The paper, based on a “Million Women Study” in the United Kingdom, found that women over 50 years young having a drink a day increased their chance of breast cancer 1.1 percent compared with women having one or two drinks a week.
Wine industry watcher Lewis Perdue quickly raised questions, particularly regarding the researchers’ decision to throw out results from non-drinkers, assuming they were of “ill health.” Could it be that including this group would have lead to a smaller observed increase in cancer?
In any case, I think it’s fair to consider this quote in the CNN article from Dr. Gregg C. Fonarow, codirector of the UCLA Preventative Cardiology Program:
"Individuals that chose to drink should do so in moderation and because they like to, rather than expecting a health benefit."
The current recommendation from The American Cancer Society and the American Heart Association for those already drinking wine is one 4 ounce glass per day for women and two glasses for men. That roughly translates into splitting a half bottle each day for the average couple.
