Effect of acute and chronic red wine consumption on lipopolysaccharide concentrations.

Ingestion of red wine significantly increases plasma phenolic acid concentrations but does not acutely affect ex vivo lipoprotein oxidizability.

BACKGROUND Reduced lipoprotein oxidizability by red wine phenols has been proposed as the basis for a relatively lower incidence of coronary heart disease in red wine drinkers. We showed previously that caffeic and protocatechuic acids isolated from red wine exhibit antioxidant activity in vitro. However, there is no information in the literature on the absorption of these compounds after red w...

Antioxidant and Anti-Inflammatory Effects in RAW264.7 Macrophages of Malvidin, a Major Red Wine Polyphenol

BACKGROUND Red wine polyphenols can prevent cardiovascular and inflammatory diseases. Resveratrol, the most extensively studied constituent, is unlikely to solely account for these beneficial effects because of its rather low abundance and bioavailability. Malvidin is far the most abundant polyphenol in red wine; however, very limited data are available about its effect on inflammatory processe...

Comparison Between Effect of Grape Fermentative Product (red wine) and Fresh Red Grape Juice on Antioxidant Biomarkers of Liver Mitochondria Isolated from Rats in vitro

Effect of an acute consumption of a moderate amount of ethanol on plasma endocannabinoid levels in humans.

AIMS Animal experiments have shown that the endocannabinoid system (ECS) plays an important role in the regulation of ethanol intake. We investigated these effects in healthy volunteers who consumed a moderate amount of ethanol (red wine) and measured plasma levels of the endocannabinoids (ECs) anandamide (AEA) and 2-arachidonoylglycerol (2-AG) to test whether alcohol consumption influences the...

The influence of moderate red wine consumption on antioxidant status and indices of oxidative stress associated with CHD in healthy volunteers.

The effects of moderate red wine consumption on the antioxidant status and indices of lipid peroxidation and oxidative stress associated with CHD were investigated. A randomised, controlled study was performed with twenty free-living healthy volunteers. Subjects in the red wine group consumed 375 ml red wine daily for 2 weeks. We measured the total concentration of phenolics and analysed the in...
