I drink green tea because i find it refreshing and a nice change from black tea. I know it has many health benefits, but I can't isolate any...maybe that's because i take vities, exercise, am vegetarian (except for fish), etc. so I don't know what to attribute different aspects of my health to. I'm sure it must be a good health change from drinking tea with milk or coffee with milk all the time.
I like the lemon plus green tea. i bought some pineapple plus green tea and surprisingly, it wasn't bad.
Have you tried genmaicha? That's roasted green tea with brown rice. It's very good, a nice clean taste, with a hint of smokiness. You can usually find it in Japanese markets and some health food stores. A good brand is Yama Moto Yama.
All for now....
