Green Tea Consumption Lowers Total and LDL Cholesterol Levels
The study grouped the results from twenty past research bodies covering a total of 1,415 participants. Once compiled and analyzed, the pooled data found that green tea catechins, at doses ranging from 145 to 3,000 mg per day (including consumption as green tea beverage and extract in capsules), led to statistically significant reductions in total and LDL ("bad") cholesterol, compared to controls who did not consume any. The studies reviewed ranged from three to twenty-four weeks in duration. Interestingly, they did not show any change in HDL cholesterol or triglyceride levels.
The results demonstrated that green tea in the form of a beverage yielded minimally improved levels of lipid improvement compared with capsule supplements. Total and LDL cholesterol levels were improved an average of five to six points, a statistically significant reduction in those at increased risk for heart disease and heart attack. While this analysis did not specify LDL particle size, previous research studies have demonstrated that green tea consumption results in larger, less atherogenic particles that do not raise disease risk.
Increased risk factors for cardiovascular disease include smoking, high blood pressure, low HDL cholesterol, and age. Alternative natural therapies including green tea consumption or supplementation offer a potent weapon in the fight against lipid-mediated risk factors and heart disease. Green tea can contain fluoride absorbed from the environment, so be certain to select an organically harvested green tea variety from a trusted supplier.
