As our society is getting richer, people are more health conscious nowadays. In term of beverage, green tea is considered as the healthiest drink as it is not only has the rehydrate ability, but it is also flavonoid rich that manage to save our body against heart disorder.

Investigation on green tea drinkers show that they are significantly little vulnerable to a lot of sickness, from virus infection to chronic degenerative disease like stroke, cancer, heart disease and osteoporosis.

Research indicates that green tea has very high level of flavonoids (antioxidant) which consist of catechins and their derivatives. Antioxidant is the biological event that prevents the oxidation which will develop highly reactive free radicals. Flavonoids substance consists 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 upmost antioxidant activity of all green tea's catechins and thus is believed to play the most paramount role in the green tea's anticancer and antioxidant effect. Green tea EGCG is so rich 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 interface between the bloodstream and the wall of the artery where blood plaques may form, this is known as arterial endothelium. When cardiovascular disease occurs, a type of enzyme will speed up the production of free radicals in the artery endothelium, thus amplifies the level of free radicals in arteries intensely. Green tea EGCG will inhibit the enzymes needed in the fabrication of the free radicals and thus protects the endothelium from injured by free radical. For this reason green tea is acting a pivotal role in preventing cardiovascular disease.

EGCG also serves in halting the death of heart muscle cells after ischemia/reperfusion injury, by obstructing the onset of inflammation compounds (STAT-1) that will induce oxidative injury which kills heart cell in reperfusion injury.

Besides, cancer cells require enzyme dihydrofolate reductase (DHFR) to make DNA and multiply. EGCG will inhibit the DHFR and is effectively prevents the spread of cancer cells.

Furthermore, EGCG could also speed up the recovery of damaged heart cells, and in this way allowing quick healing of tissues and relieving organs injury.

In conclusion, green tea EGCG has outstanding benefit in helping heart disease curbing as well as in heart disease damage healing. So for those who are suffering from heart disease and those who are health conscious, green tea is the best choice of beverage for them. Drinking few cups of green tea, primarily decaf green tea a day instead of decaffeinated coffee will absolutely ensure our long term health.
