Antioxidant Beverages: Green Tea Intake and Coronary Artery Disease
نویسندگان
چکیده
Coronary artery disease (CAD) is recognized as an inflammatory disease. In the present study, we investigated the effect of green tea consumption on plasma inflammatory markers and the association between green tea consumption and CAD. In 22 healthy volunteers, green tea consumption (7 cups/day) significantly decreased serum malondialdehyde-modified low-density lipoprotein (MDA-LDL) concentrations, whereas green tea consumption tended to decrease plasma C-reactive protein and interleukin (IL)-6 concentrations. In 725 patients undergoing coronary angiography, the percentage of patients drinking <1 cup/day of green tea was higher in patients with myocardial infarction (MI) than in CAD patients without MI and patients without CAD (29% vs. 15% and 18%, P < 0.01). Green tea consumption was found to be inversely associated with MI in Japanese patients. The protective effect of green tea against atherosclerosis is more likely to be because of the inhibitory effect of LDL oxidation than because of anti-inflammatory effect.

Tea catechin consumption reduces circulating oxidized low-density lipoprotein.
It has been reported that green tea consumption reduces the risk of coronary artery disease and cardiac events. Catechin is a major constituent of Japanese green tea and an antioxidant. Lipids and oxidization of low-density lipoprotein cholesterol (LDL-C) play important roles in atherosclerosis. Therefore, we evaluated the effect of catechin intake on the lipid profile and plasma oxidized LDL. ...

متن کاملGreen tea reverses endothelial dysfunction in healthy smokers.
G reen tea is popular in Asia, including Japan, although it is rarely consumed by western people. It contains large amounts of catechins which are potent free radical scavengers and therefore has an antioxidant effect. Oxidative stress participates in the pathogenesis of many cardiovascular diseases. Recently, black tea consumption has been shown to reverse endothelial dysfunction in patients w...

متن کاملShort- and long-term black tea consumption reverses endothelial dysfunction in patients with coronary artery disease.
BACKGROUND Epidemiological studies suggest that tea consumption decreases cardiovascular risk, but the mechanisms of benefit remain undefined. Endothelial dysfunction has been associated with coronary artery disease and increased oxidative stress. Some antioxidants have been shown to reverse endothelial dysfunction, and tea contains antioxidant flavonoids. Methods and Results-- To test the hypo...
