EGCG, which stands for epigallocatechin gallate, is considered the most potent disease-fighting antioxidant in green tea.
Some of you may be concerned about your caffeine intake, but remember: Ounce per ounce, not only does green tea have only about a third as much caffeine as coffee, but the polyphenols in green tea slow the body's uptake of that caffeine. Consequently, green tea drinkers don't experience the same "spike" in caffeine in their blood streams, or suffer from the same "crash" that comes later.
In other words, green tea drinkers are more mellow!
