    The critical role of everyday practices in climate change mitigation has placed experimental approaches at the top of the environmental policy agenda. In this paper we discuss the value of behavioural approaches, practice theories, pragmatic tinkering and speculative thinking with respect to experimentation. Whereas the first two have been much discussed within sustainability science and transition research, the notions of pragmatic tinkering and speculative thinking radically broaden the scope of experimental research and its contribution to sustainable everyday practices. Pragmatism brings to the fore the need to coordinate multiple practices and understandings of good eating, as these may clash in practice. Through this lens, the value of experimental research lies in revealing frictions that need to be resolved, or tinkered, in practice. Speculative experimentation, in turn, refers to the power of experiments to challenge the experimental setting itself and force thinking about new possibilities and avenues. We investigate the value of all four approaches in relation to our experiments with sustainable eating in the Finnish and Nordic context. Our elaboration justifies the need to broaden the conception of experimental research in order to capture the multiplicity of sustainable eating. Hence, we call for attentive, speculative experimental research aimed not only at testing solutions for sustainable everyday practice, but also at reflecting on the practice of experimentation itself.

    Stress and other negative emotions, such as depression and anxiety, can lead to both decreased and increased food intake. The term 'emotional eating' has been widely used to refer to the latter response: a tendency to eat in response to negative emotions with the chosen foods being primarily energy-dense and palatable ones. Emotional eating can be caused by various mechanisms, such as using eating to cope with negative emotions or confusing internal states of hunger and satiety with physiological changes related to emotions. An increasing number of prospective studies have shown that emotional eating predicts subsequent weight gain in adults. This review discusses particularly three lines of research on emotional eating and obesity in adults. First, studies implying that emotional eating may be one behavioural mechanism linking depression and development of obesity. Secondly, studies highlighting the relevance of night sleep duration by showing that adults with a combination of shorter sleep and higher emotional eating may be especially vulnerable to weight gain. Thirdly, an emerging literature suggesting that genes may influence body weight partly through emotional eating and other eating behaviour dimensions. The review concludes by discussing what kind of implications these three avenues of research offer for obesity prevention and treatment interventions.

    Övervikt och fetma klassas numera som folksjukdomar och ökar risken för flera allvarliga sjukdomar, såsom hjärt- och kärlsjukdomar samt diabetes. Matlust och hungerkänsla är komplexa fenomen som styrs av flera olika regleringsmekanismer. Matlusten påverkas även av psykiska faktorer, och forskningen har under senaste åren visat att det finns gemensamma drag mellan substansberoende och tillstånd med obalanserat födointag. Eftersom övervikt är allt vanligare bland befolkningen, har flera läkemedel framställts för behandling av fetma. Flera av dessa har allvarliga biverkningar eller endast blygsam effekt. Därmed finns det ett stort behov för vidare utveckling av läkemedel som verkar via olika mekanismer som påverkar vår matlust och matassocierade beteendet. En stor del av forskningen har hittills fokuserat på ventral tegmental area (VTA) i mitthjärnan. Brevid VTA finns en annan kärna, laterodorsal tegmentum (LDT), som står för en stor del av inflödet till VTA. LDT har bevisats vara kopplat till uppkomst av beroende. Denna forskning hade som mål att utreda rollen av LDT i matlustregleringen genom att med DREADD-teknik aktivera och inaktivera kolinerga neuroner i LDT hos transgena möss och mäta mössens matintag både under normala förhållanden samt då DREADD-receptorerna är aktiverade och när de är inaktiverade. Dessutom ville vi utreda effekten av en föregående fasteperiod på resultaten. Då mössen genomgått en fasteperiod innan försöken kunde ingen effekt av LDT på matlusten påvisas. I försöken utan fasta ökade matlusten hos möss i Gq-gruppen då kolinerga neuronerna i LDT aktiverades med CNO. Detta område kräver ännu ytterligare forskning för att påvisa en klar effekt av LDT på matlust.

    The shift of society toward sustainable food culture requires collectively challenging meat and dairy-based diets and their role in current practices of eating. This study focuses on how discussions in social media can facilitate reconfiguration in eating. Three practice-theoretical perspectives - practices constituting of elements, eating as a compound practice, and communities of practice - afford us with analytical tools to investigate eating and how the constituting elements are negotiated and recrafted in social media discussions across the compound practice. As empirical data, we use altogether 14,250 social media messages on the Finnish Vegan Challenge campaign. By combining qualitative content analysis with topic modeling, we capture the various themes occurring in these discussions and their relation to changes in eating practices. The results show that within these discussions, social learning among peers covered the whole sphere of eating-related practices from production and distribution to purchasing and cooking vegan food, and to sharing stories and experiences of veganism. Our findings illustrate how these discussions can be seen as forming a reconfigurative community of practice, which can potentially support and facilitate social change of eating toward sustainability also outside the Vegan Challenge community.

    64-vuotias nainen oli huolissaan kuukausia vaivanneista ruokailuun liittyvistä oireista. Verenpaineen aaltoiluakin oli esiintynyt aiempaa enemmän. Naisella oli mm. verenpainetauti ja häneltä oli aiemmin hoidettu kolme syöpäsairautta. Ärtyvän suolen oireyhtymä naisella oli todettu jo nuoruudessa.
