I recently heard about the study that found yet two more ingredients in red wines (some varietals more than others) that contribute to lowering blood pressure and cholesterol.... The names of them escape me but i'm sure you'll find them on a google search if needed.
The finding said that the ingredients did NOT exist in whites, though, but this isn't a problem for me as I favor reds strongly.
I say HOORAY, and lift my glass in toast to it and enjoy....
