Green Tea Lowers Cholesterol, Improves Blood Sugar

A University of Southern California study of 103 postmenopausal women found that green tea lowered LDL cholesterol and improved blood sugar metabolism over an eight-week period.
The most active component of green tea is the antioxidant catechin called epigallocatechin gallate (EGCG). In the study, 1/3 of the women consumed 400 mg of EGCG per day, 1/3 had 800 mg of EGCG, and the other 1/3 were the control group. It is well known that metabolism in postmenopausal women can go on the blink; thus, the lowered LDL cholesterol and improved blood sugar metabolism study results show that green tea can be quite helpful.
I have previously reported that green tea can help lower cholesterol, explaining various mechanisms in my article How Green Tea Improves Cholesterol Metabolism.
This study also indicates improvement in blood sugar metabolism. It is well established that green tea reduces the risk for diabetes. Researchers continue to try to understand how green tea improves glucose metabolism.
One animal study shows that green tea protects pancreatic beta cells and helps preserve normal pancreatic insulin production. Another study reveals that green tea improves the fitness of fat, helping glucose metabolize normally within white adipose tissue, while reducing inflammation in fat tissue. Yet another study shows that green tea boosts adiponectin, a key hormone that prevents insulin resistance.
The science supporting the health benefits of green tea keeps coming. Each new study helps paint a picture of the multiple ways in which green tea improves both cholesterol and blood sugar. It is now clear that EGCG is an effective nutrient for keeping your metabolism running smoothly.
