Der volle Inhalt der QuelleCan the food system change ? As they formulate criticisms toward the regime which dominates food provision, alternative phenomena have, for over twenty years now, suggested that the sustainability, quality, and transparency of food provisioning could improve by shortening relations between producers and consumers. The discourses, practices, and innovations of such Alternative Food Networks (“AFN”) generate, through multiple oppositions to the industrial food provision regime, frictions among the latter. Having witnessed spectacular developments these past few years bringing quite a heterogeneous variety of AFN to the fore, this regime has begun to undergo a series of internal questionings and takes on local food. The theorization of these frictions can benefit advantageously from the Multi Level Perspective (“MLP”), a theoretical and methodological framework for research in transitions studies, which enables an evolutionist read on sociotechnical regimes, in particular regarding their relations with alternative, innovative niches. With the help of robust sociohistoric analysis and fieldwork, it then becomes possible to reflect upon the modalities which could bring about a food provision regime transition through the shortening of links between producers and eaters.The thesis thus proposes two analytical foci: the food provision regime; and Alternative Food Networks. It calls upon a composite methodology to address data which are very heterogeneous in nature and stem from distributed empirical fields: discourse analysis through lexicometrics, the analysis of digital traces, the study of institutional displays, in-depth interviews, and ethnography-inspired observations. Aiming at meso-level theorizations, the thesis targets – as they question themselves on local food issues – key actors representative of several competencies, which fulfill major functions in the provision regime: retail; fruit and vegetable supply; institutional food fairs. The alternative objects report, through their study, a multiplicity of forms of existence. Because these alternatives are partially intertwined with certain devices from the dominant regime, this leads the thesis toward the in-depth study of one of these AFN, which is very particular in that (i) its architecture stems from a hybrid between food alternatives and digital-material networks enabled through technological platforms, and (ii) the dataset which it offers is of unusually high standard.Through this distributed empirical approach, the thesis contributes to the characterization of a transition toward a digital-material provision regime based on prosumption through transparent customization. Dating the regime’s inflection point to the late 2000s, the conjunction of a crisis in the provision model with the explosion of digital flows as well as the continuous expansion of claims and practices in the realm of alternatives, appear to be able to quicken the pace of a transition pathway through a reconfiguration of the regime. The premise of this reconfiguration manifests itself through multiple evolutions in discourse which can be scrutinized within the regime, as well as the incorporation and the redisplay, in the realm of the regime, of alternative phenomena which participate increasingly in the characterization of new priorities which now redefine food specifications, provision practices, and provision flows. The accrued value of food products enriched with new alternative specifications which are conveyed through new virtual and material proximities thus intimate the regime to interrogate itself on the potential offered by the shortening of provision. Bridging three investigative fields (transitions; Alternative Food Networks; prosumption) which are, as of yet, relatively disconnected, the thesis thus opens research perspectives on the capacities through which such shortened markets may be able to capture the attention of food prosumers who likewise, are very much thriving

Der volle Inhalt der QuelleDifferent types of duodenal nutrients alter gastroduodenal mobility. On the contrary, few data are available on the gastroduodenal motor effects of acute diet changes or unbalanced diets, two situations generated by occidental type diets. We built two experimental animal models to study in one hand the effects of an acute diet change from an animal-based diet to a plant-based diet, and on the other hand the consequences of isocaloric unbalanced diets with fat or carbohydrates excess. Rapid diet changes reduce the sensitivity of duodenal vagal afferents when they are simulated by duodenal intralipid or differents neurotransmitters such as CCK or 5HT. This reduced sensitivity is causative for the reduced gastric emptying rate observed after rapid diet changes. Intrlipid duodenal administration in animals chronically feed with isocaloric high fat diet is unable to induce a reduction in gastric compliance, after antro-pyloro-duodenal motility pattern and ultimately lead to the suppression of the duodenal brake on gastric emptying. Some of these effects are also found with high carbohydrate diet. Finally, in the inteerdigestive state and without an additional intralipid administration the high fat diet but not the high carbohydrate one induces an alteration of the duration of the migrating motor complex. In conclusion, an overall desensitisation is observed, either at the level of the duodenal vagal afferent or at the level of the whole body, is respectively induced by rapid diet change and by high fat, and to a lower extend by high carbohydrate diets

Der volle Inhalt der QuelleThe work presented in this PhD dissertation deals with thermodynamic and kinetic studies of metal complexation by dietary polyphenols in order to gain insight into the effects of these molecules on the bioavailability of cations relevant to human health, copper(II), zinc(II), iron(III) and aluminium(III). A combination of potentiometry, spectrophotometry and electrospray mass spectrometry was used at equilibrium. A fast mixing spectrophotometric technique was employed in order to establish the uptake and release mechanisms of the metallic cations. In the first bibliographical part of this manuscript, we present the various effects of dietary polyphenols on human health and recall the physiological functions of the cations examined in this work. We then examined the chelating properties of quercetin, which is a very abundant flavonol in our diet, and of three related polyphenols, apigenin, galangin and rutin, with two divalent cations, copper(II) and zinc(II) and two trivalent cations, iron(III) and aluminium(III). Our results point out a high affinity of the studied polyphenols for the trivalent cations, whereas the affinity for the divalent cations under physiological conditions is much weaker. The uptake and release mechanisms of copper(II), zinc(II) and aluminium(III) by quercetin and of iron(III) by quercetin, rutin and apigenin was studied. The chelation of these four cations is fast and efficient as it follows a dissociative Eigen-Wilkins mechanism. Finally, we modelled the uptake of iron(III) by polyphenols under physiological conditions and suggest a mechanism for the exchange of iron(III) between nitrilotriacetic acid, used as a model tricarboxylic compound, and catechin, a catecholate type polyphenol very abundant in teas

Der volle Inhalt der QuelleFuture climate related risks depend on our ability to curb greenhouse gas (GHG) emissions, which require a profound food system change. Organic farming and dietary shifts towards more plant-based diets are often seen as promising ways to mitigate GHG emissions. They are both promoted by the European Union (EU), which aims for climate neutrality by 2050. However, the expansion of organic farming is controversial, as it could lead to land-use changes – and associated CO2 emissions – to compensate for lower productivity. Therefore, the EU’s goal of dedicating 25% of its agricultural land to organic farming by 2030 has been criticized, particularly because the globalization of agricultural trade could lead to emissions being shifted to other regions. Furthermore, the interactions between dietary changes and the development of organic farming have not been sufficiently explored. A reduction in livestock, driven by a lower demand for animal products, might relax agricultural land demand for producing feed and compensate for higher land requirements of organic systems. However, the reduced availability of manure could negatively affect nitrogen (N) inputs to organic crops and challenge organic systems productivity. This could undermine the GHG mitigation potential of both strategies, especially in the case of a drastic reduction in animal product consumption, as in vegan diets. Therefore, the aim of this thesis is to assess the combined effects of these two levers in Europe on land use and GHG emissions, considering the effects related to the N cycle. We first reviewed studies that explored the effects of organic farming expansion using a modeling approach. We showed that considering N availability feedback on crops yields exacerbates the anticipated drop in agricultural production. Next, we used the GlobAgri model, which computes cropland and permanent grassland requirements at the scale of large global regions in 2050, to simulate the adoption of vegan diets in Europe, with or without maintaining livestock production for export. Our results show that the impacts on croplands N balance depend on the relative adjustment of two compensatory factors: the decrease in manure availability, and the decrease in the land required for producing feed. Finally, we simulated scenarios combining dietary changes and widespread adoption of organic practices by coupling two models: i) GOANIM, which simulates N balances of organic croplands, yields, and animal densities, and ii) an adapted version of GlobAgri. We found that a higher share of organically managed croplands would lead to an increase in European cropland requirements, due to lower crop yields and changes in crop rotations. This increase would allow Europe to maintain its export shares, preventing emissions to increases in the rest of the world. In a scenario without dietary changes, 25% organic croplands would increase the domestic GHG balance by 10%. In scenarios combining more plant-based diets with more disruptive organic practices, emissions from land-use changes would be offset by reduced land requirements and emissions from agriculture, up to 50% organic croplands. Beyond that, the land demand to maintain export shares would be too high. Overall, our work contributes to include complex interactions between crops, livestock, N cycle, global trade, and GHG emissions in large-scale models. It provides suggestions for effectively combining the expansion of organic farming with dietary shifts towards more plant-based diets
