Abstract [en]

Since food waste valorisation measures, like energy recovery, have limited possibilities to fully recover the resources invested in food production, there is a need to prevent food waste. Prevention is most important at the end of the value chain, where most sub-processes have already taken place, like in catering facilities. In Sweden, the public catering sector serves a large number of meals through municipal organisations, including schools, preschools and elderly care homes. Many of these organisations quantify food waste, but since Sweden has 290 municipalities with a high degree of independence, the possible variation is significant. This study therefore investigated how food waste is quantified, in order to help formulate a national standard for food waste quantification.

Mapping of food waste quantification practices was conducted using a questionnaire and follow-up telephone calls, achieving a response rate of 93%. Of the 290 Swedish municipalities, 55% replied that they quantify food waste on central level. The most common practice at present is to quantify plate- and serving waste from school lunches during two weeks per year, and to compile waste data in spreadsheets and compare the values against the number of plates used, giving a result in grams per portion served. There are many similarities between municipalities, so there is great potential to implement a common standard that many municipalities already fulfil. This is important in order to gain acceptance and fast implementation, thereby speeding up the process of establishing a benchmark for food waste in the Swedish public sector catering sector.

Abstract [en]

The Child Eating Behaviour Questionnaire (CEBQ) is a well-established instrument in the study of obesity-relatedeating behaviours among children. However, research using the CEBQ in multicultural samples is limited. This studyaims to identify and examine differences in child eating behaviours as reported by Swedish-born and non-Swedishbornmothers living in Sweden. Mothers (n=1310, 74 countries of origin, mean age 36.5 years, 63.6% with highereducation, 29.2% with overweight or obesity) of five-year-olds (mean age 4.8 years, 18.1% with overweight or obesity)completed the CEBQ. Responses were analysed using CEBQ subscales Food Responsiveness, EmotionalOvereating, Enjoyment of Food, and Desire to Drink, clustering into Food Approach, and subscales SatietyResponsiveness, Slowness in Eating, Emotional Undereating, and Food Fussiness, clustering into Food Avoidance.Data were compared across seven regional groups, divided by maternal place of birth: (1) Sweden (n=941), (2) Nordicand Western Europe (n=68), (3) Eastern and Southern Europe (n=97), (4) the Middle East and North Africa (n=110),(5) East, South and Southeast Asia (n=52), (6) Sub-Saharan Africa (n=16), and (7) Central and South America (n=26).Crude, partly and fully adjusted linear regression models controlled for child’s and mother’s weight status, age,mother’s education, and concern about child weight. The moderation effect of maternal concern about child weightwas examined through interaction analyses. Results showed that while Food Approach and Food Avoidancebehaviours were associated with maternal migrant background, associations for Food Fussiness were limited. Notably,mothers born in the Middle East and North Africa reported higher frequencies of both Food Approach (except forEnjoyment of Food) and Food Avoidance. The study highlights the importance of examining how regionally-specificmaternal migrant background affects mothers’ perceptions of child eating behaviours.

Abstract [en]

Purpose

The purpose of this paper is to explore how stakeholders in the food and nutrition field construct and conceptualise “appropriate” national dietary advice.

Design/methodology/approach

In total, 40 voluntarily written stakeholder responses to updated official dietary guidelines in Sweden were analysed thematically. The analysis explored the logics and arguments employed by authorities, interest organisations, industry and private stakeholders in attempting to influence the formulation of dietary guidelines.

Findings

Two main themes were identified: the centrality of anchoring advice scientifically and modes of getting the message across to the public. Stakeholders expressed a view of effective health communication as that which is nutritionally and quantitatively oriented and which optimises individuals’ capacities to take action for their own health. Their responses did not offer alternative framings of how healthy eating could be practiced but rather conveyed an understanding of dietary guidelines as documents that provide simplified answers to complex questions.

Practical implications

Policymakers should be aware of industrial actors’ potential vested interests and actively seek out other stakeholders representing communities and citizen interests. The next step should be to question the extent to which it is ethical to publish dietary advice that represents a simplified way of conceptualising behavioural change, and thereby places responsibility for health on the individual.

Originality/value

This research provides a stakeholder perspective on the concept of dietary advice and is among the first to investigate referral responses to dietary guidelines.

Abstract [en]

Food waste in the food services industry has been identified as an important unsustainability hotspot, but standardised methods for food waste quantification are lacking. Existing studies on waste quantity assessments have several limitations, such as short and infrequent quantifications times, large methodological variations ranging from physical measurements to visual observations, and lack of comparability across catering unit types. Since lack of comparable waste figures can lead to error-prone analysis, a general framework is needed for waste quantification in food services. This paper presents one such framework that allows data comparisons when overlapping observations are included. The framework was tested in six case studies in professional (public and private) catering units in Sweden. Data were collected from different schools, elderly care homes and hotels and fitted into the framework. The results from these case studies indicate that the framework enables catering units to focus waste quantification on their individual problem areas. It also provides the possibility to extend waste quantification over time without any loss of generalisability. A graphical representation of the framework fits the traditional tree structure and was found to act as a suitable foundation for food waste quantification in food services by structuring collected data. In order to fully utilise the potential of the tree structure, it should be supplemented with precise definitions to create a catering food waste quantification standard.

Abstract [en]

Aims: School lunches are provided free in Sweden, although some children choose not to eat school lunch. The aim of this study was to analyse Swedish children's total energy and nutrient intakes on weekdays by the frequency of school lunch consumption and to analyse energy and nutrient intakes from school lunches by sex. Factors associated with children's school lunch habits were also studied. Methods: Children in grades 2 and 5 (n=1905) completed a food diary (school lunch data available for 1840 children) and the mean energy and nutrient intakes per day and per school lunch were calculated. The children also completed questions on the frequency of school lunch consumption and school lunch habits. Logistic regression was used to assess factors associated with school lunch habits. Results: Children who reported eating school lunch every day had significantly higher energy and absolute nutrient intakes than children reporting eating school lunch less than five times a week, but not standardized for energy. Boys had significantly higher energy and absolute nutrient intakes from school lunches than girls, but not standardized for energy. Younger children and children who liked school lunches had higher odds of eating school lunch every day. Children in grade 5, those with a foreign background and those disliking school lunches had higher odds of omitting the main lunch component. Conclusions: Regular school lunch consumption was associated with a higher total intake for most nutrients, but not a better nutrient density. School lunch habits were associated with age, ethnic background and liking school lunches.

Abstract [en]

National Dietary Guidelines have been published in many countries to support healthier food habits among the public. In Sweden, the guidelines are produced in a process involving experts and stakeholders under the responsibility of the National Food Agency. Stakeholder perspectives on the concept of state dietary advice was explored in this study, by analyzing 40 referral responses on updated guidelines in Sweden 2015. The study focused on ideas about how state dietary advice should be framed and what it should be based on. Thematic analysis was used and resulted in two main themes. 'Securing scientifically proven advice' represented a perspective of the guidelines as to be scientifically correct and verified, and built upon an underlying assumption to present an objective and optimal composition of foods and nutrients that will fit all. Arguments based on nutritional reductionism could be seen, which gave a delimited idea of what healthy food is. 'Getting the message across' represented a perspective of the guidelines to be easily understood by and inclusive to the end user. Clarity in advice was seen to be reached by explaining difficult words, defining amounts and exact mechanisms of why something is a good choice. Also this perspective added to excluding other values of food, especially qualitative ones. The construction of a healthy diet in these remittance responses builds upon a notion of an ideal diet composed on the basis of the best scientific proof and clearly presented so as to be easily understood and practiced. It was clearly based on an individualistic behavioral view making the individual responsible to make informed and good choices for a healthy diet. This approach may be questioned, as it is too simplified to include the complex reality of everyday life.

Abstract [en]

Food waste is a major problem that must be reduced in order to achieve a sustainable food supply chain. Since food waste valorisation measures, like energy recovery, have limited possibilities to fully recover the resources invested in food production, there is a need to prevent food waste. Prevention is most important at the end of the value chain, where the largest number of sub-processes have already taken place and occur in vain if the food is not used for its intended purpose, i.e. consumption. Catering facilities and households are at the very end of the food supply chain, and in Sweden the public catering sector serves a large number of meals through municipal organisations, including schools, preschools and elderly care homes. Since the first step in waste reduction is to establish a baseline measurement in order to identify problems, this study sought to quantify food waste in schools, preschools and elderly care homes in one municipality in Sweden. The quantification was conducted during three months, spread out over three semesters, and was performed in all 30 public kitchen units in the municipality of Sala. The kitchen staff used kitchen scales to quantify the mass of wasted and served food divided into serving waste (with sub-categories), plate waste and other food waste. The food waste level was quantified as 75 g of food waste per portion served, or 23% of the mass of food served. However, there was great variation between kitchens, with the waste level ranging from 33 g waste per portion served (13%) to 131 g waste per portion served (34%). Wasted food consisted of 64% serving waste, 33% plate waste and 3% other food waste. Preschools had a lower waste level than schools, possibly due to preschool carers eating together with the children. Kitchens that received warm food prepared in another kitchen (satellite kitchens) had a 42% higher waste level than kitchens preparing all food themselves (production units), possibly due to the latter having higher flexibility in cooking the right amount of food and being able to chill and save surplus food. The large variation between kitchens indicates that they have different causes of food waste, but also different opportunities to reduce it. Detailed waste quantification for each kitchen can therefore be the first step in the process of waste reduction.
