The purpose of this paper is to assess the utility of rationalistic constructs for predicting fruit and vegetable intake in children. It was hypothesised that children's gain‐loss evaluations will predict their stage of uptake irrespective of important additional variables.

Over 200 pupils from a Derbyshire secondary school completed a cross‐sectional questionnaire assessing stages‐of‐change (precontemplation, contemplation, preparation, action, maintenance), gain‐loss considerations, prior consumption, self‐efficacy, and attitude.

Discriminant function analysis revealed self‐efficacy, attitude, and previous consumption as significant predictors of group membership for both fruit and vegetable intake. Group centroids indicated clear separation of earlier from later stages, and transitional from other stages. Gain‐loss appraisals failed to predict stage membership. Finally, 63.4 and 59.1 per cent of original grouped cases for vegetable and fruit consumption, respectively, were correctly classified. However, classification accuracy varied across stages.

The sample was predominantly Caucasian and from a suburban area. Thus, the generality of these findings to children from other demographics is unclear.

Interventions promoting fruit/vegetable intake in children may lack efficacy if they emphasise possible outcomes (e.g. benefits) associated with eating these foods. Modifying opinions and suggesting easier ways to increase consumption may achieve better results.

Previous research has demonstrated the importance of gain‐loss considerations in adult's stage of fruit/vegetable intake. The current paper extends this literature to children; it appears rationalistic constructs play a negligible role in children when considered within the context of other variables.

The purpose of this paper is to evaluate the difference in antioxidant contents of pre‐packed fresh‐cut and whole fruit and vegetables as sold in the market.

Samples of pre‐packed fresh‐cut fruit and vegetables as well as whole produce were collected from the market in Muscat and Oman, and analyzed for vitamin C, lycopene and total carotenoids. Analysis of variance was carried out to determine the level of statistical differences between fresh‐cut and whole fruit and vegetables.

In both fruit and vegetables, vitamin C contents are higher in whole than fresh‐cut produce, with greater reductions in vitamin C contents of fresh‐cut vegetables than fruit. In both fresh‐cut and whole fruit, lycopene content is 30‐36 times higher in watermelon than the contents of other fruit genotypes studied. Similarly, total carotenoids content of watermelon is six to 21 times higher than other types of fruit studied. Both lycopene and total carotenoids content are higher in whole than fresh‐cut fruit, except in pineapple fruit. In both fresh‐cut and whole vegetables, lycopene content of carrot is three to four times higher than cucumber, and four to six times higher than celery. Implications of these results on public health policy are discussed.

Previous studies on quality of fresh‐cut produce are based on controlled experimental studies using samples of produce from the same batch to compare fresh‐cut versus whole produce. However, consumers in retails stores often have to make a choice between pre‐packed fresh‐cut or whole (un‐cut) produce, which are not usually from the same source or batch. It is therefore essential to understand the differences in nutritional value of whole and pre‐packed fresh‐cuts sold in the market.

Young adults frequently engage in sub-optimal dietary behaviours, such as inadequate intakes of fruits and vegetables and excessive consumption of take-out meals. Theory-based interventions are suggested to promote dietary change. The transtheoretical model is an example that stages an individual’s readiness to change behaviours as precontemplation, contemplation, preparation, action and maintenance, and includes a series of processes that help people move between stages. The purpose of this study is to investigate whether self-reported usual dietary intakes of fruits and vegetables and take-out foods differ by reported stage-of-change.

Cross-sectional data from 250 overweight young adults, aged 18-35 years, who enrolled in a lifestyle intervention to prevent weight gain are analysed. Participant’s stage-of-change for increasing fruit and vegetable intakes and reducing take-out foods is determined using staging algorithms. This is compared with self-reported dietary intakes over the past month using a food frequency questionnaire. Differences in intakes and variety by stage-of-change are compared for fruits, vegetables and take-out foods.

Take-out foods differed between stages (p < 0.0001), with lower weekly intakes in action (309 g) and maintenance (316 g) compared with preparation (573 g). Daily fruit intakes and variety scores varied by stage-of-change (p < 0.0001), being highest for action and maintenance (261 g and 263 g, respectively, and variety scores of 1 and 2) compared with precontemplation, contemplation and preparation (all = 100 g and 0 for variety). Daily vegetable consumption and variety scores differed by stage (p = 0.009 and p = 0.025, respectively) being highest for action/maintenance (204 g and 2 for variety) versus precontemplation and preparation (<110 g daily and Variety 1).

The finding of no differences in intakes between precontemplation, contemplation or preparation stages implies that the adoption of the dietary behaviours is not a continuum but a move from pre-action to actioning the target intakes. This means that for planning health promotion and dietary counselling, assigning people to the three different pre-action stages may be unnecessary.

This study is the first to examine the congruence of self-reported readiness to change behaviour with dietary intakes of take-out foods as well as variety of fruit and vegetables in overweight young adults.

The purpose of this paper is to investigate the effects of the Cancer Society of Lower Saxony’s school-based nutrition education programme “5-a-day for kids”, designed to increase children’s fruit and vegetable consumption. Intervention: the programme included three parts (each 45 minutes): education-based classroom session; food knowledge in a local supermarket; and practical vegetable snack preparation. Additional promoting information materials for parents were provided.

A pre-/post-test research design was used for the evaluation. In total, 1,376 pupils (age 7-14, 51 per cent female), their parents and 69 teachers of 35 schools in Lower Saxony participated in the study. The fruit and vegetable intake was measured with the KiGGS-Food Frequency Questionnaire.

A Wilcoxon signed-rank test was used to determine the change in fruit and vegetable consumption over three measurements (baseline, one month, three months). No significant positive effect of the intervention was observed with the applied method for the daily intake of fruit and vegetables, neither at month 1 nor at month 3.

A 135 min school-based intervention does not seem to increase children’s fruit and vegetable consumption. To enhance its effectiveness, the programme may be improved by adding a longitudinal classroom component, extensive parental involvement and/or distribution of free fruit/vegetables every day.

This is the first evaluation of a 5-a-day-intervention in Germany.

The study assessed the levels of organochlorine pesticides (OCPs) and their potential non-carcinogenic and carcinogenic health risks in four regularly consumed fruit vegetables.

The OCPs’ residues were quantified using a gas chromatograph coupled with an electron capture detector (GC-ECD) and the dietary exposure of children, and adult consumers to the detected OCPs was evaluated using carcinogenic and systemic health risk estimations.

Aldrin, endrin, endrin aldehyde, a-endosulfan, β-endosulfan, endosulfan sulphate, heptachlor, heptachlor epoxide and dieldrin were detected in the four fruit vegetables. The predominant OCP residue in carrot, cucumber, tomatoes and watermelon was endosulfan sulphate with mean concentrations of 2.532 mg kg⁻¹, 1.729 mg kg⁻¹, 2.363 mg kg⁻¹ and 1.154 mg kg⁻¹, respectively. The residues levels in some of the fruit vegetables were higher than their respective maximum residue levels (MRLs) of 0.01–0.05 mg kg⁻¹ set by the European Commission with concentrations above MRLs ranging between 25.5% and 100%. The systemic health risk estimations showed that the hazard index (HI) values for carrot (3.20), cucumber (9.25), tomatoes (50.21) and watermelon (16.76) were >1 for children consumers and the respective HI values of 2.87, 15.57 and 5.20 for adult consumers of cucumber, tomatoes and watermelon were >1 which implies potential systemic health risks. Four carcinogens (aldrin, dieldrin, heptachlor and heptachlor epoxide) had cancer risk index values greater than the acceptable risk of 1 in 1 million for both adult and children consumers.

The paper shows that despite the ban on the use of OCPs in Nigeria, they are still being used for agricultural production especially on some locally produced and regularly consumed fruit vegetables as reported in the present study. The non-existence of surveillance programmes on pesticide usage and the lack of proper monitoring of pesticide residues in food products including fruit and vegetables must have contributed to the levels of the detected OCP in the samples analysed. The current daily intake of OCP via contaminated vegetables may pose potential health risks to both the children and adult consumers of the fruit vegetables.

The present paper explores Generation Z university students' clusters based on the consumption of daily fruits and vegetables in an emerging market economy, indicating young people's reasons to adopt a healthy diet.

Using cluster theory, the authors analyse Generation Z university students who consume fresh fruits and vegetables, highlighting aspects of a healthy diet, in compliance with the WHO recommendations and challenges.

Data collected from over 459 Generation Z university students point out the possibility of typologizing them into nine clusters: three consuming fresh fruit and six consuming fresh vegetables. Most cluster members are aware of the value of regular fresh fruit and vegetable consumption in order to maintain health and overall well-being, but the authors also identified a cluster called “urban, but sick humanists at the beginning of their professional careers”, for whom a healthy diet based on fruits and vegetables is not a priority.

Although this research only refers to consumers in the emergent economy Romania, it also allows the delimitation of specific categories which can be utilized by sector stakeholders, in order to identify issues addressed by each cluster member and to find the most appropriate solutions for encouraging/promoting a healthy diet.

The paper also raises awareness of the importance of fruit and vegetable consumption in other emerging economies, given the advancement of processed food and reduction of time available to cook healthy dishes.

The results contribute to extending studies conducted on emerging markets concerning fruit and vegetable consumption among Generation Z university students, highlighting the importance of a healthy diet, and the proper targeting of these consumer clusters by fresh fruit and vegetable producers and distributors.

The purpose of this paper is to evaluate the evidence base of the Food Dudes healthy eating programme, specifically the short- and long-term effectiveness of the intervention for consumption of fruit and vegetables both at school and at home and displacement of unhealthy snack consumption.

Articles were identified using Academic Search Complete, PsycARTICLES, Medline and PubMed databases keywords for the period January 1995 to August 2013. Articles were included if they reported an empirical evaluation of the Food Dudes programme aimed at children aged between 4-11 years. Articles were included regardless of geographical location and publication type (i.e. published and “grey” literature).

Six articles were included for review. Findings indicated that the programme was moderately effective in the short term; however, the long-term effectiveness of the programme is unknown. The ability of the programme to generalise to the home setting and to displace unhealthy snack foods also requires further investigation.

This is the first independent review of the Food Dudes programme. In light of the extensive roll out of the Food Dudes programme, an appraisal of the evidence surrounding the programme is timely. The review highlights that sustaining fruit and vegetable intake cannot be achieved through behaviour-based interventions alone and the long-term maintenance of fruit and vegetable consumption requires more than the implementation of an intervention found to be effective in a controlled research environment.

The purpose of this paper is to assess the influence of availability of fruits and vegetables on adult workers' consumption adequacy in the workplace.

A total of 1,344 workers, who have had meals in 30 different companies, located in the city of São Paulo, Brazil, are assessed. Two indicators are used to assess the following: workers' consumption of fruits and vegetables; usual consumption, found through a questionnaire on frequency of consumption of these foods; and workplace consumption, assessed with a food consumption questionnaire provided by the company. Availability of fruits and vegetables in the menus is obtained using the descriptions of meals given to workers on three consecutive days. Data analysis is performed with logistic regression models that used two outcomes: usual consumption of fruits and vegetables and consumption of these foods in the workplace. Explanatory variables are divided into two levels: the first one was comprised by workers' characteristics (sex, age and level of education), and the second one by food availability in the workplace.

Consumption of fruits and vegetables, both the usual one and that in the workplace, is higher in women, and also in older individuals and those with higher level of education. Availability of fruits and vegetables in the workplace has a significant impact on usual food consumption and especially on the workplace, in which case the variable shows greatest impact on consumption.

This study demonstrates the importance of the availability of fruits and vegetables in the workplace that influence consumption of food by workers, revealing the importance of using this environment to promote healthy eating.

The purpose of this paper is to fill a knowledge gap by examining the changes in fruit and vegetable consumption of Chinese households.

Using 1993 and 2001 household survey data from three selected provinces in China, the authors estimated a quantile regression (QR) model to demonstrate how changes of fresh fruit and vegetable consumption over time may differ across regions, and additionally, how these changes may differ over the entire distribution.

Results show significant increases in fresh fruit consumption for all provinces; in addition, the pattern of changes over time differs across the entire distribution. In contrast, significant decreases of fresh vegetable consumption are evident, and results are robust across regions; however, the disparities of fresh vegetable consumption across regions are not significant.

The results may shed some light on the national food policy. First, any food policy that may affect prices of fresh fruits and vegetables will likely affect households in lower percentiles more than those in upper percentiles. In addition, based on the findings, households in Guangdong may have a higher risk of inadequate fruit consumption. Lower level consumption of fruits in Guangdong may be caused by its relatively high prices of fruits and perhaps the shifting consumption pattern to a more meat‐based diet as income increases.

There has been considerable interest in estimating food demand structure in China due to its huge market for food products. However, little is known about the fruits and vegetables products. In addition, most of the previous studies used the linear regression‐type model for analysis, which fails to capture the effects of the exogenous factors on the entire distribution. To fill the knowledge gap, this paper uses a QR model with the different‐in‐difference method to examine the changes in fruit and vegetable consumption of Chinese households.

The purpose of this paper is to explore primary school children’s beliefs towards eating fruit and vegetables in a deprived area in England.

Semi-structured interviews were conducted with 11 children aged 9-11 from an after school club at a primary school in a deprived area in the West Midlands. Interviews were analysed using inductive thematic analysis.

Six master themes emerged from the data: “effect on the senses”, “feelings about food”, “healthy vs unhealthy foods”, “effects on health”, “convenience” and “family and friends”. Analysis showed that children seemed to have a very good awareness of the health benefits of eating fruit and vegetables. However, negative beliefs were associated with sensory perceptions (such as taste, texture, appearance and aroma), availability, and the competing desirability of other, unhealthy foods. Also, although parents were key influences, siblings and friends were often perceived as negative influences and would tease children about eating fruit and vegetables.

Suggestions for interventions include increasing the appeal and availability of pre-prepared fruits and vegetables in both home and school environments. Additionally, an approach to eating more fruit and vegetables which focusses on siblings and friends is advocated as these groups appear to play a key role in terms of promoting the consumption of these foods.

This study is novel as it uses individual interviews to explore primary school children’s attitudes towards fruit and vegetable consumption in a deprived area in England. By focussing on the specific behaviours of fruit and vegetable consumption, the findings aid the development of interventions that are designed to improve children’s healthy eating behaviour.
