Texto completoThe main challenges related to nutrition include ensuring an optimal diet, ensuring a good environmental impact of the food system, and ensuring food safety for consumers, including exposure to chemicals, especially since food is a major source of exposure to environmental pollutants for the general population. Consequently, this thesis embarks on a comprehensive analysis to address these challenges at the following levels: To meet the environmental and food safety challenges, through the development and implementation of a methodology to assess the impact of organic food consumption versus conventional food on consumer exposure to environmental pollutants in Europe, and to meet the challenge of ensuring an optimal diet for all, through the assessment of the nutritional quality of University Grenoble Alpes (UGA) students via a score based on the national nutrition program in France (PNNS) while studying the impact of food insecurity on adherence to national dietary recommendations. To achieve these objectives, a comprehensive database was first created to collect data from the literature on contamination levels in organic agriculture in Europe, as no exhaustive databases exist in the literature. Then, since the data from the database had limitations (quantitative and unit limitations) that prevented the direct calculation of exposure levels from the available data, an Excess Ratio (ER) approach was developed that first allowed the evaluation of the chemical content between different agricultural foods and served as the basis for the methodology to assess the impact of organic food consumption on the level of exposure to chemicals compared to conventional foods. Further, a population of UGA students was selected and assessed using a score developed based on the PNNS, and the association between food insecurity and adherence to the PNNS was examined. The dietary exposure profile of the students was assessed using the French Total Diet Study (EAT2) contamination database for selected substances and the developed methodology for assessing the impact of organic food consumption was applied to this population. As the students showed a level of concern for dimethoate, cadmium, lead, inorganic arsenic, nickel and dioxins, the impact of organic food consumption on the level of exposure to these substances was inconclusive. In terms of dietary quality, the overall compliance rate with the PNNS guidelines was 62%, with food insecure students showing lower compliance for fruits and vegetables (p = 0.004), alcohol (p = 0.005) and higher compliance for meat, poultry, and eggs (p = 0.021) and whole grains (p = 0.01). This thesis has provided a method that is universal and overcomes all the limitations of the currently available data, allowing the evaluation of the effect of organic food consumption. This thesis also serves as an illustrative example of a multifaceted research that addresses numerous challenges related to dietary practices

Texto completoLa nourriture issue de la chasse ou de la pêche comporte plusieurs nutriments essentiels à une bonne santé. Toutefois ces aliments peuvent aussi contenir des concentrations importantes en contaminants tel que le mercure et le plomb, qui posent un risque pour la santé. Pour guider les communautés qui basent leur alimentation sur la chasse ou la pêche, l’objectif global du projet est de développer une plateforme analytique permettant le suivi de la qualité alimentaire dans les environnements nordiques. Pour ce faire, une stratégie analytique de dissolution de la chair animale pouvant être employée à l’extérieur d’un laboratoire par des non scientifiques a été mise en place. Cette stratégie comporte l’échantillonnage, la mise en solution de la chair et la séparation des analytes pour effectuer leur analyse ainsi que le changement de matrice, en plus de la détection et de la quantification des analytes par fluorimétrie. Toutefois, puisque les systèmes de détection visés pour la plateforme sont en développement, une méthode de quantification du plomb et du mercure par ICP-MS/MS a aussi été développée. Cette stratégie analytique a été élaborée pour l’analyse de l’omble chevalier, un poisson consommé à l’année dans certaines communautés nordiques dans lequel les concentrations en contaminants sont très variables. Le processus analytique, de l’échantillonnage à l’obtention d’une solution mono élémentaire en passant par l’analyse ICP-MS/MS et la dissolution de la chair d’omble chevalier, sera décrit dans ce mémoire.
Fish and game meat contain different essential nutriments for a good health. However, it can also contain contaminants, such as mercury and lead, that pose a health risk. To guide the communities that base their diet on hunting or fishing, the main objective of the project is to develop a portable analytical platform that allows the monitoring of contamination by heavy metals of country food on the field. To this end, an analytical strategy for the dissolution of food flesh that can be deployed outside of the laboratory and used by non-scientists has been established. This strategy includes sampling, flesh dissolution, analyte separation and matrix exchange for the analysis in addition to fluorimetric detection and quantitation of the analytes. Since the quantification system for this platform is still under development, we therefore developed an ICP-MS/MS method to quantify lead and mercury in our food extracts. This method was developed to analyze arctic char, a fish consumed all year long in some northern communities and in which the contamination level can vary significantly. The analytical process from sampling to monoelemental analysis by ICP-MS/MS will be discussed in this document.

Texto completoThe present study is the first in Lebanon to evaluate, by the market basket approach, the contamination of foods by radionuclides and heavy metals and the dietary exposure of the Lebanese population to the heavy metals Pb, Cd and Hg. An individual dietary survey has been realized on 444 adult individuals living in Beirut. Food consumption data were collected using a quantitative food frequency questionnaire. The market basket was identified by selecting those foods with a mean daily intake exceeding 1g/day. The contamination levels of the selected foods with heavy metals and radionuclides were assessed. The results show that the level of radioactivity of the analyzed food does not present any concern for public health. The average dietary exposure of the average individual to Pb, Cd, and Hg corresponds to 7,17 and 6 % of the respective PTWIs. This permits to conclude that, for the average individual, there is no risk of exceeding the PTWIs

Texto completoThe reduction of salt (NaCl) content in food has become a matter of public health. However, the multiple functions of salt in food make the reduction of its content difficult. The aim of this work was to demonstrate the applicability of NMR innovative techniques in order to characterise the mobility of sodium ions (distinction between ‘free’ and ‘bound’ sodium), to bring a better understanding of the role of salt in the organisation of the food matrix (in particular phosphorous molecules in dairy systems) and to study impact of salt on the mobility of aroma compounds. In a first step, the 23Na NMR study of iota-carrageenan gels validated the quantification of total sodium (Single-Quantum, SQ experiment) and also demonstrated the involvement of ‘bound’ sodium ions in the gelation process of this polysaccharide (Double-Quantum Filtered, DQF experiment). The diffusion of aroma compounds in these systems was measured by 1H DOSY NMR, but no specific impact of salt was evidenced. The second step was dedicated to study dairy systems and semi-hard cheeses by 23Na NMR and solid-state 31P NMR using the magic angle spinning (MAS) technique. We demonstrated the feasibility of 23Na NMR methods for the quantification of total sodium and the characterisation of Na motional state (presence of ‘bound’ ions) in these systems. 31P MAS NMR (simple pulse excitation, SPE and cross-polarisation, CP) enabled the identification of different phosphorous compounds (inorganic phosphate, colloidal calcium phosphate, phosphoserins), the determination of their proportions and also permitted to determine the involvement of these phosphorous compounds in the protein network of coagulated systems. With these results, we achieved to identify the parameters of composition (or processing) influencing the dynamics of sodium ions in real cheeses. We also determined the distribution of phosphorous compounds, in particular inorganic phosphate, in these cheeses. This work demonstrates that these 23Na and 31P NMR innovative techniques are perfectly applicable to real food and can help to adjust the manufacturing process of cheeses in order to optimise their sensory and functional properties
