Filter by:Essential polyunsaturated fatty acids (EFAs) have a significant impact on human health, even before birth. Their supplementation is recommended at all ages, especially in people with cardiolovascular risks. The most valuable proven action of EFAs is the improvement of the lipid profile (including increase in HDL, the so-called "good cholesterol" and lowering LDL, the so-called "bad cholesterol"), preventing the development of atherosclerosis, strokes and heart attacks. We distinguish three fractions of EFAs: EPA, DHA and ALA. The best known are EPA and DHA, but in recent years the interest in ALA fraction has increased, as it is the only fraction that has pronounced anti-inflammatory properties, but also only ALA is not produced by the human body and must be supplied with food. We believe that the supplementation of the ALA fraction is as important as the supplementation of the well-known and recommended EPA and DHA fractions, moreover it also brings unique benefits. The aim of the study is to demonstrate the benefits of EFAs in the prevention of cardiovascular diseases in the group of adults. In the project, we also want to compare the benefits of supplementing various fractions. Each volunteer will be randomly assigned to one of 4 groups. Group No. 1 will be a group without the supplementation of essential fatty acids (EFAs), group No. 2 will receive supplementation with pure ALA fraction, group No. 3 will receive supplementation with EPA and DHA fractions, and group No. 4 will receive supplementation with all fractions, i.e. ALA, EPA and DHA. All persons from groups 1-4 will be examined three times: at the beginning, after three months and after six months (at the end of the project). The tests will include: blood pressure measurements, non-invasive measurements of body mass and composition, and laboratory tests: CRP, fasting glucose, lipid profile, and blood count. Both preparations for acid supplementation and tests are completely free for participants. Participation in the study is voluntary and is not associated with any health risk.
Interactions between genes and environment, are likely to be crucial in the development of the common diseases such as type 2 diabetes. Recently, the investigators have obtained data that genotypes of genes encoding for fatty acid desaturases 1 and 2 (FADS1 and FADS2) are the strongest genes in a genome-wide analysis regulating serum fatty acid profile.The aim of this study is to test if subjects with different genotypes of the FADS2 gene respond differently to a diet supplemented with linoleic acid or alpha-linolenic acid (substrates for FADS2). The study hypothesizes that subjects will be more sensitive to the dietary modifications according to their genotype leading to more robust differences in serum FA profile, tissue inflammation and serum lipids.
Introduction: The metabolism of fatty acids in plasma is modulated by their availability in plasma. Individuals with increased weight have increased plasma fatty acids and physical exercise seems to favor the metabolic responses of fatty acid mobilization. Objective: To test the hypothesis that the physical exercise of acute way changes the fatty acids of medium chain of the serum of individuals with increase of the corporal weight. Method: Including 66 women, randomly divided into two groups, control and experiment, overweight, sedentary, and between 18 and 30 years of age. After a 12-hour fast, basal blood collection will be performed. The experiment group, 12 hours after the first collection, will be submitted to a physical exercise session with energy expenditure of 250Kcal. The volunteers in the control and experiment group will make a second blood collection 24 hours after the first one. The fatty acids will be dosed: pelargonic, azelaic, elaidic and oleic by gas chromatography. Intra and intergroup comparisons will be made using the t test for independent and dependent samples, p <0.05.
The objective of the study is to assess the effect of two diets with different fat composition on cholesterol metabolism. The study was a randomized cross-over trial where volunteers follow two study periods with different types of meat (lean and fat red meat) separately by a ten days wash-out period. At the beginning of the study and after the study periods the following parameters are determined: anthropometric (weight, waist, circumference and body mass index), blood pressure, dietary (72-hours dietary registry) and exercise assessments and biochemical analysis (total cholesterol, triglycerides, HDL cholesterol, LDL cholesterol, apolipoprotein A1, apolipoprotein B, iron, transferring, ferritin, uric acid, glucose, HbA1c and insulin). Serum concentration of non cholesterol sterols (sitosterol, campesterol, stigmasterol, desmosterol and lanosterol) and oxysterols (24S-hydroxycholesterol, 27-hydroxycholesterol and 7α-hydroxycholestenone) were measured by High Performance Liquid Chromatography tandem Mass Spectrometry in these subjects throughout along the study in order to demonstrate the effect of different red meat on the hepatic metabolism of cholesterol.
The main objective is to evaluate the effects of omega-3 fatty acids on hot flashes frequency.
