Association of plasma markers of cholesterol homeostasis with metabolic syndrome components. A cross-sectional study.
Abstract Background and aims Increased plasma phytosterols, which reflect enhanced cholesterol absorption, have been related to an increased risk of cardiovascular disease (CVD). However, high CVD risk conditions, such as obesity, diabetes and the metabolic syndrome (MetS) have been associated with reduced cholesterol absorption. We investigated associations between plasma noncholesterol sterols and MetS components. Methods and results With a cross-sectional design, we related MetS components to plasma noncholesterol sterol-to-cholesterol ratios measured by gas chromatography in 674 dyslipidemic patients and 361 healthy subjects participating in a prospective cohort study. Plasma phytostero…
Fitoesteroles plasmáticos: marcadores de una dieta saludable y un riesgo cardiometabólico menor en la población española del estudio EPIC
Resumen Introduccion Las concentraciones elevadas de fitoesteroles plasmaticos, que reflejan una mayor absorcion intestinal de colesterol se han relacionado con un aumento del riesgo cardiovascular. Sin embargo, una situacion de riesgo alto, el sindrome metabolico (SM), se asocia a un aumento de la sintesis y una disminucion de la absorcion de colesterol y, por tanto, a una menor fitoesterolemia. En este estudio hemos investigado la relacion entre los fitoesteroles del plasma y la dieta y la presencia de factores de riesgo cardiovascular, incluidos los componentes del SM. Metodos y resultados En un estudio transversal, se evaluaron la ingesta de fitoesteroles y concentraciones plasmaticas d…
Phytosterol plasma concentrations and coronary heart disease in the prospective Spanish EPIC cohort
Phytosterol intake with natural foods, a measure of healthy dietary choices, increases plasma levels, but increased plasma phytosterols are believed to be a coronary heart disease (CHD) risk factor. To address this paradox, we evaluated baseline risk factors, phytosterol intake, and plasma noncholesterol sterol levels in participants of a case control study nested within the European Prospective Investigation into Cancer and Nutrition (EPIC) Spanish cohort who developed CHD (n = 299) and matched controls (n = 584) who remained free of CHD after a 10 year follow-up. Sitosterol-to-cholesterol ratios increased across tertiles of phytosterol intake (P = 0.026). HDL-cholesterol level increased, …
