Improving sensory quality of food product to meet the elderly’s preferences: which winning strategy?
2014
Having a "good" diet counts as an important factor for healthy ageing. Beyond nutritional aspects, a "good" diet, also contributes to maintain “eating pleasure”, an essential component in food intake mechanism. The present study aims to assess the impact of changes related to texture, taste and flavor on food acceptance in the elderly. The adopted strategy was to orientate the products modifications based on elderly’s expectations. A qualitative approach (focus group and face-to-face interviews) was carried on with a first elderly panel (>65 yo) to collect suggestions about sensory improvements that can be made in a meat dish with a normal texture, in a meat dish with a modified texture and…

Food selectivity and pickiness in adulthood: an age and gender-related behaviour?
2013
Food pickiness –or selectivity- is a behavior which may lead to a lack of variety and an unbalanced diet. While this trait has been studied in children, pickiness in adults has been more rarely explored and only recently in French elderly1. The first aim of the present work was to identify if pickiness varies according to age and gender in adults. The second aim was to examine the link between the selectivity score and self-reported degree of pickiness. Four hundred French adults from 25 to 75 years old answered an online survey. Respondents were asked to tick each food they dislike among a list of 71 food items. The selectivity score was the number of disliked food items1. Moreover, partic…

2012
Introduction et but de l'étudeUne “bonne” alimentation est considérée comme l’un des facteurs clefs contribuant à la prévention des pathologies survenant avec l’âge. Mais une “bonne” alimentation, ce n’est pas uniquement satisfaire aux besoins nutritionnels de la population âgée. C’est aussi maintenir le plaisir à manger, composante essentielle de la régulation de la prise alimentaire et plus généralement du bien-être et de la qualité de vie (Grunert et al, 2007). Lors d’une enquête menée auprès de personnes âgées de plus de 65 ans, nous avons interrogé 289 personnes vivant à domicile sans aide et 95 personnes vivant en Établissement pour Personnes Âgées Dépendantes (EHPAD). Les résultats o…
Food pickiness in the elderly: Relationship with dependency and malnutrition
2014
Special Issue: 5th European Conference on Sensory and Consumer Research (Eurosense) 2012 "A sense of inspiration"; International audience; Among factors contributing to malnutrition in the elderly, the present study aimed at assessing the impact of food selectivity (also referred as food "pickiness") on the nutritional status of the elderly. A survey with 559 French people over 65 years old was conducted to collect data on food selectivity, dependency and nutritional status. Food selectivity was assessed by asking respondents to tick each food they dislike among a list of familiar foods. Since some foods could be ticked as disliked because elderly people experience physical difficulties in …
Home-Delivered Meals: Characterization of Food Intake in Elderly Beneficiaries
2021
Objective. In this study, we focus on elderly people (≥70 years old) benefiting from a home delivery meal service as part of a social welfare program. We aimed to: (i) assess the gap between the recommended and actual nutritional intake in this population and (ii) study the relationship between the intake of nutrients and the variables characterizing the participants’ health and nutritional status. Design. A dietary survey (24-hour record) was conducted during a home interview, with 64 people receiving a home delivery meal service (75% women
Food behaviour and health patterns in the French elderly population
2013
With an aging population in Europe, understanding why frailty occurs earlier or later depending on individual characteristics is a strong challenge. Few studies have investigated food behavior and the link with nutritional status among French elderly. In Aupalesens survey, we aimed to identify the link between malnutrition and health, sensory, sociological, psychological, food behavior and preferences. 559 women and men older than 65 years old were enrolled. Typical profiles were identified using a double clustering approach aiming to reduce both observations and variables complexity (CDPCA, Vichi & Saporta, 2009). A partition of the 55 multidisciplinary items into four groups was retained,…

Sensory testing in new product development: Working with older people
2015
Very few studies today validate the use of various sensory tools among elderly subjects, although the population is ageing rapidly. This chapter deals with applied sensory assessment in the food sector. It first presents heterogeneity factors in this population: physical and psychological health and dependency, decrease of chemosensory capacities, changes in oral-motor skills and modifications of cognitive abilities. Then, a study aiming at comparing the capacity of young and more or less dependent elderly subjects to use a discrete scale (discriminatory power and repeatability) in a monadic sequential presentation is described. Finally, recommendations are given about the cases where a pan…
Consumer testing in elderly population: impact of age and dependence on liking scoring
2012
In this beginning of XXI° century, there is a total of 600 millions of elderly in the world, and this population should reach 2 milliards in 2050. In such a context, growing interest is devoted to this population, both from an economical and a societal point of view. A key challenge is to promote healthy ageing, a nutritious diet being considered as an important factor to assist elderly in maintaining optimal level of health and preventing the onset of disease or dependency. As ageing is accompanied by physiological and psychological changes, that may alter food perception and preferences. Developing nutritious food likely to meet preferences of older people requests consumer testing with t…
Evidence for different patterns of chemosensory alterations in the elderly population: impact of age versus dependency
2015
The present experiment aimed to explore the interindividual variability in chemosensory abilities among the elderly population. The chemosensory abilities of 559 subjects, aged from 65 to 99 years, were evaluated. Various categories of the elderly, including people who were living at home either without or with assistance, and people who were living in a nursing home, were interviewed. The results revealed that 43% of the sample presented well-preserved chemosensory abilities, whereas 21% of the participants presented a moderate impairment. Of the sample, 33% presented well-preserved olfactory abilities but strong impairment in gustatory abilities and 3% were nearly anosmic but remained abl…

Evolution de la perception sensorielle et des préférences alimentaires chez les personnes âgées : quel lien avec le statut nutritionnel ?
2012
Le processus de vieillissement, même lorsqu’il se déroule normalement, est associé à de nombreuses modifications d’ordre physiologiques (ralentissement du transit intestinal, du métabolisme basal, perte de dents, altérations des capacités chimiosensorielles), psychologiques (solitude, dépression, démence) et sociologiques (retraite, veuvage, déménagement…) susceptibles d’avoir un impact sur la prise alimentaire et le statut nutritionnel de la personne âgée. Au-delà de ces changements, l’apparition d’une dépendance pour l’alimentation, qui fait généralement suite à une perte d’autonomie de la personne (apparition d’une incapacité physique ou psychique, veuvage…), modifie en profondeur le rap…
Âge, perception chimiosensorielle et préférences alimentaires
2010
Revue non indexée dans le JCR.; National audience; Le vieillissement s’accompagne d’un déclin des sensibilités olfactives et gustatives (sensibilités chimiosensorielles). Or, lorsque nous mangeons, la saveur et l’odeur d’un aliment contribuent largement au plaisir associé à son ingestion. Plusieurs auteurs ont fait l’hypothèse que le déclin des capacités chimiosensorielles observé chez les seniors conduirait à des modifications des préférences alimentaires, celles-ci entraînant à leur tour des changements de l’appétit et de la prise alimentaire. Effectivement, lorsque les préférences sont mesurées à un instant t, les seniors tendent à préférer des aliments ayant une flaveur plus intense. C…
Tell me what you are eating, I will tell you who you are: The different eater styles among the elderly population
2012
National audience; Fish or rare steak? Fruit or pastry? Soup and ham or roast and dessert?... In order to explore the favourite meal of the elderly, a large survey was conducted including 559 people older than 65 (AUPALESENS survey). Different categories of elderly were interviewed, including people who are living at home either without any assistance or with assistance, and people who are living in a nursing home.Each respondent completed a questionnaire designed to explore three dimensions, namely meal content, eater style and pickiness. Regarding meal content, respondents were asked to choose among broad categories of dishes (e.g., salad, soup, roast, stew, veggies, cheese, fruit, pastry…

Adapter un portage de repas à l'appétit et à l'état nutritionnel de personnes âgées dépendantes : une étude clinique de 4 mois
2020
Avec l'âge, la capacité des personnes âgées à réaliser les tâches du quotidien, notamment celles reliées à l'alimentation (courses, préparation des repas), peut être altérée. En France, face à cette situation, de plus en plus de personnes âgées font appel à des services de livraison de repas à domicile. Les objectifs de cette étude sont de caractériser le statut nutritionnel des personnes âgée, faisant appel à ce type de service et de mesurer l'impact d'une intervention nutritionnelle adaptée, en personnalisant leur livraison de repas à leurs besoins. 64 personnes âgées, bénéficiant d'une livraison de repas à domicile ont été recrutés et répartis au hasard dans un groupe expérimental (n=32 …
Amélioration des repas et variété : Quel impact sur la prise alimentaire et le plaisir des seniors dépendants ?
2013
National audience; Introduction et but de l'étude: S’alimenter est un acte indispensable à la vie qui fait intervenir l’ensemble de nos fonctions sensorielles. Au-delà de ces fonctions, nous apprécions, aussi, davantage un repas lorsque le plat est à notre goût ou lorsqu’il est présenté avec soin et avec de la variété. Au cours de l’avancée en âge, pathologies et dépendance constituent des facteurs de dénutrition importants (HAS 2007) et augmentent le risque de placement en institution. En collectivité, le libre choix disparait ce qui peut réduire sensiblement le plaisir des repas. L’objectif du travail était d’identifier des leviers pour lutter contre la problématique nutritionnelle du suj…
