Journal article (peer-reviewed)abstract
- This study investigates how framing in relation to environmental consequences directs consumers to prioritize among gain, hedonic, and normative goals when accepting suboptimal food to reduce food waste. A random sample of 1,704 United States consumers completed a three-wave survey instrument, including repeated discrete choice experiments. Goals related to gains deteriorated substantially over time. Goals for reducing environmental impact by purchasing sub-optimal food were stronger and more time-invariant. There was no increase in goal strength for reduce environmental impact due to the type information provided. Furthermore, there was no support for a lower decrease across time in normative goal strength due to exposure to positive framing. There were combined effects of information and time, respectively. Five latent groups were identified. These results are relevant for actions to increase the acceptance of suboptimal food, finding that differences in consumer preferences are attributable to goal type and goal strength.

In: Clinical Physiology and Functional Imaging. - : Wiley. - 1475-0961 .- 1475-097X. ; 36:2, s. 146-154

Journal article (peer-reviewed)abstract
- Assessment of image analysis methods and computer software used in Tc-99m-MAG3 dynamic renography is important to ensure reliable study results and ultimately the best possible care for patients. In this work, we present a national multicentre study of the quantification accuracy in Tc-99m-MAG3 renography, utilizing virtual dynamic scintigraphic data obtained by Monte Carlo-simulated scintillation camera imaging of digital phantoms with time-varying activity distributions. Three digital phantom studies were distributed to the participating departments, and quantitative evaluation was performed with standard clinical software according to local routines. The differential renal function (DRF) and time to maximum renal activity (T-max) were reported by 21 of the 28 Swedish departments performing Tc-99m-MAG3 studies as of 2012. The reported DRF estimates showed a significantly lower precision for the phantom with impaired renal uptake than for the phantom with normal uptake. The T-max estimates showed a similar trend, but the difference was only significant for the right kidney. There was a significant bias in the measured DRF for all phantoms caused by different positions of the left and right kidney in the anterior-posterior direction. In conclusion, this study shows that virtual scintigraphic studies are applicable for quality assurance and that there is a considerable uncertainty associated with standard quantitative parameters in dynamic Tc-99m-MAG3 renography, especially for patients with impaired renal function.

Consumer perceptions and attitudes towards climate information on food
- 2022
-
In: Journal of Cleaner Production. - : Elsevier BV. - 0959-6526 .- 1879-1786. ; 370
-
Journal article (peer-reviewed)abstract
- The food sector is a major contributor to climate change, and reducing meat consumption is important to achieve significant reductions in global carbon emissions. The implementation of information policies to reduce carbon emissions from red meat consumption entails understanding of how such information is expected to be received and used by consumers. This study uses survey data from a consumer panel, and match this with data on the same respondents' actual purchase behavior based on scanner data. Individuals with lower knowledge levels about the climate impact from food purchase the highest share of red meat, and the lowest share of sustainability labelled products. This indicates that information provision has the potential to increase knowledge among in-dividuals with the highest climate impact. Four sub-groups of consumers are identified in a latent class cluster model based on their motivations for consuming or avoiding meat. It is mainly the 'meat reducers' and 'meat avoiders' that are interested in using climate information when purchasing food. However, individuals in these sub-groups already purchase the least amount of meat and the highest amount of sustainable products. These findings point to limitations with climate information as a policy instrument, and suggests that other measures are needed as complements to initiate and achieve the necessary changes in consumption patterns.

Dietary changes based on food purchase patterns following a type 2 diabetes diagnosis
- 2022
-
In: Public Health Nutrition. - 1368-9800 .- 1475-2727.
-
Journal article (peer-reviewed)abstract
- Objective: The study explores whether type 2 diabetes (T2D) diagnosis affects food consumption patterns in line with the dietary recommendations provided to individuals in relation to a diagnosis. Design: Based on detailed food purchase data, we explore which dietary changes are most common following a T2D diagnosis. Changes are investigated for several energy-adjusted nutrients and food groups and overall adherence to dietary guidelines. Setting: We use data on diagnosis of T2D and hospitalisation in relation to T2D for a sample of adult Danes registered in the official patient register. This is combined with detailed scanner data on food purchases, which are used as a proxy for dietary intake. Participants: We included 274 individuals in Denmark who are diagnosed during their participation in a consumer panel where they report their food purchases and 16 395 individuals who are not diagnosed. Results: Results suggest some changes in dietary composition following diagnosis, as measured by a Healthy Eating Index and for specific food groups and nutrients, although the long-term effects are limited. Socio-economic characteristics are poor predictors of dietary changes following diagnosis. Change in diet following diagnosis vary with the pre-diagnosis consumption patterns, where individuals with relatively unhealthy overall diets prior to diagnosis improve overall healthiness more compared to individuals with relatively healthy diets prior to diagnosis. Conclusions: Adherence to dietary advice is low, on average, but there is large variation in behavioural change between the diagnosed individuals. Our results stress the difficulty for diagnosed individuals to shift dietary habits, particularly in the long term.

Is food labelling effective in reducing climate impact by encouraging the substitution of protein sources?
- 2021
-
In: Food Policy. - : Elsevier BV. - 0306-9192 .- 1873-5657. ; 101
-
Journal article (peer-reviewed)abstract
- This study investigates consumer willingness to substitute high-emissions meat products with lower-emissions protein products, including blends of meat and vegetables. Survey data, including a choice experiment, are combined with data on the respondents' actual purchase behaviour. The traffic light carbon label has an effect on choice behaviour, as it increases the willingness to purchase lower-emissions protein products such as chicken and meat substitutes. We further find that the willingness to purchase these lower-emissions products is largest among individuals who are already purchasing most sustainably. We discuss policy implications from the expected impacts of carbon labels, and how such labels affect different types of consumers.

Interested, indifferent or active information avoider of climate labels: Cognitive dissonance and ascription of responsibility as motivating factors
- 2020

Other publication (other academic/artistic)abstract
- Active avoidance of information is gaining attention in behavioral sciences, and recently also its’ relevance from an economic theory perspective. We explore motivations and policy implications of active avoidance of carbon emission information. In a stated preference survey respondents were asked to indicate if they wished to access carbon emission information (info-takers) or not (info-decliners) when selecting protein source in a first stage. In a second stage all respondents were provided carbon emission information. The info-takers reduced their CO2-emissions from their food choices with 32%, while the info-decliners also reduced their CO2 emissions (12%). This provides evidence of active information avoidance among at least some info-decliners. We explore cognitive dissonance and responsibility feelings and personal norms as motivations for actively avoiding carbon emission information on meat products, and how these motivations affect the reaction if imposed information. Our results show that carbon emission information increases choice task uncertainty most among individuals that experience climate related cognitive dissonance and/or responsibility feelings. These findings point to the potential of carbon emission information as a measure for changing food consumption towards less carbon emitting products. The study also highlights the importance of how the information is provided and presented.

- Active avoidance of information is gaining attention in the behavioural sciences. We explore motivations for active avoidance of carbon emissions information. In the first stage of a stated preference survey, respondents indicated whether they wished to access carbon emissions information (info-takers) or not (info-decliners) when selecting a protein source. In the second stage, all respondents were provided with carbon emissions information. The info-takers reduced emissions from their food choices by 32%, while the info-decliners also reduced their emissions (by 12%). This indicates active information avoidance among at least some info-decliners. We explore how cognitive dissonance, responsibility feelings and personal norms affect a person's actions when information is imposed upon them, and their role as motivators for actively avoiding carbon emissions information on meat products. Individuals who experience climate-related cognitive dissonance and/or responsibility feelings change behaviour more following climate information, and it also increases choice task uncertainty mostly among these. These findings point to the potential of increasing impact from information by simultaneously increasing personal responsibility feelings and activating social norms.

The future of carbon labeling - Factors to consider
- 2023

In: Agricultural and Resource Economics Review. - : Cambridge University Press. - 1068-2805 .- 2372-2614. ; 12:120

Journal article (peer-reviewed)abstract
- Compared to other policy instruments that aim to change consumer behavior, information provision is perhaps the least controversial. An important question is how information in the form of carbon labels can contribute to direct food consumption toward reduced climate impact. From a policy guidance perspective, there is a need to identify how the labeling strategy affects consumers' ability to identify lower emitting food products and the behavioral change due to carbon information. Key aspects of a carbon label are discussed, as well as the implications of different labeling schemes. Drawing on economic and behavioral theories, we propose that, to assist consumers in identifying changes in consumption that contribute to significant reductions in their climate impact, a carbon label must enable comparisons between product groups and not only within narrowly defined product groups. This suggests mandatory labeling, since producers of high-emission products are less likely to display such labels. However, it is important to consider both costs and benefits of labeling schemes and to consider complementing labeling with other policy instruments. © The Author(s), 2023.
