Full textCardiovascular disease remains one of the leading causes of death worldwide and hypertension is a major risk factor. Healthy eating plays a key role in blood pressure (BP) management. Data from observational studies suggest that consumption of dairy products, particularly those low in fat, is associated with lower BP and lower risk of developing hypertension. However, the results of clinical studies suggest a neutral effect of dairyproductconsumption on office BP. The controlled feeding study conducted as part of this memoiraimed to evaluate the effect of milk and cheese consumption on daytime ambulatory BP and other cardiometabolic risk factors. In a cross-over design, 55 participants were randomly assigned to a sequence of 3 experimental isoenergetic diets of 6 weeks each : 1) a control dairy-freediet; 2) a diet comprising 3 portions of 1% low-fat milk; and 3) a diet comprising 1 portion of cheddar cheese (31% fat) naturally enriched in -aminobutyric acid. Both ambulatory and clinical BP values were similar after each diet. In subjects with baseline ambulatory diastolic BP below the median, the milk diet significantly decreased the daytime ambulatory diastolic BP by 2 mmHg compared with the control diet. These results suggest that short-term milk and cheese consumption has an overall neutral effect on BP.

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 textChanges in demand are of public interest because of their effect on consumer health and the profitability of the industry. While the Canadian population ages, we observe a consistent downward trend in per capita milk consumption. This study investigates differences in the behav-iour of different profiles of Canadian households in terms of their purchases of dairy products. A two–stage econometric procedure was implemented on subsamples of a dataset pooling three food expenditure surveys. In the first stage, the probability of purchase is estimated to account for the relatively high frequency of zero purchases for some of the ten goods. In the second stage, a demand system allowing for quadratic expenditure effects is estimated. The findings indicate that demand elasticities tend to be higher for households headed by a person between 35 and 64 years old and when household size increases. Relative to other goods, low-fat milk has a higher probability of purchase and its demand is price and expenditure elastic. Generally, price and income elasticity patterns across goods are quite robust across household profiles differing in terms of the age of the head, size, and income.

Full textThe research in cane sugar by-products (molasses, syrup,juices) of food supplements with potential antioxidant properties was performed in order to valorize them. The nutraceutical concept, plausible mechanisms of oxidation, action means of antioxidant compounds and their different classes were presented before an overview of sugar products from Reunion Island. Quantification of phenolic compounds showed a progressive increase of the phenolic content in the by-products during the sugar fabrication process. In addition, many phenolic and aromatic compounds were identified in seven brown sugars (Reunion, Mauritius, France). Results of antioxidant assays on the sugar products established the increase of the activity during the sugar process. In addition, the seven cane brown sugars exhibited a moderate free radical scavenging capacity. Statistical data analyses performed on these sugar products pointed out the correlation between the increase of the phenolic content and the concomitant increase of the free radical scavenging activity. Statistical data analyses on the brown sugars showed that, besides their specificity (colour, aroma. . . . ), their origin is also a contributive factor to their aromatic composition, as well as the nature of the raw material (sugar cane) and the sugar fabrication technique (specificity of the factories). The results ascertained the possible valorization of sugar cane by-products as aromatic and colouring ingredient in new formulas (butter cakes, sweet buns, vanilla ice creams), therefore demonstrating the attractive properties (aromatic, gustative, functional) of the molasses. The achievement of this work was performed by mean of the following analytical techniques: measurement of polyphenols according to the Folin-Ciocalteu method, liquid and gas chromatography coupled with mass spectrometry, microplate reader with an ultraviolet spectrophotometry detector. Désoxyribose, ABTS, DPPH, β-carotène antioxidant and free radical scavenging assays were also performed. For the statistical analyses, experimental data was processed with PCA and FDA

Full textEco-efficiency is a concept specifically designed for the business world and which links theenvironmental and economic performances of a product or service. Since 2012, eco-efficiency is subject to a standardised assessment (ISO 14045) which imposes life cycle analysis to conduct the assessment of the potential environmental impacts. Eco-efficiency assessment thus offers the business world the opportunity to make decisions not only based on economical criteria but also factoring in the potential environmental impacts. Among the countless industrial activities likely to benefit from the eco-efficiency concept is dairy processing. Indeed, this sector of the agri-food industry surely enables valorisation of dairy raw material but it concomitantly exploits a significant part of the natural resources. The first objective of this thesis was to conduct a state of play on the development and implementation of the ecoefficiency concept in the dairy processing field. A first study enabled to look at the dairy processing activity from a life-cycle perspective, and to investigate the successive developments of the eco-efficiency concept in this field. In particular, the study showed that process simulation presented a sound interest in overcoming the difficulties associated with eco-efficiency assessment according to the ISO 14045 standard: the need for a complete inventory of material and energy flows, and for a certain expertise in life cycle analysis. Therefore, the second objective of this thesis was to develop a process simulation tool enabling the ecoefficiency assessment of the dairy processes. A second study thus led to the development of a software prototype allowing for eco-efficiency assessment of dairy products. This prototype relies on a process simulator specifically designed for dairy processes and which includes datasets of potential environmental impacts. These features allow for both the generation of detailed inventories of material and energy flows and potential environmental impact assessments, thereby overcoming the challenges identified in the first study. The developed prototype not only allows for eco-efficiency assessments of the modelled processes but also enables identification of the improvement opportunities, comparison of multiple scenarios of raw milk valuation, and assessment of the economic viability of the modelled scenarios. This tool was used in a third and last study in order to assess the contribution of pressure driven filtration operations to the overall eco-efficiency of dairy processes. These operations are omnipresent in the dairy processing activity and hold a potential for eco-efficiency improvement which has not been yet demonstrated. Three scenarios of Cheddar cheese production were compared in this study: two integrating pressure driven filtration processes at the cheese milk standardisation stage, and one that did not include such operations. Results revealed that although introducing pressure driven filtration processes at the cheese milk standardisation stage can significantly improve the cheese yields, it does not allow for an improvement of the eco-efficiency of the cheese production process. Analysis of the results showed that t he potentials for eco-efficiency improvements in dairy processing through the introduction of pressure driven filtration operations could probably be achieved by incorporating them in the by-product valuation processes. The research work conducted within the framework of this thesis fulfilled all the different objectives set and therefore should help make eco-efficiency assessment more accessible to all the decision-makers related in one way or another to the dairy processing industry.

Full textSome epidemiological studies suggest that genetic susceptibility modulates chlorination by-products (CBPs) effects on fetal growth. In a sample of 1432 mother-child pairs came from a population-based case-control study conducted in Quebec City area (Canada), we assessed the association between single nucleotide polymorphisms (SNPs) in CYP1A2, CYP2A6, CYP2D6 and CYP17A1 mother or foetus genes on intra-uterine growth restriction (IUGR) defined as small for gestational age (SGA 10th percentile). Further, we evaluated the interaction between maternal exposure to trihalomethanes (THMs) or haloacetic acids (HAAs) during the third trimester and SNPs in CYP1A2, CYP2A6, CYP2D6 and CYP17A1 mother or foetus genes. DNA was extracted from blood or saliva cells. Tag SNPs were selected by Tagger tool and the Sequenom’s MassARRAY system was used for SNPs genotyping. Analysis were performed by unconditional logistic regression with control of known risk factors of IUGR. Positive interactions were found between exposure to total trihalomethanes (TTHMs) and five regulated HAAs species and neonate carrying CYP17A1 rs4919687 A or rs743572 G alleles on SGA, whereas negative interactions were found between TTHMs exposure and mother carrying CYP17A1 rs4919687 A or rs743572 G alleles. However, after correction for multiple testing, reported interactions became non statistically significant. There is some evidence, albeit weak, of a potential modification of effect of the association between CBPs exposure and SGA by SNPs in CYP17A1 gene. Further larger-scale studies are needed to validate these observations.
