Adolescents have increasing influence over their food choices, informed by their developing personal knowledge and values, affecting long-term dietary behaviors into adulthood. The recent literature regarding adolescents' (1) perceptions of environmentally sustainable diets and (2) interventions to support adolescents to eat sustainably was reviewed in this study. We reviewed published literature that focused on adolescent participants and their perceptions of, or interventions to support, sustainable dietary habits. Five electronic databases were searched to include studies published since 2012 that met the inclusion criteria, including reporting of participants aged between 11 and 18 years, reporting on adolescents' perceptions of sustainable diets or interventions implemented to improve the sustainability of adolescents' diets, and framed in the context of sustainability. Data were extracted, including study and participant characteristics, methodology, and results in relation to each of the 2 research focus areas. Twenty-eight articles were included in the review. Findings suggest that adolescents' understanding of what constitutes sustainable eating is poor. Adolescents who had previously received education regarding sustainable diets valued nature and health, or were from a rural or indigenous community, were more likely to value environmentally sustainable-food choices. Interventions which target adolescents' understanding of and aspiration to make sustainable-food choices appears to improve their attitudes toward sustainable food, whereas interventions to increase the availability of sustainable foods improved the environmental sustainability of adolescents' dietary intake. Multicomponent, tailored, and community-based interventions were most effective; however, the long-term effect of these interventions remains unclear. More research is needed in low- and middle-income countries, with consideration of adolescents' level of autonomy in food choice in local food environments and the long-term effectiveness of interventions.

This delicate balance of microbiota plays an important role in health and disease and is highly influenced by lifestyle factors and the surrounding environment. As further research emerges, understanding the full potential of the gut microbiome and the impact of using nutraceuticals to positively influence its function may open the door to greater therapeutic outcomes in the treatment and prevention of disease. Curcumin, a bioactive compound derived from the turmeric rhizome, has been studied in depth for its influence on human health as a potent anti-inflammatory and antioxidant properties. However, the therapeutic activity of curcumin is limited by its low oral bioavailability. While most available research has primarily focused on the curcuminoid compounds of turmeric, the non-curcuminoid compounds hold promise to offer therapeutic benefits while synergistically enhancing the bioavailability of curcumin and supporting the gut microbiome. This review summarizes current knowledge of the relationship between the gut and the various systems within the body, and how dysbiosis, or disruption in the gut microbial balance, leads to inflammation and increased risk of chronic disease.

For this, a scoping review was conducted according to recommendations from the Joanna Briggs Institute. Systematic searches were performed in 6 databases using terms related to industrial trans fats, identification of possible substitutes, and trans fats exemption. The search retrieved 5072 articles.

A total of 87 different raw materials were cited as trans fats substitutes in the selected studies, with palm stearin being the most frequent. The processing methods were categorized in 8 groups, with interesterification being the most cited (46% of studies). Food items belonging to 15 food groups were found to contain trans fats substitutes, mainly margarine, shortenings, and spreads.

Appetite self-regulation, along with other domains of self-regulation, develops across childhood and contributes to energy intake and balance, diet quality, weight, and therefore long-term health outcomes. There have been efforts to conceptualize and measure components of ASR and associated processes/mechanisms, but, at present, there is no unifying conceptualization of ASR in childhood. A search of key databases supplemented by snowballing was undertaken for definitions/conceptions and theoretical models of ASR with a focus on children. An interpretive synthesis approach was used to identify themes from the definitions and models. The themes formed the basis of the proposed unifying generalized model of ASR in childhood, which is the main contribution of the article. At the center of the model is bottom-up reactivity to food, food cues and hunger, satiation and satiety signals, together with top-down regulatory control. An additional contribution is the proposed 5 interacting and overlapping domains (biological, hedonics, cognitive, behavioral, and traits) that function in and influence both bottom-up reactivity and top-down regulation. The domains also contribute to ASR outcomes of enactment and competence. External contextual and intrapersonal factors are conceived as impacting the domains and the bottom-up, top-down processes. The relevance of the model for explanations of ASR phenomena in childhood and children's food choice and diet quality, as well as its implications for research directions and approaches to preventive intervention, including food parenting practices, are discussed. The model provides a framework for researchers and practitioners to support and interpret children's problems and competence in self-directing food choices, energy intake, and nutrition.</p>","PeriodicalId":19469,"journal":{"name":"Nutrition reviews","volume":" ","pages":""},"PeriodicalIF":5.9,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143023687","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
