Abstract

Purpose

The purpose of this paper is to describe the results of the construct validity by the known-groups method of a Brazilian cooking skills and healthy-eating questionnaire.

Design/methodology/approach

Responses obtained from university students (n=767) for Brazilian-Portuguese cooking skills and health eating questionnaire, surveyed online, were submitted to construct validity comparing two known groups. The t-test was used to compare differences between gender (male and female) and the level of cooking knowledge (high or low) in each measure of the questionnaire. Internal consistency was evaluated by obtaining the Cronbach’s coefficient.

Findings

Women showed significantly higher means than men in all scale measures, except in the self-efficacy for using basic cooking techniques (SECT), where no differences were found. Students classified as having high cooking knowledge and had higher score means in all scales compared to the students with low levels. Internal consistency was adequate for all scales (a>0.70), except for cooking attitude (CA) (a=0.33) and cooking behavior (CB) scales (a=0.59).

Research limitations/implications

SECT likely depends on cooking knowledge, independent of gender, suggesting further examination. Items and structure of CA and CB constructs also need to be examined more deeply.

Practical implications

A validated cooking skills and health-eating questionnaire demonstrated its ability to detect differences between groups, useful to provide data for further interventions.

Originality/value

No available cooking skills questionnaires were found that have been validated by the known-groups method regarding differences between gender and individuals’ level of cooking knowledge, as conducted in this study.

Abstract

Purpose

The World Health Organization recommends limiting the intake of free sugars, which can be added to packaged foods and may appear on labels under different terms. The aim of this research was to analyse the evidence related to the declaration of free sugars from fruits on packaged food labels.

Design/methodology/approach

A scoping review was conducted following the recommendations of the Joanna Briggs Institute (JBI).

Findings

Ten eligible studies, conducted in seven countries, were included in this review. The percentage of packaged foods in which free sugars were identified ranged from 52.5 to 86.5%. In three studies, terms related to sugars were identified inductively by reading the entire ingredient list, whereas in the other studies sugars were identified by searching for a list of predefined terms. Studies differed in the definition of sugars and the terms used to identify them. Nine studies included fruit sugars within the terms used to identify free sugars. However, they lacked consistency in the types of fruit sugars considered and did not discuss their agreement with the adopted definitions of sugars.

Originality/value

As far as can be ascertained, this is the first review that addresses the declaration of free sugars from fruits on packaged food labels. Overall, there is a scarcity of literature focused on identifying and discussing the range of free sugars from fruits declared on food labels.

Abstract

Purpose

The purpose of this paper is to compare the trans fatty acids (TFA) content in foods before and after the implementing of the method for controlling trans fatty acids in meals (MCTM) in a Brazilian restaurant.

Design/methodology/approach

Analysis by gas chromatography was performed on 49 processed foods used as ingredients for culinary preparations (42 and seven samples before and after the implementation of the method, respectively) and 57 prepared foods (31 and 26 samples before and after the implementation of the method, respectively). In addition, the meal preparation process was monitored before the implementation of the MCTM method in order to identify the changes resulting from its application.

Findings

As a result of the application of the method the processed foods whose labels reported the presence of ingredients potentially containing industrial trans fat acids (iTFA) were not purchased and used in food preparations; standard recipes prepared with processed foods free of iTFA were implemented; and also the restaurant’s staff were trained to control the frying process for preparing fried foods. The average content of TFA per 100 g of prepared food was 0.21 g less (p=0.038) after the implementation of the method.

Practical implications

The MCTM method showed to be a viable and effective tool for reducing TFA levels in the studied restaurant.

Originality/value

The developed method is original since no similar tool for controlling of TFA in food services has been found in the scientific literature. The fatty acid profile determination in the meals prepared after the MCTM implementation showed a reduction in TFA, indicating that the method was also viable and efficient.

Abstract

Purpose

Adequate vegetable consumption is fundamental to a healthy balanced diet; however, global compliance with recommendations is poor which is particularly important for young adults as they form food consumption habits. There is a growing interest in the circular economy of hospitality and sustainability of current dietary patterns in light of climate change and an expanding global population. The food value chain needs to be considered both vertically and horizontally where the research and development (R&D) investment is optimised by being “joined up” and not fragmentary; in addition, consumer trade-offs of health vs for example sensory appeal are taken into consideration. The purpose of this study was to identify factors predicting acceptance of vegetable dishes by young adults and present a roadmap that can be used for dish development and healthful marketing.

Design/methodology/approach

This study used the health belief model (HBM) as framework to investigate key factors that encourage vegetable intake by young adults using an online questionnaire sample of 444 enrolled in undergraduate programs at universities in Brazil.

Findings

Structural modelling showed that vegetable consumption frequency was positively influenced by Health concerns, Naturalness and Self-efficacy (including cooking skills), whereas Sensory factors and Familiarity demonstrated a negative loading that might be related to unpleasantness.

Originality/value

Globally, there is a strong need to promote the consumption of vegetables as a public health policy priority but also to ameliorate barriers to action that could be facilitated by availability, dish development and healthful marketing in hospitality operations.

Abstract

Purpose

This study aimed to examine the perceptions and preferences of Brazilian adult consumers about four different front-of-pack (FOP) food labeling systems proposed by the Brazilian National Health Regulatory Agency.

Design/methodology/approach

This is a qualitative study conducted with 33 participants allocated in six focus groups. Four different types of FOP labels were displayed on processed and packaged bread: three interpretive warning labels (black triangle, black octagon and red ellipse) and a hybrid model (nutritional traffic light). Thematic analysis was used to identify the key topics addressed by participants.

Findings

Three topics were identified: label design, clarity and precision of information. The results demonstrated an influence of labels on product development and consumers' food choices. Most participants expressed a preference for black warning labels and reported the importance of statements endorsed by the Ministry of Health, which provide credibility and could influence food choices. Furthermore, participants agreed that the traffic light system provides more information but is difficult to interpret when comparing products. Warning labels were reported to have the greatest influence on purchase decisions. However, participants were concerned about how to understand the lack of warning labels on some products.

Practical implications

The results may help and support the Brazilian Health Regulatory Agency to identify and recommend the most effective FOP labeling system to be adopted in Brazil.

Originality/value

Few studies investigating adult consumers' perceptions of different FOP label formats have been conducted in the Brazilian context. Our study contributes to the small pool of evidence on the topic by demonstrating that FOP labels can be helpful for consumers when they are presented in an intuitive, interpretative and trustworthy format.

Abstract

Purpose

Self-efficacy in cooking and consuming fruits and vegetables is one of the dimensions that compose cooking skills. This cross-sectional study aimed to assess the self-efficacy of Brazilian university students in cooking and consuming fruits and vegetables and examine the relationship of self-efficacy with sociodemographic and lifestyle characteristics.

Design/methodology/approach

Data were collected through an online questionnaire, which was culturally adapted and validated for the studied population. Questions about self-efficacy for using basic cooking techniques (SECT), self-efficacy for using fruits, vegetables, and seasonings (SEFVS) and produce consumption self-efficacy (SEPC) were rated on a five-point Likert scale. Differences in median self-efficacy score between groups were compared using the Mann–Whitney U test or the Kruskal–Wallis test followed by the Mann–Whitney U test.

Findings

766 subjects participated in the study. The mean age was 21 ± 5.6 years, most respondents were female (60%), reported to know how to cook (72%), and lived with parents and/or grandparents (45%). The median SECT and SEFVS scores were 3.55, and the median SEPC score was 3.33. Female students, individuals aged more than 25 years, and students who did not live with their parents or grandparents had higher (p < 0.005) self-efficacy scores. Low SECT, SEFVS and SEPC scores were associated with having less than one hour a day to cook (p = 0.023, 0.01, and 0.002, respectively) and not knowing how to cook (p < 0.001). There was no relationship of median self-efficacy scores with source of knowledge about cooking skills or parental education.

Originality/value

The results of this study can guide interventions and public policies aimed at health promotion in the university setting.

Abstract

Purpose

The purpose of this paper is to examine the effects of different menu labelling formats on healthy food choices in a real restaurant setting.

Design/methodology/approach

This cross-sectional, randomised and controlled parallel-group trial was conducted in Brazil in 2013. In total, 313 university students were randomly assigned to one of three parallel groups with different menu labelling formats. Of these, data from 233 students were analysed. The others did not attend and were excluded. Intervention Group 1 (n=88) received information in the form of a traffic light plus guideline daily amounts, while Intervention Group 2 (n=74) was presented with ingredients list plus highlighted symbols (IL+S). The control group (n=71) received a menu with no menu labelling. Data were collected on one weekday in a restaurant setting. Trial outcomes were assessed by healthy food choices.

Findings

Healthy food choices of students who received the menu showing IL+S were significantly higher when compared to the other groups. This same menu labelling format positively affected healthy food choices in women, not overweight participants and in participants who often ate out more than twice a week.

Originality/value

Menu labelling format presenting ingredients list and highlighted symbols was positively associated with healthy food choices among the university students in Brazil. This type of labelling could be adopted in future legislation on menu labelling in Brazil and around the world.

Abstract

Purpose

The purpose of this paper is to relate average serving size intake by the Brazilian population and declared serving size, the presence of trans fat and household measure fractioning declared on labels of processed, and ultra-processed food products.

Design/methodology/approach

Cross-sectional study that analyzed the food labelling of all processed and ultra-processed food products sold in a supermarket in southern Brazil.

Findings

A total of 1,071 processed and ultra-processed food products were analyzed. In 88 per cent of food groups, the average serving size consumed was larger than what was declared on labels. Consumed serving size was up to 9.2 times larger than the declared ones in food products with trans fat among their ingredients list and in false negatives and up to 9.9 times larger in foods with fractioned household measure (p<0.001). The Brazilian population consumes, on average, larger serving sizes than those declared on labels, which may represent a significant intake of trans fats without the consumers’ noticing.

Originality/value

This study has been performed with the use of a national database on food consumption, as well as the information from a large number of processed and ultra-processed food labels marketed in Brazil. This study is also proven to be important and novel, contributing with information as to the manner in which nutrition labelling has been presented to Brazilian consumers, discussing its possible consequences for food choices, intake, and the guarantee of consumer rights.

Abstract

Purpose

The potential for the foodservice industry to be part of a public health strategy has led to a new understanding of this sector’s role in a wider interdisciplinary health environment. The purpose of this paper is to evaluate the influence of the foodscape on fruit and vegetable choice by staff in a higher educational setting.

Design/methodology/approach

Foodscape mapping of fruit and vegetable provision on campus was conducted to provide context. Two focus groups with staff and two interviews with foodservice managers took place to gain depth of understanding. Thematic analysis was conducted to allow for pattern and meaning to emerge.

Findings

Results demonstrate two main overarching themes; personal influence and food operator influence that impact on fruit and vegetable choice. In addition connectivity, perceptions of freshness, food quality and display seemed to be strong categories emerging from the data. Interestingly, this research indicated that consumers were more likely to eat fruit and vegetables when part of a composite dish than if served separately.

Practical implications

Providing a positive foodscape to enhance availability of fruit and vegetables may be challenging but helpful towards health promotion. Nevertheless, no “nudging” can control choice made by individuals, responsibility for healthy selection must always remain personal.

Originality/value

Knowledge gained by this pilot study will add to the body of literature and evidence base for further research while contributing to foodservice strategies which may promote increased fruit and vegetable consumption.

– The purpose of this paper is to present a first proposal of a healthy dietary diversity index to evaluate meals in self-service restaurants.

Abstract

Purpose

The purpose of this paper is to present a first proposal of a healthy dietary diversity index to evaluate meals in self-service restaurants.

Design/methodology/approach

This was a cross-sectional, descriptive pilot study in a Brazilian buffet-style restaurant. The study group was selected by systematic sampling and consisted of 678 individuals aged 16-81 years, who were regular diners at a selected restaurant during lunchtime. Photographs were used to assess food choices and a sociodemographic questionnaire was administered to the subjects. A healthy dietary diversity model was created following WHO recommendations and the Brazilian Food Guide. A consensus workshop was conducted with experts to discuss and classify certain dishes as more or less healthy (high/low energy density). The model attributed negative (−3.0-0.0) and positive (0.0-12.0) scores to different food groups. Higher scores meant greater diversity on the plate, and therefore a greater chance of a healthy meal (=9.0), while a lower score reflected a higher variety of energy-dense foods, such as fried dishes (=6.0).

Findings

Most diner’s plates (65.3 per cent) obtained low diversity score indexes (=6) and were considered inadequate, represented the dishes where intake should be controlled from a nutritional viewpoint (over caloric meal). There was a significant association between healthy diversity scores (=9.0) and low variety of high energy density dishes on the plates.

Originality/value

This method of assessing the healthy dietary diversity of a main meal could be tested as an innovative model for investigating the food choices of individuals who eat away from home.
