Factors determining organic consumers’ knowledge and practices with respect to wild plant foods: A countrywide study in Austria

Urban nature at the fingertips: Investigating wild food foraging to enable nature interactions of urban dwellers

Meaningful human-nature interactions can counteract the extinction of experience and positively influence people's nature relatedness, health and wellbeing. In this study, we explored urban wild food foraging to understand how best to enable human-nature interactions in cities by means of foraging. Using a structured questionnaire, a total of 458 residents of Vienna, Austria were surveyed. Sixty-four percent of visitors of public urban green spaces previously foraged for wild food species, whereas foraging frequencies were related to the targeted plant species and their life forms. People who foraged more frequently had greater nature relatedness, more childhood foraging experiences and lived on the outskirts of the city, but their socio-demographic backgrounds were heterogeneous. Social acceptance and lack of access to wild foods were perceived to be barriers. To promote nature relatedness through urban foraging, the legal framework, access to low-contamination foraging areas, availability of wild foods and social acceptance need to be improved.

Is "Wild" a Food Quality Attribute? Heavy Metal Content in Wild and Cultivated Sea Buckthorn and Consumers' Risk Perception

Globally, the consumption of herbal supplements is on an upward trend. As the food supplement industry thrives, so does the need for consumers’ awareness of health risks. This contribution is grounded on two assumptions. Firstly, not always “wild” is a food quality attribute, and secondly, the food chain is judged as a noteworthy route for human exposure to soil contamination. Sea buckthorn (SBT) was selected for investigation due to its versatility. In addition to its wide therapeutic uses, it is present in ecological rehabilitation which may raise concerns regarding its safety for human consumption as a consequence of the accumulation of contaminants in the plant. The study aims to discover if the objective contamination of SBT with toxic residues is congruent with people’s subjective evaluation of SBT consumption risk. A quantitative determination of heavy metals was performed by atomic absorption spectrometry. The metals abundance followed the sequence Fe > Cu > Zn > Mn > Cr > Ni > Pb > Cd. Quantitative data on consumers’ subjective risk evaluations were collected through an online survey on 408 Romanians. Binary logistic shows that the consumption of SBT is predicted by the perceived effect of SBT consumption on respondents’ health. The study confirms that the objective contamination of wild and cultivated SBT is in line with the perceived contamination risk. It is inferred that a joint effort of marketers, media, physicians, and pharmacists is needed to inform consumers about the risks and benefits of SBT consumption.

Design a Database of Italian Vascular Alimurgic Flora (AlimurgITA): Preliminary Results

Despite the large number of data published in Italy on WEPs, there is no database providing a complete knowledge framework. Hence the need to design a database of the Italian alimurgic flora: AlimurgITA. Only strictly alimurgic taxa were chosen, excluding casual alien and cultivated ones. The collected data come from an archive of 358 texts (books and scientific articles) from 1918 to date, chosen with appropriate criteria. For each taxon, the part of the plant used, the method of use, the chorotype, the biological form and the regional distribution in Italy were considered. The 1103 taxa of edible flora already entered in the database equal 13.09% of Italian flora. The most widespread family is that of the Asteraceae (20.22%); the most widely used taxa are Cichorium intybus and Borago officinalis. The not homogeneous regional distribution of WEPs (maximum in the south and minimum in the north) has been interpreted. Texts published reached its peak during the 2001–2010 decade. A database for Italian WEPs is important to have a synthesis and to represent the richness and complexity of this knowledge, also in light of its potential for cultural enhancement, as well as its applications for the agri-food system.

Perspectives on the trends, challenges and benefits of green, smart and organic (GSO) foods

Rapid rate of industrialization has turned our planet around in favor of fast foods, food fraud, food terrorism, food waste, food adulteration, food poisoning, food contamination and food injustice, paving the path for green, smart and organic products. Green foods are grown and harvested in the absence of any form of environmental pollution or harmful conditions. Smart foods are termed to be good for the consumers, farmers and the planet. Organic foods are regarded as “credence goods” because some of the attributes that consumers may consider are neither obvious nor easily verified. Therefore, these three terms are interconnected as they forge a substantive common denominator - healthfulness. The concepts of green, smart and organic (GSO) foods are herein recounted together with their interdependence and relationship to health and sustainability. The processes, policies and global trends of GSO foods were discussed, whilst not undermining the benefits and challenges associated with them.
