This is a complex task requiring integration of environmental, cultural, psychological and biological contributions. Work in the area of precision nutrition is an effort to translate science into practice. A research roadmap developed through an National Institutes of Health (NIH) conference identified many of the inputs that require quantification. Better characterization of ingestive behaviors is one key area. The aim of this narrative review is to summarize current understanding of the influences of age, sex, Body Mass Index (BMI), ethnicity and genetics on ingestive behaviors, including culture, sensory function, appetite, dietary intake, the gut-brain axis and microbiome. To do so, the extant literature was accessed through search engines relevant to the various topics covered. Outcomes assessed varied topically. In addition to compiling evidence on the nature and magnitude of these relationships, this review highlights the degree of individual variability in attributes or responses to an intervention. More broadly, it: a) documents that cause and effect relationships are difficult to establish as most are dynamic and interactive; b) there are inherent and learned contributions to both behavior and biology that will require different considerations and offer different opportunities for manipulation; c) a focus on intuitive approaches may not be as successful as desired; d) that external influences can, and often do, override internal influences of biology; and e) there are multiple ways to construct healthful diets. At the same time, it is vital that improved methods to characterize the multiple relevant inputs to ingestive behavior be developed. It is hoped the evidence compiled here will inform efforts to develop precision nutrition guidance.</p>","PeriodicalId":72101,"journal":{"name":"Advances in nutrition (Bethesda, Md.)","volume":" ","pages":"100531"},"PeriodicalIF":9.2,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145226376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

HFVPs can complement policies aimed at reducing unhealthy food consumption, contributing to improved food security, dietary outcomes and reducing nutritional disparities. Understanding the structural factors that make these programs acceptable and effective in improving dietary patterns is essential for designing impactful HFVPs. However, updated evidence on these components is limited. This narrative review focuses on incentive programs that provide voucher benefits for healthy foods, synthesizing global evidence on program structure components (i.e., participant eligibility and enrollment, benefit delivery and timing, eligible products, benefit value, program duration, retail venues, and inclusion of nutrition education) that may influence program impact. It also summarizes diet and nutrition-related outcomes by country's income level, when possible. Key determinants of program acceptability included positive interactions with program and retail staff, available multilingual information, electronic benefits over physical ones, a variety of eligible healthy foods, and including local markets as participating venues. Additionally, offering remote enrollment options, using mail delivery or electronic benefits to avoid transportation costs, adjusting benefits for inflation and household size, allowing redemption in various retail venues, and coupling benefits with engaging nutrition education activities were factors influencing program effectiveness. Most evidence indicates that HFVPs increase the purchase and consumption of healthy foods, improve food security, and enhance nutrition knowledge. However, mixed results were found regarding diet quality indicators, physical health outcomes, and mental health. Factors such as insufficient benefit size, inflation and rising food prices, and short intervention lengths contributed to null results. Our findings underscore the potential of HFVPs to improve diets and reduce nutritional disparities; however, addressing identified barriers during program design and implementation is essential to ensure these programs achieve their goals. STATEMENT OF SIGNIFICANCE: This review provides a comprehensive synthesis of the global evidence on healthy food voucher programs, highlighting structural components that significantly influence their acceptability and effectiveness across diverse populations. By emphasizing the importance of tailored program design and examining key factors that influence success, it provides a valuable foundation for future policy development and evaluation.</p>","PeriodicalId":72101,"journal":{"name":"Advances in nutrition (Bethesda, Md.)","volume":" ","pages":"100530"},"PeriodicalIF":9.2,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145226420","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Numerous observational epidemiology studies have evaluated the effect of NSSs on cancer risk, sometimes focusing on a specific NSS or a specific cancer, other times focusing on all NSSs and all cancers. We conducted a systematic review of epidemiology studies of NSS intake (of all types in aggregate and individually) and the risks of all types of cancer published through Fall 2024 (pre-registered with Open Science Framework [https://osf.io/gc8v6]). We considered how major study quality concerns might have impacted the interpretation of individual study results, as well as the evidence as a whole. We identified 90 studies of acesulfame potassium (ace-K), aspartame, cyclamate, saccharin, sucralose, or non-specific NSSs in aggregate (e.g., diet sodas, artificially sweetened beverages [ASBs]), and 17 specific types of cancer. We found no consistent associations between any NSS or NSSs in aggregate and any cancer overall, and no evidence for dose-response. NSS intake information was always self-reported, rendering exposure misclassification an ongoing challenge in all studies, and recall bias remains a significant possibility in all case-control studies. Many studies also did not fully account for potential confounders. Experimental animal and mechanistic evidence for NSSs does not support human-relevant carcinogenicity or any biologically plausible mechanisms by which NSSs could cause genotoxicity or cancer in humans.

This review systematically synthesized the literature that examined the longitudinal associations between changes in dietary intake (i.e., trajectories) from early life and health outcomes. Electronic searches were conducted in PubMed, Embase, and ScienceDirect to gather longitudinal cohort studies that investigated dietary intake trajectories from infancy, childhood or adolescence (with first dietary assessment before age 18 years) and any health outcomes published from inception to September 2024 (CRD42024512716). Of sixteen included studies, 14 reported significant associations between dietary intake trajectories (intakes of macronutrients, food groups, diet quality or dietary patterns) in childhood or from childhood to adolescence/early adulthood and dental, obesity, cardiometabolic, neurocognitive, liver or gut health outcomes from age 2 years up to age 41 years. Most studies were of high (n=2) or acceptable (n=12) quality. A high or increasing sugar intake trajectory during infancy was linked to an increased risk of dental caries in early childhood, while a healthy dietary pattern trajectory was associated with lower risk. Trajectories of poor diet quality, red meat dietary pattern, high discretionary food intake from infancy/early childhood were associated with adiposity and adverse cardiometabolic outcomes at adolescence and adulthood. Significant associations were also found between trajectories of dietary patterns or macronutrient intakes (e.g., protein, carbohydrates, dietary fibre) from infancy and neurocognitive outcomes in childhood. High energy intake trajectory from early childhood to adolescence and carbohydrate intake from infancy to early adulthood were associated with poor liver health outcomes and gut microbiota composition in adulthood, respectively. Dietary intake trajectories established from infancy or early childhood were associated with various health outcomes. Dietary interventions should be initiated from infancy or early childhood for early health promotion.</p>","PeriodicalId":72101,"journal":{"name":"Advances in nutrition (Bethesda, Md.)","volume":" ","pages":"100528"},"PeriodicalIF":9.2,"publicationDate":"2025-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145208558","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its synthesis is dependent on the availability of its dietary precursor, the essential amino acid tryptophan (Trp), with impact on biochemical pathways that may be modulated by other nutrients. We conducted a literature review search to comprehensively examine the nutritional influences on the serotonergic system. Relevant original research, systematic reviews, meta-analyses, and clinical trial reports were retrieved from PubMed, Scopus, and Google Scholar, with additional articles identified from reference lists of published review papers. Key nutritional determinants of serotonergic function include macronutrients that influence tryptophan-to-large-neutral-amino-acid (Trp/LNAA) ratio, a regulator of brain Trp availability, and micronutrients such as B-vitamins, vitamin D, iron and magnesium that serve as essential cofactors in serotonin synthesis and metabolism. Emerging evidence also highlights the role of the gut microbiota, shaped by dietary components, prebiotics and probiotics, in modulating serotonergic function across both central and peripheral systems. Nutritional factors that affect serotonin have been increasingly linked to conditions such as depression, anxiety, sleep disturbances, disordered eating, obesity, and irritable bowel syndrome. Altogether, this review emphasizes the profound impact of nutrition on serotonergic regulation, and advocates for targeted dietary approaches as promising catalysts for optimizing human health. Key research gaps and future directions are outlined to help advance the translation of current evidence into precise nutritional guidelines and clinical applications, with the complexity of serotonin pathways as an important consideration.

We conducted a scoping review to identify gaps in existing assessment tools for food acquisition, preparation, and household consumption practices in South Asia, where diets are rapidly changing. We undertook systematic keyword searches of three databases (PubMed, Scopus, and Web of Science Core Collection) to identify studies assessing food acquisition, food preparation, and household consumption practices in Afghanistan, Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, and Sri Lanka, published in English between 2000 and April 2025. Two reviewers independently screened titles, abstracts, and full texts, and extracted data on study characteristics and the assessment tools used to examine the food choice behaviors. Of 13,160 unique articles identified, 50 were included for synthesis. Food acquisition behaviors (e.g., what and how often food is purchased, changes in food purchases) were assessed by 26 studies, food preparation (e.g., cooking habits, intra-household distribution of responsibilities, preparation methods) by nine studies, and household consumption practices (e.g., timing, snacking, meal skipping, eating away from the home) by 30 studies. Most studies used quantitative methods (n=34), some used qualitative methods (n=13), and few used mixed methods (n=3). Likert scales and semi-structured interviews were the most used tools for quantitative and qualitative assessments, respectively. Across the 50 studies, 40 different tools were used to assess food-related behaviors and only 14 studies claimed using validated tools. Few studies included a full tool in text or in supplemental material (n=23). Currently, there is little alignment on how to assess food choice behaviors in South Asia, highlighting the need for a contextually adaptable repository of tools. Adapting and validating existing tools, rather than creating new ones, could improve efficiency, continuity, and comparability.
