Black tea consumption does not protect low density lipoprotein from oxidative modification

Article Abstract:

The influence of black tea on the oxidative modification of low density lipoprotein (LDL) in vivo and in vitro was studied. The antioxidant effects of black tea were determined by measuring the resistance of the LDL to oxidative modification in the presence of copper. Findings indicated that black tea extracts enhanced the resistance of LDL in vitro depending on concentration. The change in total plasma antioxidant capacity or susceptibility of the LDL to oxidation over the three-hr period after drinking black tea was minimal.

Enhanced plasma level of lipid peroxidation in Iranians could be improved by antioxidants supplementation

Article Abstract:

Beta-carotene supplementation with or without alpha-tocopherol was found to reduce high levels of plasma malondialdehyde (MDA) of Iranians. Findings revealed that decreased MDA level was associated with an increased titre of circulating autoantibodies to oxidatively modified low density lipoprotein which has been shown to be a risk factor in the development of coronary heart disease. Alpha-tocopherol is a very effective antioxidant especially with regards to inhibition of MDA formation.

Moderate consumption of beer, red wine and spirits has counteracting effects on plasma antioxidants in middle-aged men

Article Abstract:

Research is presented describing the effects on plasma antioxidantation of drinking moderate amounts of alcoholic beverages with an evening meal. The subjects of the study were all healthy, non-smoking middle aged men.
