The present study assessed the nutrition information displayed on ready-to-eat packaged foods and the nutritional quality of those food products in Thailand.
Design
In March 2015, the nutrition information panels and nutrition and health claims on ready-to-eat packaged foods were collected from the biggest store of each of the twelve major retailers, using protocols developed by the International Network for Food and Obesity/Non-communicable Diseases Research, Monitoring and Action Support (INFORMAS). The Thai Nutrient Profile Model was used to classify food products according to their nutritional quality as ‘healthier’ or ‘less healthy’.
Results
In total, information from 7205 food products was collected across five broad food categories. Out of those products, 5707 (79·2 %), 2536 (35·2 %) and 1487 (20·6 %) carried a nutrition facts panel, a Guideline Daily Amount (GDA) label and health-related claims, respectively. Only 4691 (65·1 %) and 2484 (34·5 %) of the products that displayed the nutrition facts or a GDA label, respectively, followed the guidelines of the Thai Food and Drug Administration. In total, 4689 products (65·1 %) could be classified according to the Thai Nutrient Profile Model, of which 432 products (9·2 %) were classified as healthier. Moreover, among the 1487 products carrying health-related claims, 1219 (82·0 %) were classified as less healthy. Allowing less healthy food products to carry claims could mislead consumers and result in overconsumption of ready-to-eat food products.
Conclusions
The findings suggest effective policies should be implemented to increase the relative availability of healthier ready-to-eat packaged foods, as well as to improve the provision of nutrition information on labels in Thailand.
To understand parents’ knowledge and use of nutrition labelling and to explore its associated factors.
Design
Cross-sectional survey.
Setting
Two schools providing a nine-year educational programme in Putuo District, Shanghai, China, were selected for the study. Information was included on demographic data and knowledge of the Chinese Food Pagoda.
Subjects
Students and their parents (n 1770) participated in a questionnaire survey.
Results
Of questionnaires, 1766 were completed (response rate 99·8 %). Utilization rate of nutrition labelling was 19·3 %. Among 624 parents knowing nutrition labelling, 22·1 % understood all the information included, 70·7 % understood it partially and 7·2 % could not understand it at all. Use of nutrition labelling by parents was related to the following factors (OR; 95 % CI): high educational level of parent (1·465; 1·165, 1·841), parent’s knowledge of the Chinese Food Pagoda (1·333; 1·053, 1·688), parent’s consumption of top three snacks which are unhealthy (1·065; 1·023, 1·109), parent’s assumption that nutrition labelling would affect their choice of food (1·522; 1·131, 2·048), student’s willingness to learn about labels (1·449; 1·093, 1·920) and student’s knowledge and use of labels (2·214; 1·951, 2·513).
Conclusions
Parents’ knowledge and use of nutrition labelling are still at a lower level, and some information included in the nutrition labels is not understood by parents. The forms of the existing nutrition labelling need to be continuously improved to facilitate their understanding and usefulness. It is necessary to establish nutrition projects focusing on education and use of nutrition labels which help parents and their children make the right choices in selecting foods.
The objective of the present study was to test the effectiveness of financial incentives and traffic-light labels to reduce purchases of sugar-sweetened beverages in a community supermarket.
Design
In this randomized controlled trial, after a 2-month baseline period (February–March 2014), in-store traffic-light labels were posted to indicate healthy (green), less healthy (yellow) or unhealthy (red) beverages. During the subsequent five months (April–August 2014), participants in the intervention arm were eligible to earn a $US 25 in-store gift card each month they refrained from purchasing red-labelled beverages.
Setting
Urban supermarket in Chelsea, MA, USA, a low-income Latino community.
Subjects
Participants were customers of this supermarket who had at least one child living at home. A total of 148 customers (n 77 in the intervention group and n 71 in the control group) were included in the final analyses.
Results
Outcomes were monthly in-store purchases tracked using a store loyalty card and self-reported consumption of red-labelled beverages. Compared with control participants, the proportion of intervention participants who purchased any red-labelled beverages decreased by 9 % more per month (P=0·002). More intervention than control participants reduced their consumption of red-labelled beverages (−23 % v. −2 % for consuming ≥1 red beverage/week, P=0·01).
Conclusions
Overall, financial incentives paired with in-store traffic-light labels modestly reduced purchase and consumption of sugar-sweetened beverages by customers of a community supermarket.
The present research aimed to investigate the impact of the physical activity calorie equivalent (PACE) front-of-pack label on consumption, prospective consumption and liking of familiar and unfamiliar discretionary snack foods.
Design
In a within-subject randomised design, participants tasted and rated liking (9-point hedonic scale) and prospective consumption (9-point category scale) of four different snack foods with four different labels (i.e. blank, fake, PACE, PACE doubled) and four control snack foods. The twenty snack foods were presented during two 45 min sessions (i.e. ten snack foods per session) which were separated by one week. The amount participants sampled of each snack food was measured.
Setting
The study was conducted in the Centre for Advanced Sensory Sciences laboratory at Deakin University, Australia.
Subjects
The participants were 153 university students (126 females, twenty-seven males, mean age 24·3 (sd 4·9) years) currently enrolled in an undergraduate nutrition degree at Deakin University.
Results
When the PACE label was present on familiar snack foods, participants sampled 9·9 % (22·8 (sem 1·4) v. 25·3 (sem 1·5) g, P=0·03) less than when such label was not present. This was in line with a decreased prospective snack food consumption of 9·1 % (3·0 (sem 0·2) v. 3·3 (sem 0·2) servings, P=0·03). Such pattern was not seen in unfamiliar snacks.
Conclusions
The PACE label appears to be a promising way to decrease familiar discretionary snack food consumption in young, health-minded participants.
To develop health-endorsement logos (HEL) for food products indicating healthy choices based on the South African nutrient profile model and to pilot test these logos with consumers.
Design
Multistage mixed-methods design.
Setting
Cape Town, South Africa.
Subjects
Nine focus group discussions (FGD) were conducted with adult consumers to explore what types of HEL are preferred and why. Based on the findings, ten HEL were designed by a graphic design team. A modified Delphi technique, conducted with experts in the fields of nutrition and food science, was employed to eliminate lowest-scoring HEL and to improve the design of the remaining logos. Participants from the initial FGD participated in pilot testing the improved logos.
Results
Participants from FGD (n 67) were positive about a single HEL, stating it would make food labelling less confusing as they did not understand the various HEL used. Participants indicated the logo should include wording related to ‘healthy choice’ or ‘better choice’ and pictures/symbols related to health and/or food. During two rounds of scoring and comments by experts (n 19), five logos were eliminated and the design of the remaining five improved. Three of five remaining logos received overall rankings of 3·08/5, 3·28/5 and 3·39/5, respectively, during FGD (n 36) in the pilot-testing phase.
Conclusion
HEL were designed and consumer tested. Three designs were submitted to the national Department of Health to consider for implementation, after further testing, as a tool to assist in addressing the high incidence of non-communicable diseases in South Africa.
Differences in bottled v. tap water intake may provide insights into health disparities, like risk of dental caries and inadequate hydration. We examined differences in plain, tap and bottled water consumption among US adults by sociodemographic characteristics.
Design
Cross-sectional analysis. We used 24 h dietary recall data to test differences in percentage consuming the water sources and mean intake between groups using Wald tests and multiple logistic and linear regression models.
Setting
National Health and Nutrition Examination Survey (NHANES), 2007–2014.
Subjects
A nationally representative sample of 20 676 adults aged ≥20 years.
Results
In 2011–2014, 81·4 (se 0·6) % of adults drank plain water (sum of tap and bottled), 55·2 (se 1·4) % drank tap water and 33·4 (se 1·4) % drank bottled water on a given day. Adjusting for covariates, non-Hispanic (NH) Black and Hispanic adults had 0·44 (95 % CI 0·37, 0·53) and 0·55 (95 % CI 0·45, 0·66) times the odds of consuming tap water, and consumed B=−330 (se 45) ml and B=−180 (se 45) ml less tap water than NH White adults, respectively. NH Black, Hispanic and adults born outside the fifty US states or Washington, DC had 2·20 (95 % CI 1·79, 2·69), 2·37 (95 % CI 1·91, 2·94) and 1·46 (95 % CI 1·19, 1·79) times the odds of consuming bottled water than their NH White and US-born counterparts. In 2007–2010, water filtration was associated with higher odds of drinking plain and tap water.
Conclusions
While most US adults consumed plain water, the source (i.e. tap or bottled) and amount differed by race/Hispanic origin, nativity status and education. Water filters may increase tap water consumption.
To explore whether there is an association between socio-economic status and maternal BMI and duration of any breast-feeding/exclusive breast-feeding among Norwegian infants at 4 and 5 months of age in 2016.
Design
Cross-sectional design. Baseline data from a randomized controlled trial. Data concerning breast-feeding were collected by FFQ.
Setting
Recruitment was done at child health-care centres and through Facebook in 2016. In total, 960 infants/parents registered for participating in the study Early Food for Future Health.
Subjects
A total of 715 infant/mother dyads completed the questionnaire when the child was between 5 and 6 months old.
Results
At 5 months of age, 81·0 % of infants were breast-fed and 16·4 % were exclusively breast-fed. Infants of highly educated mothers had higher odds of being breast-fed at 5 months compared with infants of mothers with less education. Infants of multiparous mothers had higher odds of being exclusively breast-fed for the first 5 months compared with infants of mothers with one child. Infants of mothers with overweight/obesity had reduced odds of both being breast-fed at all and being exclusively breast-fed at 4 months of age compared with infants of mothers with normal BMI.
Conclusions
Our results show that duration of breast-feeding varies with socio-economic status and maternal BMI in Norway. Targeting groups with low socio-economic status and mothers with overweight or obesity is important, as they are less likely to breast-feed according to recommendations.
The goal of the present study was to use a methodology that accurately and reliably describes the availability, price and quality of healthy foods at both the store and community levels using the Nutrition Environment Measures Survey in Stores (NEMS-S), to propose a spatial methodology for integrating these store and community data into measures for defining objective food access.
Setting
Two hundred and sixty-five retail food stores in and within 2 miles (3·2 km) of Flint, Michigan, USA, were mapped using ArcGIS mapping software.
Design
A survey based on the validated NEMS-S was conducted at each retail food store. Scores were assigned to each store based on a modified version of the NEMS-S scoring system and linked to the mapped locations of stores. Neighbourhood characteristics (race and socio-economic distress) were appended to each store. Finally, spatial and kernel density analyses were run on the mapped store scores to obtain healthy food density metrics.
Results
Regression analyses revealed that neighbourhoods with higher socio-economic distress had significantly lower dairy sub-scores compared with their lower-distress counterparts (β coefficient=−1·3; P=0·04). Additionally, supermarkets were present only in neighbourhoods with <60 % African-American population and low socio-economic distress. Two areas in Flint had an overall NEMS-S score of 0.
Conclusions
By identifying areas with poor access to healthy foods via a validated metric, this research can be used help local government and organizations target interventions to high-need areas. Furthermore, the methodology used for the survey and the mapping exercise can be replicated in other cities to provide comparable results.
There is currently no standard, objective definition of selective eating. This is partially because normative values for the number of different foods eaten by US children have not been established. The present study objectives were to: (i) perform exploratory analysis on the number of different foods, beverages, and total foods and beverages consumed by US children aged 2–18 years over a year’s time, and the types of foods consumed by those in the lowest 2·5th percentile; and (ii) determine whether those values differ according to demographic variables and weight status.
Design
Secondary analysis of cross-sectional FFQ data. Differences in number of foods, beverages, and total foods and beverages were analysed using one-way ANOVA.
Setting
National Health and Nutrition Examination Survey (NHANES) for the years 2003–2006.
Subjects
Non-institutionalized US children aged 2–18 years.
Results
The mean number of different foods and beverages consumed across the sample was 83·2. There were no significant differences by gender, BMI, race or food security categories. There was a difference in beverage consumption by age category, with children aged 12–18 years consuming a significantly higher number of different beverages compared with each of the other two age categories (i.e. 2–5 years and 6–11 years).
Conclusions
Normative values for the number of foods and drinks reported as consumed by children over the past 12 months may be a useful measure for researchers. Future research validating this measure is needed before cut-off values can be used to develop a definition of selective eating.
To assess the accuracy of nutrient intake calculations from leading nutrition tracking applications (apps).
Design
Nutrient intake estimates from thirty 24 h dietary recalls collected using Nutrition Data System for Research (NDSR) were compared with intake calculations from these recalls entered by the researcher into five free nutrition tracking apps. Apps were selected from the Apple App Store based on consumer popularity from the list of free ‘Health and Fitness’ apps classified as a nutrition tracking apps.
Subjects
Dietary recall data collected from thirty lower-income adults.
Results
Correlations between nutrient intake calculations from NDSR and the nutrition tracking apps ranged from 0·73 to 0·96 for energy and macronutrients. Correlations for the other nutrients examined (Na, total sugars, fibre, cholesterol, saturated fat) ranged from 0·57 to 0·93. For each app, one or more mean nutrient intake calculations were significantly lower than those from NDSR. These differences included total protein (P=0·03), total fat (P=0·005), Na (P=0·02) and cholesterol (P=0·005) for MyFitnessPal; dietary fibre (P=0·04) for Fitbit; total protein (P=0·0004), total fat (P=0·008), Na (P=0·002), sugars (P=0·007), cholesterol (P=0·0006) and saturated fat (P=0·005) for Lose It!; Na (P=0·03) and dietary fibre (P=0·005) for MyPlate; and total fat (P=0·03) for Lifesum.
Conclusions
Findings suggest that nutrient calculations from leading nutrition tracking apps tend to be lower than those from NDSR, a dietary analysis software developed for research purposes. Further research is needed to evaluate the validity of the apps when foods consumed are entered by consumers.
Encouraging people to eat more seafood can offer a direct, cost-effective way of improving overall health outcomes. However, dietary recommendations to increase seafood consumption have been criticised following concern over the capacity of the seafood industry to meet increased demand, while maintaining sustainable fish stocks. The current research sought to investigate Australian accredited practising dietitians’ (APD) and public health nutritionists’ (PHN) views on seafood sustainability and their dietary recommendations, to identify ways to better align nutrition and sustainability goals.
Design
A self-administered online questionnaire exploring seafood consumption advice, perceptions of seafood sustainability and information sources of APD and PHN. Qualitative and quantitative data were collected via open and closed questions. Quantitative data were analysed with χ2 tests and reported using descriptive statistics. Content analysis was used for qualitative data.
Setting
Australia.
Subjects
APD and PHN were targeted to participate; the sample includes respondents from urban and regional areas throughout Australia.
Results
Results indicate confusion around the concept of seafood sustainability and where to obtain information, which may limit health professionals’ ability to recommend the best types of seafood to maximise health and sustainability outcomes. Respondents demonstrated limited understanding of seafood sustainability, with 7·5 % (n 6/80) satisfied with their level of understanding.
Conclusions
Nutrition and sustainability goals can be better aligned by increasing awareness on seafood that is healthy and sustainable. For health professionals to confidently make recommendations, or identify trade-offs, more evidence-based information needs to be made accessible through forums such as dietetic organisations, industry groups and nutrition programmes.
To analyse the content and extent of marketing of ultra-processed food products (UPP) and their brand pages on Facebook, which are highly accessed by Brazilians.
Design
Descriptive.
Setting
Sixteen UPP brand pages on Facebook were selected from 250 pages that were the most liked by Brazilians in October 2015.
Subjects
We analysed the frequency of ‘likes’ and members ‘talking about’ each one of the pages, in addition to fifteen marketing techniques used in the previous year (September 2014 to October 2015). The number of posts, likes, ‘shares’ and ‘commentaries’, and the mean number of likes, shares and commentaries per post, were collected for one month, from 23 September to 23 October 2015.
Results
The two most liked pages were: Coke® (93 673 979 likes) and McDonald’s® (59 749 819 likes). Regarding the number of people talking about the pages, McDonald’s led with 555 891 commentaries, followed by Coke (287 274), Burger King® (246 148) and Kibon® (244 523). All pages used marketing techniques, which included photos, user conversations, presence of brand elements and links. Videos were observed on 93·8 % of the pages; promotions on 68·8 %; and celebrities on 62·5 %. In one month, Garoto®, Outback® and Coke were brands that published more than one post per day. Kibon achieved the highest ratio of likes per post (285 845·50) and Burger King had the highest mean shares per post (10 083·93), including commentaries per post (7958·13).
Conclusions
UPP marketing is extensively used on Facebook pages and is highly accessed by Brazilians, with UPP companies employing a diversity of marketing strategies.
To characterise parent presentations of fussy eating and mealtime interactions at a point of crisis, through analyses of real-time recordings of calls to a parenting helpline.
Design
Qualitative analysis included an inductive thematic approach to examine clinical parent presentations of fussy eating and derive underlying themes relating to mealtime interactions.
Setting
Calls made to the Child Health Line regarding feeding concerns were recorded and transcribed verbatim.
Subjects
From a corpus of 723 calls made during a 4-week period in 2009, twelve were from parents of children aged 6–48 months.
Results
Parents of infants (≤12 months, n 6) presented feeding concerns as learning challenges in the process of transitioning from a milk-based to a solid-based diet, while parents of toddlers (13–48 months, n 6) presented emotional accounts of feeding as an intractable problem. Parents presented their child’s eating behaviour as a battle (conflict), in which their children’s agency over limited intake and variety of foods (child control) was constructed as ‘bad’ or ‘wrong’. Escalating parent anxiety (parent concern) had evoked parent non-responsive feeding practices or provision of foods the child preferred.
Conclusions
Real-time descriptions of young children’s fussy eating at a time of crisis that initiated parents’ call for help have captured the highly charged emotional underpinnings of mealtime interactions associated with fussy eating. Importantly, they show the child’s emerging assertion of food autonomy can escalate parents’ emotional distress that, in the short term, initiates non-responsive feeding practices. The current study identifies the importance of educational and emotional support for parents across the period of introducing solids.
To identify predominant dietary patterns in four African populations and examine their association with obesity.
Design
Cross-sectional study.
Setting/Subjects
We used data from the Africa/Harvard School of Public Health Partnership for Cohort Research and Training (PaCT) pilot study established to investigate the feasibility of a multi-country longitudinal study of non-communicable chronic disease in sub-Saharan Africa. We applied principal component analysis to dietary intake data collected from an FFQ developed for PaCT to ascertain dietary patterns in Tanzania, South Africa, and peri-urban and rural Uganda. The sample consisted of 444 women and 294 men.
Results
We identified two dietary patterns: the Mixed Diet pattern characterized by high intakes of unprocessed foods such as vegetables and fresh fish, but also cold cuts and refined grains; and the Processed Diet pattern characterized by high intakes of salad dressing, cold cuts and sweets. Women in the highest tertile of the Processed Diet pattern score were 3·00 times more likely to be overweight (95 % CI 1·66, 5·45; prevalence=74 %) and 4·24 times more likely to be obese (95 % CI 2·23, 8·05; prevalence=44 %) than women in this pattern’s lowest tertile (both P<0·0001; prevalence=47 and 14 %, respectively). We found similarly strong associations in men. There was no association between the Mixed Diet pattern and overweight or obesity.
Conclusions
We identified two major dietary patterns in several African populations, a Mixed Diet pattern and a Processed Diet pattern. The Processed Diet pattern was associated with obesity.
To identify optimal food choices that meet nutritional recommendations to reduce prevalence of inadequate nutrient intakes.
Design
Linear programming was used to obtain an optimized diet with sixty-eight foods with the least difference from the observed population mean dietary intake while meeting a set of nutritional goals that included reduction in the prevalence of inadequate nutrient intakes to ≤20 %.
Setting
Brazil.
Subjects
Participants (men and women, n 25 324) aged 20 years or more from the first National Dietary Survey (NDS) 2008–2009.
Results
Feasible solution to the model was not found when all constraints were imposed; infeasible nutrients were Ca, vitamins D and E, Mg, Zn, fibre, linolenic acid, monounsaturated fat and Na. Feasible solution was obtained after relaxing the nutritional constraints for these limiting nutrients by including a deviation variable in the model. Estimated prevalence of nutrient inadequacy was reduced by 60–70 % for most nutrients, and mean saturated and trans-fat decreased in the optimized diet meeting the model constraints. Optimized diet was characterized by increases especially in fruits (+92 g), beans (+64 g), vegetables (+43 g), milk (+12 g), fish and seafood (+15 g) and whole cereals (+14 g), and reductions of sugar-sweetened beverages (−90 g), rice (−63 g), snacks (−14 g), red meat (−13 g) and processed meat (−9·7 g).
Conclusion
Linear programming is a unique tool to identify which changes in the current diet can increase nutrient intake and place the population at lower risk of nutrient inadequacy. Reaching nutritional adequacy for all nutrients would require major dietary changes in the Brazilian diet.
In the present study we investigated gender-specific associations of low birth weight (LBW) and shorter relative leg length with metabolic syndrome (MetS) after adjusting for sociodemographic characteristics and health-related behaviours. We also investigated whether these associations are independent of age at menarche and BMI at 20 years old.
Design
Cross-sectional analysis.
Subjects
Baseline data from 12 602 participants (35–74 years) of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil), 2008–2010.
Setting
MetS was defined according to the revised National Cholesterol Education Program Adult Treatment Panel III guidelines. LBW (<2·5 kg) and age- and sex-standardized relative leg length (high, medium and low) were the explanatory variables studied. The strength of the associations between the explanatory variables and MetS was estimated by Poisson regression with robust variance.
Results
MetS prevalence was 34·2 %; it was more prevalent in men (36·8 %) than in women (32·2 %). In multivariate analysis, LBW was associated (prevalence ratio; 95 % CI) with MetS only in women (1·28; 1·24, 1·45). Shorter leg length was associated with MetS in both men (1·21; 1·09, 1·35 and 1·46; 1·29, 1·65 for low and medium lengths, respectively) and women (1·12; 1·00, 1·25 and 1·40; 1·22, 1·59 for low and medium lengths, respectively). Additional adjustments for age at menarche and BMI at 20 years old did not change the associations.
Conclusions
Poor nutritional status as estimated by LBW and lower leg length in childhood was associated with a higher prevalence of MetS, although LBW was a significant factor only among women.
High frequency of low birth weight (LBW) is observed in rural compared with urban Indian women. Since maternal BMI is known to be associated with pregnancy outcomes, the present study aimed to investigate factors associated with BMI in early pregnancy of urban and rural South Indian women.
Design
Prospective observational cohort.
Setting
A hospital-based study conducted at an urban and a rural health centre in Karnataka State.
Subjects
Pregnant women (n 843) aged 18–40 years recruited in early pregnancy from whom detailed sociodemographic, environmental, anthropometric and dietary intake information was collected.
Results
A high proportion of low BMI (32 v. 26 %, P<0·000) and anaemia (48 v. 23 %, P<0·000) was observed in the rural v. the urban cohort. Rural women were younger, had lower body weight, tended to be shorter and less educated. They lived in poor housing conditions, had less access to piped water and good sanitation, used unrefined fuel for cooking and had lower standard of living score. The age (β=0·21, 95 % CI 0·14, 0·29), education level of their spouse (β=1·36, 95 % CI 0·71, 2·71) and fat intake (β=1·24, 95 % CI 0·20, 2·28) were positively associated with BMI in urban women.
Conclusions
Our findings indicate that risk factors associated with BMI in early pregnancy are different in rural and urban settings. It is important to study population-specific risk factors in relation to perinatal health.
To explore Chinese mothers’ experiences, emotions and expectations of breast-feeding in public places.
Design
Exploratory qualitative study. Purposive sampling was used to recruit participants and face-to-face interviews were conducted. Themes were identified by content analysis.
Setting
Two different geographical communities in Wuhan, Hubei Province, central China, March–May 2016.
Subjects
A total of twenty-seven mothers aged 23–33 years, who had one child under 3 years of age and had experience of breast-feeding in public places.
Results
Seven themes emerged from the interviews: struggling to balance infant’s needs and personal feelings; embarrassed or natural emotion regarding breast-feeding in public places; effect of cultural and social norms; internalized concerns going beyond actual social reaction; measures to make breast-feeding in public places easier; desire for more public facilities; and expecting emotional support from society members.
Conclusions
More positive social support, favourable policies and necessary facilities were desired to enable mothers to breast-feed in an appropriate public location. Women expected increased public acceptance of breast-feeding practices and support from government health officials to ensure women’s success in breast-feeding in public settings.
How food is produced and consumed has consequences for ecosystems, such as resource use and greenhouse gas (GHG) emission among others. The Mediterranean diet (MedDiet) was proposed as a sustainable dietary model, due to its nutritional, environmental, economic and sociocultural dimensions. However, further evidence is needed. Thus, our objective was to evaluate the impact on resource (land, water and energy) use and GHG emission of better adherence to the MedDiet in a Mediterranean Spanish cohort.
Design
We analysed the dietary pattern of participants through a validated FFQ. The outcomes were land use, water and energy consumption and GHG emission according to MedDiet adherence. The specific environmental footprints of food item production and processing were obtained from different available life-cycle assessments.
Setting
Spanish university graduates.
Subjects
Participants (n 20 363) in the Seguimiento Universidad de Navarra (SUN) cohort.
Results
Better adherence to the MedDiet was associated with lower land use (−0·71 (95 % CI −0·76, −0·66) m2/d), water consumption (−58·88 (95 % CI −90·12, −27·64) litres/d), energy consumption (−0·86 (95 % CI −1·01, −0·70) MJ/d) and GHG emission (−0·73 (95 % CI −0·78, −0·69) kg CO2e/d). A statistically significant linear trend (P<0·05) was observed in all these analyses.
Conclusions
In this Mediterranean cohort, better adherence to the MedDiet was an eco-friendly option according to resource consumption and GHG emission.
