- Benefits of dietary fibre to human health: study from a multi-country platformPublication . Guiné, Raquel; Duarte, João; Ferreira, Manuela; Correia, Paula; Leal, Marcela; Rumbak, Ivana; Baric, Irena; Komes, Drazenka; Satalic, Zvonimir; Saric, Marijana Matek; Tarcea, Monica; Fazakas, Zita; Jovanoska, Dijana; Vanevski, Dragoljub; Vittadini, Elena; Pellegrini, Nicoletta; Szucs, Viktória; Harangozó, Júlia; EL-Kenawy, Ayman; EL-Shenawy, Omnia; Yalçin, Erkan; Kösemeci, Cem; Klava, Dace; Straumite, EvitaPurpose: Because dietary fibre has been recognized as a major ally to the maintenance of a healthy body as well as to help against the development of some chronic diseases, this work aimed at studying the level of knowledge of a relatively wide range of people about the health effects related to the ingestion of dietary fibre in appropriate dosages. Methodology: A descriptive cross-sectional study was undertaken on a non-probabilistic sample of 6010 participants. The data were collected from 10 countries in 3 different continents (Europe, Africa and America) and measured the level of knowledge regarding different health benefits from dietary fibre. The questionnaires were applied by direct interview after verbal informed consent. Findings: The results obtained considering the general level of knowledge revealed a considerable degree of information about the benefits of fibre (average score of 3.54±0.5, on a scale from 1 to 5). There were significant differences between genders (p<0.001), with higher average score for women, and also for level of education (p<0.001), with higher score for university level. The living environment also showed significant differences (p<0.001), with people living in urban areas showing a higher degree of knowledge. Also for countries the differences were significant (p<0.001), with the highest score obtained for Portugal (3.7), and the lowest for Croatia, Italy, Latvia, Macedonia and Romania (3.5). However, despite these differences, the results showed that for all the countries the degree of knowledge was good (above 3.5), corresponding to a minimum level of knowledge of 70%. Originality/Value: This work is considered important due to the wide coverage, including so many countries inclusive with different social and cultural settings. The study allowed concluding that, in general, the participants in the study were quite well informed about the benefits of dietary fibre for the improvement of human health, regardless of gender, level of education, living environment or country. This finding is very relevant considering the diversity of people that composed the sample and reinforces the necessity of continuing with educational policies aimed at providing the general population with the knowledge that might help them make appropriate food choices.
- Cultural dimensions associated with food choice: A survey based multi-country studyPublication . Djekic, Ilija; Bartkiene, Elena; Szűcs, Viktória; Tarcea, Monica; Klarin, Ivo; Černelić-Bizjak, Maša; Isoldi, Kathy; EL-Kenawy, Ayman; Ferreira, Vanessa; Klava, Dace; Korzeniowska, Małgorzata; Vittadini, Elena; Leal, Marcela; Frez-Muñoz, Lucia; Papageorgiou, Maria; Guiné, RaquelThe aim of this research was to analyze motivations behind food choices from a cross-cultural perspective. It presents results derived from a multi-country study associated with Hofstede's cultural dimensions. A total of 11,919 respondents from 16 countries took part in this research. Two groups of statements were included in the survey: ‘economic & availability motivations' and ‘social & cultural motivations'. Six Hofstede's cultural dimensions covered: Power Distance Index, Individualism–Collectivism Index, Masculinity–Femininity Index, Uncertainty Avoidance Index, Term Orientation Index and Indulgence Restraint Index. This study confirmed that different cultural aspects have influence on food choice. A cluster analysis revealed two clusters as follows: ‘attitudinal’ cluster comprising of 11 countries (57.7% % of the total sample) opposed to the ‘ambivalent’ cluster (47.3%) consisting of the remaining five countries. The results confirm a correlation between Hofstede's dimensions, specifically with individualistic, feminine and tolerant societies. Obtained results may be of interest for different food and gastronomy stakeholders shifting their food policies from a local to a cross-cultural perspective.
- EATMOT Project: Eating motivations in different parts of the world, and particularly in countries from the Mediterranean AreaPublication . Guiné, Raquel; Ferrão, Ana Cristina; Ferreira, Manuela; Correia, Paula; Cardoso, Ana Paula; Duarte, João; Rumbak, Ivana; Vittadini, Elena; Papageorgiou, Maria; EL-Kenawy, AymanThe EATMOT Project is a multinational study about different eating motivations, and that is being carried out in 18 countries. The project addresses several types of factors that are related to food choice and consumption patterns, and that may in some extent condition the eating motivations, namely health related factors; economic and availability aspects; emotional determinants; social, cultural and religious influences; marketing and advertising campaigns and finally environmental concerns. The study is based on a questionnaire that was prepared purposely for the project, and therefore adequate to evaluate the aspects that determine the objectives highlighted. The study is coordinated by Portugal and involves a team of about 70 researchers from 16 countries, distributed as follows: Argentina, Brazil and United States in the American continent; Egypt in African continent; and the remaining countries in Europe: Croatia, Greece, Hungary, Italy, Latvia, Lithuania, Netherlands, Poland, Portugal, Serbia, Slovenia and Romania. The collected results surpass 12 thousand cases and allow, among many other studies, characterizing the eating motivations in different parts of the world, including the Mediterranean surrounding countries or countries which are typically linked to the Mediterranean diet, specifically: Croatia, Egypt, Italy, Greece or Portugal.
- Influence of sociodemographic factors on eating motivations – modelling through artificial neural networks (ANN)Publication . Guiné, Raquel; Ferrão, Ana Cristina; Ferreira, Manuela; Correia, Paula; Mendes, Mateus; Bartkiene, Elena; Szűcs, Viktória; Tarcea, Monica; Sarić, Marijana Matek; Černelič-Bizjak, Maša; Isoldi, Kathy; EL-Kenawy, Ayman; Ferreira, Vanessa; Klava, Dace; Korzeniowska, Małgorzata; Vittadini, Elena; Leal, Marcela; Frez-Muñoz, Lucia; Papageorgiou, Maria; Djekić, IlijaThis study aimed at investigating the influence of some sociodemographic factors on the eating motivations. A longitudinal study was carried conducted with 11960 participants from 16 countries. Data analysis included t-test for independent samples or ANOVA, and neural network models were also created, to relate the input and output variables. Results showed that factors like age, marital status, country, living environment, level of education or professional area significantly influenced all of the studied types of eating motivations. Neural networks modelling indicated variability in the food choices, but identifying some trends, for example the strongest positive factor determining health motivations was age, while for emotional motivations was living environment, and for economic and availability motivations was gender. On the other hand, country revealed a high positive influence for the social and cultural as well as for environmental and political and also for marketing and commercial motivations.
- Knowledge about dietary fibre: a fibre study frameworkPublication . Guiné, Raquel; Ferreira, Manuela; Correia, Paula; Duarte, João; Leal, Marcela; Rumbak, Ivana; Barić, Irena C.; Komes, Drazenka; Satalić, Zvonimir; Sarić, Marijana M.; Tarcea, Monica; Fazakas, Zita; Jovanoska, Dijana; Vanevski, Dragoljub; Vittadini, Elena; Pellegrini, Nicoletta; Szűcs, Viktória; Harangozó, Júlia; EL-Kenawy, Ayman; EL-Shenawy, Omnia; Yalçın, Erkan; Kösemeci, Cem; Klava, Dace; Straumite, EvitaThe objective of this work was to study the degree of knowledge about dietary fibre (DF), as influenced by factors such as gender, level of education, living environment or country. For this, a descriptive cross-sectional study was undertaken on a non-probabilistic sample of 6010 participants from 10 countries in different continents (Europe, Africa and America). The results showed that the participants revealed on average a positive but still low global level of knowledge, which alerts for the need to take some actions to further inform the population about DF and its role as a component of a healthy diet. The results also indicated differences between genders, levels of education, living environments and countries. The highest level of knowledge was revealed by the participants from female gender, with higher education and living in urban areas. Concerning the country, the best informed were the participants from Romania, followed by those from Portugal and Turkey while the least informed were from Egypt.
- Motivation for health behaviour: A predictor of adherence to balanced and healthy food across different coastal Mediterranean countriesPublication . Ljubičić, Marija; Sarić, Marijana Matek; Klarin, Ivo; Rumbak, Ivana; Barić, Irena Colić; Ranilović, Jasmina; EL-Kenawy, Ayman; Papageorgiou, Maria; Vittadini, Elena; Bizjak, Maša Černelič; Guiné, RaquelThis cross-sectional study aimed to assess perceptions of healthy food and motivation for health behaviour (MHB) in different Mediterranean countries. Multiple linear regression was used to identify the association between perception of healthy food and MHB in different countries. The highest MHB was observed in Portugal (median 38.0; IQR 7.0) and the lowest in Greece (median 34.0; IQR 8.0). Compared to Portuguese respondents, respondents from Croatia (ß=0.35; p < 0.001), Egypt (ß=0.24; p < 0.001), and Greece (ß=0.10; p < 0.001) had a higher probability of a better perception of healthy food. Slovenia respondents had reduced perception of healthy food (ß=-0.10; p < 0.001) and MHB (ß=-0.22; p < 0.001), despite higher adherence to a healthy diet (ß=0.22; p < 0.001). Lifestyle habits, such as physical exercise, showed a weak association with MHB (ß=0.14; p < 0.001) and adherence to healthy food (ß=0.18; p < 0.001). The presence of most chronic diseases was negatively associated with MHB. The association between the perception of healthy food, MHB, and adherence to a balanced and healthy diet across different countries could be useful for implementing strategies to promote healthy eating and prevent chronic diseases.
- Study about Food Choice Determinants According to Six Types of Conditioning Motivations in a Sample of 11,960 ParticipantsPublication . Guiné, Raquel; Bartkiene, Elena; Szűcs, Viktória; Tarcea, Monica; Ljubičić, Marija; Černelič-Bizjak, Maša; Isoldi, Kathy; EL-Kenawy, Ayman; Ferreira, Vanessa; Straumite, Evita; Korzeniowska, Małgorzata; Vittadini, Elena; Leal, Marcela; Frez-Muñoz, Lucia; Papageorgiou, Maria; Djekić, Ilija; Ferreira, Manuela; Correia, Paula; Cardoso, Ana Paula; Duarte, JoãoMany aspects linked to personal characteristics, society and culture constitute some of the motivators that drive food choice. The aim of this work was to determine in what extent the eating behaviors of individuals are shaped by six different types of determinants, namely: health, emotions, price and availability, society and culture, environment and politics, and marketing and commercials. This is a descriptive cross-sectional study, involving a non-probabilistic sample of 11,960 participants from 16 countries. The objective of this work was to validate the questionnaire, so as to make it suitable for application in different contexts and different countries. For that, six scales were considered for validation by confirmatory factor analysis with structural equation modelling. The obtained results showed that the six individual scales evaluated presented good or very good fitting indices, with saturation in goodness-of-fit index in all cases. The values of chi-square ratio were 6.921 (for health), 0.987 (environment), 0.610 (emotions) and 0.000 in the remaining cases (convenience, society, marketing). Furthermore, the fit was perfect, with saturation for all indices, in three of the six models (convenience, society and marketing). The results of this wok allowed the validation of the six scales, and the assessing of different types of factors that can influence food choices and eating behaviors, namely in the categories: health, emotions, price and availability, society and culture, environment and politics, and marketing and commercials.
- Study about some environmental factors that determine people’s food choices in 16 different countriesPublication . Guiné, Raquel; Ferreira, Manuela; Correia, Paula; Leal, Marcela; Ferreira, Vanessa; Rumbak, Ivana; EL-Kenawy, Ayman; Papageorgiou, Maria; Szucs, Viktória; Vittadini, Elena; Klava, Dace; Bartkiene, Elena; Munoz, Lucia; Korzeniowska, Malgorzata; Tarcea, Monica; Djekic, Ilija; Bizjak, Masa; Isoldi, KathyIn the ambit of the multinational project EATMOT undertaken in 16 countries (Argentina, Brazil, Croatia, Egypt, Greece, Hungary, Italy, Latvia, Lithuania, Netherlands, Poland, Portugal, Romania, Serbia, Slovenia and United States of America) a study was undertaken to evaluate the motivations for food choices as influenced by variables linked to sustainability. In this way aspects related with minimization of transportation and storage of food products, minimization of package or use of eco-materials, respect for animal’s rights and policies of recovery of food surplus were studied. The food sector is a very important one and greatly contributes to the pressure over the ecosystems, either because a great amount of food is produced, many times in intensive regimens, to feed humans on earth or because those foods are nowadays traded all over the world, contributing for the increase of the ecological footprint, and most especially if the transportation requires refrigeration systems. Hence, nowadays consumers may be aware of these problems and condition some of their food choices to these aspects. The research was undertaken by means of a questionnaire survey on nearly 12 thousand participants, from the 16 countries cited above. Briefly, the results indicated that, in general the concerns with environment and sustainability are important for most of the participants. Specifically, 55.2% preferably choose foods form the season and 49.15 prefer to buy local foods. About half of the participants (50.4%) opt for foods that comply with sustainable processing and packaging and the minimal usage of packaging is important to 49.1%. While a great majority, 70.7% try to avoid food waste at home, when it to comes to frequenting restaurants that do not have a recovery policy of food surplus the percentage is much lower, only 18.6%. The animal´s rights are a conditioning factor for food choice for about half of the participants, 49.8%. Still, it was observed that many of the participants did not manifest their opinion, with a percentage varying between 17.2 and 46.7%. These findings are important to understand the level of commitment of the general population around the world with sustainability factors determining their food choices and on the other hand show that there is still an important part of the population that do not take care about sustainability aspects when buying or consuming food, which something that we do several times everyday and year after year.
