Full textLa incidencia durante los últimos años en las poblaciones europeas de la enfermedad cardiovascular y patologías relacionadas como la obesidad, sugiere una desviación de los "patrones alimentarios prudentes" a los denominados "patrones occidentales", caracterizados por elevadas ingesta de grasas, carne y cereales refinados. Este hecho plantea la necesidad de preservar y promover la dieta mediterránea tradicional en la población europea, sin excepción de los países mediterráneos que le han dado origen.
Por ello, en esta tesis se evaluó el estado nutricional, así como el grado de cumplimiento de los actuales objetivos nutricionales nacionales y europeos, y del patrón alimentario mediterráneo en la población catalana actual. Como biomarcadores biológicos específicos del perfil lípidico, se estudió la composición de ácidos grasos plasmáticos, totales y de fosfolípidos de una muestra representativa de la población catalana. La técnica analítica utilizada fue la cromatografía de gases rápida, campo en el que se pusieron a punto tres novedosos métodos análiticos.
Esta tesis permitió identificar los alimentos que contribuyen en mayor medida al porcentaje de energía procedente de los lípidos en la población catalana actual. El aceite destacó con un 7% de energía relativo a los lípidos totales, y el queso en cuanto a la grasa saturada, a diferencia de los productos lácteos, que eran los mayores contribuyentes de grasa saturada en la pasada década en esta población. La evaluación del índice de calidad de la dieta mediterránea mediante un enfoque metodológico a priori concluyó que un 64% de la población catalana se halla en el rango de cumplimiento de las características principales de la dieta mediterránea, presentando tan sólo un 5% de la población una baja adhesión a este patrón alimentario.
En cuanto al grado de cumplimiento con los objetivos nutricionales, conviene destacar el elevado porcentaje de cumplimiento en relación a las frutas y verduras, superior al 75%, y el bajo porcentaje en cuanto a hidratos de carbono, inferior al 3% en cuanto a las recomendaciones europeas de aportar un 55% de la energía diaria. También se concluyó que las mujeres presentaban mayor grado de cumplimiento en relación a los ácidos grasos monoinsaturados y poliinsaturados, atribuible a su mayor consumo de aceite de oliva y de pescado respectivamente. Según los resultados obtenidos, la ingesta media de pescado en la población catalana es del orden de 80 g/dia, siendo tan sólo un 25% debido a pescado azul, que es el más rico en ácidos grasos poliinsaturados de cadena larga. La relación entre el contenido plasmático de EPA y DHA y los factores de riesgo cardiovascular clásicos mostró una relación inversa significativa entre el EPA y los niveles de colesterol total, trigliceridos e insulina, pero ninguna relación con los niveles de DHA. Paralelamente se estudió el efecto de un consumo moderado de aceite de oliva, principal componente de la dieta mediterránea, en individuos de cinco poblaciones europeas con diferentes hábitos alimentarios, concluyéndose que 25 ml/día de aceite de oliva pueden ser una herramienta útil para disminuir la presión sistólica en hombres europeos.
The lipid composition of the human body reflects the endogenous lipid formation as well as the dietary lipid intake. An excess of energy, not only from lipids but also from the other macronutrients can lead to an increase in the cardiovascular disease risks.The increasing scientific evidence suggests that some dietary patterns can positively influence CVD risk factors. Among the healthy dietary patterns the Traditional Mediterranean Diet is highlighted. There is a need to maintain and promote this diet in the European population, without exception of the Mediterranean countries where it originated.
This thesis focused on the evaluation of the nutritional status, compliance with the current European and national nutritional objectives, and adherence to the Mediterranean Diet by the current Catalan population. As specific biomarkers of the lipid profile, the fatty acid profile in total and phospholipids was evaluated in plasma. The analytic technique in use was fast gas chromatography, having developed three new analytic methods in this research field. The thesis allowed the identification of those foods which contribute most to the lipid profile in the current Catalan diet. Oil was the major contributor with 7% of relative energy from total lipids. Cheese is the food that contributes to the current Catalan diet with a higher percentage of saturated fat energy. The evaluation of the Mediterranean Quality Dietary Index in the representative Catalan sample suggested an appropriate adherence of the Catalan population to the Mediterranean dietary pattern. Furthermore, the current Catalan population follows most of the Spanish and European nutritional objectives. An increase of the carbohydrate intake should be recommended due to the fact that less than 3% accomplish the European nutritional objectives for this macronutrient. Nevertheless, a high compliance of fruit and vegetable intake was highlighted. According to our results, blue fish intake was estimated in only one portion per week, implying a future need to promote an increase in its consumption. In addition, the multicentric randomized cross-over study in 5 European populations, concluded that a moderate olive oil administration of 25 ml/day could be a useful tool to reduce the blood pressure in healthy men from European populations.

Full textFat addition is a common practice in feed manufacturing in order to increase the energetic density of diets and provide essential nutrients to livestock animals. The availability of conventional energetic ingredients for broiler chicken diets may be compromised by a constant growing world-wide population and the current tendency to use vegetable oils for biodiesel production. In this context, soybean lecithin (L), as a co-product obtained during soybean oil (S) refining process, may represent an economical and alternative energy source due to its high content in phospholipids, triacylglycerols, free fatty acids (FFA), phosphorus, choline and antioxidant compounds. Therefore, the global aim of the present thesis was to investigate the potential use of L, as energy source for broiler chicken diets. Several trials were performed with the aim to evaluate the inclusion of L as energy source in broiler feeding and study its influence on performance, energy utilization, fatty acid (FA) digestibility and the FA profile of the abdominal fat pad. A basal diet was supplemented at 3% with either S or acid oil (A) and increasing amounts of L (crude and high in FFA for Chapter Three and Four, respectively) were included in replacement (1%, 2% and 3%). In relation to S replacement, despite no effects were observed on performance parameters, results from the digestibility balances indicated that S replacement by L, in starter broiler chickens, lowered FA digestibility and the apparent metabolizable energy content of the diets. However, in grower-finisher broiler chickens, partial replacements up to a 2%, did not modify performance, and the utilization of energy and total FA. Regarding the replacement of A by L, in starter and grower-finisher broiler chicken diets, it was observed that blending both co-products have resulted in improvements on energy and nutrient utilizations. Finally, the FA profile of the adipose tissue was a clear reflect of the FA composition of the added fats, and S replacement by L produced slight changes on the FA profile of the abdominal fat pad. The last experiment (Chapter Five) consisted in a field trial under experimental conditions with the main objective to study, in grower and finisher broiler chicken diets, different levels of L inclusion in replacement of S and its effects on growth performance. In addition, ileal absorption of FA, FA profile of the abdominal fat pad and gut health markers were assessed. Soybean oil total replacement by L (2% of inclusion), in diets that also contained palm and A (3.25% and 4.5% of total added fats for grower and finisher diets, respectively), did not modify performance parameters, total FA ileal digestibility and jejunal morphology. On the other hand, a reduction on the digestibility of the polyunsaturated FA and an increase on Lactobacillus spp. counts at the jejunum were linked to total replacement; however, with no significant consequences on growth efficiency. Slight modifications were observed on the saturation degree of the abdominal fat pad, associated to the FA profile of the different added fats. Taking all the results into account, it was evidenced that L is a suitable energetic ingredient for grower and finisher broiler chicken diets due to it was observed that S partial replacements up to a 2% by L do not alter growth performance and the utilization of energy and FA. Besides, the blending of L and A results an interesting option, for adult broiler diets, due the existence of positive interactions on energy and FA utilization.

Full textBreast cancer is the most common malignancy among women all over the World. Besides the genetic, epigenetic and hormonal factors, there is epidemiologic and experimental evidence that nutritional factors have a role in the aetiology and the development of this disease. The dietary lipids have been directly related with cancer, mainly breast cancer. The research group has contributed to the better knowledge of the effects and the mechanisms of action of the high corn oil diets, rich in polyunsaturated fatty acids (PUFA) n-6, and the high extra virgin olive oil diets, rich in monounsaturated fatty acids (MUFA) n-9 and several bioactive compounds, in the experimental breast cancer. The aim of this work has been to investigate whether the differentially modulatory effects of these diets, stimulatory and potentially protective respectively, on the promotion of mammary carcinogenesis could be exerted by changes in tumour cell membrane composition. This work is supported on the experimental breast cancer model induced in the female Sprague-Dawley rat with 7,12-dimethylbenz(a)anthracene (DMBA). In order to isolate the different membrane domains, a method for obtaining detergent resistant membranes (DRMs) was standardized in rat liver and, subsequently, it was validated in experimental mammary adenocarcinomas. Next, the lipid content of tumour cell membrane was characterized and, finally, possible changes induced by the different experimental diets on the protein and lipid composition of tumour cell membrane and its different domains were analyzed. The results showed that the mammary tumour cell membranes are rich in cholesterol and ceramide. In addition, the major fatty acids are saturated (SFA), followed by MUFA and, finally, PUFA. This composition was differentially and specifically modified by the effect of dietary lipids. Thus, the high corn oil diet enriched membrane in PUFA n-6, particularly the soluble membrane, besides increasing the cholesterol content, suggesting a greater formation of Chol-Rafts. On the other hand, the high olive oil diet increased the MUFA n-9 levels in domains different than soluble membrane. In addition, this diet increased the sphingomyelin/ceramide ratio, suggesting an increased formation of Cer-Raft, and the levels of the pro-apoptotic protein CD95, and decreased the Cav1 levels in caveolae. Likewise, both diets reduced the palmitic acid content, specially the olive oil diet. These results were in agreement with the greater malignancy, both clinical and morphological, of tumours from animals fed the high corn oil diet and the lower aggressiveness of tumours from the olive oil diet group. Moreover, they were in accordance with the decreased p21Ras activity, the down-regulation of the Akt pathway and the apoptosis induction previously demonstrated for the high olive oil diet.

These diets mostly acted on the carcinogenesis promotion stage, but there are evidences of their action on the initiation stage. The aim of this study was to investigate whether these lipids could exert their modulatory effects through changes on the oxidative stress state in the organism at different levels: in the healthy animal, in the carcinogenesis initiation stage and in the tumor-bearing adult animal. Results proceed from and experimental series, developed in the breast cancer model induced in the Sprague-Dawley rat with the polycyclic aromatic hydrocarbon 7,12-dimethylbenz(a)anthracene (DMBA). The antioxidant enzymatic defense was studied through CAT, SOD1, SOD2, GPX1, GPX4 and GR expression on the liver and mammary gland, and the non-enzymatic defense through total GSH, GSH, GSSG, GSH/GSHtotal and GSH/GSSG glutathione parameters in plasma. Furthermore, plasmatic oxidative damage in lipids and proteins, and DNA damage in the mammary gland though 8-OHdG levels and reparation OGG and PARP reparation damage enzymes were determined. Results showed that, high fat diets increased oxidative levels comparing with the control diet. The high corn oil diet showed a higher effect, both in healthy and especially in the carcinogenesis initiation stage. This was in accordance with an earlier tumor appearance and higher tumor content due to the high corn oil diet. On the other hand, the high extra virgin olive oil diet showed a weak stimulatory c effect which was associated with intermediate oxidative stress levels in serum and liver between the high corn oil and control diets, both in healthy and initiated animals. In the initiated mammary gland, dietary lipids exerted their effects on the oxidative stress parameters through specific mechanisms. Finally, once cancer disease was established, dietary lipids exerted a much lower effect.

These diets mostly acted on the carcinogenesis promotion stage. The aim of this work has been to research on the intervention of these lipids, furthermore, over the initiation through the modulation of the bioactivation and/or detoxification of the carcinogenic initiator agents, both in hepatic level and the mammary gland itself. Results proceed from two different experimental series, developed in the experimental breast cancer model induced in the rat with the polycyclic aromatic hydrocarbon 7,12-dimethylbenz(a)anthracene (DMBA). In both series the xenobiotic metabolizing enzymes (XMEs) were studied, CYP1A1, CYP1A2 and CYP1B1 from the phase I, and GSTP1 and NQO1 from the phase II. The first series analyzed the effect of the dietary lipids on the XMEs expression in the liver and the mammary gland in critical development ages (prepubertal, pubertal and postpubertal/adult). The second series studied specifically the hours immediately after the carcinogen administration and analyzed the effect of the dietary lipids on its hepatic metabolism, the generation of reactive compounds and the genomic damage in the mammary gland. Results showed that dietary lipids may modulate the XMEs expression in different stages of the postnatal development. Additionally, the diet rich in PUFA n-6 increased the expression of phase I enzymes, in ages previous to DMBA administration, and raised CYP1s activity in the hours immediately after induction (12 and 24 hours), while reducing the enzyme activity of phase II, mainly NQO1. The number of reactive metabolites generated in the liver and the genomic damage in the mammary gland of the animals fed the high corn oil diet was higher than in the other groups. On the other hand, the high extra virgin olive oil diet and the normolipidic control diet exhibit a better coordinated phase I and phase II activity, showing a lower production of reactive metabolites and smaller DNA damage in the mammary gland. Concordance between these results and the carcinogenesis parameters in both series showed the effect of lipids on the initiation of the experimental mammary carcinogenesis, besides the already described modulation during promotion/progression stages. Results of this work, along with previous others on the effects of lipids during sexual maturity and mammary gland differentiation suggest that these nutrients, depending on the amount and type, can differently modify the mammary gland susceptibility or resistance to cancer development, and therefore, modulate the windows of susceptibility over the exposure to environmental carcinogens.

Um grande interesse tem sido reportado às proteínas vegetais, em particular as da soja, cujo consumo tem indicado alternativa promissora para prevenção da dislipidemia e aterosclerose. Este estudo investigou o efeito da proteína - conglicinina isolada da soja, frente à resposta de um fármaco hipolipemiante (fenofibrato), em animais submetidos a uma dieta hipercolesterolêmica. Cinquenta e quatro ratos machos Wistar foram divididos em 6 grupos (n=9). O grupo controle (STD) recebeu uma dieta de caseína, e os demais hipercolesterolêmicos (HC), - conglicinina de 200mg/kg (HC+7S1), e 300mg/kg (HC+7S2), fenofibrato de 30mg/kg (HC+FF) e -conglicinina 300mg/kg associada com fenofibrato 30mg/kg (HC+7S2+FF) receberam dieta de caseína suplementada com 1% de colesterol e 0,5% de ácido cólico. Não foram observadas, nos tratamentos, alterações no crescimento, tecido adiposo, consumo e eficiência alimentar. O fenofibrato provocou aumento do peso e da concentração de triglicerídeo hepático. A proteína - conglicinina mostrou reduzir significativamente os efeitos dislipidêmicos séricos e hepáticos provocados pela dieta hipercolesterolêmica; no entanto, não foi observada adição destes efeitos quando associada ao fenofibrato. Os resultados reportados neste estudo sugerem que esta proteína tenha importante ação na regulação do metabolismo lipídico. Tais efeitos podem estar associados a peptídeos desta proteína, muito embora os mecanismos envolvidos não permaneçam completamente esclarecidos.
A great interest has been reported about plant proteins, particularly those of soybean whose consumption has shown potential alternatives to dyslipidemia and atherosclerosis prevention. This study investigated the effect of -conglycinin protein isolated from soybean and its response to hypolipemiant drug (fenofibrate) in animals submitted to a hipercolesterolemic diet. Fifty four male Wistar rats were divided into 6 groups (n = 9). The control group (STD) had received casein diet and the others hypercholesterolemic (HC), -conglycinin of 200mg/kg (HC+7S1) and 300mg/kg (HC+7S2), fenofibrate 30mg/kg (HC+FF) and -conglycinin of 300mg/kg associated to fenofibrate of 30mg/kg (HC+7S2+FF) received casein diet supplemented with 1% of cholesterol and 0.5% of cholic acid. There was no change in growth, adipose tissue, consumption and efficiency food for all treatments. The fenofibrate showed increase in weight and hepatic triglycerides. The -conglycinin protein had showed significantly reduce the effects in dyslipidemic serum and liver caused by hypercholesterolemic diet, however; it was not observed some additional effects when associated with fenofibrate. The results reported in this study suggest that the protein has an important action in the regulation of lipid metabolism. These ones may be associated with their peptides although the mechanisms involved are not already completely understood.

Full textThis dissertation includes 10 publications that are part of the "Fat Diet and Breast Cancer" project developed by the "Grup Multidisciplinari per a l'Estudi Breast Cancer" (GMECM). The studies have used the experimental model of mammary tumors induced in rats with dimethylbenz(α)anthracene (DMBA) and are the result of the following objectives: a) to characterize and to validate morphologically this model, using a unique approach (articles 1 and 2); b) to study the effect of diets rich in corn oil (n-6 PUFA) and extra virgin olive oil (n-9 MUFA and bioactive components) on experimental mammary carcinogenesis, from a histopathologic perspective (articles 2 and 5); c) to analyze the influence of these diets on the expression of p21Ha-Ras, by immunohistochemistry, in experimental breast carcinomas (article 3); d) to apply the morphological contributions in clinical, molecular and biological studies that evaluate breast cancer modulation by dietary lipids (articles 4, 5, 6, 9 and 10); and e) to integrate the results into the mechanisms of the effects of dietary lipids in breast cancer (Articles 7 and 8). First, the morphological approach of experimental mammary tumors and lesions has led two major contributions: a) an optimization of the histological characterization and a proposed classification of experimental breast disease that improve the diagnosis of these lesions and the extrapolation to the human system and b) the design of a grading system for experimental breast carcinomas, based on the Scarff-Bloom-Richardson method, that recognizes tumors with different morphological aggressiveness. Secondly, it has been demonstrated, for the first time, a differential morphological modulation by dietary lipids, on experimental breast carcinomas: an aggressive phenotype (greater architectural, nuclear and histological grades, and an increased mitotic activity, necrosis and stromal desmoplasia) associated with a diet rich in corn oil, particularly when acting as promoter, compared with a normolipidic diet; and a similar appearance of breast carcinomas from the groups fed a diet rich in extra virgin olive oil to the control group ones (low architectural, nuclear and histological grades), and even more benign (a prevailing papillary pattern and a less desmoplastic reaction and tumor necrosis). Third, despite there were no differences in the expression of p21Ha-Ras between experimental groups by the effect of diet, this seems to depend on the histological grade of carcinomas in groups fed normolipidic and corn oil rich diets (increased expression in low histological grade carcinomas). The loss of this relationship by the effect of a diet rich in olive oil is compatible with the attributed role on the activity of the protein. Finally, there has been a correlation of morphological findings with clinical, molecular and biological data, in the integration studies: a) a stimulatory effect of n-6 PUFA (low latency, increased number of affected animals and a high content and tumor volume); and an effect from protective to weakly stimulatory of the extra virgin olive oil (similar tumor latency and lower tumor volume than the control group, but with higher incidence and tumor content); b) a differential expression of PCPH and of newly identified genes (submaxillary gland α-2u globulin, VDUP1, H19 and EST-Rn.32385), related to cell proliferation and differentiation, by dietary lipids; c) an influence of diet rich in n-6 PUFA in the sexual maturation of the animals, advancing puberty and increasing the risk of breast cancer.
