Full textEpidemiological data reported that an adequate dairy product consumption may lower the incidence of type 2 diabetes (T2D), a chronic disease which may concern 10.8 % of Canadians by 2020. Although the mechanisms underlying this association remain unclear, it has been suggested that dairy product intake may improve low-grade systemic inflammation, a key etiologic factor in the development of T2D. However, dairy products have mixed effects on inflammatory markers in clinical studies. The effect of dairy products could be mediated by the inflammatory status of the participants, as well as the nutrient composition of dairy products. Dairy products contain proteins, amino acids and fatty acids, specifically natural trans fatty acids, for which the effect on inflammation remains unclear. Furthermore, it has been demonstrated that dairy nutrients can regulate inflammatory gene expression. Nevertheless, a mechanistic approach is required to elucidate the role of dairy products on inflammation and the prevention of T2D. Accordingly, we tested the hypothesis that the effect of dairy products on inflammation was influenced by the inflammatory status of the individuals and the macronutrient composition of dairy products. Therefore, the main objective of this thesis was to evaluate the contribution of those two factors on inflammation. Firstly, dietary, anthropometric and biochemical data from two cohorts of individuals recruited in Quebec City were assessed. Results show that dairy product consumption is inversely correlated with glycaemia and blood pressure in healthy individuals. Dairy intake is also slightly correlated with plasma C-reactive protein (CRP) concentrations, without influencing other inflammatory markers (tumor necrosis factor alpha (TNF-α) and interleukin 6 (IL-6)). Moreover, concentrations of dairy trans fatty acids in plasma phospholipids are associated to high-fat dairy product consumption, as well as favorable adiponectin levels and blood pressure. Secondly, we developed cell models, with or without induction of inflammation with TNF-α, to identify bioactive dairy nutrients. Cells were incubated for 24 hours with individual or combinations of dairy trans fatty acids, proteins or amino acids. Dairy trans fatty acids and dairy protein compounds do not influence inflammatory gene expression in healthy cells. Oppositely, dairy trans fatty acids, whey proteins and their major amino acids (leucine, isoleucine and valine) decrease inflammatory gene expression in TNFα-stimulated endothelial cells. Dairy trans fatty acids also lower prostaglandin excretion; yet they increase F₂-isoprostane levels in cell supernatants. Moreover, dairy trans fatty acids are highly incorporated into cell membranes, which modifies fatty acid profiles and possibly impairs the function of membrane receptors. Finally, co-incubation of dairy trans fatty acids and dairy protein compounds have neither an additive nor a synergic effect on inflammatory gene expression and eicosanoid levels in endothelial cells. The present work suggests a beneficial impact of dairy trans fatty acids and whey proteins on inflammation. Further, the anti-inflammatory effect of these nutrients appears only in inflamed cells, which favors the hypothesis that dairy products may positively impact inflammation according to the inflammatory status of the individuals. The cellular approach is a useful tool to investigate the impact of the different sources of variability regarding inflammatory response to dairy products. Further investigations in vivo are required to validate the major sources of variability in animal models or in humans.

Full textOlive 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

Full textCitrus 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

Full textThis master’s thesis concerns type 2 diabetes self-management strategies developed by the women of Reunion Island. Our research was conducted in the French Overseas Department where 15 % of adults are affected by this disease. We were inspired by the model described by Kleinman et al. (1978) and Young (1982) on the three dimensions of the disease, namely disease / illness / sickness, further developed by Massé (1995), to understand how women managed to cope with diabetes in their social and family environment. Data for the analysis was collected using individual interviews as well as one focus group. The women who succeeded in managing their diabetes more efficiently are the ones who managed to create a sphere of negotiation between medical advice and their life context. We first describe the reality of women through their culture, roles and obligations. The medical recommendations are then presented which, considering the biological dimension of the disease (disease), are often disembodied from what women live. Finally, we see how using lay knowledge, which can be described as an interpretation of medical, alternative and popular discourses, as well as one’s own experiences, helped these women to successfully develop strategies to negotiate between their everyday lives and the constraints of the disease. Some facilitators of the negotiation process are also identified. Those people that have found the means to adapt to the disease could potentially be involved in the development of intervention processes based on lay knowledge which would be better adapted to the reality of diabetic people living in Reunion Island, where this disease is on the rise.
