    Comparaison de l'impact des acides gras trans laitiers et industriels sur l'homéostasie du cholestérol chez l'humain
    (2010) Labonté, Marie-Ève; Lamarche, Benoît; Couture, Patrick
    Notre groupe de recherche a récemment démontré que des apports très élevés en acides gras trans naturels (AGTn) et industriels (AGTi) avaient des effets comparables sur les lipides et lipoprotéines plasmatiques. L'impact des différents AGT sur les processus impliqués dans l'homéostasie du cholestérol demeure toutefois inconnu et il nous est apparu important d'investiguer dans cette voie. Ce mémoire présente les résultats d'une étude dont l'objectif était de comparer l'impact des AGTi et des AGTn sur les marqueurs de la synthèse endogène et de l'absorption intestinale du cholestérol. Les résultats démontrent que le niveau d'absorption du cholestérol est modifié de façon plus importante suite à la consommation d'AGTn que d'AGTi, mais cette différence ne se reflète pas dans les concentrations de LDL-C entre les deux sources d'AGT. Il semble également que la consommation d'AGT n'affecte pas la synthèse endogène de cholestérol, peu importe leur origine.

    The influence of information about nutritional quality, environmental impact and eco-efficiency of menu items on consumer perceptions and behaviors
    (Elsevier, 2022-07-11) Plamondon, Gabrielle; Labonté, Marie-Ève; Pomerleau, Sonia; Vézina, Stéphanie; Mikhaylin, Sergey; Laberee, Laurence; Provencher, Véronique
    While food and dietary patterns are major determinants of a population’s health, our daily food choices also put pressure on the environment. In that context, providing graphical and comprehensive information is a widely used and potentially promising communication tool to promote healthier and more environmentally sustainable choices when eating out-of-home. Hence, the purpose of this study was to assess the influence of information about environmental impact and nutritional quality of meal options on consumers’ food choices, consumption and perceptions. A total of 80 men and 80 women were recruited, consisting of students and employees of Université Laval (Quebec City, Canada). Participants were randomly assigned to one of four experimental conditions, with menu information displaying: 1) greenhouse gas emissions scores, 2) nutritional quality scores, 3) eco-efficiency scores or 4) no information (control). Participants had to choose between two meals (i.e., beef burritos or chicken meal) both showing one of the above-mentioned conditions and then consume the chosen meal. Results indicated that nutritional and environmental information had an impact on meal choice. More specifically, participants exposed to such information tended to choose more frequently the meal with the most favorable score for the related condition (p-values < 0.05). However, no impact was observed on the amount of food consumed (p-values > 0.05). These findings suggest that communicating information about environmental impact and nutritional quality of menu items to consumers within institutional settings could be relevant to tackle more sustainable food choices.

    Alimentation et inflammation : considérations épidémiologiques, cliniques et métaboliques
    (2015) Labonté, Marie-Ève; Lamarche, Benoît; Couture, Patrick
    L’inflammation systémique et chronique dite « de faible intensité » est un élément clé du développement et de la progression de plusieurs désordres métaboliques tels que l’athérosclérose, le diabète de type 2 et les maladies cardiovasculaires. De plus en plus d’évidences suggèrent que l’alimentation jouerait un rôle de premier plan dans la modulation du profil inflammatoire, mais plusieurs questions demeurent non résolues à ce jour. Ainsi, l’objectif global du présent projet de doctorat était d’étudier l’impact de l’alimentation sur l’inflammation et ses mécanismes sous-jacents en utilisant trois approches expérimentales, soit 1) une approche épidémiologique, 2) une approche clinique et 3) une approche métabolique. L’alimentation a elle-même été étudiée sous différents angles incluant de simples nutriments (acides gras, dont les oméga-3), des aliments (produits laitiers) et des profils alimentaires reflétant l’alimentation dans sa globalité. En premier lieu, nous avons évalué les associations entre divers facteurs nutritionnels (oméga-3 et profils alimentaires) et le profil inflammatoire chez deux nations autochtones du Nord-du-Québec. Ces populations ont été choisies étant donné la forte et récente augmentation de la prévalence de plusieurs désordres métaboliques chez celles-ci parallèlement à un important phénomène de transition nutritionnelle. De façon globale, nos travaux démontrent que l’alimentation des Cris de la Baie-James et des Inuits du Nunavik semble exercer une influence non significative sur leur profil inflammatoire. En second lieu, nous avons réalisé une étude d’intervention nutritionnelle randomisée contrôlée portant sur l’impact de la consommation de produits laitiers sur l’inflammation ainsi qu’une revue systématique de la littérature sur le sujet. Il ressort de ces travaux que la consommation de produits laitiers dans le cadre d’une alimentation saine n’exerce aucun effet défavorable sur le profil inflammatoire. En troisième lieu, nous avons réalisé deux études d’intervention nutritionnelle randomisées contrôlées, conçues selon un devis en chassé-croisé, qui suggèrent que la consommation de divers acides gras, dont des acides gras oméga-3 d’origine marine, influence peu ou pas l’expression de gènes inflammatoires dans le sang de sujets avec obésité abdominale ou dans le duodénum d’hommes obèses et atteints du diabète de type 2. Bref, d’après l’ensemble des présents travaux, l’alimentation influencerait peu l’inflammation.

    Assessing nutritional value of ready-to-eat breakfast cereals in the province of Quebec (Canada) : a study from the Food Quality Observatory
    (CABI Pub. on behalf of the Nutrition Society, 2021-04-12) Perron, Julie; Pomerleau, Sonia; Gagnon, Pierre; Gilbert-Moreau, Joséane; Lemieux, Simone; Plante, Céline; Paquette, Marie-Claude; Labonté, Marie-Ève; Provencher, Véronique
    Objective: The Food Quality Observatory was created in the province of Quebec (Canada) in 2016. In this study, the Observatory aimed to generate a methodology to (1) test the use of sales data combined with nutrient values to characterise the nutritional composition of ready-to-eat (RTE) breakfast cereals offered and purchased in the province of Quebec (Canada) and (2) verify the extent to which a front-of-pack label based on the percentage of daily value (DV) for total sugar, as a strategy to improve the food supply, would be distributed in this food category. Design: Nutritional information were obtained by purchasing each RTE breakfast cereal available in the Greater Montreal area. Cereals were then classified according to their processing type. Setting: The nutritional values of 331 RTE breakfast cereals available in Quebec were merged with sales data covering the period between May 2016 and May 2017. A total of 306 products were successfully cross-referenced. Results: Granola and sweetened cereals were the most available (36·6 % and 19·6 %, respectively) and purchased (19·8 % and 40·9 % of sales, respectively). When compared with other types of cereals, granola cereals had a higher energy, fat, saturated fat, protein content and a lower Na content. A larger proportion of chocolate (65 %) and sweetened cereals (49 %) were above 15 % of the DV for sugar. Conclusions: This study showed that the methodology developed generates important data to monitor nutritional quality of the food supply and ultimately contribute to improve the nutritional quality of processed foods.

    Nutritional value of child-targeted food products : results from the food quality observatory
    (Cambridge University Press, 2021-08-05) Gilbert-Moreau, Joséane; Perron, Julie; Gagnon, Pierre; Pomerleau, Sonia; Labonté, Marie-Ève; Provencher, Véronique
    Objective: To characterise the nutritional quality of food products targeted to children, we aimed: (1) to determine if the nutritional composition of child-targeted food products is different from those for the general population and (2) to verify differences in the nutrient content of child-targeted food products between three selected food categories. Design: The present study is part of the work conducted by the Food Quality Observatory, created in 2016 in the province of Quebec (Canada). Ready-to-eat (RTE) breakfast cereals (n 331), granola bars (n 310) and yoghurts and dairy desserts (n 380) were the food categories analysed. Setting: Nutritional values and all packaging information were obtained by purchasing every product available in supermarkets, grocery stores and specialty grocery stores. Free sugars were manually differentiated from total sugars for each product. Products were classified according to two targeted consumer groups: children or general population. Results: The nutrient profile of RTE breakfast cereals, granola bars and yoghurts and dairy desserts targeted to children differed from that of products intended at the general population. Child-targeted RTE breakfast cereals had the least favourable nutritional composition, with significantly higher content of carbohydrates, total sugars, free sugars and Na compared with breakfast cereals for the general population as well as child-targeted granola bars and yoghurts and dairy desserts. All child-targeted products analysed contained free sugars. Conclusions: The current study supports the relevance to further regulate marketing to children on food product packages to ensure that such marketing is not present on food products with poor nutritional quality.

    Intakes of total, free, and naturally occurring sugars in the french-speaking adult population of the province of Québec, Canada : the PREDISE study
    (MDPI Pub., 2019-09-30) Bergeron, Amélie; Bédard, Alexandra; Couillard, Charles; Brassard, Didier; Lamarche, Benoît; Laramée, Catherine; Lemieux, Simone; Vohl, Marie-Claude; Labonté, Marie-Ève; Robitaille, Julie; Desroches, Sophie; Provencher, Véronique
    The objective of this study was to characterize the intakes of different types of sugars in an age- and sex-representative sample of French-speaking adults from five regions of the Province of Québec, Canada, enrolled in the cross-sectional PREDISE (PRÉDicteurs Individuels, Sociaux et Environnementaux) study (n = 1147, 18–65 years old; 50.2% women). Because only total sugar content of foods and beverages is available in the Canadian Nutrient File (CNF) 2015, the initial step of this study was thus to build a database of free and naturally occurring sugars content of each food item and recipe included in the R24W, which is an automated, self-administered, web-based, 24-h dietary recall validated to estimate nutrient intakes in French-speaking adults of the Province of Québec. Total sugars were manually differentiated into free and naturally occurring sugars using a systematic algorithm based on previously published systematic algorithms. The World Health Organization (WHO)’s free sugar definition was used to differentiate total sugars into free and naturally occurring sugars. Dietary intake estimates were assessed using three 24-h dietary recalls completed with the R24W. Mean total, free, and naturally occurring sugar intakes were 116.4 g (19.3% of daily energy intake (%E)), 72.5 g (11.7%E), and 44.0 g (7.5%E), respectively. Over half (57.3%) of the overall sample did not meet the WHO’s recommendation to consume less than 10%E from free sugars. Women had a higher %E from naturally occurring sugars than men and being younger was associated with a greater %E from free sugars. Sugar intakes among French-speaking adults from the Province of Québec were mainly in the form of free sugars, with the majority of the population exceeding the WHO recommendation regarding free sugar intake. This suggests that public health efforts towards reducing free sugar intake in this population are relevant and necessary, considering that overconsumption of free sugars negatively influences health outcomes.

    Nutritional content of sliced bread available in Quebec, Canada : focus on sodium and fibre content
    (MDPI, 2021-11-23) Perron, Julie; Plante, Céline; Guével, Marc-Henri; Gagnon, Pierre.; Pomerleau, Sonia; Le Bouthillier, Marie; Labonté, Marie-Ève; Provencher, Véronique
    Bread is a highly consumed food and an important source of nutrients in the diet of Canadians, underlining the need to improve its nutritional quality. The Food Quality Observatory (Observatory) aimed to evaluate the nutritional value of the sliced bread products available in Quebec (Canada), according to their grain type and main flour. Analyses included comparing the bread’s sodium content to Health Canada’s daily values (DV) and sodium voluntary targets, comparing the bread’s fibre content thresholds with the source of fibre mentioned, and assessing whether the main flour was associated with the nutrient content. The nutritional values of 294 sliced breads available in Quebec were merged with sales data (from October 2016 to October 2017), with 262 products successfully cross-referenced. The results showed that 64% of the breads purchased were ‘low’ in fibre (i.e., below 2 g per two slices), while 47% were ‘high’ in sodium (i.e., above 15% DV per two slices). Attention should be paid to 100% refined grain bread and to bread with refined flour as the main flour, since they are great sellers, while showing a less favourable nutrient content. This study shows that there is room for improvement in the nutritional content of Quebec’s bread offer, particularly regarding sodium and fibre content.

    A health at every size intervention improves intuitive eating and diet quality in Canadian women
    (Nutrition Publications, 2016-06-18) Carbonneau, Élise; Turcotte, Mylène; Lemieux, Simone; Mongeau, Lyne; Labonté, Marie-Ève; Paquette, Marie-Claude; Bégin, Catherine; Provencher, Véronique
    Background & aims: Health at Every Size® (HAES®) interventions focus on healthy lifestyle by promoting behavioral changes related to diet and physical activity while emphasizing self-acceptance and well-being through an empowerment and intuitive approach. The purpose of this study was to investigate the effects of a HAES® program on intuitive eating and diet quality in women. Methods: The HAES® intervention, offered by professionals from Health and Social Services Centers in Quebec (Canada), was composed of thirteen 3-h weekly meetings and a 6-h intensive day. For this study, 216 women (1.9% normal-weight, 21.1% overweight, 77.0% obese) who took part to the HAES program were compared to 110 women (3.9% normal-weight, 23.3% overweight, 72.8% obese) from a control group (waiting list). Intuitive eating was assessed using the Intuitive Eating Scale and diet quality was evaluated through the calculation of the Healthy Eating Index (HEI) from a validated web-based self-administrated food frequency questionnaire. Measurements were performed at baseline, post-intervention, and at one-year follow-up. Results: Women who participated in the HAES® program significantly increased their intuitive eating score compared to women in the control group at post-intervention and at follow-up (group by time interaction, p = 0.0002). A significant improvement in diet quality was also observed in the HAES® group in comparison with the control group at post-intervention (group by time interaction, p = 0.0139). The intuitive eating score and the HEI score were positively associated in the HAES® group at post-intervention (r = 0.20, p = 0.0237) and one-year follow-up (r = 0.22, p = 0.0359), but no such associations were noted in the control group (post-intervention, r = 0.04, p = 0.70; one-year follow-up, r = -0.15, p = 0.30). Conclusions: The HAES® program seems effective in improving intuitive eating and also favours improvements in diet quality. However, the association between intuitive eating and diet quality remains unclear, being positive and significant only after the HAES® intervention.
