Abstract
Concerns about the numerous health problems associated with unhealthy snacks prompted recommendations to steer individuals toward healthier eating habits. One such recommendation advises limiting unhealthy snacks and replacing them with more fruits and vegetables with significant health benefits. This study investigates US consumers' perceptions and preferences for healthy (vegetable-based) snacks/beverages. An online survey was designed to estimate consumer perception and willingness-to-pay (WTP) for vegetable-based crackers, spreads, and beverages. A sampling company sent the survey to its national consumer panels in 2020, resulting in a sample of 402 US consumers. Eligible participants were adults, primary grocery shoppers who consumed crackers, spreads, and beverages. Consumer WTP for healthy snacks/beverages, the dependent variable, was elicited using a payment card method. Independent variables include personality traits (Innovativeness and Extraversion) and the important factors affecting healthy snack purchases, health consciousness, and demographic variables. Results show that consumers' preferences for healthy snacking vary by product, even when the products have similar health benefits. Significant positive associations exist between WTP for healthy snacks/beverages and personality traits, health consciousness, and some demographics. This study provides critical insights to policymakers and informs marketing campaigns to promote healthy snacking in the US more effectively.

[PMID: 37238832 DOI: 10.3390/foods12102014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2023] [Revised: 05/12/2023] [Accepted: 05/15/2023] [Indexed: 05/28/2023] Open
Abstract
In recent years, consumers have shown considerable attention to functional foods that can provide various benefits. At the same time, the awareness of the problem of waste generation from the agri-food supply chains has increased; thus, scholars and practitioners are devoting great attention to sustainable food waste management. Within the wine processing, the production phase generates by-products such as marc, grape seeds, stems, and wine lees. In most cases, these by-products are treated as waste rather than as a resource, creating environmental, economic, and social impacts related to their disposal. By contrast, the reuse of oenological by-products in food production can have several health benefits, since they are rich in functional molecules such as fibres, polyphenols, and vitamin E, and can also trigger a circular economy model. The aim of this research is to investigate the acceptance of consumers towards bread enriched with oenological by-products through the application of k-means clustering, providing insights on the characterisation of groups of consumers based on their specific features and declared attitudes. The results showed three different consumers' clusters, highlighting that the acceptance of this enriched bread is not influenced by the consumers' socio-economic features, but it is related to consumers' sensitivity. Therefore, target strategies should be put in place to inform consumers about the benefits associated with the consumption of bread enriched with oenological by-products.

Abstract
Rice and cereal consumption has become a concern for consumers due to usually high glycaemic indexes (GI), which is a critical issue for a balanced and healthy diet. Therefore, the development of new products with low GI is an important target of the industry, particularly in countries with high consumption. This study assesses consumers’ perceptions about “rice” and “rice with low GI” and evaluates the effect of consumers’ rice consumption profiles through the application of a free word association technique in a structured self-administered electronic questionnaire with 256 Portuguese consumers (the European market with the highest per capita consumption of rice by far). The frequency of rice consumption was evaluated, and the consumption profile was determined through a hierarchical cluster analysis, with 9% identified as daily consumers. The response words were categorized by the triangulation technique, and the association between the word categories and dimensions, sociodemographic characteristics, and consumption profile were determined. Respondents most frequently associated “rice” with rice dishes, its sensory attributes, and nutrition, highlighting the satisfaction of nutritional and hedonic needs. Consumers revealed positive expectations in relation to the functionality of “rice with low GI”. The consumers’ rice consumption profiles, sex, age, and educational levels influenced their perception towards “rice“ and “rice with low GI”. This study provides important insights for the industry to develop a consumer-oriented, low GI rice product.

Abstract
BACKGROUND: The healthy diet is important to maintain immunity against infection. This study aimed to assess and compare the consumption of functional foods, some antioxidants, and dietary inflammatory index between Iranian COVID-19 patients and healthy persons. METHODS: This case-control study was conducted between 1000 (500 cases and 500 controls) adults aged 18–65years in Iran, that were sampling based on the snowball method and their information was collected electronically. The dietary intake was assessed using the Food Frequency Questionnaire (FFQ). RESULTS: There was a significant difference (p = 0.044) in vitamin D consumption between healthy people and COVID-19 patients. Vitamin E intake in healthy participants was significantly (p = 0.041) more than COVID-19 patients. There was a significant difference in Zinc (p = 0.011), selenium (p = 0.021), and vitamin C (p = 0.023) between healthy persons and COVID-19 patients. Healthy participants’ consumption of onion (56.5±7.82 g/day), garlic (4.32±0.01 g/day) and oat (6.32±0.71 g/day) was significantly (p≤0.05) more than COVID-19 patients. With the increase of each unit in the score of the dietary inflammatory index, the risk of COVID-19 incidence increased 1.63 times (OR = 1.63 95% CI: 1.54–1.72). There was an inverse association between the consumption of antioxidants and functional foods with the risk of COVID-19 incidence in the study population (p≤0.05). CONCLUSION: Healthy people consumption of antioxidants and functional foods was more than COVID-19 patients and there was a significant inverse association between the risk of COVID- 19 incidence with the consumption of functional foods and antioxidants. Increasing the dietary inflammatory index score increased the risk of COVID- 19 incidence. There is a need for further clinical trials to confirm the effect of consuming functional foods and antioxidants on the prevention or treatment of COVID-19.

Abstract
Chronic diseases (e.g., heart disease, cancer, diabetes) are of major public concern. Such chronic diseases are often caused by a dietary pattern characterized as relatively high in fat, refined sugar, salt, and cholesterol. Societal interest in consuming healthy foods and the demand for healthy food products have increased significantly. As a result, functional foods have gained significant research attention in the food health and technology innovations field. To date, many studies have investigated the factors that may predict consumer acceptance of functional foods, and a wide range of influential factors have been reported. However, studies conducted in different contexts pose challenges to gaining a clear understanding of the factors influencing consumer acceptance. Therefore, the purpose of our scoping review was to synthesize the possible determinants of consumer acceptance toward functional foods and provide a resource that describes global trends regarding consumers' functional foods behavior. We identified 75 articles published with varying populations around the globe that empirically investigated consumers' acceptance of functional foods. We identified and categorized a wide range of determinants related to consumer acceptance of different types of functional foods. The five categories of determinants were product characteristics, socio-demographic characteristics, psychological characteristics, behavioral characteristics, and physical characteristics. Each of the determinants were more fully described by sub-determinants in our scoping review. These determinants should be considered and used by leaders and scientists in product development to aid decision making and, ultimately, the successful launch of novel functional foods.

Abstract
This study aimed at assessing the impacts of the fear of COVID-19 on consumer buying behavior toward dietary supplements. This investigation was a cross-sectional study in which literate adults regardless of gender over the age of 20 were recruited from three pharmacies in three different districts of Wuhan City, China. A total of 598 questionnaires were analyzed after excluding 10 with incomplete information. The current study demonstrated that attitudes, subjective norms, and perceived behavioral control had a positive impact on the intention of purchasing dietary supplements. Fear of COVID-19 was related to an enhanced purchase intention toward dietary supplements. Attitudes, subjective norms, and perceived behavioral control were significant factors that mediated the association between the fear of COVID-19 and the purchase intention of dietary supplements. This study helps provide practical advice for stakeholders in the pharmaceutical and healthcare industries to tailor appropriate strategies for improving product promotion or healthcare-related interventions.

Abstract
Given the growing market for health-enhancing or functional foods in Iran, the consumption rate is low. Identifying and understanding the causes is key for future decisions and interventions in the market. So, the present study was designed to provide this knowledge in Iran. The study was conducted in Tehran, the capital of Iran, between May and September 2014. In total, 105 people participated in this qualitative research, including 40 production/supply/health authority stakeholders and 65 consumer stakeholders (44 housewives and 21 employed women). The sampling strategy was the purposive method with maximum diversity, and snowball sampling was used to identify key stakeholders. The social marketing framework was used for analyzing the participants' views and experiences. To collect data, semi-structured focus group discussions and in-depth interviews were conducted. Data collection and content analysis were performed simultaneously, using MAXQDA® software. Categorization of the findings based on social marketing mix showed that the most important barriers to the consumption of functional dairy products were undesirable sensory and non-sensory characteristics, lack of physical and economic access to the product, the existence of product competitors in the market and inappropriate promotion strategies. Furthermore, personal barriers identified as a new dimension and included lack of knowledge about the product and its benefits, a negative attitude toward the product and personal taste and preference. Understanding these barriers might contribute to design and implement effective and appropriate interventions to increase the consumption of these products among consumers.

Abstract
Upcycled ingredients are one of the most significant current trends in the food industry aimed to tackle the challenge of solid food loss reduction. This study investigates the potential market among Millennial consumers for products enriched with upcycled ingredients in Italy. We surveyed a sample of 317 Italian Millennial consumers, using a web-based survey. 62% of respondents declared to be informed about the existence of food made from upcycled ingredients and 53% declared to be willing to buy this novel food. Also, 69% of respondents think that food enriched with upcycled ingredients can bring environmental benefits, while only 40% believe that it can bring health benefits. Using a logit model to analyse consumer preferences, we found that food neophobia and food technology neophobia negatively impact on the likelihood of being willing to buy food produced with upcycled ingredients. Also, consumers who give high importance to food certification are less likely to be willing to buy upcycled foods. Contrariwise, reading labels and believing that upcycled foods are healthier or more environmentally friendly positively impacts on the willingness of Millennial consumers to buy these foods. Results for the sample analysed eventually suggest that giving right information to consumers about the environmental and health characteristics of the products, through clear labelling, could increase their market uptake thus helping to reduce food loss and contributing to reaching circular economy objectives in the agricultural sector.

Abstract
The proportion of older adults in the population is significantly growing in the EU, therefore, wellbeing of the older population has become a social challenge. Functional foodstuffs are food products with nutritional composition that may reduce the risk of diet-related diseases or enhance physiological functions. Therefore, they could play an important role in prevention and mitigation of health-related problems, and in promotion of healthy ageing. The aim of this study is to present the impact of age on consumer preferences about functionality of foods, covering attitude aspects, nutrition claims, possible carriers, some particular health problems and expectations about sustainable production. The results are based on a representative quantitative survey. Findings highlight statistically significant (p < 0.05) differences in preferences of older adults compared to other age segments. They generally accept functional foods, especially when functionality is attached to increased vitamin, protein, and fiber content. Older adults also prefer products with lower salt and sugar content, which were less relevant for other age groups. Products of fruit and vegetable origin are distinguished as carriers of functional traits. Compared to other segments, older adults accept products of animal origin (especially milk products) and even breakfast products on a higher level. The paper provides details about particular health issues that could be addressed by functional foods based on actual consumer concerns.

Abstract
The paper investigated whether information about the health benefit produced by lycopene could influence consumers’ willingness to pay (WTP) for canned crushed tomatoes enriched with lycopene. An additional aim was to determine whether the main socio-demographic variables, such as sex, age, income and selected attitudinal factors, affect WTP. To this end, a non-hypothetical experimental auction was carried on with five repeated rounds. Results show a relevant impact of information on WTP in the case of lycopene-enriched products, whereas no difference in bids emerges for the conventional product, either on average or at the quantiles. Previous knowledge seems to have a modest influence upon WTP, but it shows a significant interaction with the information shock provided during the experiment, so that the effect of the latter is more pronounced when previous knowledge is low. In addition, age, sex, food technology neophobia, trust in science and implicit attitudes towards food technology significantly affect participants’ WTP.
