As our community is getting richer, people are more health understanding today. In term of drink, green tea is treated as the healthiest drink as it is not only has the rehydrate effect, but it is also flavonoid rich that can protect our body against heart disorder.
Research on green tea drinkers suggest that they are far little vulnerable to a wide range of sickness, from viral infection to chronic degenerative disease like stroke, cancer, heart disease and osteoporosis.
Research indicates that green tea has incredibly high concentration of flavonoids (antioxidant) including catechins and their derivatives. Antioxidant is the biological process that prevents the oxidation which will develop highly reactive free radicals. Flavonoids substance comprises of more than 30% of the green tea dry weight. Epigallocatechin-3-gallate (EGCG) is the largest prolific catechin in all green tea. It has the greatest antioxidant activity of all green tea's catechins and therefore is thought to play the most critical role in the green tea's anticancer and antioxidant effect. Green tea EGCG is so rich that a cup of green tea can have 20-35mg of it.
In our arteries, there is a one cell thick lining that works as the interface between the bloodstream and the wall of the artery where blood plaques may form, this is called arterial endothelium. When cardiovascular disease occurs, a type of enzyme will spur the production of free radicals in the artery endothelium, thus boosts 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 damaged by free radical. Because of this green tea is acting a vital role in preventing cardiovascular disease.
EGCG also serves in halting the death of heart muscle cells after 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 need enzyme dihydrofolate reductase (DHFR) to compose DNA and spread. EGCG will inhibit the DHFR and is effectively stopping the development of cancer cells.
Furthermore, EGCG can also facilitate the salvage of injured heart cells, and therefore allowing quick healing of tissues and reducing organs injury.
In conclusion, green tea EGCG has wonderful benefit in helping heart disease curbing as well as in heart disorder damage healing. As such for those who are suffering from heart disease and those who are health conscious, green tea is the top-notch option of beverage for them. Drinking few cups of green tea, primarily decaf green tea a day instead of decaffeinated coffee will undoubtedly ensure our long term health.
