i have recently read about the fact that decaf is dangerous for heart then usual ones. What do you think about that?

Was it a medical specipalist who wrote about decaf? I don't believe decaf is harmful for heart.

I have heard about this too but i can't say where. \r\nIt is true that coffee is one of the controversial subject for discussion and you may endlessly bet about it. Just from time to time scientists discover new non less controversy info about this drink.
