Ultra-processed foods (UPF) and minimally processed foods (MPF) consumption are differentially connected to adiposity and possibly body composition. Phase angle (PhA) originates from bioelectrical impedance analysis (BIA) and is connected to cellular health. This study is the first to investigate associations between UPF/MPF consumption and PhA.

A cross-sectional study was conducted. Anthropometrical and BIA were performed. The Hellenic Physical Activity Questionnaire was used for physical activity evaluation, while a validated FFQ was used for dietary assessment. UPF and MPF intake (% energy) were determined according to the NOVA system. Partial correlation coefficients of PhA and dietary variables were assessed after multi-adjustment.

Students were recruited (n 151, 114 women).

University

Median and interquartile range (IQR) of PhA were 5·5° (5·1–6·4°) in the total sample, 6·8° (6·1–7·3°) in men and 5·3° (5·1–5·9°) in women (P < 0·001). The median and IQR for UPF consumption was 13·7 (8·1–33·4) % in the total sample, 23·8 (8·1–70·5) % in men and 12·9 (8·1–27·5) % in women (P < 0·001). The mean (sd) of MPF consumption was 60·2 (sd 15·7) % for the total sample, 59·1 (sd 16·4) % for men and 60·5 (sd 15·6) % for women (P = 0·720). The consumption of UPF was negatively (rho = –0·267, P = 0·002), while the consumption of MPF was positively (rho = 0·218, P = 0·010) associated with the PhA, after adjustment for age, sex, BMI and physical activity.

PhA relates inversely to UPF and positively to MPF consumption. The observed associations possibly reflect the effects of diet on cellular health and in turn PhA.

To describe the prevalence of food poverty according to dimensions of socio-economic inequality and the food groups consumed by Brazilian children.

Dietary data from a structured qualitative questionnaire collected by the Brazilian National Survey on Child Nutrition (ENANI-2019) were used. The new UNICEF indicator classified children who consumed 3–4 and <3 out of the eight food groups as living in moderate and severe food poverty, respectively. The prevalence of consumption of each food group and ultra-processed foods (UPF) was estimated by level of food poverty according to age categories (6–23; 24–59 months). The most frequent combinations of food groups consumed by children living in severe food poverty were calculated. Prevalence of levels of food poverty were explored according to socio-economic variables.

123 municipalities of the five Brazilian macro-regions.

12 582 children aged 6–59 months.

The prevalence of moderate and severe food poverty was 32·5 % (95 % CI 30·1, 34·9) and 6·0 % (95 % CI 5·0, 6·9), respectively. Children whose mother/caregiver had lower education (<8 years) and income levels (per capita minimum wage <¼) had the highest severe food poverty prevalence of 8·3 % (95 % CI 6·2, 10·4) and 7·5 % (95 % CI 5·6, 9·4), respectively. The most consumed food groups among children living in food poverty in all age categories were ‘dairy products’, ‘grains, roots, tubers, and plantains’ and ‘ultra-processed foods’.

Food poverty prevalence was high among Brazilian children. A significant occurrence of milk consumption associated with grains and a considerable prevalence of UPF consumption were found among those living in severe food poverty.

The objective of study was to assess 24-h urinary Na and K excretion and estimate the average salt and K intakes in a nationally representative sample of the adult population of Slovenia.

A nationally representative cross-sectional study was conducted in four stages between September and November 2022: study questionnaire, physical measurements, 24-h urine collection and laboratory analysis.

Slovenia.

We invited 2000 adult, non-institutionalised inhabitants of Slovenia, aged between 25 and 64 years. A stratified two-staged sample was selected from this population by the Statistical Office of Slovenia, using sampling from the Central Population Register. According to the WHO methodology, additional eligibility criteria were screened before participating. A total of 518 individuals participated in all four stages of the study, resulting in a response rate of 30 %.

The mean 24-h urinary Na excretion was 168 mmol/d (95 % CI 156, 180), which corresponds to a mean estimated intake of 10·3 g salt/d (95 % CI 9·6, 11·1). Mean 24-h urinary K excretion was 65·4 mmol/d (95 % CI 63·2, 67·5), and the estimated mean K intake was 2·93 g/d (95 % CI 2·84, 3·03). There were statistically significant differences in mean intakes between males and females. The mean sodium-to-potassium ratio was 2·7 (95 % CI 2·5, 2·8).

The study results highlighted that the salt intake in the adult population of Slovenia remains much higher than recommended by the WHO, and K intakes are insufficient, as most participants did not meet the recommendations.

The purpose of this study was to examine the dissemination of the healthy eating component of Appetite to Play at scale using the Reach, Effectiveness, Adoption, Implementation, Maintenance (RE-AIM) framework.

The Appetite to Play capacity-building intervention is a set of evidence-informed implementation strategies aimed at enhancing the adoption of recommended practices for promoting healthy eating and active play in early years settings. The evaluation was pragmatic, employing both quantitative (surveys) and qualitative (interviews) data collection.

The Appetite to Play intervention was delivered through in-person community-based workshops, virtual workshops, asynchronous e-learning and online resources.

We received completed surveys from 1670 in-person workshop participants (96 % female), and twenty-three (all female) survey respondents also participated in a telephone interview. Approximately two-thirds of all participant groups were certified early childhood educators.

Results indicated that Appetite to Play had high reach (25 867 individual website visits, 195 workshops delivered), effectiveness (significant increases in care provider’s knowledge, confidence (P < 0·05) and high post-intervention intention to implement), adoption (11 % of educators in BC trained) and implementation (good alignment with implementation strategies and current practices), with a significant maintenance plan to support the intervention’s future success.

An evidence-based capacity-building intervention with an emphasis on training and provision of practical online resources can improve early years providers’ knowledge, confidence and intention to implement recommended practices that promote healthy eating. Further research is needed to determine the impact on child-level outcomes and how parents can be supported in contributing to positive food environments.

To investigate the causal link between the North American Free Trade Agreement (NAFTA) unrestricted sugar trade agreement signed in 2008 between the USA and Mexico and the diabetes prevalence across all fifty US states.

A quasi-experimental research design to investigate the causal effect of the NAFTA unrestricted sugar trade agreement on diabetes prevalence. Our study utilises a comprehensive panel dataset spanning from 2000 to 2016, comprising 1054 observations. To conduct our analysis, we applied both the difference-in-differences and event-study methodologies.

All the states in the USA.

The fifty states in the USA.

After the enactment of the NAFTA sugar trade agreement between the USA and Mexico in 2008, most states witnessed an increase in diabetes prevalence. The annual impacts displayed significant variation among states, with percentage increases spanning from 0·50 to 2·28 %.

States with a higher percentage of their population living below the poverty line, a larger Black resident population and a lower proportion of high school graduates had more significant increases in diabetes prevalence attributed to the NAFTA sugar trade agreement.

The solicitation of nutrition-related health advice on social media platforms is on the rise. However, there is a paucity of research on the distinctive nutrition-related concerns and needs faced by transgender and gender-diverse individuals. Understanding patterns of nutrition-related information-seeking behaviour is vital to advancing health promotion efforts within this community. This study aimed to characterise the nutrition-related questions posed by the transgender community on a prominent social media outlet, Reddit.

A qualitative, cross-sectional content analysis was conducted, focusing on the top 100 submissions (ranked by popularity) within a transgender-centric online subreddit (r/asktransgender). Data extraction was facilitated using the Application Programming Interface Pushshift. The content analysis was conducted using NVivo.

The study was situated within the discussion forum of the social media platform, Reddit.

A total of 148 references from 90 eligible posts were identified and coded. The major themes included the effects of hormone replacement therapy (HRT) on nutritional health (n 66), weight status (n 45), dietary needs and behaviours (n 21), physical activity and weight loss on body shape (n 9), social undermining (n 4) and effects of health behaviours on HRT (n 3).

This study underscores the pressing need for tailored and evidence-based nutrition guidelines and communication toolkits that specifically address the distinct needs and experiences of transgender individuals, particularly those undergoing HRT.

Prior research has shown that there are more supermarket displays of sugar-sweetened beverages (SSB) during times when Supplemental Nutrition Assistance Program (SNAP) benefits are distributed (‘issuance periods’). This may contribute to inequitable purchasing and consumption. This study examines whether SSB marketing in weekly supermarket circulars, which retailers use to advertise products, is more prevalent during issuance periods compared to non-issuance periods.

We conducted longitudinal, difference-in-differences analyses of data extracted from weekly supermarket circulars of randomly selected SNAP-authorised retailers in six states. Analyses tested whether SSB advertisements (‘ads’) were more prevalent during SNAP issuance periods compared to non-issuance periods within states with distinct issuance periods (3, 5, 10 or 15 d), compared to one state with continuous benefit issuance (28 d; the ‘control’ state).

Weekly online supermarket circulars collected from August to September 2019 were analysed in 2021.

The study sample included 5152 circulars from 563 SNAP-authorised retailers in the states California, Connecticut, Nebraska, New Jersey and Texas (distinct issuance period states) as well as Florida (‘control’ state).

The estimated mean percentage of beverage ads classified as SSB ads during issuance days was 51·5 % compared to 48·4 % during non-issuance days (P < 0·001). In difference-in-differences analyses comparing to the ‘control’ state with continuous issuance, SSB ad counts were 2·9 % higher (95 % CI 1·9 %, 3·9 %) during SNAP issuance relative to non-issuance.

SSB ads are slightly more prevalent in weekly supermarket circulars during SNAP issuance periods. Future research should explore the linkages between circular ads and SSB purchasing and consumption.

To assess the relationship between dietary intake of α-carotene, β-carotene, β-cryptoxanthin, lycopene and lutein+zeaxanthin (LZ) and occurrence of metabolic dysfunction-associated fatty liver disease (MAFLD).

Cross-sectional study design. The MAFLD diagnosis was based on hepatic steatosis and metabolic dysregulation. Carotenoid intake was adjusted for using an energy-adjusted model. Logistic regression and restricted cubic spline (RCS) analyses were used to assess the relationships, with sensitivity analysis to validate the findings. Weighted quantile sum regression (WQS) was used to explore the combined effect of these carotenoids on MAFLD. Subgroup analyses were conducted to identify population-specific associations.

National Health and Nutrition Examination Survey (NHANES) 2017–March 2020.

This study included 5098 individuals aged 18 years and older.

After adjusting for potential confounders, a weak inverse association was observed between α-carotene and β-carotene intakes and MAFLD occurrence (all P value <0·05). The highest quartile of β-carotene intake showed a significantly lower occurrence of MAFLD compared with the lowest quartile (OR = 0·65; 95 % CI: 0·44, 0·97). RCS analysis showed that a significantly lower occurrence of MAFLD was associated with a higher intake of the four carotenoids, excluding lycopene. Furthermore, the WQS analysis revealed a negative relationship between combined carotenoid intake and MAFLD occurrence (OR = 0·95, 95 % CI: 0·90, 1·00, P = 0·037). Subgroup analyses showed dietary carotenoid intake was associated with reduced MAFLD occurrence in populations aged 50–69 years, females, physically active individuals and non-drinkers.

Higher dietary intake of carotenoids is associated with lower MAFLD occurrence. However, this relationship varies among individuals of different ages, sexes and lifestyles.

To investigate how dieting is portrayed on TikTok and the potential implications for public health considering the effect of diet culture on eating disorders amongst young people.

A cross-sectional descriptive content analysis of 250 videos from the five most popular diet-related hashtags. A codebook was developed to analyse the content of the videos and collect the engagement for each video (likes, comments and shares).

TikTok website.

There were no participants in this study.

More than half of the videos portrayed ‘body checking’, a potentially harmful practice for body image. Of the videos that represented body image, almost half represented body image negatively. However, most videos promoted the idea of ‘healthy eating’, and only 6·4 % displayed disordered eating behaviours. Over half of the videos provided dietary advice, and of those videos, most content creators claimed to be experts (64 %). Claiming expertise was not significantly associated with engagement; however, the use of humour was significantly associated with engagement. Additionally, males were more likely than females to disclose their goals of the diet.

Overall, it appears that TikTok is commonly used to share nutrition tips and personal experiences around dieting and eating in general, often employing humour as an effective technique. The popularity of the platform and rapid dissemination of information would be a useful tool for health professionals, especially those working with eating disorders, to utilise.

This scoping review aimed to systematically map and describe the existing evidence regarding the knowledge, attitudes and practices of health professionals with regard to plant-based diets during pregnancy and to highlight areas for further research.

Following a pre-registered protocol, online databases were searched using a comprehensive search string, in addition to selected grey literature sources, and reference lists of included studies. The studies were independently screened for eligibility by two authors, SM and JM. Data from all eligible studies were charted by the first author, and a narrative summary was performed.

Maternal health care services.

Ten studies were included for review, from New Zealand (n 2), Australia (n 2), Germany, Netherlands, United Kingdom, France, Italy and Peru. Most of these studies were observational, employed various validated and non-validated survey instruments, interviews and one education intervention. Knowledge was the most frequently assessed outcome in the reviewed studies. Health professionals’ knowledge of plant-based nutrition in pregnancy was reported to be limited and frequently attributed to a lack of nutrition training. Participants’ personal dietary patterns and work specialisation appear to be closely associated with their knowledge, attitudes and practices regarding plant-based diets.

This review identified a significant research gap regarding health professionals’ practices in relation to plant-based diets during pregnancy. Additionally, this review has demonstrated the need for further research, awareness and practice protocols to promote high-quality care and education or professional development to address the prevalent lack of knowledge among this group.

Food literacy (FL) is a potential approach to address the nutrition transition in Africa, but a validated tool is lacking. We developed and validated a scale to assess FL among Ugandan and Kenyan adult populations.

A mixed-method approach was applied: (1) item development using literature, expert and target group insights, (2) independent country-specific validation (content, construct, criterion and concurrent) and (3) synchronisation of the two country-specific FL-scales. Construct validity was evaluated against the prime dietary quality score (PDQS) and healthy eating self-efficacy scale (HEWSE).

Urban Uganda and Kenya.

Two cross-sectional cross-country surveys, adults >18 years (n = 214) and university students (n = 163), were conducted.

The initial development yielded a forty-eight-item FL-scale draft. In total, twenty-six items were reframed to fit the country contexts. Six items differed content-wise across the two FL-scales and were dropped for a synchronised East African FL-scale. Weighted kappa tests revealed no deviations in individuals’ FL when either the East African FL-scale or the country-specific FL-scales are used; 0·86 (95 % CI: 0·83, 0·89), Uganda and 0·86 (95 % CI: 0·84, 0·88), Kenya. The FL-scale showed good reliability (0·71 (95 % CI: 0·60, 0·79), Uganda; 0·78 (95 % CI: 0·69, 0·84), Kenya) and positively correlated with PDQS (r = 0·29 P = 0·003, Uganda; r = 0·26 P < 0·001, Kenya) and HEWSE (r = 0·32 P < 0·001, Uganda; r = 0·23, P = 0·017, Kenya). The FL-scale distinguishes populations with higher from those with lower FL (β = 14·54 (95 % CI: 10·27, 18·81), Uganda; β = 18·79 (95 % CI: 13·92, 23·68), Kenya).

Provided culture-sensitive translation and adaptation are done, the scale may be used as a basis across East Africa.

The International Code of Marketing of Breast-Milk Substitutes is an important instrument to protect and promote appropriate infant and young child feeding and the safe use of commercial milk formulas. Ghana and Tanzania implemented the Code into national legislation in 2000 and 1994, respectively. We aimed to estimate the effects of the Code implementation on child mortality (CM) in both countries.

The countries analysed were Ghana and Tanzania.

For CM and HIV rates, data from the Institute for Health Metrics and Evaluation from up to 2019 were used. Data for income and skilled birth rates were retrieved from the World Bank, for fertility from the World Population Prospects, for vaccination from the Global Health Observatory and for employment from the International Labour Organization.

We used the synthetic control group method and performed placebo tests to assess statistical inference. The primary outcomes were CM by lower respiratory infections, mainly pneumonia, and diarrhoea and the secondary outcome was overall CM.

One-sided inference tests showed statistically significant treatment effects for child deaths by lower respiratory infections in Ghana (P = 0·0476) and Tanzania (P = 0·0476) and for diarrhoea in Tanzania (P = 0·0476). More restrictive two-sided inference tests showed a statistically significant treatment effect for child deaths by lower respiratory infections in Ghana (P = 0·0476). No statistically significant results were found for overall CM.

The results suggest that the implementation of the Code in both countries had a potentially beneficial effect on CM due to infectious diseases; however, further research is needed to corroborate these findings.

To identify (1) who experiences food insecurity of differing severity and (2) who uses food banks in England, Wales and Northern Ireland; (3) whether the same groups experience food insecurity and use food banks; and (4) to explore country- and region-level differences in food insecurity and food bank use.

This pooled cross-sectional study analysed the characteristics of adults experiencing food insecurity of differing severity using generalised ordinal logistic regression models and the characteristics of adults using food banks using logistic regression models, using data from three waves of the Food and You 2 surveys, 2021–2023.

England, Wales and Northern Ireland.

18 557 adults.

20·8 % of respondents experienced food insecurity in the past 12 months, and 3·6 % had used a food bank. Food insecurity was associated with income, working status, respondent age, family type, ethnicity, country, long-term health conditions, food hypersensitivity, urban-rural status and area-level deprivation. Severe food insecurity was concentrated among respondents with long-term health conditions and food hypersensitivities. Food bank use was more prevalent among food insecure respondents and unemployed and low-income respondents. Neither outcome showed clear geographical variation. Certain groups experienced an elevated likelihood of food insecurity but did not report correspondingly greater food bank use.

Food insecurity is unevenly distributed, and its nutrition and health-related consequences demonstrate that food insecurity will intensify health inequalities. The divergence between the scale of food insecurity and food bank use strengthens calls for adequate policy responses.

Schools are identified as a setting for food and nutrition education (FNE) in childhood. FNE is a key strategy to optimise child growth and development and impart life-long food skills. There is limited synthesis of the literature to understand the socio-ecological determinants of teachers and schools engaging in FNE.

For this scoping review, five databases (APA PsycInfo, ERIC, Medline, CINAHL and Scopus) were searched using the terms (and synonyms for) primary school teacher, self-efficacy and food and nutrition. A quality assessment using relevant Johanna Briggs tools was carried out for the included papers. Data were extracted using a modified socio-ecological model, and narrative themes were identified.

Primary (elementary) schools in high-income countries.

Primary-school teachers.

Forty-one papers were included in this review from ten countries (predominantly the USA). The narrative synthesis identified five themes that interact with teacher delivery of FNE. These were (i) perceived food and nutrition responsibilities of teachers, (ii) teacher beliefs and self-efficacy, (iii) opportunities to build teacher nutrition knowledge and self-efficacy, (iv) interpersonal contributors and (v) broader environmental, structural and policy contributors.

Multiple strategies are needed to build the capacity of teachers to undertake FNE within primary school settings. These strategies include a focus on learner-centred education that will build teacher agency, school leadership, ensuring the health and well-being of teachers and providing initial teacher education as well as innovative professional development for cross-curriculum integration. Strategies drawing from each level of the socio-ecological framework will increase opportunities for capacity building.

Numerous studies have examined the relationship between overweight/obesity and iron deficiency anaemia (IDA) across diverse population groups, but a definitive link has not been clearly determined. This systematic review examined the association between overweight/obesity and IDA in women of reproductive age (WRA).

The initial search was performed in the CINAHL, Embase, MEDLINE, SCOPUS and Web of Science databases. The studies included should report at least one Fe status with/without an inflammatory marker, using the BMI to define overweight/obesity. Only baseline data were extracted for longitudinal studies.

Global.

Pregnant or non-pregnant women aged 18–50 years.

In total, twenty-seven papers were included (twelve addressing pregnant women and fifteen addressing non-pregnant women). Overall, most of the studies reported no association between overweight/obesity and Hb concentration. However, a positive association was reported more frequently in pregnant women. The association between overweight/obesity and serum ferritin concentrations was mixed. Most of the studies on non-pregnant women reported a positive association. Only a few studies measured hepcidin and inflammatory markers, and the majority revealed an increased level among overweight/obese WRA. Among pregnant women, overweight/obesity was positively associated with anaemia and IDA but negatively associated with iron deficiency (ID). Meanwhile, overweight/obese non-pregnant women were positively associated with anaemia, ID and IDA.

Overweight/obesity was associated with a decreased prevalence of anaemia and IDA but an increased prevalence of ID, while its association with several Fe markers was inconclusive. Further studies integrating the assessment of various Fe markers, inflammatory markers and hepcidin are needed.

Water is an essential nutrient for all organisms and is important for maintaining life and health. We aimed to develop a biomarker-calibrated equation for predicting water turnover (WT) and pre-formed water (PW) using the doubly labelled water (DLW) method.

Cross-sectional study.

General older population from the Kyoto–Kameoka Study, Japan.

The 141 participants aged ≥ 65 years were divided into a model developing (n 71) and a validation cohort group (n 70) using a random number generation. WT and PW was measured using the DLW method in May–June of 2012. In developing the cohort, equations for predicting WT and PW were developed by multivariate stepwise regression using all data from the questionnaires in the Kyoto–Kameoka study (including factors such as dietary intake and personal characteristics). WT and PW measured using the DLW method were compared with the estimates from the regression equations developed using the Wilcoxon signed-rank test and correlation analysis in validation cohort.

The median WT and PW for 141 participants were 2·81 and 2·28 l/d, respectively. In the multivariate model, WT (R2 = 0·652) and PW (R2 = 0·623) were moderately predicted using variables, such as height, weight and fluid intake from beverages based on questionnaire data. WT (r = 0·527) and PW (r = 0·477) predicted that using this model was positively correlated with the values measured by the DLW method.

Our results showed factors associated with water requirement and indicated a methodological approach of calibrating the self-reported dietary intake data using biomarkers of water consumption.

To estimate how incentives that encourage healthy eating among Supplemental Nutrition Assistance Program (SNAP) participants impact intra-monthly variation in fruit and vegetable spending.

We used transaction data from three Alabama grocery stores participating in a programme that offered dollar-matching coupons for fresh produce. For each store, we calculated daily spending on fresh produce out of SNAP benefits and daily incentive coupon redemptions. We compared total daily spending on fresh produce and daily coupon redemptions on days over which SNAP benefits are distributed in Alabama with spending and redemption on days at the end of the month with no SNAP distribution.

SNAP and incentive transactions in three Alabama grocery stores.

SNAP participants purchasing fruit and vegetables April 2023–July 2023.

Daily spending with SNAP on produce dropped by 38% at the end of the month. Incentive coupon redemption did not significantly drop at the end of the month. The share of total SNAP spending going to fresh fruits and vegetables increased by two percentage points and the share of fresh fruits and vegetables spending coming from redemptions increased by ten percentage points at the end of the month.

SNAP households may use incentive coupons to smooth drops in produce consumption at the end of the month. These findings also highlight trade-offs inherent in different delivery mechanisms for SNAP incentives.

To assess the impact of nutritional and multiple-micronutrient supplementation to lactating mothers on the micronutrient status of mother–infant dyad at 6 months of age postnatally.

This study was a trial that aimed to investigate the impact of maternal nutritional supplementation on infant growth. A secondary objective was to assess the effect on the micronutrient status of mother–infant pairs. The intervention group mothers received snacks with 600 kcal energy, 20 g protein and daily micronutrient tablets.

Blood samples were collected from both mothers and infants at 6 months.

The participants in this study were mother–infant pairs. The micronutrient status of these pairs was assessed through blood samples, focusing on vitamins A, D, B12, ferritin, Zn and folate.

Micronutrient analysis of serum samples from 600 mother–infant pairs showed that mothers in the intervention group had higher levels of serum ferritin (mean difference (MD) 14·7 ng/ml), retinol (MD 0·6 μmol/l), folate (MD 3·3 ng/ml) and vitamin D (1·03 ng/ml) at 6 months postpartum. Additionally, the supplementation was associated with a higher mean ± sd of serum ferritin (MD 8·9 ng/ml) and vitamin A (MD 0·2 μmol/l) levels in infants at 6 months.

The study found that supplementing maternal nutrition with additional dietary and micronutrient intakes during lactation improved maternal micronutrient status and slightly increased ferritin and vitamin A levels in infants at 6 months. The findings highlight the importance of nutritional interventions for improving the micronutrient health of mother–infant pairs, with significant public health implications.

To characterise consumption of ultra-processed foods and drinks (UPF) across a range of socio-demographic characteristics of Canadians.

Cross-sectional study. The national-level 2015 Canadian Community Health Survey–Nutrition provided data on all foods and drinks consumed on the previous day via a 24-hour dietary recall. All food items were classified according to the type of industrial processing using the NOVA system. Multivariable linear regression models examined associations between a range of socio-demographic characteristics and the mean energy contribution (% of total daily energy intake) from total UPF and UPF subgroups.

The ten Canadian provinces.

Canadians aged 2 or older (n 20 103).

UPF contributed, on average, nearly half (44·9 %) of total daily energy intake of Canadians. Children aged 6–12 and adolescents aged 13–18 consumed over half of total daily energy from UPF (adjusted means of 51·9 % and 50·7 %, respectively). Recent and long-term immigrants consumed a significantly lower share of energy from UPF (adjusted means of 42·2 % and 45·1 %, respectively) compared with non-immigrants (54·4 %), as did the food secure (42·8 %) v. those in moderately (48·1 %) or severely food-insecure households (50·8 %). More modest differences were observed for intake of total UPF and UPF subgroups by sex, education, income adequacy and region of residence.

Levels of UPF consumption in 2015 in Canada were pervasive in all socio-demographic groups and highest among children and adolescents, non-immigrants and those living in food-insecure households. These findings can inform public health interventions to reduce UPF consumption and promote healthier diets in various socio-demographic groups.
