Konferensbidrag (refereegranskat)abstract
- Food and meals are central elements in our lives: a source of pleasure, a social activity and a bearer of culture. Our eating habits are also very important to health, which implies that the organization and content of meals is a prerequisite for well-being and learning. Schools, in particular, have unique opportunities to promote healthy lifestyles, help develop good eating habits and raise environmental and climate awareness among children and youths by embedding food in a wider context. Unsurprisingly, there is also an increasing interest in school meals and food-related education among researchers, many of whom agree that the quality of school meals can be seen as one of the most accurate indicators of the cities’ sustainability potential. Systematic quality work, however, requires shared targets and ambitions, regular quality checks and discussions on development and improvement. In that vein, the City of Gothenburg has launched the project Urban Rural Gothenburg, which assembles, develops, tests and implements new solutions for the city’s public kitchens. This involves climate-smart and environmentally sound perspectives and programs regarding meal planning, food procurement, food preparation and food-related teaching and learning. One important approach deals with the normalization of increased vegetarian consumption and greater awareness of food’s origins and travel from farm to table. Another approach deals with conscious choices of raw materials that are beneficial for both the environment and health. A third notable approach focuses on new ways of handling food waste to reduce climate impact. In line with the third Sustainable Development Goal, this presentation captures and reaffirms the fundamental assumptions and methods involved in Gothenburg’s work with food sustainability in public kitchens, with an emphasis on health and climate as cross-cutting issues that matter to us all.

Tidskriftsartikel (refereegranskat)abstract
- This article arises from an interest in African urbanization and in the food, farming and nutritional transitions that some scholars present as integral to urban life. The paper investigates personal urban food environments, food sources and access strategies in two secondary Ugandan cities, Mbale and Mbarara, drawing on in-depth interviews and applying an intersectional lens. Food sources were similar across dimensions of difference but food access strategies varied. My findings indicate that socioeconomic circumstance (class) was the most salient influence shaping differences in daily food access strategies. Socioeconomic status, in turn, interacted with other identity aspects, an individual’s asset base and broader structural inequalities in influencing urban food environments. Rural land and rural connections, or multispatiality, were also important for food-secure urban lives. The work illuminates geometries of advantage and disadvantage within secondary cities, and highlights similarities and differences between food environments in these cities and Uganda’s capital, Kampala.

- OBJECTIVE: Many studies of food intake have been performed and published in Sweden, but to our knowledge no studies have extensively explored the beverage consumption of the Swedish adult population. The present study aimed to describe the beverage consumption and the contribution of beverage energy (including alcohol energy) to total energy intake according to gender, region of living, meal type and day for a Swedish adult population.DESIGN: National dietary survey Riksmaten (2010-2011), collected by the Swedish National Food Agency.SETTING: Sweden.SUBJECTS: A total of 1682 participants (57 % women) reported dietary intake data during four consecutive days, specified by portion size, meal, time point, day of the week and venue. Meals were categorized as breakfast, lunch, dinner and 'other'.ResultThe beverage reported to be consumed the most was water (ml/d), followed by coffee. Men had a higher consumption of juice, soft drinks, beer, spirits and low-alcohol beer, while the consumption of tea and water was higher for women. For both genders, milk contributed the most to beverage energy intake. Energy percentage from beverages was higher at lunch and dinner during weekends for both genders. Participants from the biggest cities in Sweden had a higher consumption of wine for both genders and tea for men than participants from other regions.CONCLUSIONS: A considerable part of total energy intake was contributed by beverages, especially for men. Beverages can contribute to a more enjoyable diet, but at the same time provide energy, sugar and alcohol in amounts that do not promote optimal health.

Rising rural body-mass index is the main driver of the global obesity epidemic in adults
- 2019

Tidskriftsartikel (refereegranskat)abstract
- Body-mass index (BMI) has increased steadily in most countries in parallel with a rise in the proportion of the population who live in cities(.)(1,2) This has led to a widely reported view that urbanization is one of the most important drivers of the global rise in obesity(3-6). Here we use 2,009 population-based studies, with measurements of height and weight in more than 112 million adults, to report national, regional and global trends in mean BMI segregated by place of residence (a rural or urban area) from 1985 to 2017. We show that, contrary to the dominant paradigm, more than 55% of the global rise in mean BMI from 1985 to 2017-and more than 80% in some low- and middle-income regions-was due to increases in BMI in rural areas. This large contribution stems from the fact that, with the exception of women in sub-Saharan Africa, BMI is increasing at the same rate or faster in rural areas than in cities in low- and middle-income regions. These trends have in turn resulted in a closing-and in some countries reversal-of the gap in BMI between urban and rural areas in low- and middle-income countries, especially for women. In high-income and industrialized countries, we noted a persistently higher rural BMI, especially for women. There is an urgent need for an integrated approach to rural nutrition that enhances financial and physical access to healthy foods, to avoid replacing the rural undernutrition disadvantage in poor countries with a more general malnutrition disadvantage that entails excessive consumption of low-quality calories.

Tidskriftsartikel (refereegranskat)abstract
- This article contributes to a feminist geographic analysis of how urban food and health environments and non-communicable disease experience may be being constructed, and contested, by healthcare professionals (local elites) in two secondary Ugandan cities (Mbale and Mbarara). I use thematic and group interaction analysis of focus group data to explore material and discursive representations. Findings make explicit how healthcare professionals had a tendency to prescribe highly classed and gendered assumptions of bodies and behaviours in places and in daily practices. The work supports the discomfort some have felt concerning claims of an African nutrition transition, and is relevant to debates regarding double burden malnutrition. I argue that a feministic analysis, and an intersectional appreciation of people in places, is advantageous to food and health-related research and policy-making. Results uncover and deconstruct a dominant patriarchal tendency towards blaming women for obesity. Yet findings also exemplify the co-constructed and malleable nature of knowledge and understandings, and this offers encouragement.

Tidskriftsartikel (refereegranskat)abstract
- Little is known about the relationships between weight satisfaction, body image concern, healthy nutrition, health awareness, and physical activity among college students across culturally different countries. We assessed country and sex-specific associations between health status (self-rated health, depression, BMI), healthy behavior (healthy nutrition, physical activity, health awareness), weight satisfaction, and body image concern via a cross-sectional survey (5888 undergraduates) in Egypt, Palestine, and Finland. This health and wellbeing survey employed identical self-administered paper questionnaires administered at several Universities in two Eastern Mediterranean countries (Egypt, Palestine—Gaza Strip), and an online-survey comprising the same questions in Finland. Regression analyses were employed. Health status variables exhibited the strongest associations; high BMI and more depressive symptoms were more often among students satisfied with their weight (except in Palestine), but they were positively associated with body image concern irrespective of country or gender. Self-rated health was not associated with body image concern or weight satisfaction. Healthy behaviors were not associated with body image concern or weight satisfaction. Depressive symptoms and BMI were the most prominent predictors for body image concern. There were country-specific consistent results when using the body image concern score. Further research is necessary to compare body image across different cultures and countries.

Ethical considerations in relation to personalised nutrition : An overview of Work Package 5, with respect to ethics
- 2015
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The objectives of Food4Me work package 5 included a baseline assessment of the ethical and legal aspects of personalised nutrition at the start of the project in 2011, as well as a final assessment at the end of the project (2015), taking into account results achieved in other work packages. The initial assessment made a number of ethical issues visible, most of them relating to the consumer of personalised nutrition service. The results depicted in this publication indicate that many of the questions raised in relation to these issues remain unsolved, and in some cases they seem to be neglected in relation to the services offered by internet companies.

Adolescents' presentation of food in social media: an explorative study
- 2016
-
Ingår i: Appetite. - : Elsevier BV. - 0195-6663 .- 1095-8304. ; 99, s. 121-129
-
Tidskriftsartikel (refereegranskat)abstract
- The study aimed to explore how adolescents communicate food images in a widely used social media image-sharing application. We examined how and in what context food was presented and the type of food items that were frequently portrayed by following a youth related hashtag on Instagram. The hashtag #14år (“14 years”) was used to find adolescent users on Instagram: these users public photo streams were then searched for food items they had shared with others. Food items were identified and categorized based on type of food and how the food items were presented. Most of the adolescent users (85%) shared images containing food items. A majority of the images (67.7%) depicted foods high in calories but low in nutrients. Almost half of these images were arranged as a still life with food brand names clearly exposed. Many of these images were influenced by major food marketing campaigns. Fruits and vegetables occurred in 21.8% of all images. This food group was frequently portrayed zoomed in with focus solely on the food, with a hashtag or caption expressing palatability. These images were often presented in the style of a cook book. Food was thus presented in varied ways. Adolescents themselves produced images copying food advertisements. This has clear health promotion implications since it becomes more challenging to monitor and tackle young people's exposure to marketing of unhealthy foods in these popular online networks because images are part of a lifestyle that the young people want to promote. Shared images contain personal recommendations, which mean that they may have a more powerful effect than commercial advertising.

The Promotion of Eating Behaviour Change through Digital Interventions
- 2020
-
Ingår i: International Journal of Environmental Research and Public Health. - : MDPI. - 1661-7827 .- 1660-4601. ; 17:20

Forskningsöversikt (refereegranskat)abstract
- Diet-related chronic disease is a global health epidemic giving rise to a high incidence of morbidity and mortality. With the rise of the digital revolution, there has been increased interest in using digital technology for eating behavioural change as a mean of diet-related chronic disease prevention. However, evidence on digital dietary behaviour change is relatively scarce. To address this problem, this review considers the digital interventions currently being used in dietary behaviour change studies. A literature search was conducted in databases like PubMed, Cochrane Library, CINAHL, Medline, and PsycInfo. Among 119 articles screened, 15 were selected for the study as they met all the inclusion criteria according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) search strategy. Four primary digital intervention methods were noted: use of personal digital assistants, use of the internet as an educational tool, use of video games and use of mobile phone applications. The efficiency of all the interventions increased when coupled with tailored feedback and counselling. It was established that the scalable and sustainable properties of digital interventions have the potential to bring about adequate changes in the eating behaviour of individuals. Further research should concentrate on the appropriate personalisation of the interventions, according to the requirements of the individuals, and proper integration of behaviour change techniques to motivate long-term adherence.

An umbrella review of systematic reviews on food choice and nutrition published between 2017 and-2019
- 2019
-
Ingår i: Nutrients. - : MDPI. - 2072-6643. ; 11:10
-
Forskningsöversikt (refereegranskat)abstract
- The objective of this umbrella review was to provide an update on the latest knowledge in the field of food choice and nutrition. Databases Scopus and ISI-Web of Science were searched for “food choice” AND nutrition. Papers were included if they were systematic reviews published between January 2017 and August 2019 on any subpopulation group. In total, 26 systematic reviews were kept. Data were extracted with a predetermined grid including first author, publication year, country, population group, explanatory constructs (intervention focus) and reported outcomes. Common indicators for outcome measures on food choice and nutrition studies are nutrition knowledge, healthy food choices, food purchases and food and nutrient intake. The most common strategy implemented to alter food choice with a nutritional aim is nutrition education, followed by provision of information through labels. Among children, parent modelling is key to achieving healthy food choices. In general, combining strategies seems to be the most effective way to achieve healthier food consumption and to maintain good nutrition in all age groups.

Food safety knowledge, sources thereof and self-reported behaviour among university students in Sweden
- 2020
-
Ingår i: Food Control. - : Elsevier. - 0956-7135 .- 1873-7129. ; 113
-
Tidskriftsartikel (refereegranskat)abstract
- International studies have noted shortcomings in food safety knowledge and behaviour among university students. In general students do not constitute a pronounced risk group but there are wider implications. In a foreseeable future some of them will become pregnant and a majority will be responsible for vulnerable groups in their near environment. A crucial question exists, therefore, about their food safety knowledge and safe food handling practices. The aim of this study is to investigate food safety knowledge, sources thereof and self-reported food safety behavior among university students in Sweden. A quantitative study design using a web-based questionnaire was chosen as the data collection method. The questionnaire was distributed through social media and e-mail. Among the 606 respondents from 24 Swedish universities 80% were 18-30 years and 78% were women. The average number of correct answers on the knowledge questions was 7.61 out of 12 (63.4%). The foremost source of food safety knowledge was "Family and friends" (45%). Just 21.1% reported Food safety education as a source, although 35.6% had experience of a course in food hygiene/safety and/or microbiology. Respondents who reported "Family and friends" to be the foremost food safety source of knowledge also got a significantly lower rate of correct answers. Students who estimated their food safety knowledge to be good also had more correct answers. Experience of food safety education at secondary school/university/working place/polytechnic school significantly correlated with more correct answers on the knowledge questions and indicated a safer self-reported behaviour. Those with fewer correct answers also reported more unfavourable behaviours. The present study indicates that education promotes more optimal behaviors. The authors would suggest a more systematic food safety education at younger ages.

Frisk med fisk utan risk? : Betydelsen av svensk konsumtion av sjömat för hälsa och miljö
- 2019
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Seafood is a diverse food commodity, comprising of over 2 500 species from capture fisheries and over 600 species from farming, with vast differences between production methods. Dietary advice often includes recommendations to increase consumption of seafood, based on health benefits and that seafood may be produced with less environmental impacts and resources use compared to many other animal-based foods. However, at the same time, there are frequent media alarms related to potential health risks (some species have diet restrictions) and destructive production practices from both fisheries and aquaculture. As a result, there is often confusion on which seafood to eat or not to eat.The aim of this report is primarily to collate available information on health risks and benefits of Swedish seafood consumption, and to combine this with environmental aspects (focus on carbon footprint).Around 40 seafood products consumed in Sweden were included in the analysis. Potential health risks could only be included qualitatively, since the collected data is risk-based and thus not all products are sampled. It was found that the nutritional content and carbon footprint vastly differ between species. There were also several data gaps identified, such as the need for more detailed data on performance from different production systems. The combined assessment of nutritional value and carbon footprint categorised some species as win-win in terms of nutritional content and environmental pressures (such as small pelagic fish), while others could be more categorised as having less nutritional value and with high environmental costs (such as Northern prawn) respectively.The report provides decision support for further data collection needed to enable combined assessment of nutritional risks, benefits and environmental sustainability of seafood products. Results may be used to discuss suitable level of details of dietary advice.

Empowering aspects for healthy food and physical activity habits : adolescents’ experiences of a school-based intervention in a disadvantaged urban community
- 2018
-
Ingår i: International Journal of Qualitative Studies on Health and Well-being. - Abingdon : Taylor & Francis. - 1748-2623 .- 1748-2631. ; 13:sup1: Equal Health
-
Tidskriftsartikel (refereegranskat)abstract
- Purpose:This study aimed to describe adolescents’ experiences of participating in a health-promoting school-based intervention regarding food and physical activity, with a focus on empowering aspects. Method:The school was located in a urban disadvantaged community in Sweden, characterized by poorer self-reported health and lower life expectancy than the municipality average. Focus group interviews with adolescents (29 girls, 20 boys, 14–15 years) and their teachers (n = 4) were conducted two years after intervention. Data were categorized using qualitative content analysis. Results: A theme was generated, intersecting with all the categories: Gaining control over one’s health: deciding, trying, and practicing together, in new ways, using reflective tools. The adolescents appreciated influencing the components of the intervention and collaborating with peers in active learning activities such as practicing sports and preparing meals. They also reported acquiring new health information, that trying new activities was inspiring, and the use of pedometers and photo-food diaries helped them reflect on their health behaviours. The adolescents’ experiences were also echoed by their teachers. Conclusions: To facilitate empowerment and stimulate learning, health-promotion interventions targeting adolescents could enable active learning activities in groups, by using visualizing tools to facilitate self-reflection, and allowing adolescents to influence intervention activities.

Tidskriftsartikel (refereegranskat)abstract
- Objective: To determine whether an association exists between different clusters of fruit- and vegetable-specific family-environmental factors and children's daily fruit and vegetable intake, and whether these associations differ between countries with different school lunch policies.Design: Cross-sectional data from four European countries participating in the Pro Greens project in 2009. These countries have different school food policies: two serve free school lunches and two do not. Self-administered data were used. Food frequency questions served to assess fruit and vegetable intakes. The study assessed sixteen children-perceived family-environmental factors, which were clustered based on principal component analysis into five sum variables: fruit and vegetable encouragement; vegetable modelling, family routine and demand; fruit modelling; fruit and vegetable snacking practices; and fruit and vegetable allowing.Setting: Schools in Finland, Germany, Sweden and the Netherlands.Subjects: Schoolchildren aged 11 years (n 3317).Results: Multilevel logistic regression analyses revealed positive associations between nearly all clustered family-environmental factors and daily fruit and vegetable intake. The study tested a moderation effect between family-environmental factors and school lunch policy. In five out of twenty models significant interactions occurred. In the stratified analyses, most of the associations between family-environmental factors and raw and cooked vegetable intake were stronger in Germany and the Netherlands, neither of which provided free school lunches.Conclusions: Children reporting more fruit- and vegetable-promoting family-environmental factors had a more frequent intake of fruits and vegetables; the associations were stronger for vegetable intakes in countries providing no free school lunches, suggesting that parental involvement is crucial when schools offer no vegetables

Tidskriftsartikel (refereegranskat)abstract
- Objective: The Nordic countries have published joint dietary recommendations, the Nordic Nutrition Recommendations (NNR), since 1980. We evaluated adherence to the NNR as a measure of a healthy diet and its potential association with self-reported upper respiratory tract infection (URTI). Design: A prospective, population-based study with a follow-up period of 4 months. Dietary intake was assessed using a semi-quantitative FFQ with ninety-six items, along with other lifestyle factors, at baseline. URTI was assessed every three weeks. A Poisson regression model was used to control for age, sex and other confounding factors. Setting: A middle-sized county in northern Sweden. Subjects: Swedish men and women (n 1509) aged 20-60 years. Results: The NNR include recommendations on macronutrient proportions, physical activity and intake of micronutrients, sodium, fibre and alcohol. We found that overall adherence to the NNR was moderately good. In addition, we found that high adherence to the NNR (>5.5 adherence points) was not associated with a lower risk of URTI (incidence rate ratio (IRR) 0.89, 95% CI 0.73, 1.08) compared with low adherence (<4.5 adherence points). When investigating individual components of the NNR, only high physical activity was associated with lower URTI risk (IRR=0.82, 95% CI 0.69, 0.97) whereas none of the dietary components were associated with risk of URTI. Conclusions: Overall adherence to the NNR was moderately good. Overall adherence to the NNR was not associated with URTI risk in our study. However, when investigating individual components of the NNR, we found that high physical activity was associated with lower URTI risk.

Ethical considerations of refusing nutrition after stroke
- 2008
-
Ingår i: Nursing Ethics. - : Sage Publications Ltd.. - 0969-7330 .- 1477-0989. ; 15:2, s. 147-59
-
Tidskriftsartikel (refereegranskat)abstract
- The aim of this article is to analyse and discuss the ethically problematic conflict raised by patients with stroke who refuse nutritional treatment. In analysing this conflict, the focus is on four different aspects: (1) Is nutritional treatment biologically necessary? (2) If necessary, is the reason for refusal a functional disability, lack of appetite or motivation, misunderstanding of the situation or a genuine conflict of values? (3) If the latter, what values are involved in the conflict? (4) How should we deal with the different kinds of refusal of nutritional treatment? We argue that patients' autonomy should be respected as far as possible, while also considering that those who have suffered a stroke might re-evaluate their life as a result of a beneficial prognosis. However, if patients persist with their refusal, health care professionals should force nutritional treatment only when it is clear that the patients will re-evaluate their future life.

- Background: Persistent organic pollutants (POPs) have been suggested to be linked to obesity. We have previously shown that less-chlorinated PCBs were positively related to fat mass, while highly-chlorinated PCBs were inversely related to obesity.Objective: The aim of the present evaluation is to investigate the relationship between retrospective assessed life-time change in body weight (20-70. years) with circulating POP levels measured at age 70. years.Methods: 1016 subjects aged 70. years were investigated in the Prospective Investigation of the Vasculature in Uppsala Seniors (PIVUSs) study. 16 PCBs and 3 OC pesticides were analyzed using HRGC/HRMS. Current body weight was measured and participants self-reported their weight at age 20.Results: The average estimated weight change over 50. years was 14.4. kg. Both the sum of OC pesticide concentrations (4.3. kg more weight gain in quintile 5 vs. quintile 1, p< 0.0001) and the sum of the less-chlorinated PCBs were positively related to the estimated weight change (3.7. kg more weight gain in quintile 2 vs. quintile 1, non-linear relationship p=0.0015). In contrast, the sum of concentrations of highly-chlorinated PCBs were inversely related to estimated weight change (8.4. kg less weight gain in quintile 5 vs. quintile 1, p< 0.0001).Conclusion: High levels of OC pesticides and the less-chlorinated PCBs at age 70 were associated with a pronounced estimated weight change over the previous 50. years. However, the opposite was seen for highly-chlorinated PCBs. Differences in mode of action, toxicokinetics, non-linear relationships and reverse causation might explain these discrepancies.

How barriers towards plant-based food consumption differ according to dietary lifestyle : findings from a consumer survey in 10 EU countries
- 2022
-
Ingår i: International Journal of Gastronomy and Food Science. - : Elsevier. - 1878-450X .- 1878-4518. ; 29
-
Tidskriftsartikel (refereegranskat)abstract
- A diet shift towards a more plant-based food consumption is advocated for sustainable, health and ethical reasons. Still, a diet change remains a societal challenge. The objective of this paper is to identify how barriers towards plant-based food consumption are experienced according to dietary lifestyle in 10 European countries. A pan-EU consumer survey was conducted as part of Smart Protein Project. In total 7590 answers were obtained (49.5% women). Omnivores were more likely to score higher in the barriers to diet shift than vegetarians, vegans or flexitarians. Large effect sizes (Eta squared >0.1) were observed for the following barriers a) the lay belief that humans are meant to eat lots of animal-based meat; b) the expectation that plant-based food products would not be tasty enough; c) and the experience of not enjoying such products. Medium effect sizes (Eta sq. > 0.06) were observed for variables addressing nutrition related barriers “would not be filling enough” and “I would not get energy or strength from these products”. Promotion of plant-based food consumption should be targeted according to diet lifestyle, with focus on their sensory characteristics and on addressing cultural (lay) beliefs e.g. through knowledge sharing.

Re-examination of accelerometer data processing and calibration for the assessment of physical activity intensity.
- 2019
-
Ingår i: Scandinavian Journal of Medicine and Science in Sports. - : John Wiley & Sons. - 0905-7188 .- 1600-0838. ; 29:10, s. 1442-1452

Tidskriftsartikel (refereegranskat)abstract
- This review reexamines use of accelerometer and oxygen uptake data for assessment of activity intensity. Accelerometers capture mechanical work, while oxygen uptake captures the energy cost of this work. Frequency filtering needs to be considered when processing acceleration data. A too restrictive filter attenuates the acceleration signal for walking and, to a higher degree, for running. This measurement error affects shorter (children) more than taller (adults) individuals due to their higher movement frequency. Less restrictive filtering includes more movement related signals and provide measures that better capture mechanical work, but may include more noise. An optimal filter cut-point is determined where most relevant acceleration signals are included. Further, accelerometer placement affects what part of mechanical work being captured. While the waist placement captures total mechanical work and therefore contributes to measures of activity intensity equivalent by age and stature, the thigh and wrist placements capture more internal work and do not provide equivalent measures. Value calibration of accelerometer measures is usually performed using measured oxygen uptake with the metabolic equivalent of task (MET) as reference measure of activity intensity. However, the use of MET is not stringent and is not a measure of activity intensity equivalent by age and stature. A candidate measure is the mass-specific net oxygen uptake, VO2 net (VO2 tot - VO2 stand). To improve measurement of physical activity intensity using accelerometers, research developments are suggested concerning processing of accelerometer data, use of energy expenditure as reference for activity intensity, and calibration procedure with absolute versus relative intensity.

Tidskriftsartikel (refereegranskat)abstract
- The present study aimed at exploring associations among meal-related behaviour, social engagement factors, satisfaction with food-related life (SWFL) to assess food-related wellbeing and subjective wellbeing in Danish older adults living alone. Three hundred and eighty-eight older adults aged 65–75 years from six Danish municipalities completed an online or article-based survey addressing home cooking, commensality, loneliness, SWFL and subjective wellbeing. Home cooking frequency and self-perceived cooking skills were positively associated with SWFL but not with subjective wellbeing. Commensality was positively associated with SWFL but was not associated with subjective wellbeing. The level of loneliness was negatively associated with SWFL and with subjective wellbeing. Satisfaction with food-related life and subjective health status were positively associated with subjective wellbeing. Male and female respondents did not differ in meal-related behaviour, social engagement factors, SWFL and wellbeing. While the cross-sectional nature of this study does not allow for the direction of causality to be determined, these results suggest that older adults living alone could benefit from a higher frequency of home-cooked meals, a higher level of self-perceived cooking skills and commensality to support SWFL. A higher level of SWFL could, in turn, lead to a higher level of wellbeing.

Alkylresorcinol metabolites in urine correlate with the intake of whole grains and cereal fibre in free-living Swedish adults
- 2013

Tidskriftsartikel (refereegranskat)abstract
- Alkylresorcinols (AR) have been established as short/medium-term biomarkers for whole grain (WG) wheat and rye intake; and AR metabolites, 3,5-dihydroxybenzoic acid and 3-(3,5-dihydroxyphenyl)-propanoic acid, have been suggested as complementary biomarkers to AR. The present study examined the medium-term reproducibility and relative validity of urinary AR metabolites as biomarkers for WG and cereal fibre intake. A total of sixty-six free-living Swedes completed 3 d weighed food records and provided single 24 h urine collections and morning urine spot samples on two occasions, 2–3 months apart. The medium-term reproducibility of urinary AR metabolites was moderate when assessed in 24 h collections and lower in creatinine (CR)-adjusted morning urine. Mean AR metabolite 24 h excretions correlated well with total WG (rs 0·31–0·52, P < 0·05) and cereal fibre (rs 0·46–0·58, P < 0·001) intake on both occasions. As expected, correlations with WG (rs 0·28–0·38, P < 0·05) and cereal fibre (rs 0·35–0·42, P < 0·01) were weaker for mean CR-adjusted AR metabolite concentrations in spot samples of morning urine, although the adjusted concentrations correlated well with 24 h urinary excretion (rs 0·69–0·73, P < 0·001). Adjustment for intra-individual variations substantially improved the correlations between intake and excretion. These findings suggest that urinary AR metabolites can successfully reflect the medium-term intake of WG and cereal fibre when adjusted for intra-individual variation in this population, where rye was the major contributor to high WG intake. The performance of urinary AR metabolites as medium-term biomarkers appears to be comparable to that of fasting plasma AR concentration in this population.

'Don't give us an assignment where we have to use spinach!' : food choice and discourse in home and consumer studies

Tidskriftsartikel (refereegranskat)abstract
- The aim of the study was to describe classroom Discourses about vegetables during the planning, cooking, eating and evaluation of meals in the Swedish school subject Home and Consumer Studies. Fifty-nine students and five teachers were recruited from five northern Swedish villages and towns, and then observed, recorded and in some cases video-taped during lessons that took place between 2010 and 2012. Based on 56 instances of talk about vegetables, four Discourses were identified and related to the three aspects of Belasco's culinary triangle of contradictions: identity, responsibility and convenience. The results indicated that the identity-based sensory and cultural Discourses sometimes clashed with the more responsibility-oriented health and evaluation Discourses. The health Discourse was only used when there was an element of evaluation, with assignments connected to grades. In all other cases, the sensory and cultural Discourses guided vegetable use. Sometimes different sensory or cultural assumptions could clash with each other, for example when the teacher insisted on the use of a specific recipe regardless of a student's taste preferences. Since these preferences did not always harmonize with curricular demands for responsibility, there might be a risk of basing grades on aspects of students' identity. Alternatively, students might feel constrained to argue against their own identity in order to be favourably evaluated. Then again, if teachers always bow to student tastes, this limits their chances of learning about food and physical health. Viewing the dilemma through the lens of the culinary triangle of contradictions may help teachers and researchers develop teaching methods that take all aspects of food choice into account.

Tidskriftsartikel (refereegranskat)abstract
- This study investigates elite coaches’ attitudes toward eating disorders (ED), knowledge about ED, and early intervention skills when confronted with possible ED in their female athletes. We interviewed 18 coaches in Sweden responsible for athletes representing national teams in the three sports categories most at risk for ED: aesthetic, weight class, and endurance. The interviews revealed that, although most coaches knew athletes with ED, they did not perceive ED as a problem in their sport. The majority of coaches cited difficulties in identifying ED symptoms, especially symptoms associated with bulimia nervosa. Coaches also described several barriers in approaching the athletes, including the athletes’ denial of ED, lack of female colleagues on the team and the lack of easily accessible resources for treatment referral on both the national sports federation and the club levels. This study reveals that elite coaches have insufficient capacity to identify ED and conduct early intervention, resulting in delayed treatment.

Tidskriftsartikel (refereegranskat)abstract
- Orthorexia nervosa is described as an exaggerated fixation on healthy food. It is unclear whether students in health-oriented academic programs, highly focused on physical exercise, are more prone to develop orthorexia nervosa than students in other educational areas. The aim was to compare health status, physical activity, and frequency of orthorexia nervosa between university students enrolled in an exercise science program (n = 118) or a business program (n = 89). The students completed the Short Form-36 Health Survey (SF-36), the International Physical Activity Questionnaire (IPAQ), and ORTO-15, which defines orthorexia nervosa as a sensitive and obsessive behavior towards healthy nutrition. The SF-36 showed that exercise science students scored worse than business students regarding bodily pain (72.8 vs. 82.5; p = 0.001), but better regarding general health (83.1 vs. 77.1; p = 0.006). Of 188 students, 144 (76.6%) had an ORTO-15 score indicating orthorexia nervosa, with a higher proportion in exercise science students than in business students (84.5% vs. 65.4%; p = 0.002). Orthorexia nervosa in combination with a high level of physical activity was most often seen in men in exercise science studies and less often in women in business studies (45.1% vs. 8.3%; p < 0.000). A high degree of self-reporting of pain and orthorexia nervosa in exercise science students may cause problems in the future, since they are expected to coach others in healthy living. Our findings may be valuable in the development of health-oriented academic programs and within student healthcare services. © 2016 Elsevier Ltd

- SCOPE: Whole grain (WG) intake is associated with decreased risk of developing colorectal cancer, type 2 diabetes and cardiovascular disease and its comorbidities. However, the role of specific grains is unclear. Moreover, intake of specific WG is challenging to measure accurately with traditional dietary assessment methods. Our aim was to use non-targeted metabolite profiling to discover specific urinary biomarkers for WG rye to objectively reflect intake under free-living conditions.METHODS AND RESULTS: WG rye intake was estimated by weighed food records, and 24 h urine collections were analyzed by LC-MS. Multivariate modelling was undertaken by repeated double cross-validated partial least squares regression against reported WG rye intake, which correlated well with multivariate prediction estimates (r = 0.67-0.80, p<0.001), but not with intakes of WG wheat or oats. Hydroxyhydroxyphenyl acetamide (HHPA) sulfate, 3,5-dihydroxyphenylpropionic acid (DHPPA) sulfate, caffeic acid sulfate and hydroxyphenyl acetamide (HPAA) sulfate were among the 20 features which had the greatest potential as intake biomarkers of WG. In addition, three compounds exhibited MS/MS fragmentation of carnitine structures.CONCLUSION: With this non-targeted approach, we confirmed the specificity of alkylresorcinol metabolites as biomarkers for WG rye intake, but also discovered other compounds that should be evaluated as putative biomarkers in future studies.

Use of a Web-Based Dietary Assessment Tool (RiksmatenFlex) in Swedish Adolescents: Comparison and Validation Study
- 2019
-
Ingår i: Journal of Medical Internet Research. - : JMIR Publications Inc.. - 1438-8871. ; 21:10
-
Tidskriftsartikel (refereegranskat)abstract
- Background: A Web-based dietary assessment tool-RiksmatenFlex-was developed for the national dietary survey of adolescents in Sweden. Objective: This study aimed to describe the Web based method RiksmatenFlex and to test the validity of the reported dietary intake by comparing dietary intake with 24-hour dietary recalls (recall interviews), estimated energy expenditure, and biomarkers. Methods: Adolescents aged 11-12, 14-15, and 17-18 years were recruited through schools. In total, 78 students had complete dietary information and were included in the study. Diet was reported a few weeks apart with either RiksmatenFlexDiet (the day before and a random later day) or recall interviews (face-to-face, a random day later by phone) in a cross-over, randomized design. At a school visit, weight and height were measured and blood samples were drawn for biomarker analyses. Students wore an accelerometer for 7 days for physical activity measurements. Dietary intake captured by both dietary methods was compared, and energy intake captured by both methods was compared with the accelerometer-estimated energy expenditure (EEest). Intake of whole grain wheat and rye and fruit and vegetables by both methods was compared with alkylresorcinol and carotenoid concentrations in plasma, respectively. Results: The mean of the reported energy intake was 8.92 (SD 2.77) MJ by RiksmatenFlexDiet and 8.04 (SD 2.67) MJ by the recall interviews (P=.01) Intake of fruit and vegetables was 224 (169) g and 227 (150) g, and whole grain wheat and rye intake was 12.4 (SD 13.2) g and 12.0 (SD 13.1) g, respectively; the intakes of fruit and vegetables as well as whole grain wheat and iye did not differ between methods. Intraclass correlation coefficients ranged from 0.57 for protein and carbohydrates to 0.23 for vegetables. Energy intake by RiksmatenFlexDiet was overreported by 8% (P=.03) but not by the recall interviews (P=.53) compared with EEest. The Spearman correlation coefficient between reported energy intake and EEest was 0.34 (P=.008) for RiksmatenFlexDiet and 0.16 (P=.21) for the recall interviews. Spearman correlation coefficient between whole grain wheat and rye and plasma total alkylresorcinol homologs was 0.36 (P=.002) for RiksmatenFlexDiet and 0.29 (P=.02) for the recall interviews. Spearman correlations between intake of fruit and vegetables and plasma carotenoids were weak for both dietary tools. The strongest correlations were observed between fruit and vegetable intake and lutein/zeaxanthin for RiksmatenFlexDiet (0.46; P<.001) and for recall interviews (0.28; P=.02). Conclusions: RiksmatenFlexDiet provides information on energy, fruit, vegetables, and whole grain wheat and rye intake, which is comparable with intake obtained from recall interviews in Swedish adolescents. The results are promising for cost-effective dietary data collection in upcoming national dietary surveys and other studies in Sweden. Future research should focus on how, and if, new technological solutions could reduce dietary reporting biases.

- Cereal grains are the main dietary source of energy, carbohydrates, and plant proteins world-wide. Currently, only 41% of grains are used for human consumption, and up to 35% are used for animal feed. Cereals have been overlooked as a source of environmentally sustainable and healthy plant proteins and could play a major role in transitioning towards a more sustainable food system for healthy diets. Cereal plant proteins are of good nutritional quality, but lysine is often the limiting amino acid. When consumed as whole grains, cereals provide health-protecting components such as dietary fiber and phytochemicals. Shifting grain use from feed to traditional foods and conceptually new foods and ingredients could improve protein security and alleviate climate change. Rapid development of new grain-based food ingredients and use of grains in new food contexts, such as dairy replacements and meat analogues, could accelerate the transition. This review discusses recent developments and outlines future perspectives for cereal grain use.

Parental Prepuberty Overweight and Offspring Lung Function
- 2022

Ingår i: Nutrients. - : MDPI AG. - 2072-6643. ; 14:7
-
Tidskriftsartikel (refereegranskat)abstract
- In a recent study we found that fathers' but not mothers' onset of overweight in puberty was associated with asthma in adult offspring. The potential impact on offspring's adult lung function, a key marker of general and respiratory health, has not been studied. We investigated the potential causal effects of parents' overweight on adult offspring's lung function within the paternal and maternal lines. We included 929 offspring (aged 18-54, 54% daughters) of 308 fathers and 388 mothers (aged 40-66). Counterfactual-based multi-group mediation analyses by offspring's sex (potential moderator) were used, with offspring's prepubertal overweight and/or adult height as potential mediators. Unknown confounding was addressed by simulation analyses. Fathers' overweight before puberty had a negative indirect effect, mediated through sons' height, on sons' forced expiratory volume in one second (FEV1) (beta (95% CI): -144 (-272, -23) mL) and forced vital capacity (FVC) (beta (95% CI): -210 (-380, -34) mL), and a negative direct effect on sons' FVC (beta (95% CI): -262 (-501, -9) mL); statistically significant effects on FEV1/FVC were not observed. Mothers' overweight before puberty had neither direct nor indirect effects on offspring's lung function. Fathers' overweight starting before puberty appears to cause lower FEV1 and FVC in their future sons. The effects were partly mediated through sons' adult height but not through sons' prepubertal overweight.

Dietary reforms in the Baltic and East Central Europe, ca 1850–1950
- 2022
-
Samlingsverk (redaktörskap) (refereegranskat)abstract
- In this special section, the histories of dietary reform have been approached and explored from different perspectives. The essays weave together threads of the history of dietary advice and nutritional standards with social history, women’s history and food history, covering the elements of life reform and women’s movements, the establishment of communist food ideology, the development of modern food safety and food security, etc. Three peer-reviewed articles focusing on the case studies of Estonia, Bulgaria and the Russian empire are built on previously untapped sources and offer original perspectives on the topic. As the contributions suggest, the entangled histories of dietary reform efforts proved to be a valuable and novel prism through which to study the region and the history of Europe in general.

Designing Nutritionally Adequate and Climate-Friendly Diets for Omnivorous, Pescatarian, Vegetarian and Vegan Adolescents in Sweden Using Linear Optimization
- 2021
-
Ingår i: Nutrients. - : MDPI AG. - 2072-6643. ; 13:8
-
Tidskriftsartikel (refereegranskat)abstract
- Low-carbon diets can counteract climate change and promote health if they are nutritionally adequate, affordable and culturally acceptable. This study aimed at developing sustainable diets and to compare these with the EAT-Lancet diet. The Swedish national dietary survey Riksmaten Adolescents 2016-2017 was used as the baseline. Diets were optimized using linear programming for four dietary patterns: omnivores, pescatarians, vegetarians and vegans. The deviation from the baseline Riksmaten diet was minimized for all optimized diets while fulfilling nutrient and climate footprint constraints. Constraining the diet-related carbon dioxide equivalents of omnivores to 1.57 kg/day resulted in a diet associated with a reduction of meat, dairy products, and processed foods and an increase in potatoes, pulses, eggs and seafood. Climate-friendly, nutritionally adequate diets for pescatarians, vegetarians and vegans contained fewer foods and included considerable amounts of fortified dairy and meat substitutes. The optimized diets did not align very well with the food-group pattern of the EAT-Lancet diet. These findings suggest how to design future diets that are climate-friendly, nutritionally adequate, affordable, and culturally acceptable for Swedish adolescents with different dietary patterns. The discrepancies with the EAT diet indicate that the cultural dietary context is likely to play an important role in characterizing sustainable diets for specific populations.

Perspective: Metabotyping—A Potential Personalized Nutrition Strategy for Precision Prevention of Cardiometabolic Disease
- 2020

Forskningsöversikt (refereegranskat)abstract
- Diet is an important, modifiable lifestyle factor of cardiometabolic disease risk, and an improved diet can delay or even prevent the onset of disease. Recent evidence suggests that individuals could benefit from diets adapted to their genotype and phenotype: that is, personalized nutrition. A novel strategy is to tailor diets for groups of individuals according to their metabolic phenotypes (metabotypes). Randomized controlled trials evaluating metabotype-specific responses and nonresponses are urgently needed to bridge the current gap of knowledge with regard to the efficacy of personalized strategies in nutrition. In this Perspective, we discuss the concept of metabotyping, review the current literature on metabotyping in the context of cardiometabolic disease prevention, and suggest potential strategies for metabotype-based nutritional advice for future work. We also discuss potential determinants of metabotypes, including gut microbiota, and highlight the use of metabolomics to define effective markers for cardiometabolic disease-related metabotypes. Moreover, we hypothesize that people at high risk for cardiometabolic diseases have distinct metabotypes and that individuals grouped into specific metabotypes may respond differently to the same diet, which is being tested in a project of the Joint Programming Initiative: A Healthy Diet for a Healthy Life.

Food desires and hedonic discrimination in virtual reality varying in product–context appropriateness among older consumers
- 2022
-
Ingår i: Foods. - : MDPI. - 2304-8158. ; 11:20
-
Tidskriftsartikel (refereegranskat)abstract
- Immersive virtual reality (VR) videos can replicate complex real-life situations in a systematic, repeatable and versatile manner. New product development trajectories should consider the complexities of daily life eating situations. The creation of immersive contexts of a product with varying levels of appropriateness could be a useful tool for product developers in evaluating the extent to which context may influence food acceptance and eating behavior. This study explored virtual reality (VR) as an efficient context-enhancing technology through evaluations of protein-enriched rye breads and compared the effects of a VR-simulated congruent (VR restaurant) and incongruent (VR cinema) contexts on the acceptance in older consumers. A total of 70 participants were immersed in the two VR contexts and a neutral control context in a randomized order. The responses indicating the desire and liking for rye breads were measured, and the extent of immersion during context exposure was assessed by levels of the sense of presence and engagement. Immersive VR induced positive sensations of presence and a heightened level of engagement. The VR restaurant and neutral contexts were perceived as more appropriate for consuming rye breads and induced higher desire and liking for rye breads, which supported the notion of the alignment of congruent contexts with food desire and liking. The study provides new perspectives, practical methodologies, and discoveries in regard to the creation and application of VR-immersed contexts in food product evaluation. Moreover, it focused on a consumer segment (older consumers) that has seldom been investigated in previous relevant studies. The findings suggest that immersive VR technology, as a tool for evaluating contextual factors, is important for new product development. The good user experience among older consumers further indicated the potential value of VR as a context-enhancing tool for product development.

Tidskriftsartikel (refereegranskat)abstract
- Respiration rate is an important healthcare indicator, and it has become a popular research topic in remote healthcare applications with Internet of Things. Existing respiration monitoring systems have limitations in terms of convenience, comfort, and privacy, etc. This paper presents a contactless and real-time respiration monitoring system, the so-called Wi-Breath, based on off-the-shelf WiFi devices. The system monitors respiration with both the amplitude and phase difference of the WiFi channel state information (CSI), which is sensitive to human body micro movement. The phase information of the CSI signal is considered and both the amplitude and phase difference are used. For better respiration detection accuracy, a signal selection method is proposed to select an appropriate signal from the amplitude and phase difference based on a support vector machine (SVM) algorithm. Experimental results demonstrate that the Wi-Breath achieves an accuracy of 91.2% for respiration detection, and has a 17.0% reduction in average error in comparison with state-of-the-art counterparts.

- The aim of the present study is to explore experienced home economics (HE) teachers’ perceptions of the influencing factors that condition their teaching opportunities regarding the revised mission to implement sustainable development (SD) in food-related education. Five purposefully selected HE teachers participated in individual, semi-structured, in-depth interviews. The recorded interviews were transcribed verbatim and analysed using qualitative thematic analysis. The results show a shared view of in the importance of educating the next generation of sustainable food consumers. Teachers returned to specific influencing factors that conditioned their opportunities to implement a perspective of SD in HE food education. This generated four themes: (1) Unscheduled foodwork in preparing sustainable food education, (2) opportunities to link everyday food choices with larger food system issues, (3) access to sustainable supportive food products and materials, and (4) a school environment in support of food-related teaching. The teachers outlined a number of local and national factors perceived to inhibit access to facilitators and expressed a concern for pupils’ opportunities for quality assurance and goal achievement. The suggested influencing factors could serve as propositions for further investigations in the continued work of both resource reinforcements as well as of developing a SD perspective in food-related HE education. © 2018 by the author.

Ordinary mealtimes under extraordinary circumstances : Routines and rituals of nutrition, feeding and eating in children with a gastrostomy and their families
- 2021
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The aim of this thesis is to explore routines and rituals related to feeding, eating, and mealtimes in families that have a child with a gastrostomy tube (G-tube), from the perspectives of healthcare professionals, the children, and their parents. The thesis is based on four empirical studies. Study I is a longitudinal, quantitative study with the aim to describe children with developmental or acquired disorders receiving a G-tube, and to compare characteristics, contacts with healthcare professionals, and longitudinal eating outcomes. Findings from Study I demonstrated that children with developmental disorders needed G-tube feeding for longer than children with acquired disorders. Children with developmental disorders were also younger at G-tube placement, and had more multidisciplinary healthcare. These findings led to the subsequent studies focused specifically on children with developmental disorders. Study II applies mixed methods and explores everyday life, health care, and intervention goals during the first year following G-tube placement through the documentation in medical records. In Studies III and IV, the experiences of family mealtimes for children with a G-tube and their parents are collected through individual interviews that are analysed qualitatively. Triangulation of methods, participants, researchers, and data across the four studies is applied to search for confirmation between findings, as well as to identify areas of discrepancy. Ecocultural theory, the WHO framework ICF, and the concept of participation form the conceptual framework of the thesis. Taken together, findings from the studies describe how the main experiences of feeding, eating, and mealtime relate to specific impairments of the child, the collective value attached to family mealtimes, and the parental responsibility to harmonise competing interests and conflicts among family members and/or healthcare professionals. This thesis extends previous research by focusing on the ecocultural context of the child in combination with a dimensional understanding of health. The findings shed light on measures taken by the families themselves to adjust to and handle their daily lives, as well as spell out areas where more support is needed. Furthermore, this thesis suggests that an expanded focus on children’s participation in everyday mealtimes, and in the healthcare follow-up of G-tube feeding, is important in enhancing intervention outcomes.

Dietary Fatty Acids and Inflammation : Observational and Interventional Studies
- 2011
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Dietary fat quality influences the risk of type 2 diabetes and cardiovascular disease. A low-grade inflammation is suggested to contribute to the disease development, often accompanied by obesity. Whereas n-3 polyunsaturated fatty acids (PUFA) have been considered anti-inflammatory, n-6 PUFA have been proposed to act pro-inflammatory. Saturated fatty acids (SFA) act pro-inflammatory in vitro. This thesis aimed to investigate effects of different fatty acids on low-grade inflammation in observational and interventional studies. In Paper I and II, fatty acid composition in serum cholesterol esters was used as objective marker of dietary fat quality and related to serum C-reactive protein (CRP) and other circulating inflammatory markers in two population-based cohorts, conducted in middle-aged men and elderly men and women, respectively. In Paper III and IV, the impact of diets differing in fat quality on inflammation and oxidative stress was investigated in randomised controlled studies, in subjects with metabolic syndrome and abdominal obesity. In Paper I and II, a low proportion of linoleic acid (18:2 n-6) in serum was associated with higher CRP concentrations, indicating that a low intake of vegetable fats may be related to low-grade inflammation. High CRP concentrations were also associated with high proportions of palmitoleic (16:1) and oleic (18:1) acids and high stearoyl coenzymeA desaturase index, possibly reflecting altered fat metabolism and/or high SFA intake in this population. When comparing two high-fat diets rich in either saturated or monounsaturated fat, and two low-fat diets with or without long-chain n-3 PUFA supplementation during 12 weeks (Paper III), no differences in inflammation or oxidative stress markers were observed. Moreover, a 10-week intervention (Paper IV) with high linoleic acid intake showed no adverse effects on inflammation or oxidative stress. Instead, interleukin-1 receptor antagonist and tumor necrosis factor receptor-2 decreased after linoleic acid intake compared with a diet high in SFA. The results in this thesis indicate that dietary n-6 PUFA found in vegetable fats is associated with lower inflammation marker levels, and to some extent reduces systemic inflammation when compared with SFA. Supplementation of n-3 PUFA did not exert any systemic anti-inflammatory effects, maybe due to a relatively low dose.

- Background: Metabolomics represents a powerful tool for exploring modulation of the human metabolome in response to food intake. However, the choice of multivariate statistical approach is not always evident, especially for complex experimental designs with repeated measurements per individual. Here we have investigated the serum metabolic responses to two breakfast meals: an egg and ham based breakfast and a cereal based breakfast using three different multivariate approaches based on the Projections to Latent Structures framework. Methods: In a cross over design, 24 healthy volunteers ate the egg and ham breakfast and cereal breakfast on four occasions each. Postprandial serum samples were subjected to metabolite profiling using H-1 nuclear magnetic resonance spectroscopy and metabolites were identified using 2D nuclear magnetic resonance spectroscopy. Metabolic profiles were analyzed using Orthogonal Projections to Latent Structures with Discriminant Analysis and Effect Projections and ANOVA-decomposed Projections to Latent Structures. Results: The Orthogonal Projections to Latent Structures with Discriminant Analysis model correctly classified 92 and 90% of the samples from the cereal breakfast and egg and ham breakfast, respectively, but confounded dietary effects with inter-personal variability. Orthogonal Projections to Latent Structures with Effect Projections removed inter-personal variability and performed perfect classification between breakfasts, however at the expense of comparing means of respective breakfasts instead of all samples. ANOVA-decomposed Projections to Latent Structures managed to remove inter-personal variability and predicted 99% of all individual samples correctly. Proline, tyrosine, and N-acetylated amino acids were found in higher concentration after consumption of the cereal breakfast while creatine, methanol, and isoleucine were found in higher concentration after the egg and ham breakfast. Conclusions: Our results demonstrate that the choice of statistical method will influence the results and adequate methods need to be employed to manage sample dependency and repeated measurements in cross-over studies. In addition, H-1 nuclear magnetic resonance serum metabolomics could reproducibly characterize postprandial metabolic profiles and identify discriminatory metabolites largely reflecting dietary composition.

- A category of symptoms that became characteristic early in the first wave of the coronavirus disease 2019 (COVID-19) pandemic was chemosensory dysfunctions (alterations ofsmell and taste). Such symptoms substantially affect food and eating – cornerstones for both nutrition-related health outcomes and for quality of life. Based on this, this scoping review aimed to map out existing scientific literature on food-related experiences and related behavioral responses among people affected by chemosensory dysfunctions following COVID-19. A librarian-supported search of PsycInfo, PubMed, and Scopus for publications written in English (2020 to April 26, 2022) was conducted. Two authors searched for and screened publications and three others extracted and collated data. These are reported following the Preferred Reporting Items of Systematic reviews and Meta-Analyses extension for Scoping Reviews. Of 1169 hits, 9 publications were included in the review. The results are thematized as “Psychological and social aspects” and “Nutritional aspects,” each with the subsections “Experiences” and “Behavioral responses.” A great variety of food-related problems, nutritional and mental health effects, and implications for social life are identified. People affected by chemosensory dysfunctions following COVID-19 suffer, as evident both in stories from qualitative studies and in measurements of quality of life. The results impact all professions who are and may come to be involved in treating these patients, such as nurses, physicians, dietitians, and psychologists. With more knowledge about the dysfunctions’ manifestation, duration, and impact on everyday life, multiprofessional teams need to collaborate in supporting patients medically, psychosocially, and nutritionally.

Education for sustainable food consumption in home and consumer studies : Lärande för hållbar matkonsumtion i hem- och konsumentkunskap
- 2018
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Education as a means to enable sustainable food consumption has gained increasing recognition as a vital means to decrease current burdens upon both natural resources and human health. In response, the Swedish compulsory school subject of home and consumer studies, which positions education about food as core content, has been revised to incorporate in its national syllabus a perspective of sustainable development since 2011. However, because sustainable development remains an ambiguous, contested concept with a range of definitions and interpretations, it is necessary to gain better understanding of what incorporating its perspective can entail in home and consumer studies, particularly regarding the core food-related content knowledge that it teaches. Building upon four papers, this thesis reports research guided by an interpretive and exploratory approach that involved analysing data from syllabuses, observations, recordings of in-class lessons and interviews with practising teachers. The results reveal two ways of understanding what incorporating a perspective of sustainable development can entail in home and consumer studies in Sweden. The first understanding proposes an enriched and unified practice in which the curriculum prioritises embodied forms of knowledge about healthy, ethical and resource-efficient food consumption by allowing a multi-relational, systems thinking approach while focusing a homemade meal practice. By contrast, the second understanding proposes a practice riddled with inconsistencies and contradictions in providing teaching and learning opportunities to attain the intended goals. This ultimately results in fragmented learning opportunities focused more on informed reasoning than on informed actions. Taken together, both understandings pose theoretical, conceptual and practical implications, both for home and consumer studies in particular and in education for sustainable food consumption in general.

Tidskriftsartikel (refereegranskat)abstract
- Background: The excretion of amino acids in urine represents an important avenue for the loss of key nutrients. Some amino acids such as glycine and histidine are lost in higher abundance than others. These two amino acids perform important physiological functions and are required for the synthesis of key proteins such as haemoglobin and collagen. Methods: Stage 1 of this study involved healthy subjects(n = 151) who provided first of the morning urine samples and completed symptom questionnaires. Urine was analysed for amino acid composition by gas chromatography. Stage 2 involved a subset of the initial cohort (n = 37) who completed a 30 day trial of an amino acid supplement and subsequent symptom profile evaluation. Results: Analyses of urinary amino acid profiles revealed that three groups could be objectively defined from the 151 participants using k-means clustering. The amino acid profiles were significantly different between each of the clusters (Wilks' Lambda = 0.13, p < 0.0001). Cluster 1 had the highest loss of amino acids with histidine being the most abundant component. Cluster 2 had glycine present as the most abundant urinary amino acid and cluster 3 had equivalent abundances of glycine and histidine. Strong associations were observed between urinary proline concentrations and fatigue/pain scores (r =.56 to.83) for females in cluster 1, with several other differential sets of associations observed for the other clusters. Conclusions: Different phenotypic subsets exist in the population based on amino acid excretion characteristics found in urine. Provision of the supplement resulted in significant improvements in reported fatigue and sleep for 81% of the trial cohort with all females reporting improvements in fatigue.

- Objectives The present study evaluates body circumferences as a nutrition screening tool for women of reproductive age with children less than 5 years of age to improve the detection of overweight and obesity in a community setting.Design This study draws data from a community-based cross-sectional study conducted between July–August 2017 and January–February 2018 to account for seasonality in Addis Ababa, Ethiopia.Setting One hundred and sixteen districts were included in Addis Ababa, Ethiopia.Participants A total of 4914 women of reproductive age with children less than 5 years of age were participated in this study.Primary and secondary outcome measures Primary outcome measures included anthropometric indices. There were no secondary outcomes.Results The optimal cut-off points to identify overweight women of reproductive age were >87.5 cm for waist circumference (WC), >31.7 cm for neck circumference (NC) and >28.0 cm for mid-upper arm circumference (MUAC) based on the highest corresponding Youden index. The area under the receiver operating characteristics curve was 0.92 (95% CI: 0.91 to 0.93) for WC, 0.83 (95% CI: 0.82 to 0.84) for NC and 0.91 (95% CI: 0.89 to 0.92) for MUAC.Conclusions Our result shows that WC and MUAC are alternative tools to body mass index. Both WC and MUAC are effective in identifying overweight women. We recommend using MUAC in large-scale population-based assessments to identify overweight and obesity in low-income settings as it is logistically simpler and operationally feasible.

- Scope: Fermentation improves many food characteristics using microbes, such as lactic acid bacteria (LAB). Recent studies suggest fermentation may also enhance the health properties, but mechanistic evidence is lacking. We aimed to identify a metabolite pattern reproducibly produced during sourdough and in vitro colonic fermentation of various whole-grain rye products and how it affects the growth of bacterial species of potential importance to health and disease.Methods and results: We used Lactiplantibacillus plantarum DSMZ 13890 strain, previously shown to favour rye as its substrate. Using LC-MS metabolomics, we found seven microbial metabolites commonly produced during the fermentations, including dihydroferulic acid, dihydrocaffeic acid, and five amino acid metabolites, and stronger inhibition was achieved when exposing the bacteria to a mixture of the metabolites in vitro compared to individual compound exposures.Conclusion: Our study suggests that metabolites produced by LAB may synergistically modulate the local microbial ecology, such as in the gut. This could provide new hypotheses on how fermented foods influence human health via diet–microbiota interactions.

Body mass index and gestational weight gain in migrant women by birth regions compared with Swedish-born women : A registry linkage study of 0.5 million pregnancies
- 2020
-
Ingår i: PLOS ONE. - : Public Library of Science (PLoS). - 1932-6203. ; 15:10

Tidskriftsartikel (refereegranskat)abstract
- INTRODUCTION: Women migrating to high-income countries may have increased risks of adverse pregnancy outcomes as compared with native-born women. However, little is known whether migrant women are more likely to have unhealthy body mass index (BMI) or gestational weight gain (GWG), which is of importance considering the well-established links between unhealthy BMI and GWG with adverse pregnancy outcomes. Hence, the aim of the study was to examine the prevalence and estimate odds ratios (ORs) of underweight and obesity in the first trimester as well as inadequate and excessive GWG across birth regions in migrant (first-generation) and Swedish-born women in a population-based sample of pregnant women in Sweden.METHODS: This population-based study included 535 609 pregnancies from the Swedish Pregnancy Register between the years 2010-2018. This register has a coverage of approximately 90% and includes data on body weight, height, birth country and educational attainment. BMI in the first trimester of pregnancy was classified as underweight, normal weight, overweight and obesity whereas GWG was classified as inadequate, adequate and excessive according to the recommendations from the National Academy of Medicine, USA. BMI and GWG were examined according to 7 birth regions and the 100 individual birth countries. Adjusted ORs of underweight, obesity as well as inadequate or excessive GWG by birth regions were estimated using multinomial logistic regression.RESULTS: There were large disparities in unhealthy BMI and GWG across birth regions. For instance, women born in North Africa and Middle East and Sub-Saharan Africa had 1.40 (95% CI 1.35-1.44) and 2.13 (95% CI 2.03-2.23) higher odds of obesity compared with women born in Sweden. However, women born in Sub-Saharan Africa had also considerably higher odds of underweight (OR, 2.93 [95% CI 2.70-3.18]) and inadequate GWG (OR, 1.97 [95% CI 1.87-2.07]). The limitations of the study include the lack of a validated measure of acculturation and that the study only had data on first-generation migration.CONCLUSIONS: The large differences across the 7 regions and 100 countries highlights the importance of considering birth region and country-specific risks of unhealthy BMI and GWG in first-generation migrant women. Furthermore, inadequate GWG was common among pregnant first-generation migrant women, especially in women born in Sub-Saharan Africa, which demonstrates the need to promote adequate GWG, not only the avoidance of excessive GWG. Thus, our findings also indicate that additional support and interventions may be needed for first-generation migrant women from certain birth regions and countries in order to tackle the observed disparities in unhealthy BMI and GWG. Although further studies are needed, our results are useful for identifying groups of women at increased risk of unhealthy BMI and weight gain during pregnancy.

- Antigen-specific chicken IgY antibodies have been used for oral immunotherapy as an alternative or complement to antibiotics in several studies. The water dilution (WD) method has several advantages for purifying IgY. It is rapid, efficient, suitable for large-scale production, and nothing but water is added. The water-soluble fraction contains other proteins and lipids besides IgY. The protein content was characterized by two-dimensional gel electrophoresis (2DGE) and nanoflow liquid chromatography coupled offline to matrix-assisted laser desorption/ionization time-of-flight tandem mass spectrometry (nanoLC-MALDI TOF/TOF MS). Protein analysis was complicated due to the large dynamic concentration range, but 26 proteins could be identified. The relative protein concentrations in different batches were very similar according to protein patterns on 1D gels and protein concentration determinations. Thus, the purification method has a high reproducibility. The concentrations of cholesterols and triglycerides were low and should not have an effect on the plasma levels of treated patients. Purification of IgY for oral use with WD is therefore a recommended method.

- Objective: To evaluate time trends in the availability of soft drinks, to identify food choices associated with their consumption and to assess the relationship between socio-economic status and daily soft drink availability in a wide range of European countries.Design: Data on food and beverage availability collected through the national household budget surveys and harmonized in the DAFNE (Data Food Networking) project were used. Averages and variability of soft drink availability were estimated and tests for time trends were performed. The daily availability of food groups which appear to be correlated with that of soft drinks was further estimated. Multivariate logistic and linear regression models were applied to evaluate the association between socio-economic status and the acquisition of soft drinks.Setting: Twenty-four European countries.Subjects: Nationally representative samples of households.Results: The availability of soft drinks is steadily and significantly increasing. Households in West and North Europe reported higher daily availability of soft drinks in comparison to other European regions. Soft drinks were also found to be correlated with lower availability of plant foods and milk and higher availability of meat and sugar products. Lower socio-economic status was associated with more frequent and higher availability of soft drinks in the household.Conclusions: Data collected in national samples of twenty-four European countries showed disparities in soft drink availability among socio-economic strata and European regions. The correlation of soft drinks with unfavourable dietary choices has public health implications, particularly among children and adolescents.

- Our objective was to investigate the long-term metabolic effects of postnatal essential fatty acid deficiency (EFAD). Mouse dams were fed an EFAD diet or an isoenergetic control diet 4 days before delivery and throughout lactation. The pups were weaned to standard diet (STD) and were later subdivided into two groups: receiving high fat diet (HFD) or STD. Body composition, energy expenditure, food intake and leptin levels were analyzed in adult offspring. Blood glucose and plasma insulin concentrations were measured before and during a glucose tolerance test. EFAD offspring fed STD were leaner with lower plasma leptin and insulin concentrations compared to controls. EFAD offspring fed HFD were resistant to diet-induced obesity, had higher energy expenditure and lower levels of plasma leptin and insulin compared to controls. These results indicate that the fatty acid composition during lactation is important for body composition and glucose tolerance in the adult offspring.
