- An Insight into the Level of Information about Sustainability of Edible Insects in a Traditionally Non-Insect-Eating Country: Exploratory StudyPublication . Guiné, Raquel P. F.; Florença, Sofia De Guiné E; Anjos, O.; Correia, Paula; Ferreira, Bruno; Costa, Cristina Amaro DaInsects have been reported as a possible alternative solution to help feed the growing world pop-ulation with less stress on the planet, thus contributing to the preservation of the environment and natural ecosystems. However, the consumption of edible insects (EIs), although culturally ac-cepted for some communities, is not readily accepted for others. Hence this work explores the lev-el of information that people in a traditionally non-insect-eating country have about the sustaina-bility issues related with EIs, and also some possible reasons that could motivate their consump-tion. The study was based on a questionnaire survey and the results were explored by descriptive statistic tools, tree classification analysis, factor analysis and cluster analysis. The results showed that the level of information is still low in general, with most people not manifesting an opinion. However, some aspects are relatively familiar to the participants (88.9% know that the ecological footprint of insects is smaller than other meats and 86.9% know that they efficiently convert or-ganic matter into protein). Factor and cluster analysis showed three classes: cluster 1—people not informed about the facts disclosed through the true statements and also not able to distinguish the false information; cluster 2—people not informed about the facts disclosed through the true statements but who were able to distinguish the false information; and cluster 3—people well in-formed about the facts disclosed through the true statements but who were marginally unable to distinguish the false information. It was also found that education, sex and professional area are the most relevant sociodemographic factors associated with the level of information, and the highest motivations to consume EIs are their contribution to preserve the environment and natu-ral resources followed by being a more sustainable option (for 64.7% and 53.4% of participants, respectively). Hence it was concluded that, although some work still needs to be done to better inform people about EIs, there is already some conscientiousness that they constitute a good and more sustainable alternative to other types of meat.
- Insights into the Consumption of Edible Flowers in Costa RicaPublication . Guiné, Raquel P. F.; Correia, Paula; Florença, Sofia De Guiné E; Moya, K.; Anjos, O.Edible flowers (EF) have been used since ancient times in some parts of the world, either for culinary purposes or as a traditional medicine. Their use in modern times is supported by high reputed chefs, who use and promote them in their gourmet preparations as highly valuable assets, having a great potential for decoration, flavour and aroma, besides their nutritional value. Moreover, they are very rich in some phenolic compounds, such as anthocyanins, responsible for the colours and which have a proven antioxidant capacity, so exerting a beneficial effect on the human body against oxidation and cellular stress. This study describes how the people in Costa Rica perceive edible flowers, if and how they consume them, how they buy them and how much they are acquainted with possible health risks associated with their consumption. It comprised a questionnaire survey undertaken on a sample of 130 participants from Costa Rica, carried out through the internet. The results obtained indicated that the great majority of the participants know what EF are, but they recognize that there is not enough information about this topic. Only about 30% of the participants are aware that consuming EF can bear some risks, which are associated with toxicity and possible presence of pesticides. About half of the participants have already consumed EF, particularly in salads, and for decoration and confection of dishes. The most consumed flowers are rose, camomile and pumpkin flower. The most relevant motivations to consume EF are their taste and aroma, as well as being a novelty and useful for decoration. These results allow us to understand some eating habits, knowledge and consciousness of people from Costa Rica towards EF.
- Study About the Consumption of Dairy products in Two CountriesPublication . Guiné, Raquel; Florença, S. G.; Carpes, S.; Anjos, O.The present chapter presents some results of a questionnaire survey undertaken on a sample of participants from Portugal and Brazil, which investigates the consumption habits of some classes of dairy products. This is a descriptive cross-sectional study made on a non-probabilistic convenience sample, consisting of 850 participants, 430 from Brazil and 420 from Portugal. The results obtained showed that in both countries the consumption of milk and milk products as well as cheeses, butters or yogurts was very low. Nearly half or more than half of the participants never consumed these dairy products, and those who consumes them did it only once or 2-3 times per week. Small differences were identified in the dairy consumption patterns in both countries, with slightly more Portuguese participants consuming milk, cheese, butter and yogurt as compared with Brazilians.
- Therapeutic Potential Applications for Bee PollenPublication . Florença, S. G.; Anjos, O.; Ferreira, Manuela; Campos, M. G.; Estevinho, L. M.; Correia, Paula; Costa, Cristina Amaro; Guiné, Raquel P. F.Since ancient times, bee pollen has emerged as a rich food product, which, besides being a source of energy, contains beneficial substances with recognized properties, both nutritionally and therapeutically. Recently, research about this natural product has allowed a more supported recognition of its health enhancement potential. The therapeutic properties of bee pollen are associated with the chemical composition, in particular vitamins, minerals, polysaccharides, and bioactive compounds, like phenolic acids and flavonoids. Due to the reasons highlighted, this review aims to synthesize some fundamental aspects of the relationship between the product's constituents and their respective bioactivity, in light of the most recent publications, which reveal the potential of bee pollen as a healthy product. Among them, citations of the most relevant benefits report the antioxidant, anti-inflammatory, antifungal, and antimicrobial bioactivities. Other potentialities, as the therapeutic use in drug discovery, include, for instance, the ability to modulate cancer development. Along the sections of this chapter these health effects will be presented and discussed.
