Cereal-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 beneficial 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.
“RiskBenefit4EU ‐ Partnering to strengthen the risk‐benefit assessment within EU using a holistic approach” was a knowledge transfer project funded by the European Food Safety Authority (EFSA) that integrated a multidisciplinary team from Portugal, Denmark and France. This project aimed to strengthen the EU capacity to assess risks and benefits associated with human food consumption, considering the fields of toxicology, microbiology and nutrition. To train the recipient partners from Portugal on Risk‐Benefit Assessment (RBA), a capacity‐building program was implemented, including three main activities: theoretical training on RBA concepts; hands‐on training applying concepts to a case‐study using methods and tools displayed; and scientific missions to provide advanced training in specific domains of RBA. The developed RBA strategy was applied to a case study focusing on the RBAof the consumption of cereal‐based products by Portuguese young children. Risks due to aflatoxins, Bacillus cereus, sodium and free sugars, were evaluated, as well as the benefit of fibreintake. Five different scenarios of infant cereals and/or breakfast cereals consumption were considered, and the assessment showed that moving from the current consumption to the considered alternative scenarios wouldresult in a gain of healthy‐life years. The RiskBenefit4EU project applied a collaborative method to train a new team to perform RBAs of foods and face the challenge of cooperation between experts from different disciplines. During the process of capacity building, a movement from conceptual knowledge towards action was an essential step to effectively increase performance. The developed framework facilitated the case‐study accomplishment and contributed to build a shared and harmonized RBA approach and culture. The suggested strategy can now be re‐used to capacitate other teams in RBA,and can be considered as a basis to build upon.
Portugal 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) was 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 (DALYs). In the Portuguese population, about 11450 DALYs could be prevented each year if the fish/seafood consumption increased to a daily basis. However, such a scenario would result in 1398 extra DALYs considering the consumption by pregnant women and the respective risk on foetal 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 foetal neurodevelopment due to methylmercury exposure.
Background Fish/seafood consumption has health benefits, namely due to its omega-3 fatty acids levels and risks due to methylmercury contamination. This study aims to quantify the health impact of hypothetical scenarios of fish/seafood consumption through a risk-benefit assessment and provide support for recommendations, using Portuguese food consumption data. Methods We used data from the National Food, Nutrition and Physical Activity Survey 2015-2016 (n = 5811) to estimate the mean exposure to methylmercury and EPA+DHA in the current and alternative scenarios. Alternative scenarios were modelled using probabilistic approaches to reflect substitutions from the current consumption in the type of fish/seafood (predatory vs low-mercury species) or its frequency (1-7x/week). The overall scenarios’ impact was quantified using Disability-Adjusted Life Years (DALYs). Results About 14% of the Portuguese population exceeds the methylmercury tolerable weekly intake, and this prevalence is higher among small children (36.6%). Nevertheless, if the fish/seafood consumption increased to once a day, ≈11450 DALYs could be prevented each year. However, such a scenario would result in higher risk for pregnant women (1398 extra DALYs). Moreover, excluding predatory species consumption resulted in small but significant health gains (-1078 DALYs). Conclusions For the general population, the maximum health gains are obtained by consuming fish/seafood up to 7x/week, but among children and pregnant women, the frequency should be limited to 3-5x/week. All population should preferably choose non-predatory species. Key messages Daily fish consumption results in the highest overall populational health gain, but children and pregnant women need to limit it to 3-5x/week, due to methylmercury exposure.
