Green Tea Extract is heart healthy for women
Fourteen healthy women who were not taking any medication were placed on a Green Tea Extract for five weeks. When the women were on Green Tea Extract there blood flow and blood vessel function was much better than when they were on placebo.
The LDL-cholesterol in plasma should not be oxidized. When it is oxidized it goes rancid and becomes unstable and damages blood vessel walls. Oxidation of LDL contributes to the development of atherosclerosis. Immune cells in the lining of blood vessel walls known as macrophages have a tendency to remove oxidized LDL, and these cells become loaded with damaged lipids, and convert into "foam cells" or fatty laden cells. Foam cells accumulate in fatty streaks on blood vessel walls, early signs of atherosclerosis (hardening of blood vessel walls). When the women were consuming the Green Tea Extract they had a 37.4% drop in their level of oxidized LDL. The study is published in the current issue of the Journal of the American College of Nutrition, 2008;27(2).
