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…

Feeling good! Consumers' associations to feeling good related to food, personal care and home-care products in 14 countries worldwide
2017
International audience; Interest in understanding how consumer goods contribute to perceived wellbeing has increased rapidly in recent years. This study investigates consumers' associations to feeling good (FG), as well as FG related to food, personal care and home-care products. Worldwide consumers from 5 continents, 14 countries and 10 languages (N=9,868, n=588-800 per country) responded to a web-based free word association test in February 2016. To ensure culturally representative answers, only respondents declaring having lived in their country their whole life were selected for the survey. The task started with the elicitation of four words associated to FG. Then, successive sections i…

The nutritional issue in older people with home-delivered meals: a scoping review protocol
2020
Setting up a home-delivered meal service often allows older people suffering from physical and/or cognitive disabilities to stay at home. However, older people who delegate their food activities (food purchasing, cooking…) have been reported to have a worse nutritional status than people who take care themselves of their food activities. In this context, we will conduct a scoping review of all studies related to the nutritional issue in home-delivered meal older recipients. This review was expected i. to shed light on the nutritional status of older people who benefit from home-delivery service to better understand their needs, and ii. to evaluate if home-delivered meal service can be a rel…
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…
Proximal versus distal contextual factors: which impact on meal pleasure and food intake in the elderly living in a nursing home?
2014
Poster présenté lors de la conférence; Introduction: Several authors pointed out the importance of meal context on food intake in nursing home. Some authors assessed the impact of context improvement on food intake in nursing home, but they assessed ‘holistic’ strategies by improving physical environment, increasing choice level, changing staff organization… (Abbott et al. 2013). Despite some of these interventions were effective, these strategies are costly and thus difficult to be implemented in nursing home. The aim of the present experiment was to assess the impact of single contextual factors, three proximal factors (food contextual factors) and three distal factors (non-food contextua…

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…

Impact d'une odeur non consciemment perçue sur des choix alimentaires
2013
Présentation orale (résumé de 2 p.); Bien qu'il ait été longtemps considéré que nous étions pleinement conscients des motivations guidant nos comportements, les recherches actuelles en psychologie et en économie suggèrent qu'en matière de choix, nous ne sommes pas les êtres rationnels que nous pensons être (Dijksterhuis et al., 2006; Kahneman & Tversky, 2000). Les choix correspondent en fait à des processus complexes d'intégration, qui ne sont pas seulement rationnels, mais surtout basés sur des sentiments, des émotions et des souvenirs (Loewenstein et al., 2001). En outre, il est maintenant bien établi en psychologie qu'une part significative des comportements et choix sont influencés par …

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,…

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…

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…

Comme l’ont montré plusieurs travaux, l’entrée en Etablissement d’Hébergement pour Personnes Agées Dépendantes (EHPAD) s’accompagne d’une augmentation du risque de dénutrition (HAS, 2007 ; Sulmont-Rossé et al., 2012). Parmi les facteurs susceptibles d’affecter la prise alimentaire, il a été montré que l’environnement qui entoure le repas (de l’assiette à l’ambiance générale) contribuait fortement à l’appétit et à la prise alimentaire des résidents d’EHPAD (Nieuwenhuizen et al. 2009 ; Nijs et al. 2009). De fait, quatre études ont montré qu’une amélioration globale de l’environnement (changement de mobilier, décoration de la salle à manger, réorganisation du personnel…) pouvait entrainer une …
Providing choice and/or variety on vegetables: What impact on food intake?
2015
On the one hand, a choice situation gives an individual a sense of freedom, autonomy and control over the environment, which triggers higher intrinsic motivation and higher satisfaction (Deci and Ryan, 1985). Indeed, it has been demonstrated that a choice situation elicits higher food intake in a meal context (Rohlfs Domínguez et al., 2013; Parizel et al., 2015). On the other hand, providing variety has been demonstrated to enhance food intake. Rolls et al. (1981) argued that providing variety during a meal prevents the onset of specific sensory satiation which refers to the declining satisfaction generated by the monotonous consumption of a certain food. However, in an out-of-home catering…

Impact of a non-consciously perceived odour on subsequent food choices
2013
Poster (1 page) ; http://www.pangborn2013.com/; International audience; Although people were initially considered as entirely conscious of the motivations driving their behaviour and choices, current research in psychology suggests that a significant part of choices and decision-making is influenced by unconscious processes (Bargh, & Chartrand, 1999; Dijksterhuis et al., 2005). To study the unconscious processes involved in food choice, we used the priming paradigm. In a first experiment, we showed that non-consciously perceived fruity odours impacted intentions of food choices (on a menu card), guiding participants toward more fruit and/or vegetable (Gaillet et al., under review). The pres…
Quand les odeurs influencent les choix alimentaires : impact d'un amorçage olfactif

Techniques culinaires et confort en bouche chez la personne âgée
2020
Culinary processes and food comfortability in an older population Aging is often accompanied by oral impairments, including the loss of teeth and a decline in saliva flow. These changes can lead older people to avoid the consumption of foods that are difficult to chew such as meat. This may consequently increase the risk of sarcopenia (loss of muscle mass, strength and performance) as well as the risk of protein-energy undernutrition in this population. In order to compensate the decline in oral health observed in older individual and to maintain meat consumption, we assessed the impact of four culinary processes (cooking bag, tenderizer, marinade and low-temperature cooking) on the percept…

Influence du caractère onctueux sur la perception de la flaveur dans des crèmes desserts
2005
National audience; La texture, la saveur et l’arôme sont les composantes majeures de l’acceptabilité des aliments par les consommateurs. De nombreuses études menées sur ces composantes deux à deux ont montré que la modification de l’une d’elles peut influencer la perception d’une autre, par des interactions de type physico-chimique et/ou sensoriel. L’originalité de notre approche a été de comprendre comment, dans une matrice alimentaire complexe type crème dessert, la texture (l’épaisseur), la saveur et l’arôme pouvaient interagir ensemble et influencer le caractère onctueux de ce type de produit. Trois matrices de texture variable ont été formulées à partir d’une même composition de base. …

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…

Texture-aroma interactions in dairy products: Do in-vivo and in-vitro aroma release explain sensory perception?
2008
International audience; The influence of the texture on perceived aroma intensity and on in-vivo and in-vitro aroma release was investigated on three types of dairy products, prepared with different textures. Aroma release depends on in mouth breakdown of the product. The consequences of a textural modification on aroma perception were not the same for the different products. In the case of liquid to semi-liquid products (yogurt and custard dessert), in-vivo aroma release decreased when viscosity increased. For firm gels (model cheeses) in-vivo aroma release was found to increase when cheese hardness increased, but inverse results were obtained in in-vitro conditions. Thus, aroma release co…

National audience; Introduction et but de l'étude : S'il existe un certain nombre d'études ayant décrit les consommations alimentaires au sein de la population française dans différentes classes d'âge (eg, étude INCA3, 2017, pour la plus récente), très peu se sont intéressées aux raisons de non-consommation de tel ou tel type d'aliment, et notamment à l'évolution de ces raisons de non-consommation au cours de l'avancée en âge. Matériel et méthodes : 32 696 volontaires enrôlés dans la cohorte française NutriNet-Santé (20-80 ans ; 76% de femmes) ont évalué leur fréquence de consommation de 21 catégories d'aliments (eg, viande ; poisson & fruits de mer ; légumes crus…).
