- Amino acid profile of foods from the Portuguese Total Diet Pilot StudyPublication . Motta, Carla; Matos, Ana Sofia; Soares, Ana; Gonzales, Gerard Bryan; Castanheira, Isabel; Cabral, Izunildo; Tavares, Nelson; Nicolai, MarisaThe amino acid content of foods commonly consumed by specific populations is rarely measured systematically, especially if we take into account the different ways that foods are usually processed or cooked. The objective of this study is to evaluate the amino acid profile of the representative foods on the Portuguese diet, with a particular focus on indispensable amino acids. We also aim to assess the amino acid intake of the population and the most common sources of amino acids within the Portuguese diet. To achieve these goals, the amino acid intake of Portuguese adults was assessed combining data of food consumption with the food analysis data from samples collected according to the Total Diet Study methodologies. Results of the amino acid profiles of food groups typically consumed in Portugal are reported in this paper. We found that red meat consumption is the most common source of amino acids of the Portuguese population, followed by white meat and fish. The main contribution of individual portions to the recommended intakes of essential amino acids were: cheese, 88%; red meat, 83%; fatty fish, 81% and seitan with 74%. This data could be used to show alternative amino acid sources within commonly consumed foods.
- Folates in quinoa (Chenopodium quinoa), amaranth (Amaranthus sp.) and buckwheat (Fagopyrum esculentum): Influence of cooking and maltingPublication . Motta, Carla; Delgado, Inês; Matos, Ana Sofia; Gonzales, Gerard Bryan; Torres, Duarte; Santos, Mariana; Chandra-Hioe, Maria V.; Arcot, Jayashree; Castanheira, IsabelEffects of processing on the contents of five folate vitamers in quinoa, amaranth and buckwheat were analysed using a trienzymatic extraction method followed by LC–MS/MS. Total folate (TF) content, corresponding to the sum of folic acid (FA), 5-methyltetrahydrofolate (5-MTHF) and 10-formyltetrahydrofolate (10-CHOTHF) expressed as folic acid equivalent, in raw quinoa, amaranth and buckwheat were 309 ± 8.07, 228 ± 24.2 and 153 ± 12.4 μg/100 g dw, respectively, being dominantly 5-MTHF. Boiling and steaming reduced the TF in amaranth by 58% and 22%, respectively, whereas up to a 10–15% increase was observed in quinoa. Boiling and steaming did not significantly alter the TF content in buckwheat although significant changes were observed in some individual folate vitamers. Malting, on the other hand significantly increased TF content in amaranth by 21% (276 ± 14.2 μg/100 g dw) and buckwheat by 27% (193 ± 20.0 μg/100 g dw), whereas no significant change in quinoa was observed. Based on the EFSA recommendations, a portion of amaranth and quinoa (either boiled, steamed or malted) may contribute up to more than 25% of the dietary reference value for folates, whereas buckwheat may contribute only 14% when cooked and 19% when malted. Results demonstrate that quinoa, amaranth and buckwheat are good sources of folates, regardless of processing.
- Nutrition remains a top priority in Ukraine despite the ongoing war: the fight against trans fatsPublication . Gonzales, Gerard Bryan; Fino Alberto da Motta, Carla Alexandra; Farrand, Clare; Habicht, Jarno; Kuriata, Olena; Phyo, Pyi Pyi; Skipalskyi, Andrii; Wickramasinghe, KremlinDespite the ongoing war, nutrition remains a top priority in Ukraine. In collaboration with the WHO, Ukraine remains steadfast in its mission to eliminate trans fats in the food supply as a measure to reduce non-communicable diseases in the country. Ukraine has passed legislation on the monitoring and regulation of trans fats in foods, and WHO has been supporting the country in building laboratory capacity to achieve this goal.
- Nutritional Characterization of Street Food in Urban Turkmenistan, Central AsiaPublication . Albuquerque, Gabriela; Sousa, Sofia; Lança de Morais, Inês; Gelormini, Marcello; Motta, Carla; Gonzales, Gerard Bryan; Ovezov, Azat; Damasceno, Albertino; Moreira, Pedro; Breda, João; Lunet, Nuno; Padrão, PatríciaObjective: Describing the availability and nutritional composition of the most commonly available street foods in Ashgabat, Turkmenistan. Methods: One hundred sixty-one street food vending sites (six public markets) were assessed, through a collection of data on vending sites’ characteristics and food availability, and samples of commonly available foods (21 homemade; 11 industrial), for chemical analysis. Results: Fruit, beverages, and food other than fruit were available in 6.8, 29.2, and 91.9% of all vending sites, respectively. Regarding the latter, 52.7% of the vending sites sold only homemade products (main dishes, snacks, cakes, biscuits and pastries, bread, ice-cream chocolate and confectionery, savory pastries and sandwiches), 37.2% only industrial (ice-cream, chocolate and confectionery, cakes, biscuits and pastries, snacks, bread and savory pastries) and 10.1% both. Homemade foods presented significantly higher total fat [homemade 11.6 g (range 6.6–19.4 g); industrial 6.2 g (range 4.0–8.6 g), p = 0.001], monounsaturated, polyunsaturated and trans-fat, and sodium and potassium content per serving. Industrial wafers presented the highest mean saturated (11.8 g/serving) and trans-fat (2.32 g/serving) content. Homemade hamburgers presented the highest mean sodium content (1889 mg/serving). Conclusions: Strategies to encourage the production and sales of healthier street foods, especially homemade, are needed to promote healthier urban food environments in urban Turkmenistan.
- Nutritional Composition of Ultra-Processed Plant-Based Foods in the Out-of-Home Setting: A Case-Study with Vegan BurgersPublication . Vellinga, Reina E.; Temme, Elisabeth H.M.; Rippin, Holly; Motta, Carla; Gonzales, Gerard Bryan; Farrand, Clare; Wickramasinghe, KremlinUltra-processed plant-based foods, such as plant-based burgers, have gained popularity and are perceived by consumers as a healthier and more environmentally sustainable alternative to animal-based foods. However, evidence regarding their nutritional profile and environmental sustainability is still evolving. To contribute to the understanding of the nutrient profile of ultra-processed plant-based foods in the out-of-home environment. Cities in four WHO European Member States were selected for study in a convenience sample across the regions of Amsterdam, Copenhagen, Lisbon, and London. Plant-based burgers available at selected out-of-home sites were randomly sampled. In total 41 plant-based burgers were lab-analyzed for their energy, macronutrients, amino-acids and minerals content per 100 g and per serving size. Descriptive data were used to summarize the nutritional composition per 100 g and serving size. The content per serving was compared to the appropriate reference values. The median energy content was 234 kcal/100 g (IQR = 50). Median macronutrient composition was 20.8 g/100 g (IQR = 5.7) carbohydrates and 3.5 g/100 g (IQR = 1.8) dietary fibre. Protein content was 8.9 g/100 g (IQR = 3.7) with low protein quality. The median total fat content was 12.0 g/100 g (IQR = 4.2), including 0.08 g (IQR = 0.05) TFA and 2.2 g (IQR = 2.3) SFA. The median sodium content was 389 mg/100 g (IQR = 113), equivalent to 2.7 g salt. When compared with reference values, the median serving of plant-based burgers (280 g) provided 31% of energy intake and contributed 17–28% of carbohydrates, 42% of dietary fibre, 40% of protein, and 48% of total fat including 26% of SFA. The burgers had low-quality protein. One serving provided 15–20% of the reference values for calcium, potassium, and magnesium, while higher contributions were found for zinc (30%), manganese (38%), phosphorus (51%), and iron (67%). Ultra-processed plant-based foods, such as plant-based burgers, provide protein, dietary fibre, and essential minerals. They also contain high levels of energy, sodium, and fatty acids. Despite their potential as a source of protein, the quality of protein in plant-based burgers is low. The multifaceted nutritional profile of plant-based burgers highlights the need for manufacturers to implement improvements to better support healthy dietary habits. These improvements should include reducing salt and fatty acids while also enhancing protein quality.
