“…In the case of the liver, fat accumulation is detected as hepatic steatosis, characterized by the accumulation of VLDL particles, which cause liver increase with a weight 5% higher than the reference rate (Almeida et al, 2011). However, treatment with different types of oils or fats in current study did not cause changes in the weight of liver, heart and other organs analyzed.…”

“…Coconut oil is comprised of approximately 44% saturated fatty acids and 66% unsaturated fatty acids (Machado, Chaves, & Antoniassi, 2006), with a composition similar to that of lard, which has a higher acid content because of a higher saturated fat percentage (45.05%) than unsaturated fatty acids (54.95%). The composition is the reverse of soybean oil, which has lower amounts of saturated fatty acids (14.19%) when compared to unsaturated fatty acids (85.49%) (Almeida, Queiroz, Costa, & Matta, 2011). This fact influences many physiological mechanisms, such as the regulation of the activity of pancreatic lipase and, as a result, the digestibility of lipids (Ricketts & Brannon, 1994).…”

ABSTRACT. Changes in body composition and serum lipid profile in rats, supplemented with coconut oil, are evaluated and compared to other lipid sources. Female Wistar rats received by gavage 1 mL kg -1 of saline, soybean oil, lard or coconut oil during 21 days. At the end of the study period, body composition, food intake, feces, urine, organ weight and serum lipid profile were assessed. No statistical differences between the groups were found in body composition, food intake, fecal and urinary analysis, and organ weight. In the case or plasma lipid concentrations, coconut oil and lard raised total cholesterol levels, without changes in LDL levels. On the other hand there was no change in total cholesterol levels in the soybean oil group. HDL fraction increased in all groups when compared to that in the saline group; this increase was more significant in the coconut oil group. There was significant reduction of serum triglycerides only in the coconut oil group when compared to the saline group. Supplementation with coconut oil did not interfere in weight and body composition of the animals used in current study, but revealed significant effect on the increase of HDL-c levels and decrease of serum triglycerides.Keywords: dyslipidemias, body composition, oils.Óleo de coco aumenta o HDL-c e reduz os triglicerídeos séricos em ratas Wistar RESUMO. Analisar as alterações na composição corporal e no perfil lipídico sérico de ratas suplementadas com óleo de coco, comparativamente a outras fontes lipídicas. Foram utilizadas ratas Wistar, as quais receberam via oral 1 mL kg -1 de solução salina, óleo de soja, gordura de porco ou óleo de coco por 21 dias. Ao término avaliaram-se a composição corporal, o consumo alimentar, as fezes, a urina, o peso de órgãos e o perfil lipídico sérico. Não houve diferença estatística entre os grupos com relação à composição corporal, ao consumo alimentar, à análise de fezes e à urina, e peso de órgãos. Quanto às concentrações de lipídios plasmáticos, o óleo de coco e a gordura de porco elevaram o colesterol total, sem alteração dos níveis de LDL, quando comparados ao grupo salina. Em todos os grupos foi observada elevação da fração HDL, sendo mais significativa no grupo óleo de coco, quando comparados ao grupo salina. Ainda, se comparado ao grupo salina, apenas no grupo óleo de coco houve redução significativa das concentrações séricas de triglicerídeos. A suplementação com óleo de coco não interferiu no peso e composição corporal dos animais em estudo. No entanto esta suplementação apresentou importante efeito no aumento do HDL-c e na redução dos triglicerídeos séricos.Palavras-chave: dislipidemias, composição corporal, óleos.

“…These results may be explained by the composition of vegetable oils used, as buriti oil has 4.6% saturated fatty acids, 91.6% monounsaturated fatty acids and 3.8% polyunsaturated fatty acids and soybean oil shows 31.7% saturated fatty acids, 23.6% monounsaturated fatty acids and 44.7 % polyunsatu rated fatty acids (14,15,21). Diets added of soybean oil and buriti oil of high concentration of polyunsaturated and monounsatu rated fatty acids, respectively, should be consumed because they have antiatherogenic, vasodilator and an tiplatelet action (22). The guidelines for proper fatty acids consumption suggest consumption according to the total caloric value of the diet from lipids with 7% of calories from saturated fatty acids, 15% from monoun oxidation (27).…”

Objectives:To compare the effect of the consumption of buriti oil and soybean oil on the metabolism of rats under stress induced by iron overload. Materials and methods: A total of 28 rats were randomized into control groups who consumed diet added of soybean (CS) or buriti oil (CB) and gavage with saline and two experimental groups who consumed diet added of soybean (ES) or buriti oil (EB) and daily gavage with iron II sulfate as stress inducer. The fatty acid profile of diets was analyzed. Body weight and diet consumption were evaluated every two days. The lipid profile and liver weight of animals were evaluated at the end of the experiment. Results: Diet added of soybean oil showed higher percentage of polyunsaturated fatty acids (45.6%) and diet with buriti oil was rich in monounsaturated fatty acids (66.9%). There were no differences in food intake, total cholesterol, HDL-cholesterol and LDL-cholesterol among groups (p > 0.05). However, animals fed with diet supplemented with buriti oil showed intermediate triglyceride levels (CB: 65 mg/dL; EB: 68.7 mg/dL) compared to ES group (102.5 mg/dL). The liver of rats from the CS group had higher weight (2.06 ± 0.2 g) compared to the CB group (1.56 ± 0.1 g). Conclusion: Buriti oil consumption was able to minimize some changes related to iron overload. Arch Endocrinol Metab. 2015;59(5):422-7

“…Al relacionar la variable CT con los TAG se obtuvo que los grupos que consumieron dietas con tomate y tomate de árbol, presentaron un mayor valor estadísticamente signifi cativo (p<0,05) en relación al consumo de DB y similar al reportado en la literatura para animales alimentados con aceite de soya (34). Este resultado es el refl ejo del efecto de la dieta sobre la disminución de los triglicéridos.…”

INTRODUCCIÓNLa tasa de mortalidad cardiovascular en los países en desarrollo ha presentado un incremento signifi cativo en los últimos años. En Venezuela, constituye la primera causa de muerte en la población, representando 21% de la mortalidad diagnosticada (1). En América Latina también se evidencia un aumento signifi cativo de dichas enfermedades asociado a cambios en los estilos de vida, aumento demográfi co y una transición epidemiológica y nutricional (2).En un estudio de casos de factores de riesgo sobre estas enfermedades (Interheart) (2), se demostró, que a nivel mundial el incremento en los lípidos sanguíneos, fue el factor más importante, tanto en hombres (49,5%) como en mujeres (47,1%). En América Latina, el mayor riesgo se debió a obesidad abdominal (45,8%). Dentro de algunos parámetros evaluados que tuvieron un efecto protector, se señalan el consumo diario de frutas y/o verduras y el ejercicio.El informe sobre "Dieta, Nutrición y Prevención de Enfermedades Crónicas" publicado por WHO/FAO el año 2003 (3), Rev Chil Nutr Vol. 40, Nº4, Diciembre 2013 Efecto de la ingesta de dietas con tomate (Lycopersicum esculentum) y tomate de árbol (Cyphomandra betacea (Cav.) Sendtn) en los lípidos sanguíneos de ratas Effect of dietary intake of tomato (Lycopersicum esculentum) and tree tomato (Cyphomandra betacea (Cav.) Sendtn) on blood lipids in rats Este trabajo fue recibido el 9 de Julio de 2013 y aceptado para ser publicado el 1 de Noviembre de 2013. ABSTRACT Consumption of tomato (Lycopersicon esculentum ) and tree tomato ( Cyphomandra betacea ) is interesting for its nutritional composition and content of antioxidant compounds. Thisresearch evaluated the effect of diets intake with tomatoes on blood lipids in rats. First, fatty acids were determined in tomato seeds. Subsequently, rats (Sprague-Dawley, 6 females per group , 2 months old and weight 160 g ) were fed with basal diet (AIN-93M) supplemented with 10% tomato and tomato tree at the expense of starch for 5 weeks. Effi ciency and diet digestibility were calculated. Triglycerides (plasma), total cholesterol (serum), HDL (plasma) were measured and LDL was calculated. Results showed that seeds of C. betacea 7% had more polyunsaturated fatty acids than L. esculentum. Consumption of diets with both fruits decreased triglycerides and LDL and increased HDL. The results indicate the importance of encouraging the consumption of these fruits as a contribution to the prevention of some chronic diseases.
