The aim of this research was to investigate whether increased portion sizes of vegetables and decreased portion sizes of meat on main dishes increased the amount of vegetables consumed in a real-life ...restaurant setting without affecting customer satisfaction. The participants were unaware of the experiment.
A cross-over design was used in which three restaurants were randomly assigned to a sequence of an intervention and control condition. In the intervention period, the vegetable portion sizes on the plates of main dishes were doubled (150 g of vegetables instead of 75 g) and the portion sizes of meat on the plates were reduced by an average of 12.5%. In the control period, the portion sizes of the main dishes were maintained as usual. In total, 1006 observations and questionnaires were included.
Vegetable consumption from plates was significantly higher during the intervention period (M = 115.5 g) than during the control period (M = 61.7 g). Similarly, total vegetable consumption (including side dishes) was significantly higher during the intervention period (M = 178.0 g) than during the control period (M = 137.0 g). Conversely, meat consumption was significantly lower during the intervention period (M = 183.1 g) than during the control period (M = 211.1 g). Satisfaction with the restaurant visit did not differ between the intervention period (M = 1.27) and control period (M = 1.35). Satisfaction with the main dish was significantly lower during the intervention period (M = 1.25) than during the control period (M = 1.38), although in both cases, the scores indicated that participants remained (very) satisfied with their main dish.
This study showed that increasing vegetable portions in combination with decreasing meat portions (unknowingly to the consumer) increased the amount of vegetables consumed and decreased the amount of meat consumed. Furthermore, despite the changes in portion sizes, participants remained satisfied with their restaurant visit and main dish. The findings of this study suggest that modifying portion size in restaurants is an effective tool for stimulating vegetable consumption and consequently healthy and sustainable diets.
To examine perspectives on food access among low-income families participating in a cost-offset community-supported agriculture (CO-CSA) programme.
Farm Fresh Foods for Healthy Kids (F3HK) is a ...multicentre randomized intervention trial assessing the effect of CO-CSA on dietary intake and quality among children from low-income families. Focus groups were conducted at the end of the first CO-CSA season. Participants were interviewed about programme experiences, framed by five dimensions of food access: availability, accessibility, affordability, acceptability and accommodation. Transcribed data were coded on these dimensions plus emergent themes.
Nine communities in the US states of New York, North Carolina, Washington and Vermont.
Fifty-three F3HK adults with children.
CSA models were structured by partner farms. Produce quantity was abundant; however, availability was enhanced for participants who were able to select their own produce items. Flexible CSA pick-up times and locations made produce pick-up more accessible. Despite being affordable to most, payment timing was a barrier for some. Unfamiliar foods and quick spoilage hindered acceptability through challenging meal planning, despite accommodations that included preparation advice.
Although CO-CSA may facilitate increased access to fruits and vegetables for low-income families, perceptions of positive diet change may be limited by the ability to incorporate share pick-up into regular travel patterns and meal planning. Food waste concerns may be particularly acute for families with constrained resources. Future research should examine whether CO-CSA with flexible logistics and produce self-selection are sustainable for low-income families and CSA farms.
Each day, tens of millions of restaurant goers, conference attendees, college students, military personnel, and school children serve themselves at buffets--many being all-you-can-eat buffets. ...Knowing how the food order at a buffet triggers what a person selects could be useful in guiding diners to make healthier selections.
The breakfast food selections of 124 health conference attendees were tallied at two separate seven-item buffet lines (which included cheesy eggs, potatoes, bacon, cinnamon rolls, low-fat granola, low-fat yogurt, and fruit). The food order between the two lines was reversed (least healthy to most healthy, and vise-versa). Participants were randomly assigned to choose their meal from one line or the other, and researchers recorded what participants selected.
With buffet foods, the first ones seen are the ones most selected. Over 75% of diners selected the first food they saw, and the first three foods a person encountered in the buffet comprised 66% of all the foods they took. Serving the less healthy foods first led diners to take 31% more total food items (p<0.001). Indeed, diners in this line more frequently chose less healthy foods in combinations, such as cheesy eggs and bacon (r = 0.47; p<0.001) or cheesy eggs and fried potatoes (r= 0.37; p<0.001). This co-selection of healthier foods was less common.
Three words summarize these results: First foods most. What ends up on a buffet diner's plate is dramatically determined by the presentation order of food. Rearranging food order from healthiest to least healthy can nudge unknowing or even resistant diners toward a healthier meal, helping make them slim by design. Health-conscious diners, can proactively start at the healthier end of the line, and this same basic principle of "first foods most" may be relevant in other contexts - such as when serving or passing food at family dinners.
Although it is recommended that childcare centers provide foods consistent with dietary guidelines, the impact of implementing sector-specific guidelines on child outcomes is largely unknown.
This ...study aims to examine the impact of a web-based program and support to implement dietary guidelines in childcare centers on children’s 1) diet; 2) BMI z scores; and 3) child health-related quality of life (HRQoL).
This study was a cluster-randomized controlled trial utilizing a Type-3 Hybrid implementation-effectiveness design conducted between October 2016 and March 2018. This study reports on child outcomes. Fifty-four childcare centers in New South Wales, Australia were randomly assigned to the intervention (a web-based menu-planning tool and support) or control group (usual care). The intervention was designed to address barriers and enablers to dietary guideline implementation according to the Theoretical Domains Framework. A quota of 35 consenting childcare centers undertook child-level evaluation of dietary intake where 522 parents consented to completing ≥1 component of data collection for their child. Child consumption of core and discretionary (unhealthy) foods while in care was assessed via dietary observations by blinded research assistants, childcare diet quality was assessed via educator-completed questionnaires, BMI z scores were assessed via measured weight and height, and child HRQoL was assessed via parent report at baseline and 12-mo follow-up.
There was a significant increase in mean child consumption of fruit (0.39 servings; 95% CI: 0.12, 0.65 servings) and dairy foods (0.38 servings; 95% CI: 0.19, 0.57 servings) and a significant reduction in consumption of discretionary foods (−0.40 servings; 95% CI: −0.64, −0.16 servings) in care in the intervention group, relative to control at 12-mo follow-up. No significant differences were observed in diet quality, BMI z scores, or HRQoL.
A web-based intervention to support planning of childcare menus consistent with dietary guidelines can improve child consumption of healthier foods in daycare. This trial was registered at www.anzctr.org.au as ACTRN12616000974404.
Major sporting event catering is a significant undertaking for foodservice providers, particularly with an increasing focus on sustainability, global health, and nutrition demands of athletes. Yet, ...the inclusion of nutrition expertise in catering varies significantly between events. Foodservice systems models are commonly used to evaluate foodservice operations but to date have not been applied to catering and nutrition at major sporting events.
The aim of this exploratory case study was to gain in-depth insights of key stakeholders (catering management, chefs, organizers, and dietitians) regarding the integration of nutrition into the catering operation of a major global sporting event, with a focus on future continuity, and map this to the foodservice systems model using a program logic model.
Semistructured interviews were conducted with 12 stakeholders during and after the 2018 Commonwealth Games, Gold Coast, Australia.
The 8 themes that emerged were related to planning and preparation, refining processes, improvement of the menu, better technology, increase in food allergies/intolerances, organization controls, experience of the workforce, and increased client knowledge of nutrition. The logic model demonstrated that the system is driven by policy and budget at the level of control prior to and during the planning phase but modified by the environment during operation.
Despite recognition by stakeholders on the importance of change, there are barriers to the provision of suitable food. Integration of nutrition expertise into tender documents and budgets in major event catering will help ensure nutritionally adequate, culturally suitable, and safe menus for future events.
Abstract This article aims to evaluate the quality of Brazilian school meal menus. Cross-sectional study that analyzed 2,500 menus of 500 Brazilian municipalities. The menus were evaluated based on ...the Quality Index for School Meal Menus (IQCAE - Indicador de Qualidade para Cardápios da Alimentação Escolar). The data were submitted to descriptive analysis. We found that 29,4% of menus presented high quality; 50,6%, regular quality; and 20%, low quality. Grains and tubers (86%) and Meat and eggs (67%) were the groups most found in menus, followed by Legumes (42,16%), Vegetables (40%), Fruits (35,56%), and Dairy products (18,6%); the frequency of Cured meats and sausages (8,68%) and Sweets as meals (3,64%) was lower. Among other components, 84,6% of the menus offered Sweets as dessert in none or one day a week; ultra-processed foods appear in 65,6% of menus at least once a week. In 22% of the menus, meal time was compatible with type meal served. Important food for child nutrition, such as dairy, vegetables, and fruits, are not regularly provided by school meals. Despite the advances in policy management, the presence of ultra-processed foods at least once a week is still frequent in the menus.
Resumo O objetivo deste artigo é avaliar a qualidade de cardápios escolares brasileiros. Estudo transversal analisou 2.500 cardápios, de 500 municípios brasileiros, com base no Indicador de Qualidade para Cardápios da Alimentação Escolar. Os dados foram submetidos à análise descritiva. Observou-se que 29,4% dos cardápios apresentaram alta qualidade, 50,6% qualidade regular e 20% baixa qualidade. Cereais e tubérculos (86%) e carnes e ovos (67%) foram os grupos de maior frequência nos cardápios, seguidos de leguminosas (42,16%), hortaliças (40%), frutas (35,56%) e laticínios (18,6%); a frequência da oferta de alimentos embutidos (8,68%) e doces como refeições (3,64%) foi menor. Entre os demais componentes, 84,6% dos cardápios ofertavam doces como sobremesa em nenhum ou em apenas um dia da semana; os formulados aparecem em 65,6% dos cardápios pelo menos uma vez por semana. Em 22% dos cardápios o horário estava compatível com o tipo de refeição servida. Alimentos importantes para a nutrição infantil, como laticínios, hortaliças e frutas, não são oferecidos regulamente na alimentação escolar. A despeito dos avanços observados na gestão da política, a presença de formulados pelo menos uma vez por semana ainda é frequente nos cardápios.
Large chain restaurants have reduced calories in their new menu items. No research has examined the calorie content of items eliminated from these menus.
Data are from the MenuStat project ...(2012–2015), which includes 66 of the 100 largest U.S. chain restaurants (n=27,238 items), to compare: (1) mean calories for items on the menu in all years compared with those dropped after 2012 and (2) mean calories for items new in 2013 or 2014 that stayed on the menu compared with items new in 2013 or 2014 that were dropped. The data were analyzed in 2016.
Menu items that were dropped from the menu relative to those on the menu in all years had 71 more calories (p=0.02). New items that were dropped relative to new items that stayed on the menu had 52 more calories (p=0.04).
Items dropped from chain restaurant menus are significantly higher in calories than items that remain on the menu. Eliminating higher-calorie items from restaurant menus may have a significant and positive impact on population health by reducing calorie intake without relying on individual behavior, which is very resistant to change.
While there are number of frameworks which focus on supporting the implementation of evidence based approaches, few psychometrically valid measures exist to assess constructs within these frameworks. ...This study aimed to develop and psychometrically assess a scale measuring each domain of the Theoretical Domains Framework for use in assessing the implementation of dietary guidelines within a non-health care setting (childcare services).
A 75 item 14-domain Theoretical Domains Framework Questionnaire (TDFQ) was developed and administered via telephone interview to 202 centre based childcare service cooks who had a role in planning the service menu. Confirmatory factor analysis (CFA) was undertaken to assess the reliability, discriminant validity and goodness of fit of the 14-domain theoretical domain framework measure.
For the CFA, five iterative processes of adjustment were undertaken where 14 items were removed, resulting in a final measure consisting of 14 domains and 61 items. For the final measure: the Chi-Square goodness of fit statistic was 3447.19; the Standardized Root Mean Square Residual (SRMR) was 0.070; the Root Mean Square Error of Approximation (RMSEA) was 0.072; and the Comparative Fit Index (CFI) had a value of 0.78.
While only one of the three indices support goodness of fit of the measurement model tested, a 14-domain model with 61 items showed good discriminant validity and internally consistent items. Future research should aim to assess the psychometric properties of the developed TDFQ in other community-based settings.
Foods provided in childcare services are not consistent with dietary guideline recommendations. Web-based systems offer unique opportunities to support the implementation of such guidelines.
This ...study aimed to assess the effectiveness of a Web-based menu planning intervention in increasing the mean number of food groups on childcare service menus that comply with dietary guidelines. Secondary aims were to assess the impact of the intervention on the proportion of service menus compliant with recommendations for (1) all food groups; (2) individual food groups; and (3) mean servings of individual food groups. Childcare service use and acceptability of the Web-based program were also assessed.
A single-blind, parallel-group randomized controlled trial was undertaken with 54 childcare services in New South Wales, Australia. Services were randomized to a 12-month intervention or usual care control. Intervention services received access to a Web-based menu planning program linked to their usual childcare management software system. Childcare service compliance with dietary guidelines and servings of food groups were assessed at baseline, 3-month follow-up, and 12-month follow-up.
No significant differences in the mean number of food groups compliant with dietary guidelines and the proportion of service menus compliant with recommendations for all food groups, or for individual food groups, were found at 3- or 12-month follow-up between the intervention and control groups. Intervention service menus provided significantly more servings of fruit (P<.001), vegetables (P=.03), dairy (P=.03), and meat (P=.003), and reduced their servings of discretionary foods (P=.02) compared with control group at 3 months. This difference was maintained for fruit (P=.03) and discretionary foods (P=.003) at 12 months. Intervention childcare service staff logged into the Web-based program an average of 40.4 (SD 31.8) times and rated the program as highly acceptable.
Although improvements in childcare service overall menu and individual food group compliance with dietary guidelines were not statistically significant, findings indicate that a Web-based menu planning intervention can improve the servings for some healthy food groups and reduce the provision of discretionary foods. Future research exploring the effectiveness of differing strategies in improving the implementation of dietary guidelines in childcare services is warranted.

Fast food restaurants, including top burger chains, have reduced calorie content of some menu items in recent years. However, the extent to which the nutrition profile of restaurant menus is changing ...over time is unknown.
Data from 2,472 food items on the menus of 14 top-earning burger fast food chain restaurants in the U.S., available from 2012 to 2016, were obtained from the MenuStat project and analyzed in 2019. Nutrition Profile Index scores were estimated and used to categorize foods as healthy (≥64 of 100). Generalized linear models examined mean scores and the proportion of healthy menu items among items offered in all years (2012–2016) and items offered in 2012 only compared with items newly introduced in subsequent years.
Overall, <20% of menu items were classified as healthy with no change from 2012 to 2016 (p=0.91). Mean Nutrition Profile Index score was relatively constant across the study period among all food items (≈50 points, p=0.58) and children's menu items (≈56 points, p=0.73). The only notable change in Nutrition Profile Index score or in proportion of healthy items was in the direction of menu items becoming less healthy.
At large chain burger restaurants, most items were unhealthy, and the overall nutrition profile of menus remained unchanged from 2012 to 2016. Future research should examine the nutrition profile of restaurant menus in a larger, more diverse sample of restaurants over a longer timeframe and examine whether results are robust when other measures of nutritional quality are used.
