Abstract
Dry-aged beef provides superior qualities and a unique taste experience due to its exceptional sensory attributes, including tenderness, juiciness, and flavor, compared to traditional beef. Our study focused on the factors that impact consumers' intention to consume and willingness to pay for dry-aged beef. We implemented an extended version of the Theory of Planned Behavior (TPB) model that contains a measure of meat-eater identity to analyze the intention to consume and the willingness to pay a premium for dry-aged beef steak that has undergone 21-30 days of aging. An online survey was conducted with a stratified sample of Italian respondents (n = 944). The data were analyzed using partial least squares structural equation modeling (PLS-SEM). The TPB's effectiveness was enhanced by adding the meat-eater identity construct to the model. Specifically, it was found that the participants' meat-eater identity significantly influenced their intention to consume. The results also revealed that the most critical impact of identity comes from the mediated influence of attitudes, subjective norms, and perceived behavioral control. Finally, the intention to consume strongly influenced the willingness to pay for a dry-aged beef steak.

Abstract
Enhancing the willingness to eat edible offal can be a valuable strategy to mitigate the greenhouse gas (GHG) emissions related to growing meat production and to provide food with high protein content to a growing global population. Although some edible offal is considered delicacies, we hardly find such foods in Western countries' everyday diet, and their human consumption has decreased during the last decades. This study analyses the consumer purchase intention of BEEF edible offal using an extended version of the Theory of Planned Behaviour (TPB), where food neophobia and food disgust sensitivity play an essential role in determining consumers' willingness to eat beef edible offal. An online survey was conducted among a sample of Italian adult regular meat eaters (n = 720), stratified by age, gender, education and residence. The results showed a direct negative impact of food neophobia on the intention to consume offal. Further, we were able to quantify a negative indirect impact of food neophobia on intention through the mediation of food disgust sensitivity and attitudes, subjective norms and perceived behavioural control, which all exert an essential role in determining the willingness to consume beef edible offal. We found that the mediated impact of food neophobia on the intention to consume beef offal is much higher than the direct impact. In conclusion, recommendations and implications, such as promoting cooking shows with celebrity chefs, new products or new packaging of edible offal, were developed based on the results to increase edible beef consumption.

Abstract
The growing demand for livestock products is associated with an increase in environmental, economic, and ethical issues. New alternative sources of protein such as edible insects have recently been developed to tackle these issues with fewer drawbacks. However, several challenges are associated with insect-based food, mainly regarding consumer acceptance and commercialization. In this systematic review, we explored these challenges by reviewing 85 papers from 2010 to 2020, which were selected following the PRISMA methodology. Additionally, we applied the SPIDER (Sample, Phenomenon of Interest, Design, Evaluation, and Research type) tool for developing the inclusion criteria. Our analysis adds new knowledge to previous systematic reviews on this topic. It reveals both a comprehensive framework of factors influencing consumers' acceptance of insects as food and aspects of the marketing mix of these products. Disgust, food neophobia, familiarity, visibility of insects, and taste appear to be the most significant factors that can prevent consumers from consuming insects as food. The motivations for acceptance are found to be familiarity and exposure. The results of this review provide insights for policymakers and stakeholders who wish to develop marketing strategies that can increase consumer acceptance of insects as food.

Abstract
Natural fluoride contamination of drinking water is a serious issue that affects several countries of the world. Its negative health impact is well documented in the East African Rift Valley, where water consumption with fluoride ( F - ) concentration greater than 1.5 mg/L can cause fluorosis to people. Within the framework of the European Union (EU) Horizon 2020 FLOWERED project, we first designed an effective defluoridation device based on innovative application of octacalcium phosphate (OCP) and then explored its acceptance within rural communities. The prototype (FLOWERED Defluoridator Device [FDD]) essentially is composed of a 20-L tank and a recirculating pump that guarantees the interaction between water and OCP. The device is powered by a car battery for a fixed pumping working time using a fixed amount of OCP for every defluoridation cycle. The results of tests performed in the rural areas of Tanzania show that a standardized use of the prototype can lower the dissolved F - from an initial concentration of 21 mg/L to below the World Health Organization (WHO) drinkable limit of 1.5 mg/L in 2 h without secondary negative effects on water quality. The approximate cost of this device is around US$220, whereas that of OCP is about $0.03/L of treated water. As with any device, acceptance requires a behavioral change on behalf of rural communities that needed to be investigated. To this end, we piloted a survey to explore how psychological and socioeconomic factors influence the consumption of fluoride-free water. Results show that the adoption of FDD and OCP is more appealing to members of the rural communities who are willing to pay more and have a high consumption of water. Moreover, we suggest that given the low level of knowledge about fluorosis diseases, the government should introduce educational programs to make rural communities aware of the negative health consequences.

Abstract
The relationship between naturally fluoridated groundwater and dental fluorosis has received large attention from researchers around the world. Despite recognition that several factors influence this relationship, there is a lack of systematic studies analyzing the heterogeneity of these results. To fill such a gap, this study performs a systematic review and meta-analysis to understand which factors influence this relationship and how. Selected studies were sampled between 2007 and 2017 from Web of Science, PubMed, Google Scholar and Scopus using keywords and Boolean operators. Results of the systematic review show that dental fluorosis affects individuals of all ages, with the highest prevalence below 11, while the impact of other factors (gender, environmental conditions, diet and dental caries) was inconclusive. Meta-regression analysis, based on information collected through systematic review, indicates that both fluoride in drinking water and temperature influence dental fluorosis significantly and that these studies might be affected by publication bias. Findings show that fluoride negatively affects people's health in less developed countries. The conclusions discuss policy tools and technological innovations that could reduce fluoride levels below that of the World Health Organization (WHO) (<1.5 mg/L).

Abstract
The aim of this paper is to investigate consumers’ preferences and willingness to pay (WTP) for functional mozzarella cheese whose health benefits (reduced fat and enrichment in omega-3) are communicated by using nutrition claims (article 8) and health claims (articles 13 and 14) of the EU Regulation 1924/2006. In order to achieve the stated objective a choice survey was developed and administered to a sample of Italian respondents. The product attributes and attribute levels included in the choice experiment were obtained from in-depth interviews conducted with stakeholders working on the development of this new product in the Italian region of Puglia. Results show that many participants were not aware of functional food. Marketing segmentation performed via latent class analysis indicates that the development of this hypothetical product should be based on the addition of naturally enriched omega-3. In terms of health communication under Regulation 1924/2006, heterogeneity of preferences of the nine identified segments reveals that respondents have a clear preference for products from the Puglia region, for the combined nutrition claim over single nutrition claims and for the reduction of disease health claim (article 14) over the health claim (article 13). In monetary terms, willingness to pay for health claims is higher than nutrition claims.

Abstract
OBJECTIVE To investigate the sociodemographic determinants of diet quality of the elderly in four EU countries. DESIGN Cross-sectional study. For each country, a regression was performed of a multidimensional index of dietary quality v. sociodemographic variables. SETTING In Finland, Finnish Household Budget Survey (1998 and 2006); in Sweden, SNAC-K (2001-2004); in the UK, Expenditure & Food Survey (2006-07); in Italy, Multi-purpose Survey of Daily Life (2009). SUBJECTS One- and two-person households of over-50s (Finland, n 2994; UK, n 4749); over-50 s living alone or in two-person households (Italy, n 7564); over-60 s (Sweden, n 2023). RESULTS Diet quality among the EU elderly is both low on average and heterogeneous across individuals. The regression models explained a small but significant part of the observed heterogeneity in diet quality. Resource availability was associated with diet quality either negatively (Finland and UK) or in a non-linear or non-statistically significant manner (Italy and Sweden), as was the preference for food parameter. Education, not living alone and female gender were characteristics positively associated with diet quality with consistency across the four countries, unlike socio-professional status, age and seasonality. Regional differences within countries persisted even after controlling for the other sociodemographic variables. CONCLUSIONS Poor dietary choices among the EU elderly were not caused by insufficient resources and informational measures could be successful in promoting healthy eating for healthy ageing. On the other hand, food habits appeared largely set in the latter part of life, with age and retirement having little influence on the healthiness of dietary choices.
