Is yerba maté tea really bad for you?

Whoa! Really?! It seems there must be a lot of problems for the South Americans who consume loads of this daily? I haven’t read anything negative — any other info on how this is affecting people who have been drinking it for years?

The latest review suggests that the drying method (using firewood) may be to blame for the high levels of carcinogenic polycyclic aromatic hydrocarbons found in maté drinks, so a different production method may obviate this problem. That would be great since new evidence suggests that yerba maté may protect bone strength and improve blood sugar and cholesterol control in diabetics. I’ll let you know if I find more research in this evolving area.
