As our community is becoming richer, people are more health sensible nowadays. In term of drink, green tea is treated as the healthiest drink as it is not only has the rehydrate function, but it is also flavonoid rich that manage to protect our body against heart syndrome.
Experimentation on green tea drinkers indicate that they are significantly less vulnerable to a lot of ailment, from viral infection to chronic degenerative ailment like stroke, cancer, heart disease and osteoporosis.
Research indicates that green tea has incredibly high level of flavonoids (antioxidant) which consist of catechins and their derivatives. Antioxidant is the biological event that inhibits the oxidation which will develop highly reactive free radicals. Flavonoids substance comprises of larger than 1/3 of the green tea dry weight. Epigallocatechin-3-gallate (EGCG) is the largest abundant catechin in all green tea. It has the highest antioxidant activity of all green tea's catechins and hence is thought to play the most significant role in the green tea's anticancer and antioxidant effect. Green tea EGCG is so rich that a cup of green tea could have 20-35mg of it.
In our arteries, there is a one cell thick lining that works as the boundary layer between the bloodstream and the wall of the artery where blood plaques may form, this is called arterial endothelium. When cardiovascular disease happens, a kind of enzyme will speed up the production of free radicals in the artery endothelium, thus rises the level of free radicals in arteries intensely. Green tea EGCG will inhibit the enzymes needed in the production of the free radicals and thus protects the endothelium from injured by free radical. And so green tea is acting a critical role in controlling cardiovascular disease.
EGCG also helps in halting the death of heart muscle cells following ischemia/reperfusion injury, by obstructing the activation of inflammation compounds (STAT-1) that will cause oxidative injury which kills heart cell in reperfusion injury.
Besides, cancer cells need enzyme dihydrofolate reductase (DHFR) to build DNA and multiply. EGCG will inhibit the DHFR and is effectively stopping the grow of cancer cells.
Furthermore, EGCG can also hasten the recovery of injured heart cells, and thus allowing fast recovery of tissues and remedying organs injury.
In conclusion, green tea EGCG has grand benefit in helping heart disease controlling as well as in heart illness damage recovery. Therefore for those who are suffering from heart disease and those who are health sensitive, green tea is the best choice of beverage for them. Having few cups of green tea, primarily decaf green tea a day instead of decaffeinated coffee will definitely ensure our long term health.
