As the public is becoming richer, people are more health awake today. In term of drink, green tea is considered as the healthiest drink as it is not only has the rehydrate effect, but it is also flavonoid rich that can guard our body against heart disease.

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

Research shows that green tea has really high concentration 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 comprises 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 therefore is believed to act the most significant role in the green tea's anticancer and antioxidant effect. Green tea EGCG is so abundant 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 can 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 boosts the level of free radicals in arteries sharply. Green tea EGCG will inhibit the enzymes required in the fabrication of the free radicals and thus protects the endothelium from spoilt by free radical. Hence green tea is playing an important role in controlling cardiovascular disease.

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

Moreover, cancer cells require enzyme dihydrofolate reductase (DHFR) to build DNA and spread. EGCG will inhibit the DHFR and is effectively blocking the grow of cancer cells.

Furthermore, EGCG can also accelerate the healing of injured heart cells, and as a result allowing quick recovery of tissues and relieving organs injury.

In conclusion, green tea EGCG has fabulous benefit in helping heart disease curbing as well as in heart attack damage healing. Therefore for those who are suffering from heart disease and those who are health conscious, green tea is the excellent option of beverage for them. Drinking few cups of green tea, specifically decaf green tea a day rather than decaffeinated coffee will absolutely guarantee our long term health.
