Another study shows that Green Tea burns calories and reduces body fat in obese people
Medical researchers in Thailand placed 60 obese subjects on the same controlled diet; one group was placed on a Green Tea regimen and the other was given inactive, look and taste alike placebo. By the 12th week of the study those on the diet with Green Tea lost 7.26 more pounds than those on the diet alone. There was no difference in level of satiation, amount of physical activity, or calorie intake between the two groups. The Green Tea achieved its effect by burning more calories and reducing body fat levels. The study is published in the October 18th 2007 issue of the American Journal Physiology and Behavior.
Green Tea reduces the risk of developing a cold or flu infection
In this newly published study healthy subjects between the ages of 18 to 70 were given either inactive placebo or a standardized Green Tea Capsule twice a day for 3 months. The researchers from Harvard and the University of Florida, Gainesville show that Green Tea capsules strongly improve the ability of the immune system to fight an infection compared to placebo by increasing the proliferation of gamma-delta T cells that recognize and fight cold and flu infections by 28%; this is very important because this is among the earliest activity of the immune system that possibly occurs before antibodies are formed by the memory portion of the immune system. Green Tea capsules also improved the production of interferon gamma by 26%; gamma interferon suppresses viral activity.
Green Tea capsules reduced the number of people with any symptoms by 32%, reduced the number of illnesses with at least 2 days duration by 23% and reduced the number of days with symptoms by 36%. The study is published in the October 2007 issue of the Journal of the American College of Nutrition.
