To explore the association between dietary Na intake and non-alcoholic fatty liver disease (NAFLD) in a nationally representative sample of the US population.

In this cross-sectional study, the associations between Na intake and NAFLD, defined by the hepatic steatosis index (HSI) and the fatty liver index (FLI), were assessed through multivariable logistic regression models.

Communities in the USA from 2007 to 2014.

Men and women aged 20 years and older.

A total of 11 022 participants were included in the HSI-defined NAFLD analysis, and a subsample of 5320 participants was included in the FLI-defined NAFLD analysis. Compared with the lowest quartile of Na intake, the highest quartile had a multivariate-adjusted OR and 95 % CI of 1·46 (1·29, 1·65) for NAFLD as defined by HSI, and 1·41 (1·18, 1·69) for NAFLD as defined by FLI. This association was, to some degree, attenuated but remained significant after adjusting for several related metabolic parameters, including BMI, hypertension, hypercholesterolaemia, and diabetes.

Findings from the current study indicate that dietary Na intake is positively associated with NAFLD in US adults.

In low- and middle-income countries, undernutrition remains a major risk factor for child growth retardation. In addition, the emergence of obesity in recent years is adding another public health concern in that both stunting and obesity are associated with serious adverse health consequences. This review was designed to evaluate the prevalence of stunting and obesity in Ecuador.

Electronic databases were searched for articles published through February 2018 reporting the prevalence of stunting and/or obesity. Selected data were subjected to meta-analysis and pooled prevalence and their 95 percentiles (95 % CI) were calculated.

Studies were identified in Medline, Web of Science, CINAHL, Cochrane Database and Ibero-America databases.

Population of Ecuador.

Twenty-three articles were selected according to the inclusion/exclusion criteria of the study. The estimate of pooled prevalence of stunting was 23·2 % (95 % CI 23·3, 23·5) in preschoolers (age < 5 years), but was markedly higher in indigenous and rural communities. Pooled prevalence of obesity was 8·1 % (95 % CI 6·9, 9·3), 10·7 % (95 % CI 9·6, 11·7) and 10·5 % (95 % CI 9·2, 11·8) in preschoolers, school-age children (age: 5–11 years) and adolescent (age: 12–18 years), respectively. In adults (age ≥ 19 years), the rate of obesity was remarkably high as indicated by an overall estimate equal to 44·2 % (95 % CI 43·1, 45·4).

This study underlines high levels of stunting among children and obesity among adults in Ecuador, both of which are not equally distributed among the population. The magnitude of this double burden emphasises the need for sustained and targeted interventions.

To assess the contribution of different food groups to total salt purchases and to evaluate the estimated reduction in salt purchases if mandatory maximum salt limits in South African legislation were being complied with.

This study conducted a cross-sectional analysis of purchasing data from Discovery Vitality members. Data were linked to the South African FoodSwitch database to determine the salt content of each food product purchased. Food category and total annual salt purchases were determined by summing salt content (kg) per each unit purchased across a whole year. Reductions in annual salt purchases were estimated by applying legislated maximum limits to product salt content.

South Africa.

The study utilised purchasing data from 344 161 households, members of Discovery Vitality, collected for a whole year between January and December 2018.

Vitality members purchased R12·8 billion worth of food products in 2018, representing 9562 products from which 264 583 kg of salt was purchased. The main contributors to salt purchases were bread and bakery products (23·3 %); meat and meat products (19 %); dairy (12·2 %); sauces, dressings, spreads and dips (11·8 %); and convenience foods (8·7 %). The projected total quantity of salt that would be purchased after implementation of the salt legislation was 250 346 kg, a reduction of 5·4 % from 2018 levels.

A projected reduction in salt purchases of 5·4 % from 2018 levels suggests that meeting the mandatory maximum salt limits in South Africa will make a meaningful contribution to reducing salt purchases.

To conduct a systematic review of studies for the validation of semiquantitative FFQ (SFFQ) that assess food intake in adults.

The authors conducted a systematic search in PubMed for articles published as late as January 2020 in Spanish, English, French and Portuguese. Individual searches (twelve in total) paired three hyphenated and non-hyphenated variations of ‘semiquantitative food frequency questionnaire’ with both ‘validity’ and ‘validation’ using the ‘all fields’ and the ‘title/abstract’ retrieval categories. Independent extraction of articles was performed by four authors using predefined data fields.

We searched for original SFFQ validation studies that analysed general diet composition (nutrients with or without food groups or energy analysis) in healthy adults, in any setting, and that also reported correlation coefficients.

Healthy adults.

Sixty articles were included. The preferred comparison standard for validation was food records (n 37). The main correlation coefficients used were Pearson’s (n 41), and validity coefficients varied from −0·45 to 1. Most correlation coefficients were adjusted by energy (twelve studies presented only crude values). The elements mentioned most frequently were energy, macronutrients, cholesterol, SFA, PUFA, fibre, vitamin C, Ca and Fe.

Although all these SFFQ are reported as validated, coefficients may vary across groups of foods and nutrients. Based on our findings, we suggest researchers to consult our revision before choosing a SFFQ and to review important issues about them, such as their validation, number of items, number of participants, etc. Systematic Review Registration: PROSPERO number CRD42017064716.

Developing health promotion activities, aimed at healthy food intake, is essential for improving quality of life and reducing the prevalence of chronic diseases. Thus, the objective of this study is to describe both dietary and nutrient intake, according to length of participation in a health promotion service (Programa Academia da Saúde – PAS).

A cross-sectional study was carried out with a representative sample of PAS units in vulnerable areas of the city. Dietary and nutrient intake were assessed, using the average of two 24-h recalls. Food was categorised according to the NOVA (a systematic grouping of all foods according to the nature, extent and purpose of the industrial processes they undergo) classification. The length of participation in PAS is presented in months and is then examined in tertiles for analysis.

Belo Horizonte – Brazil.

3372 adults (≥20 years).

Users in the third tertile of PAS (24·4–61·6 months) experienced less energy intake, lipids and ultra-processed foods, and more culinary preparations, compared to others. Users in the second (10·1–24·3 months) and third tertiles of PAS had higher carbohydrate intake, Ca and vitamin C v those in the first tertile (0–10 months).

Results suggest that greater participation in PAS can improve dietary and nutrient intake, showing its potential to promote healthy lifestyles, prevent chronic diseases and offer longitudinal health care.

To assess the association between pregestational BMI and offspring’s risk of overweight/obesity after accounting for the most important confounders, especially maternal smoking habit.

Prospective cohort study.

The Seguimiento Universidad de Navarra (SUN) study is a prospective cohort of Spanish graduates with more than 22 000 participants nationwide. Recruitment started in 1999, and it is permanently open. Data on diet, lifestyle and clinical diagnoses are collected at baseline and every 2 years.

Women from the SUN cohort who reported at least one pregnancy during follow-up (n 3496) were invited to this study. Among them, 1527 agreed to participate and completed an additional more detailed online questionnaire on their pregnancy history and their offspring’s nutritional status.

After excluding 165 children, we analysed data of 2791 participants born to 1485 mothers and observed that each 5 kg/m2 increase in pregestational BMI was associated with a 0·22 (95 % CI 0·15, 0·29) higher z-score in offspring’s BMI and higher risk of overweight/obesity (multivariable-adjusted relative risk (RR) 1·57 (95 % CI 1·39, 1·77)) in childhood or adolescence. Furthermore, we observed stronger association in children born to smoker mothers (RR 1·91; 95 % CI 1·48, 2·46) than from non-smoker mothers (RR 1·51; 95 % CI 1·31, 1·73) (Pfor interaction = 0·02).

We found a synergistic interaction between pregestational BMI and maternal smoking habit on offspring’s z-score of the BMI and in their risk of overweight/obesity. Although further research is needed to analyse dose–response relationships, these findings reinforce the importance of promoting healthy lifestyles in pregnant women in order to prevent childhood obesity.

To measure the role of water, sanitation and hygiene (WASH) practices on recovery from stunting and assess the role of timing of stunting on the reversal of this phenomenon

Data from the MAL-ED multi-country birth cohort study was used for the current analysis. Generalised linear mixed-effects models were used to estimate the probability of reversal of stunting with WASH practice and timing of stunting as the exposures of interest.

Seven different countries across three continents.

A total of 612 children <2 years of age.

We found that not WASH practice but timing of stunting had statistically significant association with recovery from stunting. In comparison with the children who were stunted at 6 months, children who were stunted at 12 months had 1·9 times (β = 0·63, P = 0·03) more chance of recovery at 24 months of age. And, children who were stunted at 18 months of age even had higher odds (adjusted OR = 3·01, β = 1·10, P < 0·001) of recovery than children who were stunted at 6 months. Additionally, mother’s height (β = 0·59, P = 0·04) and household income (β = 0·02, P < 0·05) showed statistically significant associations with the outcome.

The study provided evidence for the role of timing of stunting on the recovery from the phenomenon. This novel finding indicates that the programmes to promote linear growth should be directed at the earliest possible timepoints in the course of life.

To examine the association between household food insecurity and overweight, obesity and abdominal obesity in Mexican adults.

Cross-sectional study.

We analysed data from the Mexican Halfway National Health and Nutrition Survey 2016, a nationally representative survey that accounted for rural and urban areas in four regions of Mexico: North, Centre, Mexico City and South.

Adults from 20 to 59 years old (n 5456, which represents 45 804 210 individuals at the national level).

70·8 % of the Mexican adults had some degree of household food insecurity. This situation showed larger proportions (P < 0·05) among indigenous people, those living in a rural area, in the Southern region or the lowest socio-economic quintiles. The prevalence of obesity and abdominal obesity was higher in female adults (P < 0·001), with the highest proportions occurring among those experiencing severe household food insecurity. Among women, mean BMI and waist circumference were higher as household food insecurity levels increased (P < 0·001). According to multivariate logistic regression models, severe household food insecurity showed to be positively associated with obesity (OR: 2·36; P = 0·001) in Mexican adult females.

Our findings confirm the association between household food insecurity and obesity among Mexican women. Given the socio-demographic characteristics of the food-insecure population, it is alarming that prevailing socio-economic inequalities in the country might also be contributing to the likelihood of obesity. Therefore, it is crucial to maintain and bolster surveillance systems to track both problems and implement adequate policies and interventions.

To evaluate the impact of changes in import tariffs on sweetened beverages.

Interrupted time series analysis was used to examine sweetened beverage tariff increases of 40–60 % in 2008 and to 75 % in 2012, and an approximately 11 % decrease in 2014 when an excise tax replaced the tariff. Post-tax trends were compared with a counterfactual modelled on the pre-tax trend for: quarterly price of an indicator beverage, monthly beverage import volumes (both 2001–2017) and quarterly sales volumes (2012–2017). In a controlled analysis, taxed beverage imports were compared with a sugary snacks control.

Cook Islands.

NA.

In the first year, after the 2008 tariff increase the price of the selected indicator soft drink increased by 7·3 % (95 % CI 6·3 %, 8·3 %) but after the 2012 tariff increase it decreased by 13·9 % (95 % CI –14·9 %, –12·8 %). At the same time, the import volumes of taxed beverages decreased by 13·2 % (95 % CI –38·1 %, 17·8 %) and 2·9 % (95 % CI –41·6 %, 72·5 %), respectively, and decreased by 24·8 % (95 % CI –36·9, –9·8) and 10·2 % (95 % CI –37·1, 37·5) in the controlled analysis. After the 2014 tax decrease, the price of the indicator soft drink decreased by 23·6 % (95 % CI –26·0 %, –21·1 %), sweetened beverage imports increased by 4·5 % (95 % CI –39·5 %, 156·0 %) and sales of full-sugar soft drinks increased by 31 % (95 % CI –21 %, 243 %).

The increased import tariffs on sweetened beverages appeared to be effective for reducing import volumes, but this was partly reversed by the reduced tax/tariff in 2014.

Dietary pattern analysis constitutes a suitable method for identifying complex food preferences as well as a useful tool for comparing dietary behaviour across individual populations. In addition to a lack of information on Central European dietary patterns, dietary data featuring a longitudinal aspect are likewise largely unavailable for the region. Our study thus strives to address this gap by analysing children’s dietary patterns, their stability and possible changes at 7, 11 and 15 years in the Czech part of the European Longitudinal Study of Pregnancy and Childhood (ELSPAC–CZ).

We analysed dietary data based on the self-reported semi-quantitative FFQ obtained in 1998, 2002 and 2006. Dietary patterns were derived using factor analysis for each period, followed by the determination of dietary pattern stability across the individual periods.

The analysis of dietary patterns was based on longitudinal children’s dietary data from the geographical region that was undergoing massive socio-economic changes at the time of birth of the study subjects.

All participants were children. At 7 years the analysis included 3220 children, at 11 years the analysis included 2509 children and at 15 years the analysis included 1589 children.

Two stable children’s dietary patterns labelled as ‘prudent’ and ‘junk food’ were identified across all three time points (7, 11 and 15 years).

This study identifies stable longitudinal trends in the dietary behaviour of children enrolled in the ELSPAC-CZ study.

Inflammation has been suggested to play an important role in the development and progression of metabolic syndrome (MetS). Dietary inflammatory index (DII), a measurement of inflammatory potential in diets, was suggested to be associated with MetS. The aim of this systematic review and meta-analysis was to establish the associations of DII with MetS and its components based on available observational studies.

Systematic review and meta-analysis.

A comprehensive literature search of studies that assessed the associations between DII and MetS was conducted in PubMed, Medline and Embase, using a combination of search terms relating to DII and MetS.

Eighteen articles were eligible, of which fourteen were cross-sectional and four were cohort in design.

Results from the random effects meta-analysis showed significantly positive associations of higher DII (top v. bottom quartiles) with MetS (OR: 1·23 (95 % CI 1·10, 1·37)), abdominal obesity (OR: 1·15 (95 % CI 1·02, 1·29)), high blood pressure (OR: 1·17 (95 % CI 1·07, 1·29)), hyperglycaemia (OR: 1·18 (95 % CI 1·05, 1·33)) and hypertriacylglycerolaemia (OR: 1·17 (95 % CI 1·07, 1·28)). The effects of summary OR became stronger when analyses were restricted to cohorts, studies that adjudged for covariates (including BMI, physical activity and total energy intake).

Higher DII, representing pro-inflammatory diet, is associated with higher odds of MetS and its components, except for low HDL-cholesterol. The findings prompt dietary interventions for preventing MetS from the aspect of inflammation.

To examine the influence of prenatal artificial sweetener (AS) consumption on birth outcomes.

Systematic review and meta-analysis.

Online databases (Medline, CINAHL, Embase, Cochrane Library, Scopus, Web of Science, FSTA – the food resource database, and ClinicalTrials.gov) were searched up to 9 April 2020. Studies of all designs (except case studies and reviews) were eligible, which contained information on the relevant population (pregnant women), intervention/exposure (any AS consumption), comparator (no AS consumption) and birth outcomes (preterm delivery, gestational age, birth weight).

From 677 citations, ten cohort studies and one randomised controlled trial (n 138 007 women) were included. ‘Low’ to ‘very low’ certainty evidence revealed that daily consumption of AS was associated with an increased risk of preterm delivery (three studies, n 129 009; risk ratio = 1·18, 95 % CI 1·09, 1·28, I2 = 9 %), a 24 g increase in birth weight (three studies, n 64 417; mean difference (MD): 23·74 g, 95 % CI 0·89, 45·58, I2 = 0 %) and a 0·11 week decrease in gestational age (three studies, n 64 417; MD: –0·11 weeks, 95 % CI –0·19, –0·03, I2 = 0 %).

‘Low’ to ‘very low’ certainty evidence suggests daily AS consumption during pregnancy is associated with an increased risk of preterm delivery, increased birth weight and decreased gestational age. Additional ‘high’-quality research is urgently needed to further assess these relationships.

Food insecurity is a structural barrier to HIV care in peri-urban areas in South Africa (SA), where approximately 80 % of households are moderately or severely food insecure. For people with HIV (PWH), food insecurity is associated with poor antiretroviral therapy adherence and survival rates. Yet, measurement of food insecurity among PWH remains a challenge.

The current study examines the factor structure of the nine-item Household Food Insecurity Access Scale (HFIAS, isiXhosa-translated) among PWH in SA using a restrictive bifactor model.

Primary care clinics in Khayelitsha, a peri-urban settlement in Cape Town, SA.

Participants (n 440) were PWH who received HIV care in Khayelitsha screening for a clinical trial. Most were categorised as severely (n 250, 56·82 %) or moderately (n 107, 24·32 %) food insecure in the past 30 d.

Revised parallel analysis suggested a three-factor structure, which was inadmissible. A two-factor structure was examined but did not adequately fit the data. A two-factor restrictive bifactor model was examined, such that all items loaded on a general factor (food insecurity) and all but two items loaded on one of two specific additional factors, which adequately fit the data (comparative fit index = 0·995, standardised root mean square residual = 0·019). The two specific factors identified were: anxiety/insufficient quality and no food intake. Reliability was adequate (ω = 0·82).

Results supported the use of a total score, and identified two specific factors of the HFIAS, which may be utilised in future research and intervention development. These findings help identify aspects of food insecurity that may drive relationships between the construct and important HIV-related variables.

The current study aimed to understand how moderate and severe food-insecure people living with HIV (PLHIV) in the Dominican Republic perceive a healthy diet and explore facilitators and barriers to engaging in healthy dietary behaviours as a means of HIV self-management.

We conducted semi-structured interviews with PLHIV. We generated codes on food insecurity among PLHIV and used content analysis to organise codes for constant comparison between and within participants.

Two urban HIV clinics in the Dominican Republic.

Thirty-two PLHIV participated in the interviews.

Factors that contributed to dietary behaviours include individual factors, such as knowledge of nutrition, views and attitudes on healthy dietary behaviours, beliefs about dietary needs for PLHIV and diet functionality. Interpersonal factors, including assistance from family and peers in providing food or funds, were deemed critical along with community and organisational factors, such as food assistance from HIV clinics, accessibility to a variety of food store types and the availability of diverse food options at food stores. Policy-level factors that influenced dietary behaviours were contingent on respondents’ participation in the labour market (i.e. whether they were employed) and consistent access to government assistance. Food insecurity influenced these factors through unpredictability and a lack of control.

PLHIV who experience food insecurity face various barriers to engaging in healthy dietary behaviours. Their diets are influenced at multiple levels of influence ranging from individual to structural, requiring multi-level interventions that can address these factors concurrently.

To examine associations between diet and risk of developing gastro-oesophageal reflux disease (GERD).

Prospective cohort with a median follow-up of 15·8 years. Baseline diet was measured using a FFQ. GERD was defined as self-reported current or history of daily heartburn or acid regurgitation beginning at least 2 years after baseline. Sex-specific logistic regressions were performed to estimate OR for GERD associated with diet quality scores and intakes of nutrients, food groups and individual foods and beverages. The effect of substituting saturated fat for monounsaturated or polyunsaturated fat on GERD risk was examined.

Melbourne, Australia.

A cohort of 20 926 participants (62 % women) aged 40–59 years at recruitment between 1990 and 1994.

For men, total fat intake was associated with increased risk of GERD (OR 1·05 per 5 g/d; 95 % CI 1·01, 1·09; P = 0·016), whereas total carbohydrate (OR 0·89 per 30 g/d; 95 % CI 0·82, 0·98; P = 0·010) and starch intakes (OR 0·84 per 30 g/d; 95 % CI 0·75, 0·94; P = 0·005) were associated with reduced risk. Nutrients were not associated with risk for women. For both sexes, substituting saturated fat for polyunsaturated or monounsaturated fat did not change risk. For both sexes, fish, chicken, cruciferous vegetables and carbonated beverages were associated with increased risk, whereas total fruit and citrus were associated with reduced risk. No association was observed with diet quality scores.

Diet is a possible risk factor for GERD, but food considered as triggers of GERD symptoms might not necessarily contribute to disease development. Potential differential associations for men and women warrant further investigation.

To conduct formative research using qualitative methods among stakeholders of secondary schools to explore their perceptions, barriers and facilitators related to healthy eating and physical activity (PA) among Malaysian adolescents.

A qualitative study involving eight focus groups and twelve in-depth interviews. Focus groups and interviews were recorded and transcribed verbatim. An inductive thematic analysis approach was used to analyse the data.

Four secondary schools in Perak and Selangor states (two urban and two rural schools) in Malaysia.

Focus groups were conducted with seventy-six adolescents aged 13–14 years, and in-depth interviews were conducted with four headmasters, four PA education teachers and four food canteen operators.

Stakeholders thought that adolescents’ misperceptions, limited availability of healthy options, unhealthy food preferences and affordability were important challenges preventing healthy eating at school. Low-quality physical education (PE) classes, limited adolescent participation and teachers’ commitment during lessons were perceived as barriers to adolescents being active at school. Affordability was the main challenge for adolescents from rural schools. Stakeholders perceived that a future school-based intervention should improve the availability and subsidies for healthy foods, provide health education/training for both adolescents and PE teachers, enhance active adolescent participation in PE and develop social support mechanisms to facilitate engagement with PA.

These findings provide important insights into developing school-based lifestyle interventions to improve healthy eating and strengthening PA of Malaysian adolescents.

The project aimed to validate a short questionnaire (CoCu pregnancy – Composition and Culture of Eating during pregnancy) and to investigate associations with age and socio-economic status (SES).

The questionnaire was developed according to the validated CoCu for children and adolescents containing a diet composition (fourteen items) and a culture of eating part (six items). A Nutritional Health Score (NHS) was calculated based on diet composition (–120 and +120, with higher scores indicating healthier diets). The validity was assessed by comparing answers in CoCu pregnancy with a FFQ. In a subsample (n 97), we assessed the percentage of having chosen the same (or adjacent) response categories in the 24th and 36th week of pregnancy (wp).

Data were collected within the LIFE Child study in Leipzig, Germany.

We evaluated 430 questionnaires of pregnant women (24th wp).

The results indicated a healthy diet in the present sample (NHS at 24th wp = 49·74 (95 % CI 47·27, 52·22)). The analyses revealed significant positive correlations between CoCu and FFQ (rho ranging from 0·32 to 0·61). For each food item, >90 % of women had chosen the same (50–60 %) or adjacent response categories in the 24th and 36th wp. The analysis revealed associations of the NHS with age (β = 0·11, P = 0·027), SES (β = 0·21, P < 0·001), snacking (β = –0·24, P < 0·001) and media use (β = –0·18, P < 0·001).

The questionnaire represents a useful tool for surveying the diets during pregnancy for research and clinical practice.

To examine participants’ experiences with nutrition education classes that were implemented with and designed to complement a cost-offset community-supported agriculture (CSA) programme.

Qualitative analysis of data from twenty-eight focus groups with ninety-six participants enrolled in Farm Fresh Foods for Healthy Kids (F3HK). Transcribed data were coded and analysed by a priori and emergent themes.

Rural and micropolitan communities in New York, North Carolina, Vermont and Washington (USA).

Ninety-six F3HK participants.

Participants found recipes and class activities helpful and reported improvements in nutrition knowledge, food preservation skills and home cooking behaviours for themselves and their children; they also reported that classes promoted a sense of community. Some educators better incorporated CSA produce into lessons, which participants reported as beneficial. Other obligations and class logistics were barriers to attendance; participants recommended that lessons be offered multiple times weekly at different times of day. Other suggestions included lengthening class duration to encourage social engagement; emphasising recipes to incorporate that week’s CSA produce and pantry staples and offering additional strategies to incorporate children in classes.

Complementing a cost-offset CSA with nutrition education may enhance programme benefits to low-income families by improving nutrition knowledge and cooking behaviours. However, future interventions will benefit from ongoing coordination between educators and local growing trajectories to maximise timely coverage of unfamiliar produce in lessons; synchronous scheduling of CSA pick-up and classes for participant convenience and creative strategies to engage children and/or provide childcare.

To describe diet quality (Healthy Eating Index 2010 (HEI-2010) and Healthy Eating Index 2015 (HEI-2015)) according to self-reported cannabis use among the National Health and Nutrition Examination Survey (NHANES) adult participants.

Utilizing cross-sectional data, we assessed diet quality with up to two 24-h diet recalls from NHANES participants. Usual intakes were estimated via the multivariate Markov Chain–Monte Carlo method. Diet quality scores were compared among never users, previous users and current users of cannabis.

NHANES surveys from 2005 to 2016.

Adult NHANES participants (17 855) aged 20–59 years with valid data for dietary recalls and drug use questionnaires.

Current adult cannabis users (ages 20–59 years) had significantly lower total diet quality (HEI-2010) scores (51·8 ± 0·7) compared with previous (56·2 ± 0·4) and never users (57·7 ± 0·4). Similar differences in total and individual HEI-2015 scores were observed. For the HEI-2015 scores, cannabis users had a significantly higher (better) sodium scores (4·1 ± 0·2) compared with never users (3·3 ± 0·1) and previous users (3·2 ± 0·1). Cannabis users scored lower compared with never users on total vegetables (3·1 ± 0·1 v. 3·7 ± 0·0), total fruit (2·1 ± 0·1 v. 3·0 ± 0·1) and whole fruit (2·2 ± 0·1 v. 3·3 ± 0·1) for the HEI-2015 index.

Current cannabis users’ usual intakes reflect lower diet quality compared with never or previous users, particularly lower subcomponent scores of total vegetables, greens and beans, total fruit and whole fruit. Cannabis users should increase their intake of fruit and vegetables to improve overall diet quality.
