BackgroundThere are many constraints to conducting national food consumption surveys for national nutrition surveillance, including cost, time, and participant burden. Validated web-based dietary assessment technologies offer a potential solution to many of these constraints. ObjectiveThis study aims to investigate the feasibility of using a previously validated, web-based, 24-hour recall dietary assessment tool (Foodbook24) for nutrition surveillance by comparing the demographic characteristics and the quality of dietary intake data collected from a web-based cohort of participants in Ireland to those collected from the most recent Irish National Adult Nutrition Survey (NANS). MethodsIrish adult participants (aged ≥18 years) were recruited to use Foodbook24 (a web-based tool) between March and October 2016. Demographic and dietary intake (assessed by means of 2 nonconsecutive, self-administered, 24-hour recalls) data were collected using Foodbook24. Following the completion of the study, the dietary intake data collected from the web-based study were statistically weighted to represent the age-gender distribution of intakes reported in the NANS (2008-2010) to facilitate the controlled comparison of intake data. The demographic characteristics of the survey respondents were investigated using descriptive statistics. The controlled comparison of weighted mean daily nutrient intake data collected from the Foodbook24 web-based study (329 plausible reporters of a total of 545 reporters) and the mean daily nutrient intake data collected from the NANS (1051 plausible reporters from 1500 reporters) was completed using the Wilcoxon–Mann-Whitney U test in Creme Nutrition software. ResultsDifferences between the demographic characteristics of the survey participants across the 2 surveys were observed. Notable differences included a lower proportion of adults aged ≥65 years and a higher proportion of females who participated in the web-based Foodbook24 study relative to the NANS study (P

The childhood years represent a period of increased nutrient requirements during which a balanced diet is important to ensure optimal growth and development. The aim of this study was to examine food and nutrient intakes and compliance with recommendations in school-aged children in Ireland and to examine changes over time. Analyses were based on two National Children's Food Surveys; NCFS (2003–2004) (n 594) and NCFS II (2017–2018) (n 600) which estimated food and nutrient intakes in nationally representative samples of children (5–12 years) using weighed food records (NCFS: 7-d; NCFS II: 4-d). This study found that nutrient intakes among school-aged children in Ireland are generally in compliance with recommendations; however, this population group have higher intakes of saturated fat, free sugars and salt, and lower intakes of dietary fibre than recommended. Furthermore, significant proportions have inadequate intakes of vitamin D, Ca, Fe and folate. Some of the key dietary changes that have occurred since the NCFS (2003–2004) include decreased intakes of sugar-sweetened beverages, fruit juice, milk and potatoes, and increased intakes of wholemeal/brown bread, high-fibre ready-to-eat breakfast cereals, porridge, pasta and whole fruit. Future strategies to address the nutrient gaps identified among this population group could include the continued promotion of healthy food choices (including education around 'healthy' lifestyles and food marketing restrictions), improvements of the food supply through reformulation (fat, sugar, salt, dietary fibre), food fortification for micronutrients of concern (voluntary or mandatory) and/or nutritional supplement recommendations (for nutrients unlikely to be sufficient from food intake alone).

Dietary changes are required to mitigate the climatic impact of food consumption. Food consumption databases can support the development of sustainable food based dietary guidelines (SFBDG) when linked to environmental indicators. An improved knowledge base is crucial to the transition to sustainable diets, and multiple environmental indicators should be considered to ensure this transition is evidence based and accounts for trade-offs. The current study aimed to quantify the environmental impact of daily diets across population groups in Ireland. Nationally representative food consumption surveys for Irish children (NCFSII; 2017–2018), teenagers (NTFSII; 2019–2020), and adults (NANS; 2008–2010) were used in this analysis. Blue water use (L) and greenhouse gas emissions (GHGe; kgCO2eq) were assigned at food level to all surveys. Cropland (m2), nitrogen (kgN/t), and phosphorous use (kgP/t) were assigned at the agricultural level for adults. Multiple linear regressions, Spearman correlations, and ANCOVAs with Bonferroni corrections were conducted. Higher environmental impact diets were significantly associated with demographic factors such as age, education status, residential location, and sex, but these associations were not consistent across population groups. The median greenhouse gas emissions were 2.77, 2.93, and 4.31 kgCO2eq, and freshwater use per day was 88, 144, and 307 L for children, teenagers, and adults, respectively. The environmental impact of the Irish population exceeded the planetary boundary for GHGe by at least 148% for all population groups, however the boundary for blue water use was not exceeded. Meat and meat alternatives (27–44%); eggs, dairy, and dairy alternatives (15–21%); and starchy staples (10–20%) were the main contributors to GHGe. For blue water use, the highest contributors were meat and meat alternatives in children; savouries, snacks, nuts, and seeds in teenagers; and eggs, dairy, and dairy alternatives in adults (29–52%). In adults, cropland use, nitrogen use, and phosphorous use exceeded planetary boundaries by 277–382%. Meat, dairy, and grains were the main contributors to cropland, nitrogen, and phosphorous use (79–88%). The quantified environmental impact of Irish diets provides a baseline analysis, against which it will be possible to track progress towards sustainable diets, and the basis for the development of Sustainable Food Based Dietary Guidelines in Ireland.

Summary: Background: Overweight and obesity in adolescence is a growing issue and can have a range of both short‐ and long‐term consequences on health. Objectives: To analyse trends in adolescent weight status in Ireland across a 30‐year period and to examine the influence of sociodemographic factors on overweight/obesity in Irish adolescents over time. Methods: Body composition and body mass index weight status of Irish adolescents were compared using data from three nationally representative, cross‐sectional Irish national food consumption surveys from 1990, 2006 and 2020. Adjusted analysis of associations between socio‐demographic factors with the risk of adolescent overweight/obesity at each time point were examined. Results: The prevalence of Irish adolescents with overweight/obesity has increased significantly in recent years, with 24% of adolescents living with overweight/obesity in 2020 compared to 18% in 2006 and 13% in 1990 (p < 0.001). Of note is a substantial increase in the prevalence of obesity, with 8% of adolescents living with obesity in 2020 compared to 3% in 2006 and 0.5% in 1990 (p < 0.001). A lower affluence social class was associated with 3.95 increased odds of adolescent overweight/obesity (95%CI 2.06–7.61) (p < 0.001) in 2020 only, with 41% of adolescents from the lowest affluence social class affected by overweight/obesity. Parental education level was inversely associated with the risk of adolescent overweight/obesity in 2006 and 2020, with a stronger effect in 2020. Conclusion: There is an increasing prevalence of adolescents living with overweight/obesity in Ireland, with evidence of a growing socioeconomic gradient of overweight/obesity where adolescents affected by socioeconomic disadvantage are most at risk.

The dietary role of meat is under scrutiny for health and environmental reasons, yet a growing body of evidence proposes that advice to limit red meat consumption is unnecessarily restrictive. The aim of this study was to investigate the role of 'fresh beef and lamb' in the diet of the population (5–90 years) in Ireland and its association with markers of nutrition and health status. Analyses are based on data from three nationally representative dietary surveys in the Republic of Ireland. Dietary intake data were estimated using food records, and nutrient intakes were estimated based on UK and Irish food composition tables. Biochemical samples were collected and analysed using standard procedures. 'Fresh beef and lamb' (defined as beef/lamb that had not undergone any preserving process other than chilling/freezing/quick-freezing) was consumed by 68–84% of the population and intakes ranged from 19 to 43 g/d across age groups. It made important contributions to intakes of protein, monounsaturated fat, vitamins D, B12, niacin, iron and zinc while also contributing relatively small proportions of total fat, saturated fat and salt. Higher consumption of 'fresh beef and lamb' was associated with higher intakes of protein, niacin, vitamins B6, B12, zinc and potassium (but also total fat) and lower intakes of carbohydrate and total sugars (but also dietary fibre). In adults, older adults and WCBA, higher consumption of 'fresh beef and lamb' was not associated with increased risk factors of cardio-metabolic diseases nor was it associated with better or poorer nutritional status for vitamins D, B12 or iron. This study adds to the evidence base on the contribution of 'fresh beef and lamb' in the diet and may be useful to policymakers updating guidance for healthy diets from sustainable food systems.

Selenium (Se) is an essential trace element which has an important role as a constituent of seleno-proteins involved in various physiological processes. Previous research in Irish adults suggests that intakes of this important nutrient are suboptimal. The aim of the present study was to estimate the current intakes and major food sources of Se by Irish adults. Mean daily intakes (MDIs) of Se were calculated using data from the National Adult Nutrition Survey which involved 1500 Irish adults aged 18–90 years. The Se content of foods and drinks consumed over a 4-d period was determined using data from the Irish Total Diet Study (TDS). Adequacy of Se intakes was assessed by calculating the proportion of the population with intakes below the adequate intake (AI) of 70 μg/d and lower reference nutrient intake of 40 μg/d (LRNI). The MDI of Se in the total population was 71⋅7 μg/d, with significantly higher intakes reported in men (80⋅2 μg/d) compared with women (63⋅4 μg/d, P < 0⋅01). Meat and meat products were the major contributing food group to Se intakes for both men (37 %) and women (31 %). Overall, 47 % of the population were not meeting the recommended AI, while 4 % of the total population were not meeting the LRNI. Although the average intake of Se is above the AI, a significant proportion of the population is not meeting this recommendation and continued monitoring of Se intakes is necessary, particularly by at-risk groups and also in the context of sustainability.

Summary: Background: Investigations into the main drivers of childhood obesity are vital to implement effective interventions to halt the global rise in levels. The use of a composite score may help to identify children most at risk of overweight/obesity. Objectives: To investigate the cumulative impact of factors associated with overweight/obesity risk in children. Methods: Data were analysed from the Irish National Children's Food Survey II which included 600 children, aged 5–12‐years. The risk factors examined included social class, parental, early life, lifestyle, and dietary components. A composite score was calculated which ranged from 0 (no risk factors for overweight/obesity) to 4 (4 risk factors for overweight/obesity). Results: In model 1 (%BF) the four factors associated with overweight/obesity risk were having a parent with overweight/obesity (odds ratio 3.1; 95% confidence interval 1.9–4.8), having a high birth weight of ≥4 kg (2.5; 1.6–3.9), being from a low social class (2.3; 1.4–3.8) and low physical activity (1.9; 1.2–2.8). Children who scored 3–4 points on the composite score had a 10‐fold (10.0; 4.2–23.9) increased risk of overweight/obesity compared to those with 0 points, a sevenfold (7.2; 3.9–13.5) increased risk compared to those with 1 point and a threefold (2.6; 1.4–4.8) increased risk compared to those with 2 points, with similar results observed in model 2 (BMI). Conclusion: The use of a composite score is a beneficial means of identifying children at risk of overweight/obesity and may prove useful in the development of effective interventions to tackle childhood obesity.

Plant-based (PB) diets are associated with good health and are also recommended for environmental sustainability. The present review aimed to summarise the definitions of PB diets globally and to investigate the nutritional role of PB diets in adults. This review found that there is a wide range of PB definitions ranging from the traditional vegetarian diets (including vegan) to semi-vegetarian/flexitarian diets. Furthermore, other diets which were originally developed due to their associations with positive health outcomes, such as the portfolio, Mediterranean-style, DASH, healthy US-style, planetary health and Nordic-style diets, have been encompassed in PB definitions due to their emphasis on certain PB components. This review has highlighted that those consuming a PB diet are more likely to meet recommended intakes for carbohydrate, dietary fibre and vitamin E and are less likely to meet recommendations for protein, vitamin B12 and iodine compared to omnivores. Regardless of consumer type, neither PB consumers nor omnivores met recommendations for intakes of vitamin D, calcium and sodium. While intakes of protein, n-3, iron and zinc were generally sufficient from the PB diet, it is important to acknowledge the lower bioavailability of these nutrients from PB foods compared to animal-derived products. As dietary patterns shift towards a more PB diet, there is a need for further studies to investigate the role of PB diets for nutritional adequacy and status in populations currently accustomed to consuming a primarily omnivorous diet.

Peptide fractions rich in residues from the amino acid cysteine appear to increase non-haem iron absorbtion in meat. This appear to be the cause behind the 'meat factor,' or the reason why cellular animal proteins enhance the bioavailability of non-haem iron, while plant, milk and egg proteins do not., It is well established that the bioavailability of non-haem iron from foods is enhanced by the presence of meat. However, the nature of the promoter in meat has not yet [...]

Objective: To examine current dietary fat intakes and compliance in Irish children and to examine changes in intakes from 2005 to 2019.Design: Analyses were based on data from the Irish National Children's Food Survey (NCFS) and the NSFS II, two cross-sectional studies that collected detailed food and beverage intake data through 7-day and 4-day weighed food diaries, respectively.Setting: NCFS and NCFS II, Republic of Ireland.Participants: A nationally representative sample of 594 (NCFS) and 600 (NCFS II) children aged 5-12 years. Current intakes from the NCFS II were compared with those previously reported in the NCFS (www.iuna.net).Results: Current intakes of total fat, SFA, MUFA, PUFA and trans fat as a percentage of total energy are 33·3, 14·0, 13·6, 5·6 and 0·5 %, respectively. Total fat, SFA and trans fat intakes since 2005 remained largely stable over time with all displaying minor decreases of <1 %. Adherence to SFA recommendations remains inadequate, with only 7 % of the population complying. Insufficient compliance with PUFA (71 %) and EPA and DHA (DHA; 16 %) recommendations was also noted.Conclusion: Children in Ireland continue to meet the total fat and trans fat target goals. Adherence to MUFA and PUFA recommendations has also significantly improved. However, deviations for some fats remain, in particular SFA. These findings are useful for the development of dietary strategies to improve compliance with current recommendations. [ABSTRACT FROM AUTHOR]

The role of meat in the diet has come under scrutiny recently due to an increased public emphasis on providing healthy diets from sustainable food systems and due to health concerns relating to the consumption of red and processed meat. The present review aimed to summarise dietary guidelines relating to meat, actual meat intakes and the contribution of meat to energy and nutrient intakes of children, teenagers and adults in Europe. The available literature has shown that food-based dietary guidelines for most countries recommend consuming lean meat in moderation and many recommend limiting red and processed meat consumption. Mean intakes of total meat in Europe range from 40 to 160 g/d in children and teenagers and from 75 to 233 g/d in adults. Meat contributes to important nutrients such as protein, PUFA, B vitamins, vitamin D and essential minerals such as Fe and Zn; however, processed meat contributes to significant proportions of saturated fat and Na across population groups. While few data are available on diaggregated intakes of red and processed meat, where data are available, mean intakes in adults are higher than the upper limits recommended by the UK Scientific Advisory Committee on Nutrition (70 g/d) and the World Cancer Research Fund (500 g/week). While there are no recommendations for red and processed meat consumption in children and teenagers, intakes currently range from 30 to 76 g/d. The present review provides a comprehensive overview of the role of meat in the European diet which may be of use to stakeholders including researchers, policy makers and the agri-food sector.

Fruit and vegetables (F&V) play an important role in the prevention of obesity and other chronic diseases and low intakes have been highlighted as one of the risk factors attributing to global mortality in adults. The childhood years are a critical period during which eating behaviours and food preferences evolve, providing an opportunity to develop and foster healthy eating practices, which carry into adulthood. This review aimed to summarise dietary guidelines relating to F&V, intakes of F&V and the contribution of F&V to energy and nutrient intakes in school-aged children in Europe. The current review showed a paucity of data in relation to guidelines specific for children for F&V consumption. Where guidelines were available, they ranged from 100 to 500 g or one to three portions of F&V daily (with variations in the categorisations). A key finding was the lack of data on estimates of F&V intakes in school-aged children across Europe. Where data were available, intakes ranged from 221 to 404 g/d and were generally below the WHO recommendation of at least 400 g/d. F&V contributed low proportions of energy intake (6–9%) but made significant contributions to intakes of dietary fibre (19–37%), vitamin A (26–46%), vitamin C (32–83%) and potassium (16–27%); however, they also contributed to intakes of total (25–50%) and free sugar (7–11%). This review has highlighted the need for more data on estimates of F&V intakes in school-aged children in Europe and a need for continued promotion of F&V consumption to increase intakes in this age group.

Objective: The present study aimed to examine the temporal prevalence of overweight and obesity in Irish children through different methodologies and evaluate the change in rates between 1990 and 2019.Design: Anthropometric data from three Irish national food consumption surveys were used to examine the change in the prevalence of BMI and waist circumference-derived overweight and obesity levels.Setting: Three cross-sectional food consumption surveys from the Republic of Ireland: the Irish National Nutrition Survey (1990), the National Children's Food Survey (2005) and The Second National Children's Food Survey (2019).Participants: A demographically representative sample of Irish children aged 5-12 years: 1990 (n 148), 2005 (n 594) and 2019 (n 596).Results: Twelve percentage of children had overweight/obesity in 1990, which was significantly higher in 2005 at 25 % and significantly lower in 2019 at 16 % (P = 0·003). In 2019, more girls had overweight/obesity in comparison with boys (19 v. 14 %), whilst children from the lowest social class group had the highest levels of overweight/obesity (P = 0·019). Overall, the proportion of children with abdominal overweight/obesity was significantly lower in 2019 in comparison with 2005 (P ≤ 0·001).Conclusions: Evidence from the most recent national survey suggests that overweight and obesity levels are plateauing and in some cases reducing in children in Ireland. Despite this, rates remain high, with the highest prevalence in 2019 observed in girls and in those from the lowest social class group. Thus, overweight/obesity prevention and intervention policies are necessary and should be continued. [ABSTRACT FROM AUTHOR]

Objective: To apply a dietary modelling approach to investigate the impact of substituting beef intakes with three types of alternative fatty acid (FA) composition of beef on population dietary fat intakes.Design: Cross-sectional, national food consumption survey - the National Adult Nutrition Survey (NANS). The fat content of the beef-containing food codes (n 52) and recipes (n 99) were updated with FA composition data from beef from animals receiving one of three ruminant dietary interventions: grass-fed (GRASS), grass finished on grass silage and concentrates (GSC) or concentrate-fed (CONC). Mean daily fat intakes, adherence to dietary guidelines and the impact of altering beef FA composition on dietary fat sources were characterised.Setting: Ireland.Participants: Beef consumers (n 1044) aged 18-90 years.Results: Grass-based feeding practices improved dietary intakes of a number of individual FA, wherein myristic acid (C14 : 0) and palmitic acid (C16 : 0) were decreased, with an increase in conjugated linoleic acid (C18 : 2c9,t11) and trans-vaccenic acid (C18 : 1t11; P < 0·05). Improved adherence with dietary recommendations for total fat (98·5 %), SFA (57·4 %) and PUFA (98·8 %) was observed in the grass-fed beef scenario (P < 0·001). Trans-fat intakes were increased significantly in the grass-fed beef scenario (P < 0·001).Conclusions: To the best of our knowledge, the present study is the first to characterise the impact of grass-fed beef consumption at population level. The study suggests that habitual consumption of grass-fed beef may have potential as a public health strategy to improve dietary fat quality. [ABSTRACT FROM AUTHOR]

Purpose: The rate of neural tube defects (NTDs) in Europe has remained similar since the 1990s despite folic acid supplement recommendations (400 µg/day) for women of childbearing age. Mandatory folic acid fortification of staple foods has proved effective for reducing the prevalence of NTDs in over 80 countries. This study estimated the impact of addition of folic acid to bread or flour in the Republic of Ireland on reducing the risk of occurrence of NTD-affected pregnancies and the possible risk of masking (undiagnosed) vitamin B12 deficiency in older adults. Methods: Analyses were based on the Irish National Adult Nutrition Survey (2008–2010). Folic acid fortification was modelled using DaDiet© software. Estimates were made of the increase in average daily folic acid intake in women (18–50 years) and the risk of exceeding the tolerable upper intake level (UL) of 1000 µg for folic acid in adults over 50 years of age. Results: The fortification scenarios examined would reduce the risk of NTD-affected pregnancies by 8–32%, corresponding to an increase of 39–152 μg in the mean daily folic acid intake of WCBA. The risk of masking anaemia associated with vitamin B12 deficiency in older adults would be negligible as the probability of exceeding the UL for folic acid, even by a small amount, is very low (≤ 0.2%). Conclusions: These levels of addition of folic acid to bread or flour would effectively reduce the risk of NTDs while allowing safe consumption of folic acid at current levels from other fortified foods and supplements.
