Diets and dietary constituents that we consume have a considerable impact on disease risk. Intriguingly these effects may be modulated to some extent by sex. Lack of female representation in nutritional studies as well as a lack of stratification by sex has and continues to limit our understanding of these sex × diet interactions. Here we provide an overview of the current and available literature describing how exposure to certain dietary patterns (Western-style diet, Mediterranean diet, vegetarian/vegan, ketogenic diet) and dietary constituents (dietary fibre, PUFA and plant bioactive) influences disease risk in a sex-specific manner. Interestingly, these sex differences appear to be highly disease-specific. The identification of such sex differences in response to diet stresses the importance of sex stratification in nutritional research.

Dietary guidelines are increasingly promoting plant-based diets, limits on red meat consumption, and plant-based sources of protein for health and environmental reasons(1). It is unclear how the resulting food substitutions associate with insulin resistance, a risk factor for type 2 diabetes. Here, we modelled the replacement of red and processed meat with plant-based alternatives and the estimated effect on insulin sensitivity. We included 783 participants (55% female) from the Childhood Determinants of Adult Health (CDAH) study, a population-based cohort of Australians. In adulthood, diet was assessed at three time points using food frequency questionnaires: CDAH-1 (2004–06), CDAH-2 (2009–11), and CDAH-3 (2017–19). The median follow-up duration was 13 years. The cumulative average intake of each food group was calculated to reflect habitual consumption. Insulin sensitivity (%) was estimated from fasting glucose and insulin concentrations at CDAH-3 (aged 39–49 years) using homeostasis model assessment. Applying the partition model(2), we simulated the replacement of one food group with another by including both in the model simultaneously (e.g., red meat and legumes), along with potential confounders and energy intake. The difference between parameter estimates (i.e., regression coefficients and variances) and their covariance were used to estimate the “substitution” effect. We report the simulated percentage point change in log-transformed insulin sensitivity for a 1 serve/day lower intake of one food group with a 1 serve/day higher intake of another food group. Replacing red meat with a combination of plant-based alternatives was associated with higher insulin sensitivity (β = 0·10, 95% CI 0·04–0·16). Adjustment for waist circumference attenuated this association by 61·4%. On an individual basis, replacing red meat with legumes (β = 0·12, 95% CI 0·02–0·21), nuts and seeds (β = 0·15, 95% CI 0·06–0·23), or whole grains (β = 0·11, 95% CI 0·04–0·17) was likewise associated with higher insulin sensitivity. Point estimates were similar when replacing processed meat with plant-based alternatives, but more uncertain due to wide confidence intervals. Our modelling suggests that habitually replacing red meat, and possibly processed meat, with plant-based alternatives may associate with higher insulin sensitivity, and thus, a lower risk of type 2 diabetes. Abdominal adiposity was identified as a potentially important mediator in this relationship. In relation to insulin sensitivity, our findings support the recommendation to choose plant-based sources of protein at the expense of red meat consumption.

Diet is an important modifiable lifestyle factor for human health, and plant-rich dietary patterns are associated with lower risk of non-communicable diseases in numerous studies. However, objective assessment of plant-rich dietary exposure in nutritional epidemiology studies remains challenging. This study aimed to develop and evaluate metabolic signatures of the most widely used plant-rich dietary patterns using a targeted metabolomics method comprising of 108 plant food metabolites.

A total of 218 healthy participants from the POLYNTAKE cohort were included, aged 51.5 ± 17.7 years, with 24h urine samples measured using ultra-high-performance liquid chromatography–mass spectrometry. The validation dataset employed three sample types to test the robustness of the signature, including 24h urine (ABP cohort, n = 88), plasma (POLYNTAKE cohort, n = 195), and spot urine (TwinsUK cohort, n = 198). Adherence to the plant-rich diet was assessed using a priori plant- rich dietary patterns. A combination of metabolites that evaluates the adherence and metabolic response to a specific diet was identified as metabolic signature. We applied linear regression analysis to select the metabolites significantly associated with dietary patterns (adjusting energy intake), and ridge regression to estimate penalized weights of each candidate metabolite. The correlation between metabolic signature and the dietary pattern was assessed by Spearman analysis (FDR < 0.05).

The metabolic signatures consisting of 42, 22, 35, 15, 33, and 33 predictive metabolites across different subclasses were found to be associated with adherence to Amended Mediterranean Score (A-MED), Original MED (O-MED), Dietary Approaches to Stop Hypertension (DASH), Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND), healthy Plant-based Diet Index (hPDI) and unhealthy PDI (uDPI), respectively. The overlapping and distinct predictive metabolites across six dietary patterns predominantly consisted of phenolic acids (n = 38), including 14 cinnamic acids, 14 hydroxybenzoic acids, seven phenylacetic acids, and three hippuric acids. Six metabolites were included in all signatures, including two lignans: enterolactone-glucuronide, enterolactone-sulfate, and four phenolic acids: cinnamic acid, cinnamic acid-4'-sulfate, 2'- hydroxycinnamic acid, and 4-methoxybenzoic acid-3-sulfate. The established signatures were robustly correlated with dietary patterns in validation dataset (r = 0.13 - 0.40, FDR < 0.05).

We developed and evaluated a set of metabolic signatures that robustly reflected the adherence and metabolic response to plant-rich dietary patterns, suggesting the potential of these signatures to serve as an objective assessment of free-living eating habits.

The present paper provides an overview of the approach to developing food-based dietary recommendations in the UK. UK dietary recommendations are based on independent advice from the Scientific Advisory Committee on Nutrition (SACN). SACN's remit includes specific reference to the nutrient content of individual foods and advice on diet as a whole, including the definition of a balanced diet. SACN's approach is set out in its Framework for Evaluating Evidence and its assessments are supported by the data provided by the National Diet and Nutrition Survey. SACN's risk assessments have primarily focused on energy requirements, macro and micronutrients and/or the needs of specific population groups. However, dietary patterns or individual foods and health outcomes have been considered where sufficient evidence is available. An example of this is SACN's risk assessment on carbohydrates and health, which included consideration of evidence on sugar-sweetened beverages and the resulting dietary recommendations on free sugars and sugar-sweetened beverages led to a range of policies to reduce sugar intake in the UK, including the soft drinks industry levy. SACN has also recently published a position statement on processed foods and health. Government dietary advice is encapsulated in the UK's national food model, the Eatwell Guide. The Eatwell Guide shows the proportions in which different food groups should be consumed to have a well-balanced, healthier, more sustainable diet, to help meet nutrient requirements and reduce the risk of chronic disease. Any substantive change to government dietary advice is likely to lead to a review of the national food model.

Menopause is a natural developmental phase that all women go through from their early forties to mid-fifties, marking the transition from the reproductive to the non-reproductive years. This is characterised as the permanent cessation of menses due to progressive ovarian failure. Each woman's experience of the menopause is unique. Biopsychosocial changes occur during this time with some symptoms affecting up to 80 % of women and lasting for 4–5 years from the peri- to post-menopause. Reduced oestrogen may predispose some women to health issues following menopause, such as heart disease, diabetes, stroke and cognitive decline. It is vital to understand how to promote health and well-being to reduce the risk of developing chronic conditions in later life. Increased symptoms and concerns about health during the menopausal transition can be cues to action for some women to actively maintain their health. Menopause represents a window of opportunity to promote health, and to support women to make healthier lifestyle choices, part of the National Institute for Clinical Excellence guidelines for menopause management. Identifying appropriate strategies to change behaviour is less clear. Theories of behaviour change can provide frameworks to gain more insight into the facilitators and barriers to behaviour and can inform the researcher on what needs to change. This information can be used to inform the design, content, implementation and evaluation of a lifestyle intervention. This review paper will explore the impact of menopause on health and well-being generally, and the benefits of designing more effective theory-driven behaviour change interventions for menopause.

This method abstract details the Green School Program, piloted across three schools in maritime Fijian islands, addresses critical issues faced by Fijian and Pacific Island communities. These encompass malnutrition, food security, health hazards, and the urgency of integrating traditional knowledge, governance, and social-ecological systems approaches into creating healthier school environments. Non communicable diseases have emerged as a pervasive concern within Pacific Island communities, creating a challenge for public health systems, driven greatly by dietary habits(1). This complex health landscape underscores the need to safeguard traditional knowledge and agri-food practices and develop neo-traditional approaches to local food systems(2). Furthermore, the Green School Program recognizes the essential role of schools as community hubs, enabling enhancing heathy school environments by embracing traditional wisdom and sustainable farming practices and foods, ultimately empowering communities to address these multifaceted challenges(3). Developing the school environment as a sustainable setting for governance framework led by women and the school administration, rooted in traditional knowledge and practices. Additionally, it aims to design facilities that support efficient organic farming while integrating these into school activities. Economic sustainability through the sale of surplus farm products, as well as the enhancement of sustainable land-use management, health, wellbeing, and cultural identity. The program unfolds within a distinctive community-based framework with the establishment of robust governance, with a notable emphasis on the leadership of women and mothers who play a pivotal role in steering the green school initiative and ensuring community ownership. Collaborative governance spans multiple stakeholders, including school management, community-based school committees, youth groups, women groups, and traditional leaders. This inclusive engagement ensures both shared responsibility in program design and ownership during implementation phases. Sustainable facilities are strategically designed to include biodigesters, water storage and irrigation systems, composting, organic fertilizers, and seedling nurseries, enhancing the program’s capacity to create healthier school food environments while embracing traditional practices and values. The program has witnessed the active engagement of women in governance roles, promoting community unity and ownership. Traditional knowledge integration has enhanced crop diversity and sustainability. Economic sustainability has been achieved through surplus farm product sales, reducing dependency on external funding sources. Health improvements are evident, with reduced exposure to indoor air pollution from open fires. Cultural identity preservation and increased student engagement are also notable outcomes. The Green School Program’s holistic approach, rooted in traditional knowledge and sustainable practices, has yielded positive outcomes in governance, agriculture, nutritional food security, health, and cultural identity preservation. The program’s success demonstrates the potential for community-based initiatives to address critical issues and empower remote island communities. These results provide valuable insights into sustainable development approaches that prioritize community wellbeing and cultural heritage preservation in similar contexts.

Beans, peas and pulses offer significant nutritional, health and environmental benefits (1,2,3, 4) and the FAO states that including pulses in agrifood systems is key to achieving the Sustainable Development Goals(5). Recommended intakes vary across national food-based dietary guidelines(6), but higher intakes are associated with benefits including increased satiety, reduced blood pressure, lower risk of cardiovascular disease and improved gut microbiota composition and activity(7). Worldwide, the average consumption of pulses is 21g per person per day(8) but published analysis of UK intakes is scarce. The aim of this review was to analyse consumption trends using two UK government datasets.

The Family Food module of the Living Costs and Food Survey details food and drink purchases from approximately 5000 households per year(9). The ‘UK – household purchases’ data include the average (mean) quantities purchased per person per week. Categories relating to beans, peas and pulses were identified, and data were presented as graphs of purchasing trends (1974–2021).

The National Diet and Nutrition Survey (NDNS)(10) assesses the nutritional status of 1000 participants (1.5 years and over) annually. Personal-level dietary data (2008-2019) were evaluated for subgroups ‘baked beans’ and ‘beans and pulses including ready meal and homemade dishes’, including fresh, frozen and canned beans and pulses, and recipes containing them. Peas/ green beans were excluded because of the nature of the data aggregation. Food-level dietary data (2018-19) were assessed for the frequency of consumption of different types of peas, beans and pulses.

Our analysis of the Family Food datasets shows that, at 28g per person per day, the current average (mean) consumption of beans, peas and pulses in the UK is suboptimal. Our parallel analysis of NDNS data showed that more than 40% of participants were not eating any beans and pulses (excluding peas).

Dietary trends are shifting. The overall consumption of beans, peas and pulses has been falling steadily since the late 1980s. This is mostly due to the drop in consumption of peas and baked beans, though these are still the most frequently consumed legume categories in the UK diet. Canned pea purchases fell from 88g per person per week in 1974 to 14g per person per week in 2020-21. Baked bean purchases peaked at 133g per person per week in 1986, dropping to 78g in 2020-21.

Purchases of other canned beans and pulses (excluding baked beans) have increased noticeably in the last decade, from 17g per person per week 2015-16 to 32g in 2020-21. Purchases of dried pulses have remained consistent, averaging 11g per person per week in 2020-21.

This analysis indicates significant scope to deliver affordable, accessible health and environmental benefits through increased consumption of beans, peas and pulses in the UK.

Doctors’ and nurses’ (DNs) wellbeing in the National Health Service is important for safe healthcare for those in need. However, their demanding duties, including irregular shift work, can significantly impact their health. Unfortunately, irregular working patterns are associated with higher sickness rates and stress among healthcare professionals due to the inherent challenges of the work(1,2). For example, shift work disrupts sleep and impairs cognitive function and performance, leading to poorer physiological and cardiovascular health(3), workforce shortages and difficulties adapting to a consistently demanding workload, which can impact patient care delivery(4). Despite the importance of workplace health and nutrition for DNs, our understanding of their dietary practices during shift work remains limited. Therefore, gaining insights into DNs’ eating habits during shifts is imperative to supporting their health. Our research aimed to understand DNs’ eating practices during their work, including the types of food consumed throughout the day.

Online semi-structured interviews (n=16) were conducted with a convenience sample of current practising medical doctors (n=11) and nurses (n=5) in England. This provided an opportunity to compare and contrast the research data between DNs on workplace nutrition. All participants did shift work, encompassing varied working patterns, including day and night shifts, short and long days and weekends. Following Braun and Clarke’s(5) approach, an inductive thematic analysis presented the findings.

Results elucidate six areas of DNs’ eating practices and dietary intake: before and during shifts, on long shifts, after shifts, during night shifts, and on non-working days. Our data suggests that DNs prioritise their clinical responsibilities over their dietary intake at work. Consequently, they often miss eating opportunities and consume caffeine to stay alert during their shifts. Furthermore, DNs viewed night shifts as involving less healthy food choices. While participants expressed their intention to eat healthily during their shifts, their clinical responsibilities made maintaining regular and nutritious dietary practices throughout the day challenging. Nevertheless, DNs value their meal after a shift as the most important, as this could be the only meal they eat throughout the day.

Our results suggest that DNs’ eating practices and dietary intake are sub-optimal to recommended dietary guidelines. It also suggests that eating practices are varied, individualised and not applicable to all, considering the many environmental and occupational factors contributing to DNs’ nutritional behaviours. Therefore, dietary workplace interventions are recommended to improve DNs’ dietary behaviours at work. Future research should explore DNs’ eating practices through follow-up interviews at various time points. This approach will provide valuable insights into DNs’ dietary and nutritional behaviours during shift work, helping to uncover additional barriers and challenges beyond DNs’ daily experiences.

Utilising local and traditional foods in schools presents a significant opportunity within our region to ensure food and nutritional security, support local livelihoods by driving markets and employment opportunities, increasing food literacy, and help students to understand the role of, and develop a preference for these foods. School meals programs (SMP) are increasingly touted as a strategy for food system transformation(1), however, are not widely used in the Pacific Islands(2). Yet, there is increasing interest and momentum towards understanding school food and nutrition environments and the use of SMP in this region, especially with models that support and promote the integration of local, traditional climate-resilient, nutrient rich foods. When a large scale SMP may not be possible, other school food and nutrition activities can be utilised to support nutritious food choice. Evidence collected over the last five years provides information on the current situation, activities, and capacity for providing food in schools across the Pacific Islands (2,3,4). Activities across the region vary from national SMP to gardening programs, nutrition education, providing canteens/tuckshops and other ad hoc activities, for example events for World Food Day. Some activities have a requirement for the use of local food, while some prioritise local foods in gardening programs and work with local farmers. Recently it has been shown that youth are exposed to, and have access to significant amounts of ultra-processed foods (UPF) around schools(3). Mapping of the foods available to students within a 400m radius of 88 schools in Fiji found that sugar sweetened beverages were available in 80%, and lollies/confectionary in just over 60% of outlets. Fresh fruit was available in just over 20% of outlets, while fresh vegetables were available in less than 20% of outlets(3). While there are many challenges to providing local, traditional, nutritious foods in schools, including access to financial, human, and physical resources, stakeholders have told us that one of the most significant is how modernisation and colonisation of food systems have resulted in a preference for hyperpalatable UPF and how this makes it more challenging to incorporate local produce in a way that is accepted by students. This provides an opportunity to further explore and share ways to integrate local, traditional, climate-resilient, nutrient rich foods in schools to support children and adolescents to value, utilise, prefer, and advocate for these foods. There is a need to support the utilisation of traditional, local foods in schools by advocating for policy (at various levels, right from a school level upwards) that drives the use of these foods and creates more supportive school food environments.

Irritable bowel syndrome (IBS) is a chronic and relapsing gastrointestinal condition which negatively impacts quality of life(1). Dietary triggers are common and dietary management is central to the IBS treatment pathway with dietitians being the main education providers for patients(2). The aim of this study was to explore the perceptions of dietitians towards current practices in IBS services in clinical settings across the UK.

Qualitative semi-structured interviews were undertaken to explore current practices, barriers, and facilitators to dietetic practice and expected treatment outcomes. Eligible participants were dietitians specialising in IBS and working in the National Health System (NHS) in the UK. Interviews were held virtually. Audio was recorded and transcribed following intelligent transcription. Data were analysed using template analysis (3).

Thirteen dietitians (n=12 female) specialising in gastroenterology consented to participate in the study. Dietitians were working in various NHS Trusts across the country (Southeast England n=3; Southwest England n=3; Northwest England n=2; Northeast England n=1; West Midlands n=1; Southwest Wales n=1 and Southcentral Scotland n=2). Ten out of 13 dietitians had more than five years of experience in IBS management. Three main themes emerged: 1) Dietetic services as part of IBS referral pathways; 2) Practices in relation to dietetic services and 3) Implications of services on patients’ expectations and feelings. Each main theme had subthemes to facilitate the description and interpretation of data. The increasing number of IBS referrals to dietitians and the need for accurate and timely IBS diagnosis and specialist IBS dietitians was reported, alongside the use of digital innovation to facilitate practice and access to dietetic care. The use of Internet as a source of (mis)information by patients and the limited time available for educating patients were identified as potential barriers to dietetic practice. Dietitians follow a patient-centred approach to dietary counselling and recognise the negative implications of perceived IBS-related stigma by patients on their feelings and treatment expectations.

The study identified areas and practices which can facilitate access to dietetic services and patient- centred care in IBS management as outlined in guidelines (4).

The increasing rates of obesity among children and adolescents are significant issues worldwide and in the Pacific Island Nations(1). An energy imbalance between calorie intake and expenditure is linked to overweight and obesity for children and adolescents. Epidemiological, nutritional, and technological changes are linked to altered eating habits, including an increase in energy consumption. Conversely, technological advancements and market globalization are responsible for declines in physical activity (PA)(2). During COVID-19 outbreak a more sedentary lifestyle than before the outbreak has been adopted by children and adolescents as a result of lockdown measures, which include shutting of schools, restrictive travel outside the home, and limiting social interactions has made the issue worse(3). Studies have shown that 40% to 70 % of obese children become obese adults(4). Since children spend a large portion of their day in school and eat their main meals there, school settings are suitable for interventions aimed at preventing childhood obesity. Additionally, school environments will reduce the number of dropouts brought on by problems with accessibility or transit(5). The selection of primary school children is important for interventions as the dietary and physical activity habits acquired at this age are ingrained in children and continue into adulthood. So, it is important to have a robust nutrition and physical activity curriculum in all the primary schools. There are many challenges faced by the governments in implementing such curriculum which includes lack of trained in country staff, limited infrastructures in schools for physical activity, culturally relevant information which can be easily understood by local populations, proper monitoring, and evaluation of the existing guidelines. Community engagement and partnership with local health ministries and departments are crucial for the success of these curriculum (6). To fill this gap robust evidence on effectiveness and implementation of school-based wellness intervention programs in primary schools are in dire needs in Pacific Island nations. Given this, the project titled “Healthy Child Promising Future-Promoting health in primary school settings was conducted in all schools in Wallis & Futuna and piloted in one urban school in Fiji. A knowledge, attitude, practice (KAP) questionnaire was used to evaluate the effectiveness of the intervention which was conducted for all the children (7-9 years) and their care takers. Intervention was conducted on 15 pre identified themes by face-to-face sessions every week and 30 minutes physical activity session was conducted every day in all the schools for children. For caretakers intervention was conducted around 5 themes. In both the countries the intervention had shown significant improvement in KAP scores both for caretakers and children related to the healthy diet consumption and promotion of physical activity. The results indicate that the developed intervention package had a positive impact on KAP.

Childhood obesity and overweight rates in New Zealand are considerably higher than that globally with one in three children aged between 2-14 years being overweight or obese(1). Children’s dietary knowledge and food preferences are influenced by various factors including the food environment. Schools are an excellent setting to influence children’s dietary behaviours since they have the potential to reach almost all children during the first two decades of their lives. However, previous analyses indicate many school canteens and food providers do not supply foods that promote healthy eating and nutrition behaviours (2,3). The Ministry of Health (MoH) recently implemented a ‘Food and Drink Guidance for Schools’ which utilises a traffic-light framework dividing foods into three categories: ‘green’, ‘amber’, and ‘red’(4). The aim of this study was to assess primary school canteen food menus against the newly implemented MoH Guidance. A convenience sample of 133 primary school canteen menus were collected in 2020 as part of the baseline evaluation of the Healthy Active Learning initiative across New Zealand. Four researchers (three nutritionists and one dietitian) developed a menu analysis toolkit to undertake the analysis of all menus collected. The toolkit provided a breakdown of commonly packaged foods and meals/menu items available to purchase within schools based on Health Star Ratings, ingredients, and/or standard recipes. Assumptions were created for menu items requiring additional detail to be categorised according to the guidance through consensus by all four researchers. Primary school menus were coded by two researchers, and intercoder reliability was ensured by independent coding and cross-checking of 10% of menus. Descriptive and inferential analyses were conducted using IBM SPSS and P<0.05 denoted significance. Analyses of canteen menus revealed that most menu items belonged to the less healthy amber (41.0%) and red (40%) food categories. Low decile schools had a lower percentage of green food items (8.6%) and a higher percentage of red food items (48.3%) compared to high decile schools (p = 0.028). Similarly, schools in low deprivation areas had a significantly higher percentage of green food items (14.2%) compared to high deprivation areas (8.6%) (p = 0.031). Sandwiches, filled rolls, and wraps were the most commonly available items (86%) followed by baked foods and foods with pastry (71%). Sugar-sweetened beverages were just as prevalent as water on school food menus (54% each). Over half of in-house catered canteen menu items were classified as 'red’ foods (55.3%). This study highlights that most school canteens were not meeting the guidelines for healthy food and drink provision outlined by the MoH. Improving school food availability for children in socioeconomically deprived areas needs to be prioritised to reduce inequities. Findings suggest the need for more robust national policies and mandated school guidance to improve the food environments in New Zealand schools.

Non-communicable diseases (NCDs) are the predominant cause of death in the UK(1) and place an economic burden on societies(2). An unhealthy diet is one of the four main behavioural risk factors for NCDs(3) and thus, interventions targeting dietary behaviour are of particular interest in the prevention of NCDs. The workplace may be a valuable setting for these interventions as employees represent a large proportion of the population in the UK(4). In the male population, NCDs and several risk factors typically manifest at a younger age(5) and, additionally, males participate less in health-promoting activities(6).

The aim of this scoping review was to identify and characterise the evidence base to determine if a future full systematic review on nutrition interventions in the workplace to improve health and well- being in males is feasible.

The review was conducted adhering to the PRISMA guideline for Scoping Reviews(7). Three electronic databases (Ovid, PubMed, and The Cochrane Library) were systematically searched for relevant publications responding to the research question from inception. No restrictions were made in the search and all study types were eligible. Articles that were not available in English were excluded from the review. Eligible studies were reviewed using a pre-defined data extraction form and references hand-searched for relevant publications. Data synthesis was focused on describing application-oriented aspects and outcome analyses were reduced to anthropometric outcomes.

Of the 1,224 publications from the initial database search, 46 were included in the review, with an additional 15 studies identified from hand-searching, resulting in 61 included reports on 57 interventions. Four main approaches to nutrition interventions at the workplace were identified; educational, environmental, individual counselling, and meal provision/replacement. Most interventions used multicomponent approaches. One of the 61 included reports followed a qualitative design. Anthropometric outcomes were reported in the majority (83.6%) of studies, followed by bioclinical outcomes (45.9%), other outcomes were food (34.4%) and nutrient intake (22.9%), smoking habits (14.8%) and, one study reported on Quality of Life. Of the studies reporting anthropometric outcomes 69% reported to be effective in improving body weight, 47.8% BMI and 54.5% waist circumference. No determinants of successful interventions such as type, duration, workplace participation were identified.

This review suggests that nutrition interventions at the workplace are effective in improving several anthropometric outcomes. A future full systematic review is feasible but should consider narrowing the research question to account for limitations in the current evidence base as differences in reporting of design, population, intervention, and outcomes severely limited data analyses. Furthermore, to enable high-quality research, the development of a reporting tool, such as the TIDieR checklist (8) is recommended.

Shifting dietary protein intakes from animal to plant-based sources is suggested as a path to sustain the world’s food consumption and maintain planetary resources (1). However, to facilitate change, it is important to characterise baseline dietary protein patterns. This study aimed to examine dietary protein intakes on the island of Ireland in order to determine population characteristics and food sources influencing protein intake.

Analyses were performed on the Northern Ireland sub cohort of the UK National Dietary Nutrition Survey (NDNS 2016-2019) (2) and the Irish National Adult Nutrition Survey (2008-2010) (3). Both surveys used a four-day food diary and a final sample of 1484 adults, aged 18-64 years was extracted (NANS; n =1274 and NI NDNS; n=210). Mean daily intakes for protein (MDI; % total energy, TE) for the total population were calculated and the population was divided into three tertile groups based on low, medium and high protein intake (%TE). Differences in population characteristics, energy MDI, key nutrients (%TE or per 10MJ) and contributing food sources were examined across these tertiles, using chi-square and one-way ANOVA with covariates (age and BMI) and correcting for multiple comparisons as appropriate (P<0.005).

Overall, 17.1% of TE was obtained from protein and 77% of participants met their protein DRV based on EFSA recommendations of 0.83g/kg/body weight (4). The difference in protein intakes between the highest and lowest tertiles was 7.8% TE (21.2 % TE vs 13.4% TE) with high protein consumers reporting lower energy intakes (1734 ±564kcal) compared to low consumers (2185± 661 kcal). High protein consumers were older (42.5 ± 12.8 years) and had a higher BMI (27.7 ± 6.0 kg/m2). They also had higher MDI of dietary fibre, calcium, zinc, sodium, iron, folate and vitamins A, C, D and B12 (per 10MJ) (p<0.001) and lower MDI of carbohydrates, fat, saturated fat (%TE) in comparison to low consumers (p<0.001). The % contribution of ‘chicken, turkey and dishes’ (18.3%), ‘beef, veal and dishes’ (12.8%) and ‘fish and fish products (7.0%) to protein intakes were significantly higher in the high versus the low consumption group (10%, 7.4%, 4.4% TE respectively; P<0.001). In contrast, those in the lowest protein intake group had a significantly higher intakes of protein coming from dietary sources including ‘burgers, sausages and meat products (9.9 vs 5.9%), ‘white bread and rolls’ (6.9 vs 3.9%), ‘potatoes (including chips)’ (4.1 vs 2.9 %) and ‘cakes, pastries, buns and fruit pies’ (1.7 vs 0.8%) compared to high consumers.

In general, animal protein sources contributed more to total daily protein intakes than plant sources, however, the pattern of protein foods differed according to level of protein intake. These findings will aid in the development of strategies to diversify protein intakes on the Island of Ireland.

Human nutrition is a key component of the definitions of both sustainable food systems and sustainable healthy diets, and features prominently in the Sustainable Development Goals. However, progress towards complete nutrition and food security for the entire global population is poor, and the burden of malnutrition and food insecurity is felt in countries of all income levels, including in Oceania. While countries like Australia and New Zealand (NZ) are widely perceived as sources of high-quality food exported overseas due to great surpluses above national requirement, this hides domestic issues. The international nutrition community recognises and are demanding that our food systems must be sustainable, which is not yet the case anywhere in Oceania. Food insecurity at the household level is not uncommon, nor are nutrient deficiencies. It is often presumed that, should the inequitable distribution of food be balanced, these challenges would disappear. However, food supply and trade data show that even at the national and regional levels, insufficient food and nutrient supplies to meet population requirements are the established norm. For example, it has been demonstrated that domestic vegetable production falls short of NZ dietary recommendations, with imports making a negligible difference other than via energy dense crops(1). Likewise, after consideration of trade, NZ has undersupplies of calcium, potassium, vitamins C and E, and dietary fibre compared to population requirements(2). A wealth of data exists quantifying food production, trade, and availability and various scales. Increasingly, researchers are matching these to human requirements, whether at the food or nutrient level, to identify gaps(3). Insights generated from these data-driven approaches are being directed at trade policy, enabling decisions that can realise aspirational goals to reduce food insecurity through international trade. Making this data accessible to all via interactive user interfaces promotes wider engagement, understanding, and dissemination of findings. It also allows stakeholders in various countries to identify their own vulnerabilities, both as a result of current undersupplies, and due to high reliance on trading partners for food and nutrition security. Trade data can also be connected to environmental measures to identify scenarios where trade can be leveraged to the benefit of both nutrition and broader sustainability goals(4). High level, data driven approaches are not a substitute for individual-based studies on nutrition, but are a useful complement to them. With regionally or nationally deficient food and nutrient supplies, complete nutrition for individuals cannot be attained. A holistic, system-wide understanding is necessary for any policy decisions to advance nutrition.

Inflammatory Bowel Diseases (IBD) are chronic intestinal disorders, characterised by periods of quiescent disease and episodes of heightened disease activity. The diseases mainly affect the gastrointestinal tract.
