Pouille, Céline. "Effets de la chicorée sur la santé animale". Electronic Thesis or Diss., Université de Lille (2022-....), 2022. http://www.theses.fr/2022ULILR076.
This project is part of a broad issue concerning the characterization of the health and nutrition potential of agri-food products derived from the natural biodiversity of chicory as well as its improved varieties. This issue aims to promote conventional products and especially those with functional food value, which therefore provide, beyond basic nutritional functions, physiological benefits and reduce the risk of chronic diseases.The objective of this thesis work was to test different products from industrial chicory (Cichorium intybus var. sativum), in particular flours produced from the roots, as well as different classes of molecules that enter the composition of the plant, to analyze their effects on animal and human health. This project included three stages of development: i) the characterization of the functional potential of food products (chicory flours and inulin) through nutrigenomic, physiological and metagenomic analyses in mice; ii) an in vivo and in vitro identification of the different classes of molecules responsible for the health effects observed (fructose, chlorogenic acids and sesquiterpene lactones), and iii) the evaluation of the impact of the in vitro simulated gastrointestinal digestion on the functional status of the flours and their compounds. The results obtained highlighted the antitumoral, anti-inflammatory, antimicrobial, antioxidant, on mice gut microbiota and the potential regulatory activity of energy homeostasis, of chicory flour and its bioactive compounds (Pouille et al., 2020; Pouille et al., 2022)

The increase of food safety preoccupations resulted in national decisions, especially with the creation of the French national food safety agency (afssa). Strict rules have also been established to fight against bse and to prevent consumption of contaminated products. As far as Europe is concerned, the creation of a common food authority agency makes mutual consent. But with the increase of international food trade, french and european levels are not the only ones concerned by sanitary safety. In order to avoid European union to face a dilemma between its rules in food safety and international trade liberty, Europe has to persuade the word trade organisation (WTO) to take into account its sanitary preoccupations
Dos, Santos Dias Ana Camila. "Champignons marins : lipidomique et lipides d'intérêt en santé et nutrition". Thesis, Nantes, 2017. http://www.theses.fr/2017NANT1010.
Marine fungi, despite their chemical diversity due to their constant adaptations, remain poorly investigated for their lipid diversity and therefore represent a potential source of lipids of interest in health and nutrition. In this context, after a screening of more than thirty strains of the MMS lab marine fungal collection, Clonostachys rosea MMS1090 and Acremonium sp. MMS540 were selected based on their lipid production, their fatty acid composition and their lipid profiling using lipidomic approach but also for the potential bioactivities of their lipid fractions. For both studied strains, a more comprehensive study using OSMAC approach (One Strain Many Compounds) was then performed in order to observe lipid profiling differences in terms of lipid diversity and production and to assess their potential to produce bioactive compounds. Methodology used, crossing lipidomic approaches, dereplication as well as conventional lipid purification techniques have been applied and permitted for C. rosea MMS1090 to isolate, identify and evaluate the biological potential of the conjugated fatty acid 4-Me- 6,8-16: 2, a glycosphingolipid and a sterol, the eburicol. These molecules exhibited bioactivities against cancer cells lines, in particular against MCF-7 breast cancer cell line, as well as Gram-positive and negative bacterial strains. In the same way, for Acremonium sp. MMS 540 it was also demonstrated the presence of bioactive glycolipid fractions. These first reports show the importance of further research in this area for the investigation of bioactive lipids
Chaltiel, Dan. "Développement et validation du score d’adhérence aux recommandations nutritionnelles françaises de 2017 et associations avec la santé". Thesis, Paris 13, 2019. http://www.theses.fr/2019PA131074.
This thesis presents the development and scientific validation of the PNNS-GS2, the dietary quality score based on the 2017 update of the French recommendations, as well as its association with overweight and obesity, mortality, cardiovascular diseases and cancers, pathologies frequently linked to diet.The analyses are based on data from participants from the NutriNet-Santé cohort, including validated 24-hour dietary records, numerous socio-demographic and anthropometric variables, and clinical-biological indicators.The associations observed between PNNS-GS2 and the socio-demographic, nutritional and clinical-biological factors studied are consistent with the literature and attest to its validity. Its significant association with a reduction in the risk of overweight/obesity, non-accidental mortality, cardiovascular disease and cancer contributes to reinforcing the relevance of the new nutritional recommendations.These results will promote the dissemination and scientific acceptance of these recommendations, and provide an indicator for further study

L’objectif général de la thèse est d’identifier des moyens novateurs afin de promouvoir la saine alimentation, soit la consommation de fruits et légumes, chez des femmes à risque de développer du diabète gestationnel. L’Intervention Mapping a servi de cadre pour planifier les étapes nécessaires au développement de l’intervention. Pour atteindre l’objectif de la thèse, quatre projets de recherche distincts, mais complémentaires ont été réalisés. Le premier projet de recherche impliquait d’effectuer une revue systématique sur la validation des mesures auto-déclarées de l’alimentation durant la grossesse. L’objectif était de recenser les méthodes utilisées pour mesurer l’alimentation durant la grossesse et de vérifier leurs qualités psychométriques pour identifier les outils à privilégier pour évaluer l’alimentation des femmes enceintes. L’objectif du deuxième projet de recherche était de valider un court questionnaire sur la consommation de fruits et légumes chez des femmes enceintes. Le troisième projet était une recherche formative dont l’objectif était de développer le contenu d’un questionnaire utilisant l’activation des intentions pour favoriser la consommation de fruits et légumes chez des femmes à risque de développer du diabète gestationnel. L’objectif du quatrième projet de recherche était d’évaluer l’efficacité d’une intervention de type activation des intentions comparativement à un groupe contrôle utilisant l’effet question-comportement pour promouvoir la consommation de fruits et légumes chez des femmes en âge de procréer (18 à 44 ans) à risque de développer du diabète gestationnel. Il s’est avéré que l’activation des intentions et l’effet question-comportement sont des techniques efficaces pour augmenter la consommation de légumes chez des femmes en âge de procréer à risque de développer du diabète gestationnel. Ce résultat suggère que ces deux techniques peuvent être utilisées pour favoriser une alimentation saine avant le début de la grossesse afin de diminuer le risque de développer du diabète gestationnel ou du diabète de type 2 et ainsi assurer la santé de la femme et celle de son enfant. Bref, les quatre projets de recherche de la thèse ont permis de développer une intervention qui utilisait un outil validé pour mesurer la consommation de fruits et légumes, qui répondait aux besoins de la population cible et qui fut efficace pour promouvoir la saine alimentation chez des femmes à risque de développer du diabète gestationnel.
The general objective of this thesis is to identify innovative ways to promote healthy eating, that is fruit and vegetable consumption, among women at risk of developing gestational diabetes mellitus. Intervention Mapping was used to guide the development of the intervention. To achieve the thesis’ goal, four distinct, but complementary research projects were conducted. The first research project was a systematic review on the validation of self-reported measures of foods and nutrients in pregnancy. The objective of this review was to identify self-reported measures assessing diet during pregnancy and to critically appraise their psychometric qualities in order to identify which tools should preferably be used among pregnant women. The objective of the second research project was to validate a brief questionnaire on fruit and vegetable consumption among pregnant women. The third project was a formative research whose objective was to develop the content of a questionnaire using implementation intentions to encourage fruit and vegetable intake in women at risk of developing gestational diabetes mellitus. The objective of the fourth research project was to test the efficacy of an implementation intentions intervention compared to a control group based on the question-behavior effect to promote fruit and vegetable consumption among childbearing age (18 to 44 years) women at risk of developing gestational diabetes mellitus. Implementation intentions and the question-behavior effect were effective techniques to increase vegetable consumption among childbearing age women at risk of developing gestational diabetes mellitus. This result suggests that these two techniques can be used to promote healthy eating before the onset of pregnancy to lower risks of developing gestational diabetes mellitus or type 2 diabetes and thus favor the health of the woman and her child. In sum, the thesis’ four research projects allowed the development of an intervention which used a validated tool to measure fruit and vegetable intake, which addressed the target population’s needs and that was effective in promoting healthy eating among women at risk of developing gestational diabetes mellitus.
Tremblay, Bénédicte L. "Analyse intégrée des données omiques dans l'impact de l'alimentation sur la santé cardiométabolique". Doctoral thesis, Université Laval, 2021. http://hdl.handle.net/20.500.11794/69041.
After cancer, cardiovascular disease (CVD) is the second leading cause of death and one of the leading causes of hospitalization in Canada. CVD management is based on the assessment and treatment of several cardiometabolic risk factors, which include metabolic syndrome, physical activity, and diet. A healthy lifestyle, including a balanced diet, remains the key to prevent CVD. A diet rich in fruits and vegetables is inversely associated with CVD incidence. Biomarkers of exposure to diet are used to study the impact of dietary factors on the development of CVD. Plasma carotenoids, a biomarker of fruit and vegetable consumption, are associated with cardiometabolic health. Diet also influences a myriad of omics factors, thus modulating CVD risk. Omics sciences study the complex set of molecules that make up the body. Among these sciences, genomics, epigenomics, transcriptomics, and metabolomics consider the large-scale study of genes, DNA methylation, gene expression, and metabolites, respectively. Given that a single type of omics data usually does not capture the complexity of biological processes, an integrative approach combining multiple omics data proves ideal to elucidate the pathophysiology of diseases. Systems biology studies the complex interactions of different omics data among themselves and with the environment on a trait such as health. There are several methods for analyzing and integrating omics data. Quantitative genetics estimates the contributions of genetic and environmental effects to the variance of complex traits such as omics data. Weighted correlation network analysis allows the association of a large number of omics data with a trait such as risk factors for diseases. The general objective of this thesis is to study the impact of omics determinants in the link between diet and cardiometabolic health. The first specific objective, using a quantitative genetics approach, is to characterize the heritability of omics data and plasma carotenoids as well as to check if their link with cardiometabolic risk factors can be explained by genetic and environmental factors. The second specific objective, using a weighted correlation network approach, is to assess the role of individual and combined omics data in the relationship between plasma carotenoids and lipid profile. This project is based on the GENERATION observational study, which includes 48 healthy subjects from 16 families. All omics data studied showed familial resemblances due, to varying degrees, to genetic and common environmental effects. Genetics and environment are also involved in the link between DNA methylation and gene expression, as well as between metabolites, carotenoids, and cardiometabolic risk factors. Moreover, weighted correlation network analysis has provided insight into the interactive molecular system that links carotenoids, DNA methylation, gene expression, and lipid profile. In conclusion, the present study, using approaches from quantitative genetics and weighted correlation network analysis, brought to light the impact of some individual and combined omics data in the link between diet and cardiometabolic health
Srour, Bernard. "Transformation des aliments et risque de pathologies chroniques dans la cohorte NutriNet-Santé". Thesis, Paris 13, 2019. http://www.theses.fr/2019PA131016.
During the past decades, diets in many countries have shifted towards an important increase in the degree of food processing and formulation. Several characteristics of ultra-processed foods have led the scientific community to wonder about their potential impact on long-term human health. Ultra-processed foods have in average, a lower nutritional quality than unprocessed or minimally processed foods (higher content of saturated fat, added sugar and salt, along with a lower fiber and vitamin density). They often contain food additives, neoformed compounds created during processes, and are often packaged in materials in contact with food from which contaminants may migrate to the food matrix. We investigated within the prospective French cohort NutriNet-Santé, the associations between the consumption of ultra-processed food and risks of cancer, cardiovascular disease, type 2-diabetes, overweight, obesity, and weight trajectories. More than 100,000 adult participants were included. Dietary intakes were collected using repeated 24 hour dietary records, designed to register participants’ usual consumption of more than 3,500 food items. These foods were categorized using the NOVA classification according to their degree of processing. Participants were followed, and the occurrence of chronic diseases was ascertained using a multi-source strategy including a linkage to medico-administrative databases.The analyses highlighted robust significant associations between the consumption of ultra-processed foods, and increased risks of overall and breast cancers, cardiovascular, cerebrovascular, and coronary heart diseases, type 2-diabetes, overweight, obesity and weight gain. These analyses accounted for a large number of lifestyle, socio-demographic, anthropometric, medical, behavioral, and nutritional factors. The associations remained significant throughout all the sensitivity and stratified analyses. Beyond nutritional aspects, various factors in processing and reformulation might play a role in these associations, and further studies are needed to better understand their relative contributions and to establish a causal link. Meanwhile, public health authorities in several countries have recently started to promote unprocessed or minimally processed foods and to recommend limiting the consumption of ultra-processed foods
Pichon, Paul-Emmanuel. "Perception et réduction du risque lors de l'achat de produits alimentaires en grande distribution : facteurs d'influence et rôle de la confiance". Toulouse 1, 2006. http://publications.ut-capitole.fr/686/.
For about twenty years now, food-related crisis have becoming recurrent, and the list of alerts and threats keeps on growing. Recent crisis and the spreading shadow of food fears have both deeply questioned the trust relation between consumers and various direct players of the food chain (i. E. Farmers, producers, food industry executives, whole salers and retail), but also indirect ones (government, consumers'associations, media). Even though the concept of risk is portrayed in various aspects in academic literacy, it appears that physical risk is predominant whilst consuming food. This thesis emphasizes particularly on physical risk, on the long and short term. This time differentiation illustrates well the whole complexity of food risk. Based on a survey of 400- over purchasers of beef meat in hypermarkets, this research permits a better understanding of the consumer-eater behavioral specificities in his/her perception, as well as his/her strategies at the purchasing stage. This thesis identifies notably certain individual factors (i. E. Anxiety, sensitivity to food crisis, self confidence) in the perception of food risk, in the long ans short run. This thesis demonstrates as well the usefulness of food risk reductors, those generated by the food sector players, as well the role played by trust in the risk- reduction phase
Jones, Cindy. "Le développement du soutien social par les groupes de cuisine collective comme stratégie de promotion de la santé mentale". Master's thesis, Université Laval, 2019. http://hdl.handle.net/20.500.11794/34972.
Since the last decades, collective kitchens are a phenomenon that has developed rapidly in the province of Quebec. They are a response to the limitations of traditional food aid services, more « assistance-based approaches », by working on developing the potential of individuals and communities in food security. Collective kitchen have become a way of intervention that goes well beyond food support. We hypothesized that collective kitchens have the potential to promote positive mental health, the psychological well-being of individuals through improved social support and at the same time improved health protective factors. This qualitative research focuses on the perception of participants in collective kitchens groups on the psychosocial effects of kitchens. This research also studies the factors facilitating the emergence of support dynamics in the collective kitchen groups. Two methods of data collection were used: the semi-structured interview with members of collective kitchens and the observation of five cooking groups. The results show that for a large majority of members the motivation to engage is a desire to reduce the social isolation in which they live. Overall, the collective kitchens favor social interaction, experience sharing, mutual aid, autonomy and self-esteem. However, the emergence of support dynamics is influenced by several factors: the role of group facilitator, the group climate, the sense of belonging and the group structure. The results show that by developing participants' personal and social skills, kitchen groups are an effective measure in promoting mental health. We suggest a variety of practice interventions to promote positive outcomes for participants. One of the suggestions is that social interactions between members should be strongly encouraged and promoted through moments of sharing in kitchens.

Olive oil polyphenols are well-known to lower cardiovascular mortality and type 2 diabetes incidence associated to the Mediterranean diet. However, the high metabolization rate of hydroxytyrosol, the main phenolic compound of olive oil, into glucuronides, questions its real biological effect. The first objective of this thesis was to evidence the importance of glucuronides of Hydroxytyrosol in the enhancement of vascular function through antioxidative properties. It was found that, unlike to hydroxytyrosol that can be directly transported with bilitranslocase glucuronides have to be deconjugated by β-glucuronidase to exert their biological activity. A second objective was to evidence the effects of Hydroxytyrosol and glucuronides on vascular function in diet-induced metabolic syndrome rats. Neither hydroxytyrosol nor glucuronides modulated vascular function in this pathological context. A third objective was to show the effect of a chronic Hydroxytyrosol supplementation in refined olive oil on cardiovascular risk factors in a mice model of Metabolic Syndrome. Hydroxytyrosol supplementation was able to reduce weight gain, white adipose tissues mass and to lower blood pressure. These hypotensive effects seem to be due in smooth muscle cells function. In conclusion, our works highlight the importance of Hydroxytyrosol and its glucuronoconjugated metabolites, both contributing to the reduction of the incidence of cardiovascular risk factors associated to type 2 diabetes and Metabolic syndrome

These last decades, Solieria chordalis (Rhodophyta, Gigartinales), a red and proliferative macroalga appears every year in south of Brittany on the peninsula of Rhuys. It is a question of removing more than 2 000 tons of red seaweeds, mainly composed of S. chordalis. These proliferations represent a true ecological problem and an economic constraint for the affected communities. This project aims to study S. chordalis in order to find a way to add more value to this seaweed by proposing a rational and sustainable management as well as potential applications. From October 2013 to October 2015, S. chordalis was collected monthly. Results have shown seasonal variations of the biomass on the shores, in the macro- and microscopic morphologies, in the dry matter rate and in the biochemical composition. In relation with the seasonal environmental factors, it is now possible to estimate the quantity and the biochemical composition of the seaweed and to propose potential applications. With characteristics of high catalytic efficiency, specificity, the environmental-friendly process of Enzyme-Assisted Extraction was chosen to produce water- soluble extracts with antiviral, antibacterial and immunostimulant activities. The commercial protease Alcalase improved the extraction yield with a significant gain of 30 % of the water-soluble and free compounds compared to an extraction without the action of enzymes. Almost 60 % of the dry matter of algae was liquefied and water-solubilized after the optimization of extraction parameters. Water-soluble extracts produced after the action of enzymes have shown anti- herpetic activities (EC50 from 86.0 to 145.9 µg/mL) and no cytotoxicity was detected. The immunostimulant activity was evaluated by using the pathogenicity model Caenorhabditis elegans Pseudomonas aeruginosa. The life span of infected nematods by pathogen bacteria increased after the application of water-soluble extracts from S. chordalis. Some immune genes of C. elegans were stimulated (zk6.7, spp-1, f28d1.3 and f38a1.5). Produced extracts present antiviral and immunostimulant activities that allow to anticipate applications for diverse domains
Hunsmann, Moritz. "Depoliticising an epidemic : international AIDS control and the politics of health in Tanzania". Paris, EHESS, 2013. http://www.theses.fr/2013EHES0021.
AlDS-control strategies in sub-Saharan Africa involve crucial national political compromises. Yet, they are frequently formulated in heteronymous settings dominated by Western donor agencies. Drawing on a case study of Tanzania, a country whose response to the epidemic is 97% donor-funded, this thesis develops a political economy of international AIDS control. It explores some of the specifically political aspects of the struggle against HIV/AIDS in Tanzania by analysing the formulation of national 1-llV-prévention and treatment policies, and confronting these policies with a critical review of their biological and epidemiological foundations. The fieldwork combines a series of 92 in-depth interviews with key policymakers at the national level with the observation of AIDS-related decision processes in donor-government meetings. In this way, this \l1ésis analyses the unequal political attention given to different causal stories of the spread of HIV, and their impact on the use of evidence in the formulation of prevention policies. Moreover, it describes how AIDS policymakers adopt non-decision strategies when faced with the intricate trade-offs imposed by the inescapable prioritization of HIV-prevention and -treatment interventions in a context of insufficient resources. Finally, developing upon an analysis of the controversy among players about the effects of international AIDS control on the overall coherence of national health policies, the thesis explores the contradictions of a vertical AIDS response in a context of dysfunctional health systems and poor general population health. On this basis, it examines the possibilities to elaborate an emancipatory critique

Oxidative stress in intensive livestock farming can induce severe deleterious effects on animal health and performances, as well as their derived products. Among the antioxidant solutions developed to fight against this phenomenon, are feed additives, rich in plant secondary metabolites.The aim of this work was to elucidate the impact of a dietary supplementation consisting in a small dose of grape extract on the performances and metabolome of animals, raised in intensive conditions.The creation of a method of analysis of very small doses of the additive (5μg/g) in the complete feed constituted a first axis, in order to insure traceability of the product and resulted in a patent.Moreover, a trial consisting in the supplementation of rainbow trout with a small dose of the grape extract (60ppm) evidenced a modulation of the eggs’ metabolome and a significant improvement of the offspring’s growth (+5.2% weight at 8 weeks).Finally, the impact of the modulation of the phenolic profile of the additive, used in small dose in the complete feed (30ppm) of laying hens exposed to a dietary stress was studied. Results evidenced variations of the impact of the 3 grape extracts tested on zootechnical, biological and metabolomic parameters.This research allowed to collect necessary data for the registration of the studied grape extract as a zootechnical feed additive, within the European Union, to fight against oxidative stress

Citrus fruits, which are widely consumed worldwide, represent sources of carotenoids such as βCX, which contribute with flavonoids (HES) to the health effects of these fruits, particularly in the prevention of type 2 diabetes (T2D). T2D is a worldwide pathology that is growing exponentially. The general objective of this work is therefore to study the nutritional and health properties of clementine juice concentrates obtained by innovative membrane technology and specifically enriched in both βCX and HES but also in pectins. The digestive behaviour of these phytomicronutrients, guarantors of the nutritional quality of the concentrates, was first assessed by coupling the in vitro digestion model with the Caco-2 intestinal cells. For a better physiological vision of the mechanisms associated with the first stages of digestion, models of static and dynamic digestion are compared. The bioavailability and intestinal absorption of carotenoids are strongly influenced by the content and structure of pectins. In a second step, the biological activities (disglycemia, dislipidemia, inflammation) involved in the prevention of T2D are evaluated in vivo in rat after administration of the citrus concentrate. The study demonstrated that a citrus food specifically enriched in βCX and HES is effective in preventing metabolic syndrome/T2D, highlighting the possible role of βCX and its retinoid bioconversion. A complementary in vitro study on murine macrophages reveals synergistic anti-inflammatory effects of the two phytomicronutrients

Neurodegenerative diseases (NDD) mainly concern neuromuscular diseases, including amyotrophic lateral sclerosis (ALS), dementia, including Alzheimer's disease, Parkinson's disease, multiple sclerosis, Huntington's disease. Due to the multiplicity of factors inducing a weight loss, the NDD are at risk of malnutrition, which can alter the evolution of these diseases and the quality of life of patients. The purpose of this work was to assess the nutritional status and / or the effect of treatment of patients with ALS and cognitive disorders (dementia and / or mild cognitive impairment [MCI]) in France with a health network, but also in Central Africa. The health network Limousin Nutrition (LINUT) realizes assessments and nutritional interventions in ALS patients at home and in residents of nursing homes (NH). The first evaluation by the network of ALS patients found more swallowing disorders than specialized consultation (60.0% vs. 47.5%) and taste disorders (43.8%), not further described in ALS. Improvements of practices were proposed. The network assessed also residents in NH, with or without dementia, initially and after a 4 months follow-up. Malnutrition affected more often demented patients (56.1% vs. 46.4% p=0.004), and energy intakes of all residents (26.4 ± 8.8 kcal/kg/d) were below the recommendations. The network intervention improved the nutritional status of patients with dementia (+0.29 ± 0.07 point of MNA®/month, p=0.003) and energy intake of all residents at 4 months. Two studies named
