Abstract
In this qualitative study, we explored Portuguese adolescents' perceptions of diet, sustainability, and health through six focus group discussions (FGDs). Fifty-five adolescents (10-18 years) participated. FGDs focused on sustainability in food choices and its health impact, with our primary interest in their perceptions. Results showed a limited comprehension of "sustainable/sustainability," especially among younger participants. Those aware of sustainability recognized its diverse aspects, including health, economic, and ecological domains. Some adolescents recognized the link between health and sustainability in their diets, emphasizing the need for food literacy. These findings emphasize the importance of public health and sustainable policies among Portuguese adolescents.

Abstract
Food labeling is increasingly expanding and adding more information to the food package. There is strong evidence about nutrition labeling effectiveness in driving food choice, especially if displayed in the front of package (FoP). Despite the growing attention to nutrition and sustainable diets, few countries have implemented sustainable labels or eco-labels that could address economic, social and/or environmental concerns. Implementing new techniques of eco-labeling emerges as a consumer-focused solution. However, evidence of the effectiveness of eco-labeling in driving consumers' choices is heterogeneous and not univocal. Thus, this review aims to summarize the evidence about the effectiveness of FoP eco-labeling in driving food choice and provide a reference framework of the eco-labeling initiatives relative to food package labeling. This narrative review addresses both the potential benefits as well as the main concerns that arise from the use of eco-labels. Although eco-labeling seems to provide a series of sustainability benefits for producers and consumers, the implementation of such policies should take into consideration potential trade-offs and inter-sectorial coordination to obtain bigger impacts, assuming that a policy itself cannot transform the whole food system. Eco-labeling could be encouraged and implemented within a set of policies shaping sustainable food systems.

Awareness, use and understanding of nutrition labels among children and youth from six countries: findings from the 2019 - 2020 International Food Policy Study. Int J Behav Nutr Phys Act 2023; 20:55. [PMID: 37143053 PMCID: PMC10157591 DOI: 10.1186/s12966-023-01455-9] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2022] [Accepted: 04/21/2023] [Indexed: 05/06/2023] Open
Abstract
BACKGROUND Nutrition facts tables (NFTs) on pre-packaged foods are widely used but poorly understood by consumers. Several countries have implemented front-of-package labels (FOPLs) that provide simpler, easier to use nutrition information. In October 2020, Mexico revised its FOPL regulations to replace industry-based Guideline Daily Amount (GDA) FOPLs with 'Warning' FOPLs, which display stop signs on foods high in nutrients of concern, such as sugar and sodium. This study examined self-reported awareness, use, and understanding of NFTs and FOPLs among young people in six countries with different FOPLs, with an additional focus on changes before and after implementation of Mexico's FOPL warning policy. METHODS A 'natural experiment' was conducted using 'pre-post' national surveys in Mexico and five separate comparison countries: countries with no FOPL policy (Canada and the US), countries with voluntary FOPL policies (Traffic Lights in the UK and Health Star Ratings in Australia), and one country (Chile) with mandatory FOPL 'warnings' (like Mexico). Population-based surveys were conducted with 10 to 17-year-olds in 2019 (n = 10,823) and in 2020 (n = 11,713). Logistic regressions examined within- and between-countries changes in self-reported awareness, use, and understanding of NFTs and FOPLs. RESULTS Across countries, half to three quarters of respondents reported seeing NFTs 'often' or 'all the time', approximately one quarter reported using NFTs when deciding what to eat or buy, and one third reported NFTs were 'easy to understand', with few changes between 2019 and 2020. In 2020, awareness, use and self-reported understanding of the Warning FOPLs in Mexico were higher than for NFTs in all countries, and compared with GDA FOPLs in Mexico (p < .001). Mandated Warning FOPLs in Mexico and Chile had substantially higher levels of awareness, use, and understanding than the voluntary Traffic Lights in the UK and Health Star Ratings in Australia (p < .001 for all). CONCLUSIONS Mandated easy-to-understand FOPLs are associated with substantially greater levels of self-reported awareness, use and understanding at the population-level compared to NFT and GDA-based labeling systems.

Abstract
Introduction Unhealthy food choices increase the risk of obesity and its co-morbidities. Nutrition labels are a public health policy that aims to drive individuals toward healthier food choices. Chile has been an example of this policy, where mandatory nutrient warning labels (NWL) identify processed foods high in calories and critical nutrients. Eating contexts influence individual food choices, but whether eating contexts also influence how NWL alter the decision process and selection during food choice is unknown. Methods In an online mouse-tracking study, participants prompted to health, typical, or unrestricted eating contexts were instructed to choose between pairs of foods in the presence or absence of NWL. Conflict during choices was analyzed using mouse paths and reaction times. Results NWL increased conflict during unhealthy food choices and reduced conflict during healthy choices in all contexts. However, the probability that NWL reversed an unhealthy choice was 80% in a healthy, 37% in a typical, and 19% in an unrestricted context. A drift-diffusion model analysis showed the effects of NWL on choice were associated with an increased bias toward healthier foods in the healthy and typical but not in the unrestricted context. Discussion These data suggest that the efficacy of NWL to drive healthy food choices increases in a healthy eating context, whereas NWL are less effective in typical or unrestricted eating contexts.

Eating in Season—A Lever of Sustainability? An Interview Study on the Social Perception of Seasonal Consumption. SUSTAINABILITY 2022. [DOI: 10.3390/su14095379] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 01/27/2023]
Abstract
Seasonality is a lever of sustainability. However, very little is known about the social perceptions of “in season” food consumption. We aimed to explore different French social groups’ perceptions of seasonality, “in season” food choices, and their respective advantages or disadvantages. We interviewed 73 individuals (general population = 32, clients of short supply chains = 28, Etiquettable (a sustainability app) users = 13). In-depth, semi-structured interviews using open-ended questions were conducted. Content and thematic, textual, and quantitative analyses were performed. We found four clusters of interviewees who differed in social backgrounds and motivations for eating “in season.” A social divide between individuals for whom “eating seasonally” was a priority (upper strata), and those who “eat unseasonally” (lower strata) was highlighted. An analysis of motivations showed a contrast between individuals who were familiar with seasonal food rhythms and aimed to support the local economy and the older generation for whom seasonal products gave better value for money. The implications of public action on sustainable consumption are discussed with respect to the knowledge of seasonality, targeted segments of the population, and a combination of arguments to encourage seasonal consumption.
