Recently Discovered Health Benefit of Green Tea in Experimental Medicine

Recently Discovered Health Benefit of Green Tea in Experimental Medicine

More and more benefits have been shown with green tea, which is one of main ingredients in MetaboSlim. Recently, scientists demonstrate additional health benefits of green tea in preventing stroke, weight-loss properties and anti-oxidative stress in experimental animals.

More and more benefits have been shown with green tea, which is one of main ingredients in MetaboSlim. Recently, a group of scientist at Fuji Tokoha University, Japan published their research results in Med Sci Monit (2007).

In their research, 0.5% green tea catechin extract (polyphenon) was given to rats with malignant stroke-prone spontaneously hypertensive. It is found that tea catechin intake significantly delayed stroke onset compared to the control group. The rate in blood pressure increase in the tea catechin group was significantly smaller than that in the control group. Continuous ingestion of green tea catechins from an early age prevented the development of spontaneous stroke in rats, probably by inhibiting the further development of high blood pressure at later ages.

Chinese scientists at Chinese Academy of Sciences, Guangzhou have shown that green tea extract intake is associated with increased weight loss due to diet-induced thermogenesis, which is generally attributed to the catechin epigallocatechin gallate. That catechin-polyphenols are known to be capable of inhibiting catechol-O-methyltransferase (the enzyme that degrades norepinephrine) is a possible explanation for why the green tea extract is effective in stimulating thermogenesis by epigallocatechin gallate to augment and prolong sympathetic stimulation of thermogenesis. Knowledge about thermogenesis-induced weight loss produced by green tea's epigallocatechin gallate and its ability to inhibit catechol-O-methyltransferase is important for health benefits and for prolonging the action of norepinephrine in the synaptic cleft. Similar findings were published recently by Dr. Diepvens at Department of Human Biology, Maastricht University, The Netherlands in American Journal of Physiology. In this publication, positive effects on body-weight management have been shown using green tea mixtures. Green tea, by containing both tea catechins and caffeine, may act through inhibition of catechol O-methyl-transferase, and inhibition of phosphodiesterase. Here, the mechanisms may also operate synergistically.

In addition, tea catechins have antiangiogenic properties that may prevent development of overweight and obesity. Furthermore, the sympathetic nervous system is involved in the regulation of lipolysis, and the sympathetic innervation of white adipose tissue may play an important role in the regulation of total body fat in general.
