Postprandial oxidative stress is characterized by an increased susceptibility of the organism towards oxidative damage after consumption of a meal rich in lipids and/or carbohydrates. Micronutrients modulate immune system and exert a protective action by reducing low density lipoproteins (LDL) oxidation via induction of antioxidant enzymes.

Lo stress ossidativo postprandiale è caratterizzato da una maggiore suscettibilità dell'organismo verso il danno ossidativo dopo il consumo di un pasto ricco di lipidi e / o carboidrati. Micronutrienti modulano il sistema immunitario ed esercitano un'azione protettiva riducendo lipoproteine a bassa densità (LDL) ossidazione attraverso l'induzione di enzimi antiossidanti. Abbiamo valutato l'espressione del gene dello stress ossidativo (Hosp), inflammasome (anca), e percorsi di metabolismo dei farmaci umani (HDM) e il livello di ox-LDL al basale e dopo l'assunzione di vino rosso naturalmente arricchito con resveratrolo (NPVRW), in associazione con o senza pasto al McDonald (MCDM). I livelli di ox-LDL significativamente aumentare il confronto di base (B) contro MCDM e una diminuzione confrontando MCDM contro MCDM + NPVRW ( ≤ 0,05). Studi cronici su una popolazione più ampia sono necessari prima di trarre conclusioni definitive.

Abstract
Postprandial oxidative stress is characterized by an increased susceptibility of the organism towards oxidative damage after consumption of a meal rich in lipids and/or carbohydrates. Micronutrients modulate immune system and exert a protective action by reducing low density lipoproteins (LDL) oxidation via induction of antioxidant enzymes. We evaluated the gene expression of oxidative stress (HOSp), inflammasome (HIp), and human drug metabolism pathways (HDM) and ox-LDL level at baseline and after the intake of red wine naturally enriched with resveratrol (NPVRW), in association with or without a McDonald’s meal (McDM). The ox-LDL levels significantly increase comparing baseline (B) versus McDM and decreased comparing McDM versus McDM+NPVRW( ≤ 0.05). Chronic studies on larger population are necessary before definitive conclusions.File | Dimensione | Formato | |
