- Background & aims: Children's food choices are guided by their preferences. It is established, however, that repeated exposure to a novel food increases children's acceptance. This study investigated how acceptance of an initially liked and disliked snack bar develops in 9-11 year-old children. Methods: 315 children were randomised into three groups: A control group (n = 111) and two groups exposed to an initially liked kamut bar (n = 94) and an initially disliked sea buckthorn bar (n = 110). Acceptance of both bars was tested before and after the exposure period, and on the 9th exposure. Results: Intake of both bars increased significantly in the exposure groups. There was no difference in the control groups' intake or liking of the bars between pre and post-testing. Liking rose significantly for children exposed to the disliked sea buckthorn bar, while this was not observed in children exposed to the liked kamut bar. In a post-test children exposed to kamut bars had higher intake of that bar than non-exposed children. This was also observed for the sea buckthorn bar that was also given significantly higher liking scores by the exposure group. Conclusions: The majority of children exposed to an initially disliked bar increase acceptance after nine exposures to the same level as an initially liked bar. Children repeatedly exposed to a liked bar show stable acceptance.

- In several studies, it has been found that repeated exposure to a novel food increases children’s acceptance of the exposure food. The present study, investigated how repeated exposure influences the acceptance of two Nordic berry juices, and whether the development depends on initial liking of the product, in 9–11 year-old children. The study had 317 participants. Two groups of children were exposed to either sea-buckthorn (n = 92) or aronia (n = 105) juice eight times, and performed two follow-up sessions 3 and 6 months after the 8th exposure. A third group (n = 120) served as controls. During pre and post-test sessions all participating children evaluated acceptance of both juices.Intake of sea-buckthorn juice increased significantly over the eight exposures (55.1 ± 7.3 till 108.8 ± 12.3) and remained high after 6 months (131.1 ± 13.2). Intake of aronia juice was only increased at follow-up sessions. Liking did not develop significantly for any of the juices across exposures. When children were grouped by their initial liking increased intake across exposures was observed regardless of initial liking of sea-buckthorn. Liking developed similarly for both juices. A significant increase was found for the ‘initial dislikers’ only. This study demonstrates how exposure effects are influenced by initial liking; it appears that changes in familiarity explain the changes seen for sea-buckthorn among ‘dislikers’. ‘Initial dislikers’ had the most benefit from repeated exposures, but did not reach ‘initial likers’ across eight exposures; more exposures in the group of ‘initial dislikers’ had possibly led to even higher liking and intake. The increased intake observed for ‘neutral likers’ and ‘initial likers’ of sea-buckthorn was not explained by increased familiarity or increased liking.

- The acceptance of novel foods by children is related to a number of factors, and differences in taste sensitivity may form some specific challenges. High sensitivity might be a barrier to the acceptance of sour/bitter products by children. This study investigated the effect of sensitivity to bitter, sour, sweet, and salty tastes on the acceptance of Nordic juices in 9- to 11-year-old children. A total of 328 children were subjected to two taste sensitivity tests for quinine, citric acid, sucrose, and NaCl. Their acceptance of six juices (carrot, rosehip, sea-buckthorn, lingonberry, grapefruit, and aronia) was measured. Bitter sensitivity was found to be significantly correlated to the intake of the sweet sea-buckthorn and lingonberry juices; the most bitter-sensitive children exhibited the highest intake of these juices. The opposite relationship was found for bitter sensitivity and the intake of the bitter grapefruit juice. Sour, sweet, and salt sensitivities did not affect the intake of any of the juices. Liking scores were not affected by sensitivity. In conclusion, bitter sensitivity appears to influence food intake in children to a greater extent than sour, sweet, or salt sensitivity. Bitter-sensitive children exhibited a reduced intake of grapefruit juice and a higher intake of sucrose-sweetened juices. Thus, bitter sensitivity might be a challenge in the acceptance of certain bitter foods.

- Key findings:• Climate change is impacting the subsistence harvestbased livelihoods of many small Arctic communities, affecting the quality or supply of traditional food and drinking water, including availability of species to be harvested, and altering transportation access.• Rain-on-snow, extreme snowfall, and variable freezethaw cycles have resulted in severe impacts for reindeer herders. In 2020, multiple snowstorms combined with a late spring thaw resulted in high newborn calf mortality and, together with other social stresses related to Covid-19, created severe crises for reindeer herders in Fennoscandia.• Commercial fisheries are expanding in Arctic shelf ecosystems with warmer oceans and less sea ice. This could benefit local economies and job creation, but may also challenge traditional livelihoods and culture and impact vulnerable Arctic ecosystems. Large uncertainties are associated with the effects of ocean acidification, which could potentially counteract increased commercial fishing opportunities. Commercial fishing is currently prohibited by international agreement in the Central Arctic Ocean.• Warmer water is enabling a northward expansion of salmon farming in the ice-free European Arctic. The aquaculture industry brings employment opportunities and positive ripple effects for local economies, but also has environmental and societal costs that need to be considered in marine spatial planning and regulatory measures.• Arctic cruise tourism is increasing and is attracted to the wildlife associated with the marginal ice zone. Although increased cruise tourism brings the potential for local economic development, adverse local impacts have been reported, including impacts on culture, local hunting and fishing, crowding, and revenue largely benefitting foreign-based individuals and corporations.• Permafrost thaw, flooding, and coastal erosion are causing damage to buildings, roads, and other infrastructure, and pose serious financial and health risks to Arctic residents.• Wildfire occurrence near populated regions in North America and Sweden, and throughout Siberia, in the past five years has resulted in significant economic loss from property damage as well as physical and mental health impacts.• Fishing, cruise tourism, and increased oil and gas operations near the marginal ice zone could increase demand on search and rescue operations and may represent a considerable risk for vulnerable ecosystems. The extent of ice cover is important for determining the fate of an Arctic oil spill and research indicates longer term and more severe ecological impacts from oil spills in the Arctic than in other regions.• Understanding and studying integrated socio-ecological systems, including cumulative and cascading impacts, is important not only in terms of research, but also in terms of risk mitigation, hazard response, climate adaptation,
