Abstract 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.

Abstract 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.

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.

Objective: To evaluate the health impact of current and alternative patterns of rice consumption in Chinese adult men (40–79 years of age).Methods: We applied a risk–benefit assessment (RBA) model that took into account the health effects of selenium (Se), cadmium (Cd), and inorganic arsenic (i-As). The health effects included the prevention of prostate cancer associated with exposure to Se, and an increased risk of lung, bladder, and skin cancer for i-As and chronic kidney disease (CKD) for Cd. We defined the baseline scenario (BS) as the current individual mean daily consumption of rice in the population of interest and two alternative scenarios (AS): AS1 = 50 g/day and AS2 = 200 g/day. We estimated the health impact for different age groups in terms of change in Disability-Adjusted Life Years (ΔDALY).Results: The BS of rice consumption was 71.5–105.4 g/day in different age groups of adult men in China. We estimated that for AS1, the mean ΔDALY was −2.76 to 46.2/100,000 adult men of 40–79 years old. For AS2, the mean ΔDALY was 41.3 to 130.8/100,000 individuals in this population group.Conclusion: Our results showed that, based on associated exposure to selenium, cadmium, and i-As in rice, the current consumption of rice does not pose a risk to adult men in China. Also, a lower (50 g/day) or higher (200 g/day) rice consumption will not bring larger beneficial effects.

One of the challenges in quantitative risk-benefit assessment (RBA) of foods is the choice of approach for health effect characterization to estimate the health impact of dietary changes. The purpose of health effect characterization is to describe an association between intake of a food or food component and a health effect in terms of a dose-response relationship. We assessed the impact of the choice of approach for health effect characterization in RBA in two case studies based on substitution of (i) white rice by brown rice and (ii) unprocessed red meat by vegetables. We explored this by comparing the dose-response relations linking a health effect with (i) a food component present in the food, (ii) a food based on non-specified substitution analyses, and (iii) a food based on specified substitution analyses. We found that the choice of approach for health effect characterization in RBA may largely impact the results of the health impact estimates. Conducting the calculations only for a food component may neglect potential effects of the food matrix and of the whole food on the diet-disease association. Furthermore, calculations based on associations for non-specified substitutions include underlying food substitutions without specifying these. Data on relevant specified substitutions, which could reduce this type of bias, are unfortunately rarely available. Assumptions and limitations of the health effect characterization approaches taken in RBA should be documented and discussed, and scenario analysis is encouraged when multiple options are available.

Risk-benefit Assessment (RBA) is an emerging methodology in the area of Food and Nutrition that offers a simultaneous evaluation of both risks and benefits linked to dietary choices. Communication of such research to consumers may present a challenge due to the dual nature of RBA. We present a case study of a communication strategy developed for the NovRBA-project. The NovRBA-project (Novel foods as red meat replacers—an insight using Risk Benefit Assessment methods) performed a risk-benefit assessment to evaluate the overall health impact of substituting red meat (beef) by a novel food (house cricket), considering the microbial, toxicological and nutritional characteristics of the respective dietary choices. A literature review of risk perceptions and acceptance of beef and insects as food formed the basis of the communication strategy for the study's results, drawing on environmental and emotional as well as health-related motivations to consume or avoid either food and considering the sociodemographic characteristics of likely consumers. Challenges and future directions for consumer protection organizations communicating findings of risk-benefit analyses on food safety are discussed.

Abstract Human biomonitoring (HBM) is recognized as an important tool to assess the Human exposure to chemicals, contributing to describe trends and patterns of exposure over time and to identify population groups that could be under risk. Natural chemicals as mycotoxins, fungi metabolites that produce toxic effects in humans, are important compounds that could be found in foods usually consumed worldwide in a daily basis. Mycotoxins as aflatoxins (AFTs) are genotoxic, carcinogenic and immunosuppressive compounds. Hepatocellular carcinoma (HCC) is one of their main health toxic effects and is the third leading cause of cancer deaths worldwide. In Portugal, scarce data are available regarding exposure to AFTs and none previous study used HBM data to characterize comprehensively the burden associated to this exposure. In the scope of the National Food, Nutrition, and Physical Activity Survey of the Portuguese General Population (2015-2016), 24h-urine samples from 94 participants were analyzed by liquid chromatography-mass spectrometry (LC-MS/MS) for the simultaneous determination of AFTs (B1, B2, G1, G2, M1). A model was developed to estimate the health impact of the exposure of Portuguese population to aflatoxins, estimating the number of cases of HCC and DALYs attributed to AFTs exposure. AFTs were detected in 12.8% (AFB1), 16.0% (AFB2) and 19.1% (AFM1) of the 24h-urine samples. The estimated number of extra cases of HCC attributed to this exposure ranged from 17 to 65 cases/year; the associated DALYs for the Portuguese population ranged from 284 to 1802 years. The present study generated, for the first time and within a HBM study, reliable data regarding the exposure of the Portuguese population to AFTs. These data were crucial to characterize the health impact associated to AFTs exposure and to support risk managers to establish preventive policy measures that contribute to ensure the public health protection. Key messages Portuguese population is exposed to aflatoxins, chemical food contaminants that may be harmful (carcinogenic, immunotoxic, mutagenic, teratogenic, hepatotoxic) to humans. Human biomonitoring studies provide realistic data on internal exposure at individual level, contributing to a more accurate estimation of the burden derived from this exposure.

An optimal fatty acid (FA) profile during pregnancy, especially docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), is essential for the health of the mother and child. Our aim was to identify the socioeconomic and maternal lifestyle factors associated with serum FA concentration in pregnant women. A longitudinal study was conducted on 479 pregnant women, who were assessed during the first (T1) and third (T3) trimesters of pregnancy. Data on maternal characteristics, food consumption, and lifestyle were collected. Serum FA concentrations were analysed by a gas chromatography–mass spectrometry combination. The multiple linear regression showed that high educational level and older age were significantly associated with higher EPA and DHA concentrations and lower values of n-6/n-3 and arachidonic acid (AA)/EPA in T1 and/or T3. Regarding diet—fish and seafood consumption increased EPA concentration and reduced n-6/n-3 and AA/EPA values in both trimesters, whereas its consumption increased DHA concentration only in T1. Smoking was associated with lower DHA concentration in T1 and higher values of n-6/n-3 ratio in both trimester. Overweight and obesity were associated with higher values of n-6/n-3 ratio and AA/EPA ratio in T1. A statistically non-significant association was observed with saturated fatty acids (SFA) and monounsaturated fatty acids (MUFA). In conclusion, high educational levels, older age, fish, seafood consumption, and/or non-smoking, are factors that influence better omega-3 polyunsaturated fatty acid (n-3 PUFA) profile in both trimesters of pregnancy. Further research is needed to go in-depth into these findings and their health consequences.

Regulatory policies on drugs have a major impact on patient safety and survival. Some pharmaceutical companies employ all possible methods to achieve maximum sales in relation to the monopoly of their patented drugs, leading sometimes to irregularities and illegal activities. Misinformation on the orphan drug deferasirox has reached the stage of criminal investigations and fines exceeding USD 100 million. Additional lawsuits of USD 3.5 billion for damages and civil fines were also filed by the FBI of the USA involving deferasirox and mycophenolic acid, which were later settled with an additional fine of USD 390 million. Furthermore, a USD 345 million fine was also settled for bribes and other illegal overseas operations including an EU country. However, no similar fines for illegal practises or regulatory control violations have been issued in the EU. Misconceptions and a lack of clear guidelines for the use of deferasirox in comparison to deferiprone and deferoxamine appear to reduce the effective treatment prospects and to increase the toxicity risks for thalassaemia and other iron loaded patients. Similar issues have been raised for the activities of other pharmaceutical companies promoting the use of new patented versus generic drugs. Treatments for different categories of patients using new patented drugs are mostly market driven with no clear safeguards or guidelines for risk/benefit assessment indications or for individualised effective and safe optimum therapies. There is a need for the establishment of an international organisation, which can monitor and assess the risk/benefit assessment and marketing of drugs in the EU and globally for the benefit of patients. The pivotal role of the regulatory drug authorities and the prescribing physicians for identifying individualised optimum therapies is essential for improving the survival and safety of millions of patients worldwide.
