While there are existing literature reviews focusing on antinutritional compounds, particularly on their reduction, this review aims to provide a comprehensive description of antinutrients for producers, food scientists, professionals, legislators and consumers, emphasising the complexity of the subject and the necessity for diverse approaches while identifying aspects that still require further research. Antinutrients, including protease inhibitors, amylase inhibitors, phytic acid, lectins, saponins, tannins, cyanogenic glycosides, oxalic acid, polyphenols, goitrogens and pyrimidine glycosides, are described, encompassing various aspects such as their structural characteristics, analytical detection methods, distribution, physiological impacts and strategies for mitigation or elimination. Specifically, our review concentrates on assessing the presence of antinutrients in plant-based food products and the primary ingredients, categorised into five distinct groups, cereals, pseudocereals, pulses, seeds and nuts, which are commonly used in their production. Among these categories, legumes are identified as the richest source of anti-nutritional compounds, followed by cereal grains. However, certain pseudocereals, seeds and nuts also demonstrate high levels of specific antinutrients. While antinutrients are generally regarded as harmful to nutrient absorption, recent studies have revealed some potential health benefits associated with them. Therefore, further in vivo research is essential to elucidate the behaviour of antinutritional compounds within the human body. Additionally, there is a significant lack of formal regulations and guidelines regarding antinutrients, and food products currently do not feature labelling related to these compounds.</p>","PeriodicalId":48536,"journal":{"name":"Nutrition Bulletin","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143081699","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The concentration of food insecurity in both socioeconomically disadvantaged groups and households containing children raises concerns about its uneven nutritional and health impacts across different groups. In parallel with rising food insecurity over the past decade, concerns about the environmental consequences of human diets are intensifying, where urgent changes are needed to people's diets to avoid irreversible environmental damage. It is generally assumed that cost has a significant impact on people's ability to adopt more environmentally sustainable food practices. This UK Research Council-funded project seeks to gain insights into the ways in which low-income mothers (are able to) engage with environmentally sustainable food practices. RQ1 will examine the day-to-day food practices that mothers undertake for their families to offer insights into everyday food insecurity and the relevance of environmentally sustainable food practices. RQ2 will explore biographical experiences to highlight how mothers' life histories influence their familial food practices, including their current household food security and engagement with environmentally sustainable food practices. Finally, RQ3 will explore mothers' upcoming prospects of food insecurity and environmentally sustainable food practices. These research questions will be explored through a qualitative longitudinal, feminist study of 15 low-income mothers in Sheffield, UK, combining in-depth interviews with ethnographic elements. Gaining improved knowledge of mothers' food practices on a low income will be valuable to influence realistic, effective and meaningful philosophies, policies and practical action that prioritises equity, good nutrition and environmentally sustainable food practices.</p>","PeriodicalId":48536,"journal":{"name":"Nutrition Bulletin","volume":" ","pages":"550-560"},"PeriodicalIF":4.6,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142298932","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Participants explored the challenge of the complexity of balancing nutrition and planetary goals, emphasising the need to navigate trade-offs between various dimensions of sustainability. Whilst recognising the global nature of the issue, the roundtable primarily focussed on a UK perspective. The discussion highlighted the urgency of transforming the food system to achieve net zero, whilst ensuring broader environmental benefits, nutritional adequacy and dietary and health equity across all life stages. Concerns about poor dietary patterns, particularly among vulnerable groups were raised, with participants stressing the need for policies that promote healthy, sustainable and equitable diets without worsening inequalities. These policies should also enhance livelihoods and community wellbeing, foster resilience and support local economies. On the supply side, participants called for better data within the agri-food system, particularly at the farm level. They advocated for a multidimensional, holistic approach that goes beyond greenhouse gas emissions to encompass wider environmental impacts and whole-farm benefits, such as enhancing soil health, promoting biodiversity, improving water management, supporting nutrient cycling and boosting farm-level resilience through diversified cropping systems. Roundtable participants acknowledged existing recommendations to reduce meat consumption for both environmental reasons, such as land use and greenhouse gas emissions, and health concerns, as evidence links red, particularly processed, meat consumption with increased colorectal cancer risk. Given the variation in meat consumption globally and even locally between individuals, the discussion explored the potential of targeted campaigns to reduce high meat intake, along with the role of public food procurement and the food industry in decreasing processed meat consumption. The consensus was that dietary changes must be framed within the context of a balanced diet and broader sustainability concerns. Despite some differing viewpoints on implementation, participants agreed that transitioning to healthier, more sustainable diets is a priority. Collaboration across the entire food chain, from farm to fork, with investment in innovation, robust data collection and research, alongside policy support, was emphasised as essential to achieving this goal.</p>","PeriodicalId":48536,"journal":{"name":"Nutrition Bulletin","volume":"49 4","pages":"572-598"},"PeriodicalIF":2.7,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142630625","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the effect of nutrition policies on those experiencing FI in the context of the current cost-of-living crisis needs to be better understood. The aim of the Diet and Health Inequalities (DIO Food) project is to work with early years, people living on a low income and retailers to generate opportune evidence-based research and commentary that will inform diet-related health inequalities policy and practice. DIO Food is related to the existing Food Insecurity in people living with Obesity (FIO Food) project, which consists of four interlinked work packages (WPs1-4). DIO Food consists of three interlinked work packages (WPs5-7), which enhance the scope of FIO Food, and are described in this article.

However, while serum B12 serves as a conventional biomarker for assessing B12 status, its utility is limited given its sensitivity and specificity in ascribing physiological deficiency of B12 and the functional vitamin B12 status of those adhering to vegan diets is unclear. We conducted a systematic review and meta-analysis using data based on the full panel of biomarkers of vitamin B12 status to test whether adherence to a vegan diet is associated with an elevated risk of functional vitamin B12 deficiency compared to vegetarian or omnivorous diets. In addition, subgroup analysis was carried out to look at the effect of vitamin B12 supplement use on B12 status among vegans.
