Fatty Acids Composition of Blood Cell Membranes and Peripheral Inflammation in the PREDIMED Study: A Cross-Sectional Analysis
There is limited evidence from epidemiological studies for the inflammatory or anti-inflammatory properties of fatty acids in blood cell membranes. Therefore, this study examined associations between baseline (n = 282) and 1-year (n = 143) changes in the levels of fatty acids in blood cell membranes with circulating inflammatory markers in older adults at high cardiovascular risk. The data for this cross-sectional analysis was obtained from a case-control study within the PREDIMED study. Linear regression with elastic net penalty was applied to test associations between measured fatty acids and inflammatory markers. Several fatty acids were associated with interferon-&gamma
Effect on gut microbiota of a 1-y lifestyle intervention with Mediterranean diet compared with energy-reduced Mediterranean diet and physical activity promotion: PREDIMED-Plus Study
ABSTRACT Background The Mediterranean diet is a well-recognized healthy diet that has shown to induce positive changes in gut microbiota. Lifestyle changes such as diet along with physical activity could aid in weight loss and improve cardiovascular risk factors. Objectives To investigate the effect of an intensive lifestyle weight loss intervention on gut microbiota. Methods This is a substudy of the PREDIMED-Plus (Prevención con Dieta Mediterránea-Plus), a randomized controlled trial conducted in overweight/obese men and women (aged 55–75 y) with metabolic syndrome. The intervention group (IG) underwent an intensive weight loss lifestyle intervention based on an energy-restricted Mediterr…
Cross-Sectional Associations between HDL Structure or Function, Cell Membrane Fatty Acid Composition, and Inflammation in Elderly Adults.
Background Cell membrane fatty acid composition has been related to inflammation and cardiovascular risk. Dysregulation of HDL functionis also considered a cardiovascular risk factor. Objective We aimed to investigate whether the content of cell membrane fatty acids and HDL functionality are linked to each other as well as to inflammation. Methods This cross-sectional analysis involved 259 participants (67.9 y) with overweight/obesity (body mass index 29.5 kg/m2) from a coronary heart disease case-control study nested within the PREDIMED trial for which HDL functional parameters (Apolipoproteins (Apo) A-1, A-IV and C-III, cholesterol efflux capacity (CEC), HDL oxidative inflammatory index (…
Association Between Fatty Acids of Blood Cell Membranes and Incidence of Coronary Heart Disease
Objective— To examine the associations between baseline levels of fatty acids in blood cell membranes and their 1-year changes with the incidence of coronary heart disease (CHD) in older adults at high cardiovascular disease risk. Approach and Results— This is a case-control study nested in the PREDIMED trial (Prevención con Dieta Mediterránea), with 136 CHD cases and 272 controls (matched on age, sex, body mass index, intervention group, and time of permanence in the study to the time event). We used gas chromatography to measure the proportion of 22 fatty acids in blood cell membranes at baseline and after 1 year. Conditional logistic regression was used to estimate odds ratios (ORs) and…
