Lourenço, Helena; Monteiro, Sarogini; Nabais, Pedro; Oliveira, Luísa; Santiago, Susana; Severo, Milton; Torres, Duarte; Dias, Maria GraçaConsiderando que o consumo de pescado é uma fonte importante de exposição ao metilmercúrio, a Comissão Europeia recomendou aos Estados- -membros que estabelecessem recomendações para o seu consumo. Assim, tendo sido criado um grupo de trabalho, é objetivo deste artigo apresentar o trabalho desenvolvido para a elaboração das recomendações de consumo de pescado adaptadas à população portuguesa, tendo em conta o padrão nacional de consumo de peixe e as espécies consumidas. A definição das recomendações assentou na realização de um estudo de avaliação de risco-benefício associado ao consumo de pescado. Esta metodologia permitiu identificar dois grupos populacionais sujeitos a recomendações distintas: para a população em geral recomenda-se uma frequência de consumo de 4 a 7 vezes por semana e, para a população vulnerável, uma frequência de 3 a 4 vezes por semana das espécies com médio e baixo teor de mercúrio, devendo ser evitado o consumo das espécies com elevado teor de mercúrio. Estas recomendações foram divulgadas num evento público e deverão ser alvo de esforços adicionais para chegarem à população vulnerável, constituída por mulheres grávidas, mulheres a amamentar e crianças até aos 10 anos.
- Food Consumption Data as a Tool to Estimate Exposure to MycoestrogensPublication . Martins, Carla; Torres, Duarte; Lopes, Carla; Correia, Daniela; Goios, Ana; Assunção, Ricardo; Alvito, Paula; Vidal, Arnaud; De Boevre, M.; De Saeger, Sarah; Nunes, CarlaZearalenone 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 consumption data generated within the National Food and Physical Activity Survey; and ii) the human biomonitoring data used to assess the exposure to the referred mycotoxins. Six models of association between mycoestrogens urinary levels (zearalenone, total zearalenone and alternariol) and food items (meat, cheese, and fresh-cheese, breakfast cereals, sweets) were established. Applying the obtained models to the consumption data (n = 5811) of the general population, the median estimates of the probable daily intake revealed that a fraction of the Portuguese population might exceed the tolerable daily intake defined for zearalenone. A reference intake value for alternariol is still lacking, thus the characterization of risk due to the exposure to this mycotoxin was not possible to perform. Although the unavoidable uncertainties, these results are important contributions to understand the exposure to endocrine disruptors in Portugal and the potential Public Health consequences.

- Prevalence of general and abdominal obesity in Portugal: comprehensive results from the National Food, nutrition and physical activity survey 2015-2016Publication . Oliveira, Andreia; Araújo, Joana; Severo, Milton; Correia, Daniela; Ramos, Elisabete; Torres, Duarte; Lopes, Carla; by the IAN-AF ConsortiumBACKGROUND: This study includes, for the first time, estimates of general and abdominal obesity prevalence for all ages of the Portuguese population, using common standardized methodologies. Results are compared by sex, age groups, educational level and geographical regions. METHODS: Participants were a representative sample of the Portuguese population aged between 3 months and 84 years of age (n = 6553), enrolled in the National Food, Nutrition and Physical Activity Survey, 2015-2016. Objective anthropometric measurements included length/height, weight and body circumferences, performed according to standard procedures. Body mass index (BMI) was classified according to the World Health Organization (WHO) growth charts for children and adolescents, and WHO criteria for adults. Abdominal obesity was defined in adults as waist-hip ratio ≥ 0.85 in women or ≥ 0.90 in men. Prevalence estimates and 95% confidence intervals (95%CI) were weighted according to a complex sampling design, considering stratification by seven geographical regions and cluster effect for the selected Primary Health Care Unit. RESULTS: The national prevalence of obesity is 22.3% (95%CI: 20.5-24.0), significantly higher in women. Obesity prevalence is much higher in the elderly (39.2%, 95%CI. 34.2-44.2), while children and adolescents have the lowest prevalence around 8-9%. In a regression model, three knot points denoting an inflection of obesity prevalence across the life span were observed around 5, 15 and 75 years. The prevalence of pre-obesity at national level is 34.8% (95%CI: 32.9-36.7), higher in men, and almost 18% of children and 24% of adolescents have pre-obesity. The sex- and age-standardized prevalence of obesity ranged from 38.3% (95%CI: 34.6-42.1) to 13.1% (95%CI: 10.3-15.9) for the less and the most educated individuals, respectively. Although some geographical region disparities, obesity prevalence did not significantly differed across regions (p = 0.094). The national prevalence of abdominal obesity in adults is 50.5% (95%CI: 47.9-53.1), particularly high in the elderly (80.2%). CONCLUSION: Almost 60% of the general Portuguese population is obese or pre-obese. Women, elderly and less educated individuals present the highest obesity prevalence. Abdominal obesity, in particular, seems to be a relevant public health problem among the elderly men.
- Quantitative risk-benefit assessment of Portuguese fish and other seafood species consumption scenariosPublication . Carvalho, Catarina; Correia, Daniela; Severo, Daniel; Afonso, Cláudia; Bandarra, Narcisa; Gonçalves, Susana; Lourenço, Helena; Dias, Maria da Graça; Oliveira, Luísa; Nabais, Pedro; Carmona, Paulo; Monteiro, Sarogini; Borges, Marta; Lopes, Carla; Torres, DuartePortugal has high fish/seafood consumption, which may have both risks and benefits. This study aims to quantify the net health impact of hypothetical scenarios of fish/seafood consumption in the Portuguese population using a risk-benefit assessment methodology. Consumption data from the National Food, Nutrition and Physical Activity Survey 2015-2016 (n 5811) were used to estimate the mean exposure to methylmercury and EPA + DHA in the current and the alternative scenarios considered. Alternative scenarios (alt) were modelled using probabilistic approaches to reflect substitutions from the current consumption in the type of fish/seafood (alt1: excluding predatory fishes; alt2: including only methylmercury low-level fishes) or in the frequency of weekly fish/seafood consumption (alt3 to alt6: 1, 3, 5 or 7 times a week, replacing fish/seafood meals with meat or others). The overall health impact of these scenarios was quantified using disability-adjusted life years (DALY). In the Portuguese population, about 11 450 DALY could be prevented each year if the fish/seafood consumption increased to a daily basis. However, such a scenario would result in 1398 extra DALY considering the consumption by pregnant women and the respective risk on fetal neurodevelopment. Our findings support a recommendation to increase fish/seafood consumption up to 7 times/week. However, for pregnant women and children, special considerations must be proposed to avoid potential risks on fetal neurodevelopment due to methylmercury exposure.
- Risk-Benefit Assessment of Cereal-Based Foods Consumed by Portuguese Children Aged 6 to 36 Months-A Case Study under the RiskBenefit4EU ProjectPublication . Assunção, Ricardo; Boué, Géraldine; Alvito, Paula; Brazão, Roberto; Carmona, Paulo; Carvalho, Catarina; Correia, Daniela; Fernandes, Paulo; Lopes, Carla; Martins, Carla; Membré, Jeanne-Marie; Monteiro, Sarogini; Nabais, Pedro; T. Thomsen, Sofie; Torres, Duarte; Pires, Sara; S. Jakobsen, LeaCereal-based foods, including breakfast (BC) and infant cereals (IC), are among the first solid foods introduced to infants. BC and IC are sources of macro and micronutrients that have bene ficial effects on health, but can also be sources of harmful chemical and microbiological contaminants and nutrients that may lead to adverse health effects at high consumption levels. This study was performed under the RiskBenefit4EU project with the aim of assessing the health impact associated with consumption of BC and IC by Portuguese children under 35 months. Adverse effects associated with the presence of aflatoxins, Bacillus cereus, sodium and free sugars were assessed against the benefits of fiber intake. We applied a risk–benefit assessment approach, and quantified the health impact of changes in consumption of BC and IC from current to various alternative consumption scenarios. Health impact was assessed in terms of disability-adjusted life years. Results showed that moving from the current consumption scenario to considered alternative scenarios results in a gain of healthy life years. Portuguese children can benefit from exchanging intake of IC to BC, if the BC consumed has an adequate nutritional profile in terms of fiber, sodium and free sugars, with levels of aflatoxins reduced as much as possible.
