I had been looking forward to this issue. I think Tea is far better, due to it's high antioxidant capacity. It relaxes blood vessels and even lowers the Bad cholesterol. It even lowers cancer risks. Habitual drinkers (don't get me wrong - not alcohol) can use Tea.
Coffee helps in reducing blood sugar (avoid the crystals, please!).
It boosts the supply of Dopamine - which would help to cut down the risk of Parkinson's disease.
A cup a day or two is recommended. Maximum three. Don't exceed that. And dark coffee/tea can stain your tooth badly. Add a little milk and wash your mouth after drinking.
