Red wine consumption effect on lipids and oxidative stress biomarkers

Red wine consumption effect on lipids and oxidative stress biomarkers

  • 22 February 2016

Postprandial lipemia has been recognized as a risk factor for atherosclerosis development. Consuming meals with suitable sources of antioxidants such as red wine reduces postprandial oxidative stress. However, information about the postprandial effects of wine ingestion outside meals on lipids and on in vivo low-density lipoprotein (LDL) oxidation in humans is scarce.

This was one of the first studies, back in 2003, and the aim of this study was to investigate postprandial changes in lipids and in vivo LDL oxidation after moderate (250 ml) red wine ingestion, before and after sustained wine consumption of 250 ml/day for 4 days. After 4 days of sustained wine consumption, a decrease in the LDL/high-density lipoprotein cholesterol ratio was observed after wine ingestion (p = 0.026). On day 4, a decrease in oxidized LDL levels and an increase in the antioxidant enzyme glutathione peroxidase activity (p = 0.025) were observed after wine ingestion. Our results show that consumption of red wine at moderate doses outside meals does not promote oxidative stress. Daily consumption of moderate doses of red wine can improve postprandial lipid profile and oxidative status when the wine is ingested outside meals.
