As the public is becoming richer, people are more health conscious nowadays. In term of beverage, green tea is treated as the healthiest drink as it is not only has the rehydrate ability, but it is also flavonoid rich that can save our body against cardiovascular syndrome.

Experimentation on green tea drinkers suggest that they are somewhat less vulnerable to a wide range of ailment, from virus infection to chronic degenerative illness like stroke, cancer, cardiovascular disease and osteoporosis.

Study illustrates that green tea has incredibly high level of flavonoids (antioxidant) including catechins and their derivatives. Antioxidant is the biological event that prevents the oxidation which will yield highly reactive free radicals. Flavonoids substance consists of larger than 1/3 of the green tea dry weight. Epigallocatechin-3-gallate (EGCG) is the most 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 paramount role in the green tea's anticancer and antioxidant effect. Green tea EGCG is so abundant that a cup of green tea might have 20-35mg of it.

In our arteries, there is a one cell thick lining that acts as the boundary layer between the bloodstream and the wall of the artery where blood plaques could form, this is known as arterial endothelium. When cardiovascular disease occurs, a form of enzyme will spur the production of free radicals in the artery endothelium, thus amplifies the level of free radicals in arteries abruptly. Green tea EGCG will inhibit the enzymes needed in the production of the free radicals and thus shields the endothelium from injured by free radical. Because of this green tea is playing a vital role in preventing cardiovascular disease.

EGCG also helps in preventing the death of heart muscle cells following ischemia/reperfusion injury, by stopping the onset of inflammation compounds (STAT-1) that will induce oxidative damage which kills heart cell in reperfusion injury.

Moreover, cancer cells require enzyme dihydrofolate reductase (DHFR) to make DNA and spread. EGCG will interfere with the DHFR and is effectively prevents the grow of cancer cells.

Furthermore, EGCG can also facilitate the salvage of damaged heart cells, and accordingly allowing speedy recovery of tissues and attenuating organs injury.

In conclusion, green tea EGCG has great benefit in helping heart disease controlling as well as in heart illness damage recovery. As such for those who are suffering from cardiovascular disease and those who are health sensitive, green tea is the most suitable option of beverage for them. Having few cups of green tea, especially decaf green tea a day instead of decaffeinated coffee will doubtlessly guarantee our long term health.
