Green tea ( EGCG )

I am not interested in immortality, only the taste of tea.

Green tea extract containing epigallocatechin gallate (EGCG) boosts fat release from cells.
Drinking tea makes your biological clock tick more slowly. The molecular age of men over 65 who drink tea is five years younger than you’d expect, write researchers from the Chinese University of Hong Kong. The telomeres of the men who drank more than three cups of tea a day ( a Chinese cup of tea contains 250 ml ) were 0.46 kb longer than the telomeres of the men who only managed 0.3 cups. This difference in telomere length represents "a difference of 5 years of life", according to the researchers. EGCG, a flavonoid in green tea, activates life extending enzymes in cells. EGCG works in the same way as resveratrol.

Studies:
Drink 3 cups of tea a day and add 5 years to your life
Drink green tea instead of water – and live longer
Chinese tea consumption is associated with longer telomere length in elderly Chinese men
Drinking 10 cups of green tea daily without smoking could add 12 years
