- Intramuscular ceruletide or placebo was given in a randomized double-blind crossover design to 12 non-obese and 12 obese individuals, 30 min before a palatable lunch meal. No significant effects were found on the amount of food intake or the hunger ratings in any group. Although rapid CCK or ceruletide infusions have been found in some studies to reduce food intake in man and animals, slow infusions have increased food intake. Under the present study conditions, the moderate rate of release of ceruletide from intramuscular depots did not affect the food intake.

- In a town in northern Sweden, 3.3% of the 15-year-old adolescents were vegans in 1996. This study describes the process of becoming a vegan among adolescents and interprets the informants' descriptions by constructing categories, which later on were related to relevant theories. Group interviews were conducted with three vegans and in-depth interviews were performed with three other vegan adolescents. The methodology was grounded theory and the adolescents' perceptions were analyzed in the framework of symbolic interactionism. Three types of vegans were identified: the Conformed Vegan, the Organized Vegan, and the Individualistic Vegan. The decision to become a vegan was reported to be influenced by perceived internal reasons such as ethics, health, distaste for meat, and preference for vegetarian food. In addition, friends, family, school, media, and music influenced the decision to become a vegan. The perceived consequences of becoming a vegan were positive as well as negative and differed between the three types of vegans. Veganism as a new type of status passage with specific characteristics was illustrated. No modifications or new properties were discovered that add to the theory of status passage which indicates that the general model is applicable also in a vegan context.

O-GlcNAc cycling mediates energy balance by regulating caloric memory
- 2021

- Caloric need has long been thought a major driver of appetite. However, it is unclear whether caloric need regulates appetite in environments offered by many societies today where there is no shortage of food. Here we observed that wildtype mice with free access to food did not match calorie intake to calorie expenditure. While the size of a meal affected subsequent intake, there was no compensation for earlier under- or over-consumption. To test how spontaneous eating is subject to caloric control, we manipulated O-linked β-N-acetylglucosamine (O-GlcNAc), an energy signal inside cells dependent on nutrient access and metabolic hormones. Genetic and pharmacological manipulation in mice increasing or decreasing O-GlcNAcylation regulated daily intake by controlling meal size. Meal size was affected at least in part due to faster eating speed. Without affecting meal frequency, O-GlcNAc disrupted the effect of caloric consumption on future intake. Across days, energy balance was improved upon increased O-GlcNAc levels and impaired upon removal of O-GlcNAcylation. Rather than affecting a perceived need for calories, O-GlcNAc regulates how a meal affects future intake, suggesting that O-GlcNAc mediates a caloric memory and subsequently energy balance.

- Fruit, vegetables, cereals, and olive oil are common elements of the Mediterranean diet (MD), but each country in the Mediterranean basin has its own gastronomic customs influenced by socio-cultural, religious, and economic factors. This study compared the dietary habits of three Mediterranean populations with different cultures and lifestyles, a total of 600 adults (61.9% females) between 25 and 70 yrs from Spain, Morocco, and Palestine. All participants completed a self administered questionnaire, including sociodemographic and anthropometric items, a validated semi-quantitative food frequency questionnaire adapted to the foods consumed in each country, and three 24-h recalls. MD adherence was estimated with the MD Serving Score (MDSS). All populations showed a moderate adherence to the Mediterranean dietary pattern. In comparison to the Palestine population, MDSS-assessed adherence to the MD was 6.36-fold higher in the Spanish population and 3.88-fold higher in the Moroccan population. Besides the country of origin, age was another predictive factor of MD adherence, which was greater (higher MDSS) in participants aged over 50 yrs than in those aged 30 yrs or younger. This preliminary study contributes initial data on dietary differences between European and non-European countries in the Mediterranean basin. The Spanish diet was shown to be closer to MD recommendations than the diet of Morocco or Palestine. Given the impact of good dietary habits on the prevention of chronic non-transmittable diseases, health policies should focus on adherence to a healthy diet, supporting traditional dietary patterns in an era of intense commercial pressures for change.

- The objective of this study was to describe the association between meal pattern and obesity. The study is based on data from the INTERGENE research programme, and the study population consists of randomly selected women and men, aged 25-74, living in the V?stra G?taland Region in Sweden. A total of 3610 were examined. Participants with measured BMI>/=30 were compared with others (BMI<30) with respect to questionnaire data on habitual meal patterns and intake of energy estimated from food frequencies and standard portions. Odds ratios (OR) with 95% confidence intervals were adjusted for age, sex, smoking and physical activity in logistic regression models. Being obese was significantly associated with omitting breakfast, OR 1.41 (1.05-1.90), omitting lunch OR 1.31 (1.04-1.66) and eating at night OR 1.62 (1.10-2.39). Obesity was also related to significantly larger self-reported portion sizes of main meals. No statistically significant relationship with intake of total energy was revealed. Thus, the results indicate that examination of meal patterns and portion sizes might tell us more about obesogenic food patterns than traditional nutrient analyses of food frequencies. Being obese was associated with a meal pattern shifted to later in the day and significantly larger self-reported portions of main meals.

Perceptions and experiences of eating alone among community-living retired Swedes : Loss, routine and independence
- 2023

Tidskriftsartikel (refereegranskat)abstract
- The practice of eating together, commensality, is often considered as something positive in later life, particularly regarding peoples' nutritional status and psychosocial well-being. Eating alone, in contrast, is treated as a risk factor, although literature indicates that it is not necessarily something negative. Still, analyses that specifically target older peoples' varied experiences and notions of eating alone are scarce. This study has explored perceptions and experiences of eating alone among older people in Sweden, a country considered highly individualistic, yet with relatively low levels of loneliness in the older population. Semi-structured interviews were conducted with 20 community-living and retired Swedes, 70-90 years of age. A thematic analysis identified three themes: i) 'Eating alone as a manifestation of loss'; ii) 'Eating alone as an everyday routine'; and iii) 'Eating alone as independence and contentment'. General perceptions of eating alone were often related to the current living situation (e.g., cohabiting or single-living). One key finding was an identified tension between the idea of eating alone as something problematic among those living and eating with a partner and the practical experience of an uncomplicated routine among those living and eating alone. Eating together is discussed as a possible social need for many, but perhaps not for all. Some can feel content with eating alone or even enjoy it. Future studies should approach potential disadvantages of eating alone among older people as an open empirical question that is likely to depend on both the individual and the cultural context.

"He just has to like ham" : the centrality of meat in home and consumer studies
- 2015

- This study aimed to describe Discourses on meat in the school subject Home and Consumer Studies in five different northern Swedish schools. Fifty-nine students and five teachers from five different schools were recorded and in some cases video-taped during lessons. Results indicate that meat was seen as central to nutritional health, sensory experience, culture and social relationships. This positive view was challenged by an alternative Discourse where meat was threatening to health, sensory experience and psychological comfort, but this was not strong enough to affect centrality. Even when participants sought to promote the health advantages of reducing meat consumption, the dominant centrality Discourse was strengthened. This implies that the possible tension between physical and psychosocial/emotional health can make the benefits of a reduction difficult both to convey and accept. A form of critical food literacy may help teachers deconstruct the arbitrary power of the centrality Discourse, but it may also strengthen meat-eater identities because the social norms that guide food choice become salient. A redesign of Discourses might facilitate a reduction in meat consumption, but such a paradigm shift is dependent on the development of society as a whole, and can only be briefly touched upon within the limited timeframes and resources of Home and Consumer Studies.
