    • The age-related decline in olfactory function is well established and concerns intensity perception and odor identification. However, the extent to which olfactory decline influences food preferences is less clear. Furthermore, it is unclear whether there are decline patterns relating to food odors, specifically. This study investigated intensity perception and hedonic liking for 14 multi-component food odors and one pure odorant in three groups of older adults (age 60–69, age 70–70, age 80 + ) and a group of young adults. In total 335 subjects were tested, 246 old and very old adults and 89 young adults. The age group 60–69 was on par with the young adults, whereas intensity perception declined for the majority of odors for older adults age 70–79 and the very old age 80 + . The largest drop in intensity perception was seen for savory odors; fried meat, mushroom and onion. In contrast, intensity perception for raspberry and orange did not differ between groups of older adults and young adults. Hedonic liking decreased to some degree with increasing age but remained largely the same for savory odors (bacon, mushroom, fried meat and onion). A decline in liking was seen for coffee and thyme. This study shows evidence that age-related decline in intensity perception is food odor specific and some aggregation may occur at a higher concept level for the “savory” category. Furthermore, hedonic liking is not necessarily dependent on the intensity perception as seen for several odors, where declining intensity perception did not impact hedonic liking. This could be explained by changes in dose-response relationships for the group of ageing individuals, which in fact may favor persistence of the food odor liking, despite a decline in their intensity perception.

  • Familiarity and recognition of everyday food odours in older adults and influence on hedonic liking
  • 2022

    • In an aging population, changes in sensory abilities can adversely affect enjoyment of a meal. Age-related changes in identification ability and familiarity of food odors may influence food intake since some foods become less recognizable and attractive, which may affect the individual’s health and nutritional condition. The aim of this study was to examine age-related changes in familiarity and the ability to correctly identify everyday food odors in older adults. We also aimed to establish the relationship between these changes and hedonic liking of food odors compared to young adults. The study included 335 participants, 246 older adults and 89 young adults. A positive relationship between familiarity and liking was observed across all food odors. Familiarity and odor identification ability declined with increasing age. The most significant loss in the ability to identify odors was observed for curry, fried meat, and toasted bread, while both age groups identified banana, orange, and vanilla equally well. For older adults with a diminished perception of familiarity and a reduced ability to identify odors correctly, increasing the concentration of the odor improved familiarity and enhanced their ability to identify odors. Our findings support the notion that the familiarity of food odors is an important parameter for the appreciation of food in older adults.

  • 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.
